welcome, nice to see you posting on our site.

so far you have a nice group of parts added up.
here is a few questions and comments.
what car is this going into? i think i know , but just to let everyone else too.
that is a pretty big cam to be mixing with a 700r4. 1st , i do not think it will take the power and second the O/D will hate the cam. my suggestion would be a th350 and a bolt on O/D if you want O/D.
also, what rear and ratio? tom

Tlowe...

I have had a lot of people mention that...which i respect and have taken into great thought..... another builder has recomended a 200 r4 which can handle the power which i am seeking right now, i will let you know the specs and all as soon as i have conformation.......it is supposed to be the best thing since sliced bread but i do not belive the hype....will let you know asap

sorry i forgot to add the most important part of what the engine is going into.

1967 chevy nova 4 door

i have completely upgrade the suspension to what a stock 4 door can hold....cpp mini sub frame...church boys rack and pinion....qa1 coil over shocks....global west subframe connectors and del-alum ahackle kit.....upgraded 10 bolt...qa1 shocks in the rear...

my goal is to present a stock looking car other than the rims and dust the competators....we will see....

if not i have a pro stock ready 67 nova wagon made to a 2 door and choped 4 inches to compete with this...

sorry im slow tonight i need to read more...4:10s in the rear

ah, 4.10's, the o/d will like that alittle better. it will help get the cam out of the low rpm overlap. i also agree that a 200r4 will give better ratio's. the only place i'd buy one from is the real art karr (sp). somebody bought his old bussiness and i would not buy from them. tom

turbo nova,

I would like to know what your goal is as far as HP,1/4 mile time & so-on.?
1/4 mile car,top end? daily driver,good street manners.weekend car,strip only,,street/strip,,,etc.. what is more your goals?

Running a big cam will not hurt the 700,if anything, running a big cam will give you less torque at lower RPM's for the most part,, & torque is what kills transmissions,not so much HP.
As far as your turbo exhaust manifold.
A plane log type manifold will work just fine.

Look at this guys stock modified manifold making a lot of HP.

530 hp@5300 and 588 lbs@4000rpms at the flywheel, with 21psi boost and E85.

https://www.inliners.org/ubbthreads/ubbthreads.php?ubb=showflat&Number=46662&fpart=1

IIRC,,,A guy in Brazil has made 869 HP w/the SPA manifold ,same as yours,, on a 250.

That is my post also at sns here a picture of my manifold i am building who knows how it will work

http://www.stevesnovasite.com/forums/showthread.php?t=112302&page=3

Welcome to the site.Looks like a strong build with all those go fast parts. I was wondering what kind of turbo are you going to run? I see a T3 ar70 turbo in your list ? Any more specs on it?

That is all I see, I cannot open any pics .
Pics here please.

MBHD

Here are a few pictures of my turbo manifold i am building.....its not complete yet and im not to sure if it will have good flow characteristics but im giving it a try...im having custom stanless steel exhaust flanges plasma cut right now so the plate it is welded to is only a mock up. Also a picture of my adjustable timing gear.

Looks impressive.

Is there enought room to complete the welds with it assembled like that?

Is there room for your intake still?

Verneer lock cam gear looks very nice.

Looks nice so far.

I read in your other post, you are only looking to make 400 HP???

If that is the case,this turbo manifold is a bit overkill.

You can make a plane jane log type manifold for 400 HP.

But since you are making a nice manifold & you are probably having fum making it,as I would also,keep it up,you are doing a good job!

B.T.W.,those are stainless schedule tubing,how much have you spent on materials so far?

MBHD

Sorry for the gigantic pictures...i did not know they were that big.....well the manifold so far in materials is close to the 400 dollar mark, that stainless tubing is not cheap. When i go back to tig it up i will take one complete tube off at a time and weld it solid and put it back together. It clears the intake fine im just worrried about car fitment thats why i have not finished it yet. I will keep you posted with smaller pictures this time...

well the turbo i have to say is a cheap one, it was about 350 to 400 bucks oil lubricated. This is more of my experimental turbo i have plans to upgrade to a water cooled one after i work out the engine bugs.

in terms of horsepower i am amming low right now and if it comes out to be more than thats great....i have ran it through the desktop dyno and it has given me some crazy numbers so i will wait and see when its done so i do not clame anything it will not produce.

I saw it on sns...but the thread dies in May.

So how far along is this Turbo-Motor? Have you had it up and running or bench tested it yet?

Still plugging away with some parts here, put the deposit on the head today, the description is as follows....

Custom Stage 4 Turbo Roller Cam head

STAGE FOUR Hot Street Econo; Lump Port Street Head, All included in Stage one, two, and three; with the addition of a performance valve job. and PC seals. 12 High Performance intake and exhaust valves 6 stianless intake and 6 Special alloy Inconel exhaust Valves .

Turbo nova
I did as you asked. photos of 640x 480 Or smaller is ok for most web site to veiw.And not look way to big. Hope this helps.
Great Job by the way. $\:\)$

Here is a long overdue update for the site: not sure if others have seen my post on other sites...

well here are some updated pictures for you, this is a test fit only i have to take it all back out. i will run all the pipe and intercooler after i rotate the turbo to the correct orientation.

Here is a picture of the MR hotrod 6 head

Well, here it is a few pictures of the head with the rockers and stud girlde on it.

The piston order is going out this week, i should see them again in about 4 weeks. specs as follows

JE pistons
-8cc JE 2618 Alloy Forged Pistons with wrist pins
-Total seal gapless top rings
-High heat ceramic coated crowns and moly coated skirts
-Heavy duty wrist pins
-contact reduction grooves

Saw this same post on stevesnovasite. Can't wait to see what numbers it makes.

Looks very nice!

Great job!

MBHD

I think you are going to make much more power than you are thinking.

I would also recommend the 200-4r unless you already have the 700r4.

I really really want you to put steelies with dog dishes on it. That car will make millions!

Hopefully so,

I have so man other freinds spend lots of money and produce low numbers.

We will see ill keep my fingers crossed.

The whole goal of this car is to remain stock looking on the outside for the "sleeper" approch.

Thanks for the comments

Here are the pictures of my turbo pistons.

I went with diamond pistons over JE because if i have a failure i can purchase just one piston if i want it.

specs:

Special coatings on both the crown and skirt.

Bore: 3.9350
Compression height: 1.365
Effective volume: -5.1cc
Valve depth intake: .177 exhaust .169
double spirolox
piston weight: 543 grams

i love it keep the pictures and info coming

Man it's like christmas looking at these pictures!

A few more up dates for you

Off to the machine shop:

Basic list of operations to be completed:

1. Drill for Oversized pushrods- need to be 3/8”
2. Damper needs to be recessed onto the crank by cutting a .250” relief in the gear to pull it on to both keyways
3. bore block .060 over with plate( being shipped as we speak)
4. boil block install cam bearings and freeze plugs
5. align hone block
6. surface block
7. balance crankshaft assembly internal
8. size wrist pins to piston
9. polish and mag crankshaft
10. engine assembly (on this one im letting the shop do the first assembly so i can get it properly recordered and checked for any futture issues)
11. o ring the block for my stainless wire- no rings on the head...

I will be sure to get some pictures of the whole process, i will not be dynoing the motor untill later in january/febuary time frame.

It will take a while to get all of the final parts, mocked up/fabbed up after it is built.

Also a new turbo:

I mocked up the new turbo to my cast iron manifold. Its a T4 turbo and a T3 manifold so i had to get and adapter the would move it up a little. The T4 can be adapted directly to it but i still want the option to go back to a T3 if i so choose.

Turbo specs:1.05 A/R

Compressor Size: Inlet = 4 3/16", Inducer = 68.7MM, Exducer = 97.8 MM, Trim = 69,A/R = 0.66, Intake (ID / OD) = 2.25" / 3.25"

Turbine: Outlet = 4", Turbo flange = T4, Downpipe flange = 3.5" V-band, Inducer = 87.4 MM, Exducer = 77 MM,Trim = 92, A/R = 1.05

Its a little big but we will see what it can do when it comes for the dyno day.

the main stud caps have been machined down to allow for the ARP stud gridles to fit.

Also the block has been Bored 60 over.

The crankshaft will be sent to a shop up in tennesee to get ground down

Uploaded with ImageShack.us

Looking good!.

I am just thinking the turbo is a bit big also,but try it out & see.

Is your turbine housing devided?
If so,might want to use one of these from my friends shop.

http://www.theboostdepot.com/index.php?p...emart&Itemid=26

Just a thought anyways.
You are getting a lot of nice parts,someday I will buy also.
Keep it going!
One other thing,can you get a stub stack for your carb? Might help w/flow.
Sorta like this: http://www.knfilters.com/Racing/stubstacks.htm

MBHD

Still waiting on the machine shop....i guess they had to send the crank to tennesee to get polished.

Hopefully i will have something usefull to update on this build shortly.

Went by the shop today to check out some progress.

The crankshaft was back from the shop and it looks good.

The the gear has been recessed on the crank to allow the harmonic balancer to pull into place.

The gear has also put onto the camshaft.

The block has been bored, honed and o ringed.

Hopefully it will be finished in a couple of weeks.

Uploaded with ImageShack.us

Did you drill & tap the end of the crankshaft?

If not, I would suggest a BBC size damper bolt.

Looks good ,keep it going.

MBHD

The crank has been drilled and taped.

Here are a few more pictures of the build.

Engine assembly has begun, the short block is about finished,

the engine should be buttoned up by the end of the week.

I still have to get it home before i can run it on the dyno.

a little more fab left

Uploaded with ImageShack.us

Looking real good.

What ever happened to your weld els turbo manifold?

MBHD

still working on it,

i want to get the engine up and running first and then i will look at finsihing the manifold

Cool,
how about a few pics of that manifold? I think it looks great.
Thanks

Turbo Nova,
got some pics?

MBHD

Just got it back from the machine shop, i am now trying to piece it all together. note, carb is just sitting there for mock up of turbo pipe work

still need to send the mounting plate off for modification

here is an update pic

Uploaded with ImageShack.us

Looking great!
What do you need to do to the mounting plate,for the carb?

MBHD

Yeah i need to get one for the carb

i am about to send it off to have it reworked

it aligns the carb fore and aft instead of side to side

Twisted6, AKA Larry sells them w/linkage I believe.

MBHD

Here it is:

MBHD

here are a few pics of turbo nova's New lower Alt. bracket to help him get things moved forward & aligned.

Looks good!

Nice work Larry!

Thanks.
He need a much longger then stock set-up because of the belt drive he is useing.I have a few in stock size that are adjustable as well and a few that the Alt. sits a little higher up then stock. like this one.

which is not finished 100% yet.I have a few other things i am working on for him as well.
But again thanks for the input.

Cant wait to see it on it will be a great addition to the engine.

Here is his upper Alt bracket and his Dist hold down.

This is the finished lower mount.

great work guys
i am dreaming or some day braving up and doing the same thing

What kind of power is this work of art going to make?

we'll know more on that once it hits the dyno.

Here are a couple more pictures of the progress.

Installed belts and alternator brackets-made by twisted six, also the distributor hold down.

next i installed a peterson breather, installed a oil acumulator off a nitro funny car, welded that to the valve cover, installed the BOV to the charge air pipe.

Still have to finish the upper mount for the alternator. also i have to finish some piping for the oil system to the turbo

Looking very nice!

I forgot the specs on your turbo. Did you post them already?

MBHD

CRAP! That is a beauty! What is that COPPER colored canister mounted to the valve cover?

I cannot wait to see a video on this one!

I love all of the anodized bling.

Thanks for the comments.

The Orange canister is a oil accumulator. This came from a company called AFT, they make transmission clutch parts for nitro funny cars. I adapted this to use it as an oil accumulator.

The only reason i will run it is during slow down or shut down conditions. The turbo oil pressure will be low and the turbo will still be spinning. This will store just enough air pressure to discharge this oil to the turbo and prolong the life of the bearings. If the engine is running all it will do is overcome the air pressure and hold oil.

you can find these parts on sites like

Thanks for the reply, i cant wait either....

right now its alot of nickel and dime nuts bolts hoses and gaskets...

Here are a couple of teaser pictures of the oil pan. the bottom sump has not been welded on yet in these pictures or the -10 AN drain lines.

Hopefully this will be sitting in my garage wating for me when i get home.

Beautiful work. I like the idea of the oil accumulator to save the turbo bearings.

Looks nice.

Who made it & how much? If you don't mind.

I'm looking for a an oil pan.

I sent him my old track pan and he set up a jig to make inline six pans.

$500 shipped was what he charged, one of the best prices i have seen for a aluminum pan.

I also have a accumulator for the engine as well, its about twice as big as the other but is still a AFT accumulator.

Just wondering if you have the oil pan at home now. I would love to see some pics of the final product!

All of my searches so far have come up a big fat zero so I am thinking that I need to call Charlie.

Sissells sells aluminum oil pans also.

Both are pretty. $\:\)$

hank, do you know if Sissel makes wet sump pans too? (the one on their site appears to be dry sump)

As far as I know sells wet sump pans also.

I talked w/him before a long time ago about aluminum pans & @ that time he said he sells them.

I will try to post some, ive been tied up with work for a while . If you do go with charlie send him your old pan to match the bolt hole pattern. The pan i sent him which was a circle track pan was a little bent so i had to midify a couple of the holes.

Yes Sissell does sell them but he out sources most of his work to

http://www.billetfab.com/pans.htm

He makes his pans/valve cover.

I spoke with them but to do a two piece pan with the ball bearing oil passages is like 1200 bucks.

Im not sure if he still send them out but when i called last time before i started with this pan from charlies he said he did.

Charlies pan came out great with supurb quality. Any issues i had with bolt holes were fine from sending him a crappy pan to work with.

I thought Mike K uses these guys?

My wallet had a heart attack after looking at your specs and pictures, however I am liking it a lot!
Monster cam! Does your head flow that well?
This is obviously an all-out effort! Is that adjustable cam gear made by Johnson of Johnson lifters?
Great to read, Regards W

Sorry I meant this place is what I believe Mike K uses for some products.

Some new pictures of the oil pan installed with some other parts.

All that is left finish welding reduced for wastegate, vacume/boost lines, motor mounts, dyno

Work has been more than crazy lately so ive had no time for progress.

Uploaded with ImageShack.us

Very nice looking!

Just something to think abou for the exhaust downpipe, normally, you would want nice gentle bends, (like mandrel bent tubing) no sharp edges & have the tubing as big as possible.

Mine is not the greatest, I made the joggle to clear the steering box, it is smoother on the inside than the outside.

MBHD

Wow, need to get my sunglasses out to look at it!

One problem I see, the oil drain line on turbo should not have the lower hanging section. It hangs lower than the conection to the pan. The oil when leaving the turbo is all frothed up and needs the easiest route possible to flow.

Keep up the good work! Tom

yes i realized that as well, i need a elbow and a shorter line and that will do the trick.

Wow that looks great!

Lots of ideas there for my little project.

Paul

Finished fiting the front together and put her back on the ground

Also Threw the engine in today to check fitment, for the most part everything fit, its back to the drawing board with exhaust but ill figure it out.

Uploaded with ImageShack.us

Looking great!
Why back to the drawing board on the exhaust? What happened?

If you do not mind.

MBHD

Hi
Have followed your project with big intrest from the start.
Looking realy good!
Have you done som progress?
Looking forward to updates!

T.T.T. updates?

MBHD

I'm really liking this thread!
I am working on my setup for a 1965 Nova... can you tell me more about the front frame (specifically the QA1 struts)?

I would like the OP (original poster) to come here & post some updates myself.
The guy spent some $$$ on that ride.

Very nice taste I might add.

MBHD

It has been more than a while since i have posted, I have still been working on my project ever slowly over the years. Here is updated spec sheet with a few pictures. More to follow

The engine has been started. I did not put much in the way of boost to it yet but here it is.

Note: all the hoses all over the place are temporary just for start up and tuning.

Well I have upgraded the turbo. I put a call into precision and they recommended the one listed below based on build specs and potential power requirements.

Also went with a precision wastegate as well.

Turbo: Precision Turbo T4 6466 SP CEA-2-BB1w/TH8166a .81AR
Compressor Wheel: 2.535” inducer/3.410” exducer
Turbine wheel: 2.920” inducer/ 2.600 exducer

Wastegate: Precision Turbo 46mm waste gate 15 psi regulated

I did not take a picture but i have the install of the boost controller underway as well.

BOOST CONTROL: NLR AMS-500

Also I ran a test on my RACEPAK IQ3 data logger dash and all looks good.

Only other updates are and new drive mandrel from aerospace components was installed which allowed more clearance between the radiator and the
pulleys.

So For those wondering if this build will ever be finished the answer is yes..I have found some time to get back into the project over the past month and have been working closer to finalizing everything.

-The Vacuum pump has been installed but not yet plumed up- Should be done this weekend

- I have decided there is no way i am finishing this car without Air conditioning, It is just way to hot down here. This in turn present a whole new set of problems with the pulley system.
- My solution going forward will be modifying the steel ac compressor and Alternator brackets to slide forward to align them up again. Looks doubtful if I will be able to use my t6racing one.
- Second purchasing a BBC drive mandrel with a V belt pulley right on the damper area to free up some room.....more to follow on this.

Installation of the rear suspension is near complete

Installation of the will wood spindles and brakes is complete.

Figured id come back for my every few year post....

Well first off a video from last year of it running

https://www.youtube.com/watch?v=FGnwFIZk0H8&feature=youtu.be

Here are some pictures how the engine currently looks and some other mods and pulleys set ups...

Well, sir! It looks fantastic! Glorious job!

Did you have any issues fitting the rocker cover? Mine does not want to clear the roller rockers ☹️

That looks like a Kirby cover So their won't be a issue with the rockers. Great video, Sounded Great Like a Beast.

Yeah my cover is Sissell Racing one so it all fits good.

Adding a turbo sure complicates things but it looks great, and the power curve has to be phenomenal with plenty of torque!

Looks and sounds wicked!!
What kind of power you making?? What made you go with the Clifford intake over the Offenhauser or PES??

I noticed you changed the charge pipe routing... was this done for looks?

How’s does it run? Are you happy?

I’m stoked to being installing my built engine... only took 2.5 years to build. Can’t wait for spring!
