Yeah a buddy of mine built his V8 turbo headers from these. So I figured i would give them a shot. I got them from McMaster - Carr ordered 5pm and got them @ 3pm the next day.... now thats service.

With thoughts of making a header, what about a simple Log Style manifold? Huber Performance here locally in St. Louis uses one on his 9sec SVO Mustang.

Log type manifolds seem to work OK, but,,,, for all out power a nicely designed tubular manifold will make you some more HP.

Innovative turbo sells turbo manifolds for the 194-292 engines.

Nice pics!!!

If you pick up some books on turbocharging, you will find log type & nicely done tubular manifolds,,, but they all agree, a properly designed tubular turbo manifold will net you more gains.

If they did not see any improvements w/a turbular header manifold,,, then you would have seen log type manifolds on Formula 1 cars.

revod, i'd say go for it and make the manifold! hank is right a tubular tuned header is best. but you are not building a all out race motor. it would work fine in your application. i would recommend making a jig to make it easier to fab up. if it works good, like i think it will. you may be able to sell these elusive manifolds. tom

yeah what I need is to get a cad drawing for the flanges so my machine guy can make me a set to start with. Ive got auto cad just gonna have to start measuring it up.

No like the MSPAINT drawing i had above. You think its viable to merge the 2-3 and 4-5 pipes into one and dump them into the log? Do you see this creating any issues

RevO,

Merging those cylinder exhaust ports will not hurt anything going into a log type manifold.

Manual boost controllers are ok, but your boost will vary from day to day depending on the weather conditions.

A good electronic boost controller would be a better way to control boost.
I know they are kinda expensive, but they are programable & worth the investment.
Two cents

Yeah to start the manual will be ok even a bit of variance to start. Once i get it all figured out I will pick up an electronic one.

Cool,
so what all is being done to you cylinder head?

You might want to bump up the valve spring pressure a bit,,, since you will be added boost pressure to the backside of your valves.

Hardened exhaust seats, new guides, valve grind. Just a basic rebuild. By bumping up the valve spring pressure you mean swap in stiffer springs?

You can install different springs or add shims(not recomended really,since springs are pretty cheap & they will be new)
It's up to you.
You can run stock four barrel head springs. Good choice in your case.
A little bit stronger factory Z-28 springs or others do not cost that much. Those would be a bit too much(Z-28 springs)

so you can use a std z28 spring on these without modifications? I might pick a set up and have him install them if thats true.

How about these?

SEAT PRESSURE
110 lbs. @ 1.750"

OPEN PRESSURE
325 lbs. @ 1.200"

COIL BIND
1.150"

FREE HEIGHT
2.030"

NOMINAL LIFT
.490"

MAX. LIFT
.550"

RevOD,,
I would use the stock four barrel head springs.
Like for a 1969 Chevelle/Camaro etc.

With you running a stock cam ,those springs you had on previous post, those are too much for what you need.
You could run the Z-28 springs,they usually do not pull the pressed in studs, but I would set them @ 80 lbs on the seat.

But like I said before,just install the 4 barrel 350 1969, head springs,these springs are fine for your stock cam & running a turbo.

If those are for the stock four barrel heads from 1969 era or so, then yes.
Heads like the 041's 441's those are the last three numbers on those type of cylinder heads.

RevOD, have you thought about running methanol injection?
If not you might want to look into that also.

RevOD,,,
I keep forgetting to ask you.
Are you going to run an intercooler?

I know you are working on a low dollar install.
If you are thinking of a intercooler, I would think about getting a used Volvo intercooler from a junkyard, they are pretty darn big & flow decent.
Intercooling plumbing you can get pretty cheap on Ebay, they come in prebent tubing w/hoses & clamps.
Might have to put on rolled beads on the ends of the tubes so the hoses won't blow off.

Let me get back to you on that spring question question.

When you say a probe intercooler,are you talking about a Ford Probe?

I would not suggest using a Ford Probe intercooler.
It is designed for a 2.4 liter.

Generally speaking, factory intercoolers are too small to begin with. They just throw in an intercooler that will fit(for packaging purposes),not one that will cool the best.

I know what your saying that it will fit perfect for your car,,,, but take it from me,,,, it is too small.
A Volvo intercooler is as big as the radiator,it is overkill pretty much for there size engines.

You can pick them up at junkyards & tell them it is a radiator,(usually radiators are cheaper than an intercooler.

But if you want to spend a little more for a new intercooler, Ebay has tons ,,,just look for a bar & plate design & one with the flow requirements you are looking for with the inlet & outlets where you want them.
My two cents

There is unfortunately no way to make one that large fit in my car, it least not in front. The grill is too close plus I would have to slice up the hood latch support and re brace it some how and that I do not want to do. And with the 6 being so long I cannot move the radiator back and put it in front of that. So Im stuck wither running a smaller one or running none at all. There is literally no room in the front of the radiator without doing some major surgery....

i had to remove my hoodlatch assembly. the requsite hood pins look good. my intercooler is a common aftermarket type. finned area is 18 long by 6 tall 3.5 thick and 2.5 inlet and outlet on same side. i did have to cut some holes in my rad support to route the tubes and alittle notching for total cooler clearance. all this in a 65 elcamino. you can make one fit. tom

Oh I could but I am not installing hood pins lol.... Like I said I could do some rebracing and fit one about the dimensions you said and keep the hood latch, just unsure if I want to.

if you keep the boost pressure below 6 lbs you may not need a intercooler. tom

Here is my finished Turbo Outlet Flange. Had it custom cut by MC Motorsports. Its an odd ball bolt pattern so I had to send my housing off to him to get it cut.

Now both housings are at the Powdercoaters its getting 2000deg Satin Black on the Hot side and Black Chrome on the cold side.

Looks nice!
Did you want to weld a V-band flange to it first,then get it coated?
V-band set-ups work great! No gaskets, easy to take off & put back on.

The flange is a separate piece then the housing. It will just bolt on, and the pipe will be welded to that flange. Then once its all welded up the hotside pipe and down pipe will be coated also.
