The MSD BTM would work OK, but it has no way of detecting detonation.

Yeah I hear yeah, its just not in the budget for much else. Also my MSD box has a Timing Retard function, I wonder if I could hook it upto a knock sensor? or possibly just a hobbs switch to pull x ammount of timing at full boost?

So far including the purchase of the motor and the head rebuild I have yet to spend over $500. Alot of DEALS and alot of parts lying around. I have looked into building a DIY knock sensor though so well see.

Just got my fuel rail and injector bungs to convert to MPFI. Getting a turbo similar to yours. Hopefully I can make as good of progress as you have. I have more on my plate then I can keep up with so.... I might be able to get it in N/A and run it that way to get things broke in.

I did order a v-Band flange setup to hook the exhaust to the Downpipe. That should be here tomorrow.

I did some more work on sealing up the carb, removing the choke, ect... the Down Pipe is wrapped and you can see the 02 location. V-Band will be here tomorrow, and my fuse panel arrived so I can rewire the gauges and 02.

Looking sharp!
Are you ready to install your new carb bonnet & intercooler, or is that on standby?

Also ,take notes on when your boost comes in after you install you exhaust system.
Goodluck!

No intercooler yet, but a new carb hat should be here shortly, wont be driving it again till that does arrive. I will watch that and plan on installing a cutout to bypass the exhaust when racing.

As for internals.... its completely STOCK. 230ci with 75,000+ miles, just a rebuilt head, petronix ignitor, and an intake.

Well looks like I found an intercooler. Smaller one but bar and plate style and should be easy to find somewhere to mount it. Its a Saab 900 Stock IC. should work just fine for my low boost application, now just where to mount it.

If you run that intercooler I would install a Spal electric fan mounted to it.
Cheapest place to buy from is www.the-fan-man.com
1(866) 435-6477
I put one on the wifes Jetta intercooler & made a noticable difference.

The Spal fans are really slimline if you are hurting for space.
There are several companies.
Slips my mind right now ,but you can install a probe, my friend runs a small wire w/probe on the end of the wire into the airstream of his intercoolers inlet & outlet, & uses a westech dual temp gauge.
IIRC

Yeah the 9in we have is a slim one, used to run it on a transmission cooler so it should work perfectly. Ill look into finding a probe to watch the air temps.

RevOD,,,,,


I was wondering what kind of wastegate did you use & if you had any closer/better pics of your install?

Also I picked up a carb hat over the weekend in Kansas City. Most likely a dual fuel hat for a propane system? But well make an adapter and it should work out just fine.

Nice pics!
That does not look like the carb bonnet you left a link to???

Are you going to run a pipe from your wastegate into your exhaust system, or just leave it open?

Yeah well see once I get it completely mounted, going to route the charge pipes right under the radiator support and back up to the turbo and carb. Ive also decided to keep the PCV system, with a check valve and a catch can, the rings on this thing are bad, without one it just mist oil out the breather even at idle.

Almost finsished rewiring my accesories to the dedicated fuse panel I purchased also.

does the fuse panel have anything to do with the turbo functions or is for the ignition/accesories?

It may not last long.
Well we didnt know they were that bad till we got this far along. I would rather finsih up all the small details and then worry about re-ringing it so it can be an easy in and out operation. Plus who knows what else we may find once we get inside it might turn into a full on rebuild and I dont plan on spending that money on a 230ci

ok, kind of threw me off for a second. so if the things inside are bad and require a rebuild, which you dont want to do, what becomes of the whole project?

Rebuilding a 250 or a 292 block, not a 230. If im going to drop $$ on a rebuild it will be with a bigger ci motor. Plus i have a buddy with a fresh 250, cammed, with a roller rocker head that im trying to get him to sell me. With that motor I could swap on forged pistons, rod bolts and go.

so from the knowledge and experience you've attained through this project, running a 250 would be nearly identical to the setup you have now? btw, is there a stock forged piston for the 250 (or 307) or is that all aftermarket?

Exactly identical, only difference is the bore x stroke.Yes the 307 Forged Piston will work on the 250. This would even work on the 292 that just has a a bit higher Deck height IIRC

I bought the motor locally, the turbo off a GN Forum, most of the tubing and flanges from McMaster-carr, a few things off ebay and the rest is stuff I had lying around or from the local parts house.
