After many hours of messing around I have it running pretty good. For now, the vacuum advance has been eliminated... too much timing at cruise. I bought an HEI for it but haven't installed it yet. My carb hat and BOV flange were leaking under boost. I made new ones! Never noticed the choke linkage coming through the body... removed it and sealed It yesterday. Then the seal blew out at 5 psi ![frown frown](/ubbthreads/images/graemlins/default/frown.gif) New seal this morning before I left for work. Got rid of my Flowmaster. Now I have a thrush straight through. Tail pipe to be installed tomorrow... the only part of the exhaust I can't do. I need to vent the crankcase more. It it pushing oil out under boost. Don't know if I should nix the pcv and replace it with 2 air filters.

What would it take to get 400 HP out of my stock 194? Here's my thought... j & s safeguard meth injection fully done head 15 psi
would that about do it?
I have a good grand national engine available to me and I'm weighing options.

Unless your looking for a one time shot and not concerned with longevity that might work. Otherwise, O-ring the block, head studs, main studs, probably more camshaft, minimum of ARP rod bolts, preferably H-Beam rods like Eagle or Scat. Might be cheaper to get the GN engine.

IIRC, This: https://www.youtube.com/watch?v=EVJyHrNzXG866 Nova had a completely bone stock GN engine that had a lot of tuning done to it. MBHD

The turbo I have is not right for me... I'm now finding information about it... the turbine is 1.15 A/R compressor is .60 A/R I don't see ANY boost until 4000 rpm ![frown frown](/ubbthreads/images/graemlins/default/frown.gif) I'd rather not blow up my engine by turning it too high. So, I found a brand spanking new in the box turbo a short drive away. It has a .63 A/R turbine with a .70 A/R compressor. Think this one will be more impressive. Hope to have it running in the next two nights... just waiting for the exhaust flange to arrive.

Well. She's a runner! Pulls like a school boy, to be honest! I think I am running out of fuel after a 5-6 second full throttle! 6 seconds in I'm at about 55 mph. On the highway, a full throttle blast from 60 resulted in similar fuel starving at about 90 MPH. I imagine it is running out of fuel because it reacted almost identical before I had the boost reference on the fuel pump. Still don't have an a/f meter living on the edge, but at least I am aware of it!

How much boost is it seeing? Turbos are fun! This is on a little 194, Correct?

Correct, Tom. I see a consistent 6 psi from about 3500 up to 5000.
Though, I have not heard my wastegate open (it is vented to atmosphere). It does have a 7 psi spring in it.
I have not rechecked for leaks since the new turbo.

Let's see pictures of it now that it is a runner.
How about some video?
Be careful running it lean, piston destruction will be certain.

Did a road trip to Ohio on Friday. Took the Nova. Averaged about 18 MPG. 70 MPH @ 3100 RPM. Not too bad! I thought the RPM would be lower. Guess the gears are not what I thought. 3.3ish?
Still need to put some more pics up... Sorry for the delay. Not sure on how to do the video.
It's funny how seeing the old 6 with the turbo blows some people's minds and others are like '7 psi?! Weak!'
Wondering if the 194 would take 11 psi. Or even 15. I haven't got the intercooler yet, which would be a must for more boost. Like to do the meth injection too but no dollars for that.
The 4200 is becoming more enticing every time I think about it... Need more! It IS addictive!

Sorry, Tom! We were on a very tight time line! Being held at the border put the squeeze on!
Educated guess.... what am I looking at for power out of this setup?
194 ci Offy intake (heavily massaged) Holley 500 2 barrel. 7 psi 28* total timing
and how about when I add the intercooler and a meth injection kit?

I'm very glad I stumbled across this thread. I'm contemplating just such a mod to the 194 in my 64 Nova for this year's hot rod power tour. One of these days, I'd like to get around to a full engine build, but for the time being, I was wondering if I could slap a turbo on the old girl and not blow anything up.

SNAG. I cannot run my exhaust (without going through the inner fender like a fender well header) because of the transmission kick down rod. How did you resolve this clearance issue?

The whole build was surprisingly simple. I removed the kick down rod on the powerglide (fully expecting it to grenade) but have put almost 200 miles on it without fault. I removed it for the clearance issue, but didn't hesitate too much because it didn't seem to work anyway! One thing I wish I'd done is move the turbo forward another inch or so... would've solved ssome clearance on the shock tower.
