I used to run a little over 11-1 on a sleeved B20 block. Alcohol injection is something you might want to look into. Also ditch the Eagles rods, they will nto hold up for very long under that kind of pressure.

Good luck, you'll need it, and money for headgaskets, because they don't hold forever.

 

My old car

91 GST
9.1 comperession headgasket
Milled head with a good bit of work
tons of other mods
24psi on forced performance big 28 ported/clip 15degrees
revving to 8500rpm
Ran right along with modded c5's, High modded eclipses with larger turbos and more boost, turbo hondas with the larger t04e, and more. The car had the makings, if it wouldve had better management, to do 400+ to the wheels easy. ALL on 93, and nothing higher.

So, in turn, that was over 9.1, ran better than most gst's i have seen.

As for your questions tunning101, i will share my input.

well i still haven’t had a chance to put the #s up but as soon as i can i will. Yes high compression and boost don’t mix to well but i absolutely love it. I mean from my two dynos i didn’t loose any horses power at really low rpms 1000-2500 so driving around town is fine but by 3500 you had better clinch your *** because it gets rude, and at 7000 its still pulling all the way to around 7900 and thin it starts to fall off a bit. Damn i love it but the only problem is like what was posted i have to watch out for bad gas but a lot of extra safety precautions where taking into consideration before i took it out on the street.

You will be fine with the gas. Get yourself a good tuner. You prolly will spend more on the tunning, but if you have proper management, you will be able to do it. I suggest a cosmetic headgasket to lower the compression to around 10.5. If you want to do the 11 though, go for it. My buddy Jack (p1 auto) had his ITR motor, stock might i add, 12psi+ on a larger turbo, daily. GREAT power, and ran like a champ. I have seen tons of Higher compression setups, and i say go for it, but i also agree with adseguy on the who low vs high thing. Its all on preference. Everyone will tell you something different, but we will all agree, you need to think about management and fuel b4 anything. Also, start looking for an above average tuner in your area.

One of witch is i tuned it a little on the rich side because down here in Texas the weather changes on a hourly basses. and the other problem is i cant just turn up the boost like a lot of people can for the simple reason that i have no room for error but we did put a tank of 108 octane in it and sprayed a 100 shot on there manly because everybody said it couldn’t be done but it was basically point less since all i had where my ridiculously bald nittos on it lol. But ya all in all she has turned out great but i was really wanting to see if there’s anybody elce that posts on here that runs high compression like 10.8 and up so i could see what there #s look like and im not trying to start a war between high comp. and low comp. Just trying to let everybody know what its like. One more thing for the record i raced a guys car that was at the shop he had a fully built low compression motor running some where in the neighbor hood of 18 pounds and i still got him by a hood length and off the line i destroyed him but he caught me at the top of 4rth when i ran out of steam lol also for the record his car put down 331 hp and like 253lbs of torque.

Are you comparing your motor all motor vs his turbo setup? If so, this will open a whole new can of worms.

I hope my advice helps, but im in no way as knowledgable as most of these guys in here. You need to figure out whats best for you, then buy the management and run it.
