what are some typical dyno numbers for this?

[formula94lt1]

Stock heads, shortblock, cam and turbo... just boltons and intercooler upgrades, Also any suggestions on any GN performance websites I can sheck out to learn more about the different mods you can do to the engine? Ive done some searches and havent found anything really.... Thanks

On mine w/112k mi. last year dyno'd 248.6 rwhp@ 3k rpm - torque 407.8 @ 4100 thru 4800 rpm all stock inside,open dump,36 lb inj. Lots of good info out there for building power ,alot of the "mods" are not real expensive either. Just research thoroughly before spending the money.

Sweet site guys, Ive been looking at it for a little while, learning a lot of stuff. What im trying to think about doing is putting an 86/87 motor in a 76-87 chevette. VERY inexpensive and prolly alot of fun. I figure if you can put a stockish 500 cube big block caddy motor in one with nothing special done and run a 10.4 a gn motor would be pretty promissing. Dont mind learning about gn's and regals either...

the turbo is all the power when talking about a stock GN motor.

I ran 11.60's@114mph without locking up the TC with a stockish motor (small cam/home ported heads) and stock turbo with decent FMIC. With more tuning and locking up the torque convertor it should've gone 11.30's or faster @2810lbs.

Add $40 valvesprings, front mount intercooler (FMIC), 57lb high impedance injectors (no ECM mod needed), 3" downpipe, quality chip for 100 octane+ (these motors really wake up when you turn up the boost past 25psi on a larger than stock turbo), and finally a larger turbo.

Friends car with 90K+ mile stock motor with $40 upgraded springs, 50lb MSD injectors, 21* chip, 100 octane (2 gallons of 116 to be safe), 29psi!!!!, PTE FMIC, TE-64 turbo, 3" downpipe made 526rwhp/658rwtq. He has been running in this state for nearly 4 years and has probably 200passes at the strip with this combo. He only in the past 2 years has been running 25psi+ with no ill effects. It is all in the tune and no knock.

That Chevette will fly.... but you should look for something else IMO. http://www.turbobuicks.com has a hybrid section with GN powered cars..... some very fast ones too.

Thanks for the info man, ive seen you on another forum...forget which, but if you dont mind me asking why not a chevette? Bet that rx7 flies...

EDIT: OH YEAH it was the rx7 engine swap site...torque central, I was thinking about that a while back but realized I had no money BTW didnt see where on this site it talks about the turbo 3.8 in other cars...
