i just got my 99 gsr turbo w/ stock @ 7lbs @ 215WHP tuned... its running alot better than before i got tuned... i got a greddy td04 18g turbo... and i want to race my brothers 94 LS turbo @ 6lbs only 235 WHP with t3 turbo.... i know he will prolly take me since he has a torque and the hp advantages over me... but i was wondering is there a chance i can take him? i only want to test out my car thats why haha.... 215whp gsr vs. 235 whp ls...

 

go to the track and find out.

 

torque figures would help. they matter a lot in how fast your car actually goes. besides, no one's going to be able to tell you for sure who will win. the only way to find out 100% is to race him, and yes like it's mentioned above please do it at the right location.

 

Race him at a sanctioned event and compare timeslips.
It's that simple.

It'll be a close race, largely determined by launch rpm and off the line grip.
Are both of you running stock (open) differentials?

 

just a quick question on the ls turbo vs gsr turbo. In one year i get my bonus and was planing on dumping 10Gs on the engine and turbo buildup. I currently have a LS motor and was thinking of swapping for a GSR motor. I was going to bore out the b18 and want to reach 500+ horsepower. IF i did the exact same thing to both motors will the number be identical or would the gsr motor exceed the ls? I mean at 20 psi + will the difference be enough to make a gsr swap warrented?

 

if both motors (ls/gsr) are full built with 10g's into the setup, the gsr will be faster then the ls.

lets say you weren't do internals:
Ls motor is just a motor that will get most gains from a turbo and is safer to boost at higher psi.

Gsr motor won't boost as high, but even at lower boost rate, this engine is still faster.

 

It would be a close race.

I got a 93 del sol with a 95 ls engine, with a t3-t4 turbo. Im rinnin 5 lb of boost and getting 180 w/hp

 

He'll beat you. 20 hp and more torque.

 

if you have a perfectly healthy motor i wouldnt swap it out. just build and turbo it like you said. you can always put a vtec head on later if you want.

 

I wasnt saying that he couldnt beat me. all I was saying is 213 w/hp is low for 8 psi.
