Boosting a GSR.
 

will stock internals hold up in the bottem end, head is pretty built with CTR cams, skunk 2 intake mani, jg valve springs and retainers, type r valves, ported, milled, and shaved head . i was looking at putting a t3 .60 trim on it and running 10 psi, 7-8 daily. any thoughts. motor was rebuilt and has new rings, i believe the rods and bearings where re-used. should i just save up and put 9:1 compression pistons in. if so what ones.


GSR turbo users please help out

a well tuned gs-r will handle alot more than what you're looking to toss at it.

Get a t3/t4, just a t3 will be way too small.

my gsr is on 8-10lbs on the regular and beaten on stock internals and 100,000 miles for about 6 months now im going to take it to 12-14 when i get my hands on a wideband again

Re: Boosting a GSR.
 

the head is built and ive talked with numerous people about it, they say that theres way to much compression and ill end up blowing it. i want to ru t3/t4 .60 trim turbo, should have been more specific in my first post.

Re: Boosting a GSR.
 

your head will be fine, thats not the problem. what IS, is your compression, its pry higher since your head is shaved as well. id be carefull, and get a really good tune

Re: Boosting a GSR.
 

If the compression scares you buy a Cometic headgasket as they make some nice thick ones to drop compression considerally.

Re: Boosting a GSR.
 

you really need to be more selective about the people you talk to.

Re: Boosting a GSR.
 

I'm guessing you probably have loads of overlap on your ctr cams. You can turbo anything and a good tune will help. But ultimately there are far better starting blocks then what you have currently.
