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

Re: Boosting a GSR.
 

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

Re: Boosting a GSR.
 

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

Hotrex can help you out.











Where is he? :S

Re: Boosting a GSR.
 

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.

Re: Boosting a GSR.
 

the head has been shaved down alot. I have never seen one that the deck surface was so close to the valves. I don't know if there is a way to messure how much the head has been shaved but a cometic head gasket would be the best way to go.

my 99 GSR is taking 9psi daily and i plan on running the same setup on 12psi next year....that's all on the stock engine too.

275/194 @ 9psi

T3T4E 60 trim

Re: Boosting a GSR.
 

A good pick for that setup is the stage 1 t3/t04e 0.63/0.70 46 trim. You could also go stage2 or 3 0.48 a/r turbine for an earlier, yet more gradual spoolup but that's gonna be more expensive.

I've heard of gsr bottom ends bein abe to hold 400+ hp... :o

Re: Boosting a GSR.
 

tuning the engine will be the key...

Re: Boosting a GSR.
 

Far better blocks? The B18c1/5 block is probably the best all around block honda ever made, it's got torque and revs high. Also his CTR cams are probably the best option for a turbo b-series there is, get some adjustable cam gears and your fine with the head.

Re: Boosting a GSR.
 

Exactly, get some cam gears and do some dyno tuning, once you get it tuned for 8 psi, do a little cam tuning.
If the head is shaved a considerable amount do like previously mentioned and get a cometic head gasket to bump down the compression. GSR's love boost, if properly tuned it will handle well over 8psi...

Re: Boosting a GSR.
 

Starting blocks, the ------- things you use while running. That thing you do with your legs, oh wait, your an american.

Running, its like walking moving without a car....

Point is, this guy could part out his tuned N/A motor and get a stock shitter motor with boost. And if he's clever, have some spare change for bling (pistons, rods etc.)

Re: Boosting a GSR.
 

That's a retarded idea, why part it out? Turbo motors need built heads too if you plan on reving high. His head will be perfect for turbo, just get some forged 9:1 pistons and rods and your set for as much boost as you want.

:y

i am sofa king we todd it

Re: Boosting a GSR.
 

Well, if anybody has any doubts about how solid gsr bottom ends are, check out this sweet video. I'm not saying it'd be super reliable (the one in the video) but it works!

Yeah that'S a nice race!

MAn that diesel truck is stupid fast ?!?!? :o

Re: Boosting a GSR.
 

i figured taking the head to a machine shop and measuring how much it was shaved and getting a cometic headgasket fit for that and run eagle rods and 9:1 pistons. plan on 10psi daily and 15 on the strips. but thats with a good tune. this is all gathering info and seeing if its really worth.
