anyone running this set up? if you are tell how it runs and did it make a big differences?

 

My boy Alamar is running that setup and it runs strong as hell. He is giving type r's a bit of a hard time. I don't remember his email address, but his name is milanoredgsr. I personally think it's much stronger than the stock gsr internals because I have driven his car and I had my own gsr and I noticed the difference. I would recommend ctr pistons though, because that would have bigger gains and more noticeable gains.

damn i didn't know it helped that much! i got a 96 hatchy with a gsr lookin to do that set up

 

i've seen LS blocks with oversized CTR pistons with SkunkII stage 2 cams with fully built head put down 210 whp...

 

about the ctr piston dont you have to get different rods? looking to be street fast and i don't to get val. slapped you know. anyone knows the compression wit itr pistons in gsr???

That setup is supposed to be about 10.8:1 compression ratio, according to
http://www.c-speedracing.com/howto/c...c/compcalc.php.

 

SILINITY16, go back check your selections on c-speed.... the CTR pistonin an unmodded GSR engine will be a hair above 12:1 if not more in a GSR, and with GSR or ITR rods you do NOT need to mod the rods for CTR pistons.

thanks for the help..... just trying to run 13.5 on the 1/4 in my hatchy trying to do it the smart and cheap. 13.5 in the street thats koo wih me. i aint trying to spend thousands of dollars on a set up you know....

 

You could hit 13.5's in a civic with bolt ons.

 

Ok owen_the_soyboy, I was only giving him the numbers he asked for. Read the post just before the one I posted. He wanted the CR for a gsr with ITR pistons, not CTR pistons. I know the compression that the CTR pistons would yield, but that's not what he asked for. The CR for a gsr with ITR pistons is about 10.8:1, which is what he asked for.

 

I've heard USDM B16 pistons yield higher compression than ITR ones, is this true?

 

That is true. They yield about 11.3:1 CR.

 

Thanks for the link, that's useful to get general ideas

 

I'm running oversized ITR pistons in my LS block.

 

yea that link is pretty cool i raced a gsr yesterday my hommie i beat him by like 4 cars... first time running my car since i got it. just wanted to see if my car was running right well damn it's more then running right...

 

okay I see, just good practice to specify... like ITR or CTR ya know...

 

how much gain would you gain from the setup? horse powerwise...

 

I couldn't tell you that because I simply don't know. My friend didn't get his dynoed yet. Hopefully someone else has this setup and can post some numbers because I some would like to see what power gains were made.

 

a yoo if you had 1000 to spend on a motor what would you do to a gsr motor... that would make a big differnces..

 

compression should be around 11.1 to 11.5 (approx....depending on head work)...good for at least 170 whp with bolt ons....

 

I'm assuming that you already have I/H/E so I would go for some Skunk2 Stage 1 Cams and a pair of cam gears. Valve Train is not required to do this but is recommended but you will be spending more money. Nipponpower.com has this setup for pretty cheap. Just my opinion.

 

ok one quick question for someone....... i am ordering my ctr pistons soon, and on my motor im keeping the block the same size. when i order the pistons what size do i order them in?

 

nobody no that question

 

You won't know the answer until you crack open your block, to see if you can run STD or OS piston size.

 

ive already got the block cracked its a question to ask even if the motor was assembed.
