anyone?

 

all besres have a 81mm bore except for the b20 which has a 84mm bore.
and yes itr pistons fit in your car but i would much rather you get b16 pistons

 

why B16????

 

im curious as well..why b16?

 

b16 have a higher dome, thus a higher compression ratio.

because
usdm itr pistons in a gsr = 10.8 CR
jdm itr =11.1
b16a pr3 pistons = 11.3xx

and ctr's suck and only should be used if u want problems or if you run race gas

Be a man and go with CTR pistons you will never know what hit you!! hahaha

 

yes the standard 81mm bore will fit in ur gsr block...

but go with jdm itr pistons... theyll yield about 11.1:1 CR, which is higher than the usdm ones.

 

Go with JDM ITR's, the R series had the skirts coated with molybdneuim (sp) which made them more slippery. Less power lost to pushing the piston, more power to the ground.

CTR's are just asking for trouble with the high CR.

 

Will compression from b16 pr3's be safe for daily driving? Thanks!

 

stealin ur post here mike but, if i was gonna do a first gen b16 in a crx and wanted a gsr block..would it be better to use the b16 pistons in the gsr block since id already have em?

 

To answer the original question: yes they will fit. The JDM ITR pistons will work fine, as will the B16 PR3's or even the P30's. Assuming you get some mild tuning, you shouldn't have any issues whatsoever running on pump gas with any of these.

 

I would get JDM ITRs over B16As because of the teflons on the skirts. I would not go with the JDM CTRs because compression is too high for street use. BTW, the JDM ITRs yield closer to a 11.2-11.3 CR in a gsr.

If you run a vafc you can tune it good enough to run ctr pistons. Those would be my choice. Well, my choice would be 9:1 wiseco pistons and boost but.... for factory pistons then ctr all the way.

Funny because Im going to be running hondata(which is superior to a vafc) and Im not going to run CTRs in my car...ofcourse I dont do things that are "good enough" to my car either.

 

would the type R piston work with a 82mm bore on a GSR?

 

^ no it wont.. you'll have to buy the piston oversized

offtopic: I have some USDM ITR pistons for sale.
