i have a 92 integra rs, and i am getting a b18c1 engine for it. now ppl are telling me to go with b16 piston to up the compression to like 13:1. is this true??

 

Not 13:1 but it will bump your compression up to about 10.3/4/5 over the stock 10:1

 

it's not even worth it if you ask me. that .1-.3 compression isn't worth the hassel. if you're gonna do it...might as well use ITR or CTR pistons and get it up to the 11's.

 

it will help a lot
all you guys are wrong it will bump cr almost 1 full point
gsr pistons have no dome
you will go from 10.1 to 11.3
10+hp and now you can run biggger cams too

wtf are you ppl talking about bumping it only .3
dont post false info

and ctr pistons suk for the street
too high cr for pump gas
pr3 pistions are the way to go when your on a buget. bigger dome then usdm itr pistons too

 

thanks guys.

 

also look at the JDM civic si B16a2 P30 pistons, they are alittle better then the pr3 usdm b16 pistons

what the hell are you trying to say
you now that p30 are 10.4 in a b16 but when in a gsr with the longer stroke that will make about 11.5 compression

 

If it is 10.4 in a b16 then its about 10.9 tops in a gs-r. It's a very simple mathematic equation. Bore is the same. Stroke is a little longer and cylinder head cc is about .9 less.

 

ITR pistons- bump up to 11.1:1
CTR pistons- bump up to 12.5:1

Lots of people run CTR pistons in a street car, including myself. I would hardly say they suck for the street. Have you ever driven a car with CTR pistons?

higher compression isn't necessarilly a good thing if you're even considering turbo, but you probably already knew that just like eveyone here

 

ok me and my friends have been talking it over and we're wonder how you fit a 1.6 liter piton into a 1.8 head??

 

go with the CTRs if 93 Octane is available in your area.

I ran them perfectly fine in my GSR for a , while. If you are that scared about the compression being too high, you can get a custom headgasket from cosmetic to give you a little more room to play. However the compression with CTR pistons in a bone stock GSR motor with OE everything yeilds more than 12.5 : 1. It's more along the lines of 12.8 - 13:1. The c-speed compression calculator does not fully calculate the entire dome area of the piston. You'll have to cc' the actual piston yourself once you install them to get an actual reading of your compression.

Check my project log in my sig. My CTR piston install is there.
