would jdm itr pistons work on a other wise stock motor. i gotta bore out my block do to a bad spark plug.. and im wondering if i can use jdm itr's pistons on my stock crank and rods.. let me know!!

 

bore out your block because of a bad plug? how does that happen?


to answer your question, yes you can. but the pistons must match the bore size too.

 

...electrode fell in my cylnider and fuckd the side walls and my pistons... i guess i advanced my timing to much or some bs...

 

what well b the result of putting jdm itr pistons ... higher comp i know.. will my tq get higher?? mid range or high? any help would be nice...

 

B16 pistons would yield more compression.

 

i drive this car dialy... b16 to high..

 

p30's would only put you at 11.5:1. pr3's slightly lower. that's very doable on pump gas with a good tune.

 

well. im hoping to just get alittle more top range w/ the pistons ... and i wanna raise my red line to 8500. w/ stock valvetrain w/ arp rod bolts... which is achievable?

 

if ur boring your motor ull need over size pistons. bore it .020 and get 81.5mm pistons in what ever comp ratio u want

you need a better valvetrain and better cams

 

u dont recommand getting JDM itr pistons Os...? im a oem fan thats all...

 

if you're not looking for crazy power and the itr's will put you in the c/r range you want get them

 

can u see teh maarks.. couldnt get a good enough pic of the side walls...

 

clean some of that carbon buildup off

 

or itr pistons. hehe

 

p30's

you wont see much of a difference in tq with the jdm itr pistons

sucks about the whole spark plug stuff

 

w/ p30's OS what would i have to do put them on my gsr.. ??? im not to smart w/ this honda stuff.. i work on big rigs.. lol

 

with os pistons take them to the machine shop so they know how big to overbore the cylinders

 

get the p30s or pr3 and get a better valvetrain if you planning on revving to 8500

Dont do that ^^^ A .020 bore is for 81.25mm pistons and go with the JDM ITR's, you will be surprised of the c.r. and the CTR are too high

 

pr3's, itr's are overrated

 

with pr3's... what do i get it bored out to???

Mindless was right.

1"=25.4mm so .010"=.254mm, .020"=.508mm

It depends on what size piston you buy.

I would take that block to a machine shop first and let them measure how deep the scratches are in the bore. That will determine what size pistons you need.

 

OK.. Thank you so much for your help guys. i think im just gunna go w/ the ITR pistons.. now i found blox A cams.. u think those would mate together good or bc 3??
