I was just wondering what pistons you guys are using in your setups?

I'm wondering because i can't find any ITR CP's in 84.5mm bore

 

I'm running Wiesco +2cc dome 85mm pistons.

are these the crv/vtec ones or are they b18c ones that they offer?

 

I am running this part number: K567M845
I am also running an 89mm crank instead of the stock 87mm

 

ooh ok, i'm using the stock 87mm crank, thats why i'm asking no one makes a itr piston in 84.5mm, only GSR's with wierd compression numbers

 

What kind of compression are u looking to get?

 

i was aiming around for 12.5-12.7, but i'll settle for something around 12.0-12.5.

i think i'll be going with the Arias 84.5mm 11.9cr GSR pistons. with those pistons i should be at 12.1 or something with my milled head

 

if a remember right... when my brother built the motor in my car he used 84 or 84.5mm CP pistons... it originally and rollerwaves till one of the rods snapped

so you were running endyn rollerwaves before and now you're running CP's?

if so, are you using the itr crank and itr zized rods?

 

I am running a 2L in my JDM Type R. But it has a B20B short block mated to an ITR head.. Probably not the info you are looking for.

 

ya... i was running endyn rollerwaves until a rod snapped... now using cp's w/ a jdm crank and im pretty sure stock stroke.. ill find out some more particulars... you prolly want to leave the stock stroke if you are using it as a daily driver.... the current set up netted 232 whp and 163ftlbs of torque

I'm running a b20z2 block with ITR crank and ITR rods....pretty close though

Yeah, thats what i'm doing right now, itr crank, itr sized rods. But going with B20/vtec CP pistons at 84.5mm gives me a lower cr than advertised

 

I'm gonna be running +2.5cc 85mm CP's, these are custom ordered through Rocket Motorsports.

 

we just built a 2.0 ITR motor useing CP pistons purchased through import parts.

 

is it safe to run 86mm bore for all motor setup ?

RLZ in Charlotte built my motor and called me a ***** for only going 85mm. They have built several 86mm daily driver n/a cars without any problems. I personally went 85mm.

 

whats the engine capacity if u run 86mm bore on b18c ??

2.1 ltr ?

With what stroke? Stock 87.2mm x 86mm gives you 2026cc

Use an LS crank and it bumps up to 2068cc

.....what Pondus said.

I'm surprised we don't have a "displacement calculator" available online like we do with the c/r calculator's available these days.....

 

-1cc custom weisco's
but i'm a 92mm crank and 85mm
and also RLZ built

 

84.5mm w/ +8.5cc

 

good god that's a dome!
