I have a b18b block and b16 head....buying pistons and rods for it but not sure exactly what i can buy?
Will CTR pistons work and buying rods I have no clue?

 

get some strong rods. and as far as pistons. u want turbo.... get like 9:1 comp pistons. i personally dont know the ctr comp ratio but if they have a pretty low get them. good luck im doing the same thing as u.

ctr pistons have like 11:1 comp i think way to high for turbo

 

putting ctr pistons in a crvtec is defeating the entire purpose

 

turboing any stock honda pistons is not a good idea, even TYPE R yo, they are weak. just spend the money on some like wiseco 9:1 or JE or something.

 

so making 500whp on a stock b18 is weak??? and compresion has nothing to do with it... it just means more power at a lower psi..

WTF

most honda pistons come from the factory forged

OEM pistons are strong as hell

where are you getting this info from?

it also means detonation is more likey which leads to the death of the motor

 

So how long did your b18 last? 500 hp would take at least 25 psi. The ringlands on the pistons wouldn't last long at all at 25psi. Maybe a dyno run or two. Do you read D-Sport? They made a lot of power on a stock B16 but it didn't last long even on A LOT of tuning. And as for the C/R it doens't matter. There is a guy on here running like 11.5:1 CR and he is boosted. Lower CR just makes it safer. The higher it is the more tuning you have to do and constantly keep an eye on your AFR especially if you change elevation a lot.

 

okay don't make me get courtney... hahaha..
do you read modified mag? white gsr that resides in utah stock moter girl driver by the name of mia??? it ran about 40 passes, daily driven, daily abused, o and 150k on the clock?... o and 515 on 15psi...

 

as far as the compression goes... okay think any math or physics guy back me up.
okay nomal vac is -14.3.. or so psi.. "atmis. pressure". when you boost a engine you are increasing this pressure, now depending on displacement the amount of volume of air will change to reach boost. so fo an example you take a b18b, about 9.6-1 comp.."just a gues" now you start forcing air into this area lets say your running a small turbo, 18g.. and boosting lets say 8 gauge pounds. at this point your turbo is at the max only going to flow 400cfm wich works out to be about 27-32 lbs/min.. any way you take that area and decrease it i.e increase compression. you have now made this area smaller and the amount a volume has dropped to fill this space i.e less boost.. atmis. pressure stays the same no matter how big small your engine is, but when making power it comes to volume not psi, you have a smaller space it takes less volume, you increase this space you need more volume...
plain and simple

 

o the gsr still runs.. i didn't clearify that..
