what pistons?

 

ill rephrase it better, what is the weak point of the f20b?

 

i have never heard ringlands crack off on a f20b, im not all that familiar with that motor as i never owned one nor know many people with one so in not going to be able to be of much help. But F series are known to be pretty bulletproof no matter what.

 

Alright well you didn't really have to be rude about it in the first post...I've just heard that when going all motor on composite sleeves you need to resleeve with iron so I just assumed boost would be a horrible idea on them. Didn't really take s2000 sleeves into consideration though.

 

i think when im done boosting this motor i will write down everything ive found out, as the info is nowhere to be found. ive beat the hell out of mine n/a and blew it, and now im gonna do it boosted.

 

the weak point in a h22 has nothing to do with the strength of the cylinder wall, it has to do with weak ring lands on the pistons. and Frm is not compatible with forged pistons. so if you could run a forged piston in a closed deck h22a1 or h22a the power that it could take would be huge.

 

also the f20b motor is a expensive motor to build the rods are about 1000 and the pistons are 900. and you could bet the motor would be good for roughly 500hp. cp has pistons and carillo has rods for it. you have to call them and explain to them that they have made parts for this motor, even if they knew it or not. so they can make the parts but they are not off the shelf so they cost more. and you can use a stock f20b head gasket and arp h22 head studs.

 

the pistons are factory forged.

 

no they are not, the f20c factory pistons are forged!

 

are you positive? to my understanding most of the factory internals are forged. please provide your source also.
