As the title says, what is a bone stock B18C6 capable of handling when turbo'd running 98 octane gas?

 

whats a b18c6 ive never heard of it.....

 

It's an EDM ITR engine.

 

take this as just a suggestion and just my opinion but this is what Ive seen and know. Im going to assume its built the same as a JDM or USDM motor. The sleeves are said to be good to around 15psi BUT Ive seen them go at lesser boost and Ive seen 18psi on a stock motor. ALso, the ring lands (probably the weakest part of the piston) are prone to giving out and you may have issues with those. Realistically unless your car is tuned to perfection, I wouldnt risk anything over 13psi on a stock motor.
