I had a question about boring my sleeves out to accpet JE's 81.5 mm pistons. In my helms manual it says that service limit for a B18C1 cylinder bore is 81.25-81.27 mm, would boring my cylinders out past Honda's max. bore size to accept JE's pistons severly compromise my engine's life? I can't afford to re-sleeve my engine or else I would. I'm just looking to add JE pistons and Eagle rods and run about 15-18 psi of boost. I'd really appreciate your input. Thanks.

 

lmao

 

I am pretty sure you will be OK. But you are speaking of SRP's, because with a JE you could order exactly what size you need.
