I have a BONE stock b16a, the rings are starting to go out so I'm thinking of just tearing down the block and making an improvement can I use 81.5mm Nippon b16b pistons and have the cylinders bored to fit the pistons?

Looking to build a streetable motor, raising a bit of compression, and i'm reusing my stock rods.

 

Can it be done? Yes

 

What sort of things do you guys recommend me doing during the rebuild, it just needs rings, but I want to make more power so what sort of things can I do while the block is apart.
I want to make at least 170 to the wheel.

 

might as well replace all seals and bearings while it's apart

 

arp rod bolts

 

yeah i'm going to do all the seals and bearings, but i already replaced those 9k miles ago I just had the motor rebuilt it's just I did the swap wrong and wired the resistor box and my injectors dumped a lot of fuel and f'd up my rings.

 

9k miles on bearings? There prolly fine. But I would make that judgment call when u see them. Other things to think about changing while your down there. Water pump. Oil pump. Timing belt. Arp head studs. Rod bolts if you think its necessary. Other than that. All the power is made in the head.

 

okay, great thanks where can I find arp head studs for a good price? Would I be sacrificing anything using 81.5mm pistons I heard it's not safe to rev high with heavier pistons.

 

CTR pistons are already heavy, if your using them the extra .5mm isn't going to make any difference. The ship has sailed on that domain so to speak.
