pistons / rods... should it be bored / honed .. or you using factory bore ? what is the factory bore for b16a ?
whats a good compression goal since it is going to be a turbo setup ? and how should i go about getting there? ... thanks for the help / advice by the way
1) rods - you can't go wrong with Crower econo billets or eagle H-beams, they are both good. If you are gonna be going really big later on, maybe invest in some cunningham rods
2) pistons - CP is IMO the best piston out there, customer service is top notch. Wiseco and Arias are also great brands.
3) compression - If you want a responsive engine off boost and are only looking for around 300 whp, I'd say probably closer 10:1 compression is what you'd want, but if you are just looking for good on boost performance and are shooting for bigger numbers, around 9:1 is a better place to be. Just get pistons that will get you the compression you want. No need to mill the head or get a thinner head gasket, but those options are always available.
4)If you are not going to sleeve the motor, then stay with the stock bore, as this will give you the strongest cylinder wall to work with, and that is what you want in a boosted engine. If you sleeve the motor, I'd go with 84mm bore (stock is 81), as there is a large aftermarket piston support for that size. That will increase your b16's displacement to a bit over 1.7 liters, and will give you a bit more torque and room for growth.
Just my .02
FWIW, my b16 build to come will consist of cunningham rods, cp pistons, 10:1 compression, AEBS closed deck sleeves, 84mm bore.
