Default which engine is better for a turbo set up in a civic?

I want to swap a B18 into my EG civic but I' mnot sure if I should get the B18B or B18C, I've read that the B18B works better for turbo set ups since the compression ratio is lower than the B18Cs, but I also want vtec, would a ls/vtec set up work with a turbo? I'm planing to get stronger internals so I can run at higher boost, but I'm not sure what engine to get, does anyone know which engine would do better under boost?

B18b = non vtec
B18c = vtec

vtec - more power
nonvtec - cheaper

b18c1 comes with a main stud girdle stock, oil sprayers and vtec. The ls has no stud girdle or oil jets spraying on the back of the pistons or vtec. I would go with the b18c1 just get lower compression positions.

I cant remember one engine has a longer stroke and one bigger pistons??? One will produce more tork???

piston size is the same. the ls has an 89mm stroke as opposed to the gsr's 87.2mm.

No.....there is no reason for him to get lower compression pistons on a b18c1...the motor will make plenty of power and be reliable(with a good tune) as it is

Very true, Didn't know how much boost he would run just said high that means 20 or so to me? How much with stock pistons? 16?
