i understand there low compression, so what would be the best pistons to put in to get the best power increase? i was thinking some b18c1 pistons..?

 

If you are going for higher compression you would need something like ITR or CTR pistons. GSR pistons won't do much for you depending on what block/head combo you are running.

 

I got b17 block/head, but someone said the b17 is a different size than a b18 or b16 and i dont want the piston to come up and hit my valves.. or do you think itr or ctr pistons would be fine?

 

How are you making 200 hp in the B17?
The bore is the same as the other B16, and B18 engines as far as I know, so the pistons will work. You should have valve clearance, but there is a site that will help you...Let me see if I can find it.

 

The bore for all B series is 81mm not including the B20 which is 84mm. I would go with the CTRs.

 

cams, cam gears and gsxr1000 itbs and bisimoto headers and b17a1 puts out 160 stock so my best guess is 200, and thanks man i dont wanna start that thing up and hear a bang haha

 

The CTR has the most dome out of all the B series pistons...

 

Is it tuned or anything?

 

i think im gonna have to go ctr, thanks man its bin bugging me for a couple days now and if you're talking dyno tuned.. nah havent gotten that far yet but i just pulled the engine out last night cuss im gonna get all new internals, slowly but surely lol
