I am looking for forged pistons for my turbo build on my b17. I was looking at either CP or JE pistons but have a hard time finding ones for the b17. Will b16 pistons work on the b17 since they are the same bore, because I was thinking of getting b16 forged pistons with cr of 10:1, which will give me a cr of 9.5:1 on the b17. Also is 9.5:1 too high for a daily driver boosting 10lb on a t3/t4. Thanks
Anybody have any ideas? Any help will be appreciated.
yes
yeah the pistons are the same. you will have to have it tuned properly to run 10 lbs on that but it can easily be done. Do you have rods to go with that or are you just going with pistons. I have an ls/vtec turbo with 9:1 comp and it drives fine and make 320hp and 11:1 afr at 10 lbs and is not breaking a sweat. Your b17 can do this but with a slightly higher compression ratio you won’t feel as much lag before the spool. Hope this helps
thanks for the reply. Im actually rebuilding my engine with new crower rods and forged pistons and minor head work. I want to get a compression ratio between 9:1 and 9.5:1.
