I know there are plenty of searches i can do, kinda did(not lying) Some say that s14 blacktop R's didnt come with BB turbos, but when I installed my intake, I spun the fins in the turbo with my fingers and they kept on spinning, Now my question is did SOME come with BB turbos, cause the way it kept spinning lead me to believe i have a BB t-25 stock turbo. i barely spun it and it kept spinning(the fins that is)...ANy stupid comments welcome, but answer the question. Thnak you I ordered my front clip from Japan, and it was in great shape, installed the intake, spun the fins and wow i immediatly thought it was BB. when I drove it, (without a boost gauge, turbo started spoolin at 2500rpms...and when i left off at 6500, i could heard a whisling sound....which leads me to believe it is BB. I might be wrong, I might be right. Just a thought. and alittle answer might help. Thank you FLAMERS WELCOME

 

yes, they are bb
whats a blacktop R? was that supposed to be SR? lol

 

SR sorry, so it is BB? thank you for the quick asnwer, now how muchh Hp could this stock turbo hold probably around 300-350 effientally?...(although im getthing the HKS GT2530, or the all mighty T04Z HK turbine kit soon.)

 

More like ~280whp @ 16-17lbs.

 

S14 = BB

S13 = CB

 

With stock injectors yeah even 280 is pushing it but, Got a buddy that just dynoed 321hp @ 1.2 bar on a S14 T28 with just 550cc inj, 256 pon-cams and a SAFC with manual boost controller. My old set up with an s15 turbo 550cc's 264 cams manual boost controller I pushed out 320whp with a power FC tune @ 1.3 bar
