hey folks,

been browsin the boards lookin to see if anyone else has taken this engine to a sort of extreme...basically, it's a daily driver that I am lookin to turn out some rather serious numbers. Off-season now here and I got the car out in the garage ready to go...just a few minor issues...

Has anyone gotten a FIRM answer as far as proper piston sizing and specifications go for the d15b? I spoke with a rep at JE and he just sorta hummed and ha'd on the phone with me as he wasn't sure whether to go d15b7 or d16z6 and what the maximum size recomended would be (few guys I know went with a 77mm bore on a d16z6 but again even they looked puzzled about most of the questions...).

That just seems to be the ONE thing stumping me with the piston/rod combo as far as this engine goes...turbo's in the garage...fmic chosen...all the fuel stuff and ignition is ready to go...so if anyone has done this successfully and can lend me a hand here that'd be awesome...

 

IM turbodcx...he has a fully built d15b...

 

cheers man, thanks
