Will TT Supra pistons work in d15b7 with a stock size connecting rod? I know they fit in a d16 with a b16 rod combo but nobody says how to modify or if they even need mods. I know that a lot of people like vitara but isn't the comp ratio like 8:1 in a d15. What is the comp ratio of a supra piston. Just looking at my options. any info is appreciated.

Thanks for the link that answers the comp ratio but what will have to be done to fit a TT supra piston in a d15 with the stock crank.

 

Dseries bore is 75mm. 2jz/1jz/3sgte bore is 86mm. So unless your gonna bore you D 10mm over, it aint gonna work.

 

do you think it will make the cyl. wall too thin

 

should be just right with some devcon

 

just fill your block completely with devcon.

then just cut new bores in the ----.

bam

goood for 800psi.

 

thats a 55:1 CR

be the First to turn your sohc into a diesel

 

Nevermind... 1G-GTE pistons are 75mm. Good luck with that. Vitaras or bust.

 

yup old school supra is 75 mm, and in a 1.6 block, with 137mm b16 rods and notch the block and have a machine shop fit the pistons on. block post the sides. your good to go
