All the internals are swappable between the IS200 and Altezza's, just the mounts that connect the drive shafts are different - they are easy to swap though, and the Altezza drive shafts are interchangeable also.

Why would you want to put in a different diff ratio ? Putting a lower one in will slow down your acceleration but increase your top speed. It will make you do less revs at an equivalent speed, but then the IS200 isn't exactly noisy anyway ?

IS200 Turbo project now just about complete ! See my thread here and leave your comments.
Now running standalone Syvecs ECU and no stock ECU !

16-04-2017, 07:55 AM #16The IS300 ones are bigger IIRC and don't physically fit, the drive shafts are different, the ratios are wrong, I also think the bolt pattern for the prop is different - although that is a guess from something I heard Wayne (Supratruck) chatting about.
