Will a supra twin turbo upgrade fit the Is 300, i was told that it will but i wanna make sure, if anyone knows who makes a good twin turbo setup post links or info.

There are a couple of guys on the forum who have supra engines in the IS, but as for whether or not they are the twin turbo I'm afraid I can't say...

Try Ray Hall's website in Australia.
He has the 2JZGTE in an IS200.

There are problems fitting the back turbo around the clutch master cylinder. You will notice his latest version of his motor has been upgraded to a single turbo.

I have the single turbo 1JZGTE VVTi in my IS200 and there was no problems with clearance anywhere.

thnx guys, i thought i was being shut outta the forum cuz my posts kept on dissapearing, but they were being moved here, thanx for the help, i think imma go single turbo, or maybe supercharge, what do you guys think is better, which will give me more power, i kno teh sc is from teh pulleys so its rite off the line but i ned to kno personal opinions

The (TTE) supercharger is only for the 200, so you'd have to go with a turbo, unless you know of one from another brand

Try here loads of 300 SCs

2... Both from PLP and 1's only for the 2001-2002 so you've actually only got 2 choices if it's from those years, not actually loads is it

Check out the sponsers link at the top of the page, visit TDI tuning they do a supra twin turbo conversion for the is200/300 and reckon if needed they will get your motor to kick out over 700bhp.
