Fuel Injector Upgrade On Mkiv Supra

[supra TT myster]

Hi

If i have a standard MKIV Twin turbo supra, i was just wondering what size fuel injectors i can go up to for more power?, or do i have to upgrade other parts first before doing this?

Thanks

Jap spec or UK spec ??

As the Jap spec runs smaller injectors than the UK spec, but before you get that far, you really want to BPU it, exhaust, induction and raise the boost.

Hi

Its a Jap spec one, if i get a boost controller what is a safe level to go? 1 bar or 1.2 bar?

What does bpu mean??

BPU is Basic Performace Upgrade, exhaust, induction and raised boost.

To be honest you best of looking on www.mkivsupra.net/bbs which is the UK MKIV owners group.
