Hey guys I am doing a 5sfe turbo project just for fun not lots of power. Now obviously the 5sfe ECU will not push enough fuel to feed turbo support. I was wondering, considering I am using a t26 turbo from a mr2 with aftermarket upgrades to support the turbo application would I be able to use a fuel rail with injectors and and ECU from a 3sgte to support my needs.

you cant use a 3S-GTE ECU. the distributor is different and sends different signals. and you cant just use the 3S-GTE distributor either. It will not fit in the 5S-FE head.

I still have the turbo kit I built for sale. It comes with everything you need. search in the for sale section.

Like Smaay said, you can't use a 3sgte ecu.

if you look at some of the sticky posts on here, you will see a combination of map sensors, injectors and safc that can be used. This works, but leaves you with very high levels of ignition timing under boost, which will lead to a blown motor. Best thing to do is to build a cheap stand alone ecu like megasquirt so that you can control fuel and timing.

Doesn't have to be a standalone. A good Piggy-back works as well. They can retard the timing too. For example a Greddy eManage Ultimate. But in the end it's not gonna be cheaper than megasquirt I suppose.
