This the start of a one month project. Because of uk rally rules I need to put a 3sge engine into my st185. The plan is to put a engine out of a st202 a gearbox out of a rav4 and if the budget allows a motec ecu. What you all think.

Not sure what itbs are but if you mean throttles bodies then no it has to be on the original injection.

3SG is capable of some good power. But with the stock injection I'd guess you wouldn't find more than 5% in power from the ECU itself.

What the hell kind of class do you have to run it? Why not just run in a class that allows 2.0T?

Uk night rally rules. No turbos only aloud start injection etc.

If you want the full on rediculousness of the 3sge, then get a blacktop beams, but be sure to install the redtop oil pan, and pickups as the BT is designed for longitudinal mount. Then just bolt it to the stock transmission.

Quick update on the car. Engine and box are out and a 2002 rav4 is been ordered. The brakes have been measured and removed and a set of fait 4 pot brembos st205 rear Calipers and some Subaru disc are also on order. This is to run 15" wheels on gravel. The st202 is going to the dyno before the engine comes out as there's mo 4 wheel dyno close. Will add more info as it gets done.
