Postby XR2iT on Wed Jun 04, 2003 7:10 pm

I have a S2 ERST engine and turbo in my Mk3 fiesta. i have done some tunung and as a next step I was wondering about upgrading the injectors. Anyone got any helpful advice for me?

Fit like...........

If you are using the complete S2 engine, then there are NO injectors. The S2 engine uses mechanical injection, so im afraid to say you can be limited to fuelling, but then again i know some tuners have ways of changing that.
5th injectors can be VERY dodgy!

i had heard that you need to get a 5th injector to get serious horsepower but since i have a restrictor on the turbo I wondered if it was worthwhile. So what do you mean by dodgy?

5th injectors can be a waste of time and not really work well. I would push up the boost and see how much the fuelling can take on a rolling road. Then you know your limits but........
I know AVA in Glasgow have been pushing the boundries of the MFi, but i doubt they will give away any secrets ;)

My car has been to both RJM and Falkland as they are quite close to where I keep the car. I have just rebuilt it after a long period of sitting about and I need more power to compete with the 6R4s and Scoobies!

Well I have been putting the engine back in this last week and I have been wiring it up tonight. With a bit of luck I will get it figured out and running in the next couple of weeks. Assuming I have put everything back in the right place:D
Once that is done I will give these guys a call. I should say that I need people who explain what they do to the car. There is no point in getting things done to the car that I don't understand because if it breaks during a rally and I have no idea what has been done I'm stuffed. Since I am no mechanical genius this limits it a bit!

If you explain that to AVA they will keep you informed.
