the throttle body bolts straight on if iirc but may need a bit of fetling for the throttle cable mount, tbh it may add a few bhp and make throttle response that bit better but not a whole lot. depending on budget have you thought about bike carbs? throttle bodies? 40's etc? Not as expensive as the turbo route and can get a good amount of power out zetec.
I owned a escort si same bhp engine standard as gti, had a powerflow stainless system, decat, chip, air filter and boost valve, my mates rs2000 couldnt look at it.
Hmmm your mates RS2000 must have been knackered if it couldn't keep up with a GTi with those mods. Or are you talking about a Mk1 RS2000?
You can't just bung a bigger MAF on with the original ECU and expect it to run right. The MAF and ECU are calibrated to work together and changing the MAF will throw the calibration right out unless you have a custom map. The fuel consumption would go through the roof which is no good if you're on a tight budget.
