Z20LET into Mk3 Astra - Throttle

[jimbo87]

Looking at doing a Z20LET conversion into my phase 2 GSi. I want to use mk4Astra zlet ecu & loom to keep costs down, I know the throttle is different on a mk3 to mk4, but was wondering could I use the inlet set up etc from an XEV on a ZLET to convert it? I know basically they are similar engines, would it work?

If you're using the Mk4 dash loom as well, you could plug in the Mk4 pedal and use it as per a factory mk4 astra

You might need the transponder and clocks as well so it makes sense

Dont forget coolant module thing too

I'd be using the dash loom as far as the clocks, as converting to mk4 clocks anyway, and would need the ecu for the speed signal from the ABS sensor. So the mk4 pedal would fit? if so that's the solution to the problem thanks mate.

Not sure if it would fit directly but I imagine it would be much less work than some other solutions.

Speed signal doesn't come directly from wheel ABS sensor as per older Vauxhalls, it's something to do with the ABS module under the bonnet! I noticed this recently on a friends Z20LET conversion

The one or two mk3 boys are currently doing the dash clocks conversion, think it requires an amplifier
