This is not for me but for jtmikey.
He is after a astra gsi/turbo and isnt having alot of luck, but he has found one that has had conversion, BUT, it is running 6 injectors, and does not have a LET ecu or loom, so im guessing that it is running on XE ecu with a second injector ecu type thing, i would guess.
But also how would boost be controlled as it wouldnt have an amal valve, bleed valve?
so how would the ecu know waht to do if its not designed to run a turbo?
Just dont want him to get a car that will go bang after 6 months, and ill give you 3 guess's who done the conversion, but the first 2 dont count
