Andrew,
I am planning to go with an aftermarket ECU, intercooler etc.I'm hoping to
be able to get, say 260-280 bhp eventually. The plan is to sort out the
right turbo now to go with the planned modifications. That's why I thought
it best to ask as I didn't want to waste money on rebuilding this turbo if
I'd be better of with another type in the long run. That looks the case
here.What would have a T4 from the factory then or is it a mostly
aftermarket unit?
Thanks for the advise,
Eddie
