I have a Mk 3 Astra GSi, the 1.8 16v Ecotec engine. I need more power! I have thought about a turbo engine, but think a 2L red top engine might be better. Has anyone done this kind of swap, and how much did it cost, inc engine (any one want to come and do it for me!! for free!!). I know I could get NOS, but its too expensive to keep filling up, and I`m not sure of the reliability of the turbo. Please help! Anyone think this is pointless, any views welcome!
