The turbo MK1 is up and running, all parts from a local junkyard. Makes good power up to about 5300 RPM, then drops off, will look into it. Have insalled a diy water injection on it to stop detonation. Anyone know how much water I should inject?, running standard engine with 9 psi of boost and a home made A/F meter, intercooler from a Saab 900. Its good fun to drive, prob as quick as a nos system (when sorted) without the re- fill probs, Steve.
