Im fitting a Garrett T3 Turbo to my Astra GTE 16v...i have ripped the engine appart and have checked the head, block and crank and all look super. im getting some low compresion pistons from courteny (any one know the spec on them). i need some help in the plumbing area...it looks like my turbo has oil in/out and water in/out i had no fitting instructions with it so if any one has a copy i will have your children. also should i run it at about 6psi first and see what i can get up to..???
i have photos but can't post them, can email if it helps.
