Re: "Compound boost"?
i hate rearmounts too friggin laggy coming onto boost and the response is shithouse.
good for drag cars maybe but shit for anything else.
had a mate with rear mounts to get better weight distribution, we ended up canning it because you had to be on the go pedal about mid-corner/pre apex to have the turbos spooled for corner exit, switched back to standard mount with water to air cooler, boom, insta spool was back.
exhaust gasses slow too much by the time they're at the rear of the car.
as for repairing a turbo, if the housing isn't damaged i always just throw a new balanced cartridge in and put it together, not a hard process.
