I am considering going single, but need more info. I have a downpipe, exhaust, turbo timer, fuzzy boost control(which can be sent up to 25psi) . I am thinking about the T88, but want to know what else I need and the cost of the parts. like VPC. and will fuzzy boost gauge I have work? An turbo I looked at that was resonably priced was at directed Engineering. anyone have any experince with these turbos? Also what is the spool up on both. With this much power will I need bigger wheels/tires?
