Its actually boost cut at like 4.9 volts IIRC, as it will give you hell if you try to max the sensor out. I recall seeing that done, google it. I won't argue that a TD can be cheaply, its just that they aren't exactly auto-x chassis's, and most of the parts have 2x the ideal milage, and are older than most modded Hondas.

IMO it would be more fun to get a colt/mirrage, DSM awd drivetrain, and make it work. They offered some from the factory that way...

BTW I have the Road & Track issue from like '88 where they tested these sorts of cars. The only non-turbo was the 89 Integra - and was just faster than some of the turbo cars (just 0.1sec slower than the TD, IIRC).
