Toyota Supra Mk4 turbo problem

Jan 05, 2004 2 Replies

I am from the UK and have a '93 (MK4) Supra turbo auto Jap import (forgive me for the auto ;-)



I *think* I may have a problem, but would really appreciate some input because I haven't had the car that long.



The problem is: sometimes when I kickdown from 3rd to 2nd (and occasionally from 2nd to 1st) the second turbo won't kick in until the next gear shift (e.g. going from 3 - 2, the 2nd turbo doesn't open up 'til the box shifts me back into 3rd after hitting the redline).



This only seems to happen when I kick down and the revs are above the



4000 where the 2nd turbo opens. If I kickdown and the resultant revs are, say, 3500, the turbo will open up fine.

Other than this, the car runs absolutely fine.



Any help would be great, there aren't many mechanics around who genuinely know what they are talking about - as I am sure Supra owners out there will appreciate!
