While cruising on the highway I down shifted and let loose! I redlined my supra and then shifted to fourth. About three seconds after shifting I noticed a puff of smoke come out of my exhaust, it only happens when I let loose, WOT, and it only happens about three seconds after I shift. It may of happened since I bought the car, 98TT 6speed, 8 months ago, but never noticed until this weekend. What causes this and is this normal?
I have a BPU++, FMIC and AFC and HKS SS BOV!

It's carbon. Everyones does that, not just Supras.

The smoke is whitish and if it was carbon wouldn't the smoke be more black?? Just wondering b/c it seems like too much!

I think white smoke means something with turbo seals going bad.

Is it a fix or a rebuild?

Rebuild.


Or else it could be valve seals. But I believe valve seals only gives the smoke upon startup. Your car is a 98 correct? I'd ask someone more knowledgeable on this board, certainly isn't me.

Yes it is a 98! What valve seals?
