Problem with your turbo charger?

Right, Bruce...I seem to remember the name Reeves on this unit, but could be
mistaken.

On this particular pickup, they started out on the high side of 200 hp, and
ended up with about 140-160 hp gain.
Again, allow for my memory lapses....

I believe the ECM was reprogrammed at the same time to make everything work
right.-

Actually, it was Squires, not Reeves...

I would not take advice from the person who said this. Engines are different
enough that you can't make that kind of generlization. 13-14 psi is pretty
high. There is a reason manufacturers change so many parts in an engine
when they add a turbo to it.

Very, very true. some engines handle it just fine. Some will grenade
over 7 PSI or so. If you can't find any data from someone who's already
modded your particular engine, doing your own research can be expensive.

A friend bought a Supra (2JZ-GTE) where the wastegate had
been welded shut. The boost gauge went up to 28PSI when he
put his foot down.

Ayup, there are a few engines that will tolerate massive boost and the
Supra seems to be one of them. Would like to have one some day but
their popularity with the "fast and furious" crowd seems to be keeping
prices high...

Wow, I just checked some prices and they seem to have gone
up a lot lately! I couldn't find a RZ at a dealer for under
NZ$30k (US$22k approx), and private sales are only a few grand
lower than that. I guess they'd be even more expensive in
the USA where you only have locally-made models? I suppose I'm
lucky to live in a country where we drive on the same side
of the road as the Japanese.

I don't believe you can buy a new one here anymore, but for reference, a
nice, stock '91 Turbo is up to $15,700 on eBay right now.

(By 'dealer' here, I was referring to second-hand dealers).

'91 is the previous model: JZA70 chassis, 1JZ-GTE (2.5L) engine,
and a lot cheaper. A friend picked up one with a bung turbo
for NZ$5k, although good-condition ones go for a bit more --
especially considering that most of the good ones have been
crashed already.

That engine is quite inferior to the 2JZ-GTE (3.0L),
although the chassis is nice (and some would say, nicer).
I believe the first JZA80 supra was May 1993, and the first
VVTi 2JZ-GTE was 96-ish.
