ok he says what happened. hose of the wastegate popped off...

In other words, he ran too much boost for the octane of fuel he had in the tank. I'd bet any money that if he'd have been running pure 116 octane race fuel, his engine would have been in perfect condition afterwards. My guess is that he was probably running pump gas...

IMHO. i think it would be something too do with the heat in the desert.. pre ignition...

Although external heat is a factor, the engine won't pre-ignite or detonate even on the hottest day, if you're running a sufficient octane level to match the boost level.

Yep bad tuning will kill you every time. For what it's worth, I already mentioned this in post#2, above.

You're sort-of on track. The problem is not the fact that #6 isn't getting enough fuel. The problem is that #6 is getting too much air, because the oem intake plenum is not designed for high boost (eg. 750rwhp+). This is why all big turbo'd mkivs run aftermarket intake plenums (along with race fuel, and proper tuning).

lol. well thats good to know. I noticed that the supra has a sie mounted intercooler. would it be wise to make it a fmic from the start?

I was talking to the guy who is importing the supra. he said he can get a me 6 spd targa? where there factory 6 spd supras with targa tops or was it some guy with an automatic that did a conversion. because if its a conversoin there no way im buying it. i also told him a BONE stock supra. and if he can get a quicksilver supra. i would love it! i read that there where only 27 made?? any truth to this??

My mkiv tt just so happens to be a factory 6 spd with a targa, ... so yep, they really do exist.

33 quicksilver mkivs were imported into the US. I'd guess there were at least as many in the rest of the world outside of Japan, if not a lot more...and probably many dozens if not hundreds within Japan.

ah so there where 6 spd targa's made. awesome! because i can get one but if its a conversion I'm not going for it.

The oem smic (side mount intercooler) is quite efficient, and matches the oem twins at stock boost levels quite well. You can pick up about 15-20rwhp using an fmic with the oem twins, but only at bpu+++ on high boost and race fuel.
