damn. and here i thought a aftermarket piston would hold up a bit better..

i poked around and read a shit load of topics(again.. read all of them )

TO4R.COM

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

TO4R.COM

he didnt say what happend.
IMHO. i think it would be something too do with the heat in the desert.. pre ignition.

TO4R.COM

he ran a bit lean.

NOTE: they all had a piston 6 meltdown. not any other. 3 guys. same pistons. different reasons. imho. I think that if i get the fueling right for the #6 piston then it'll be ok once i start modifying it

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...

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).

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.

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.

1993/6 TOYOTA SUPRA RZ Twin Turbo 6MT- Kms: 93,000

TWIN TURBO 6MT, One Owner Car, 17" Rayz Volk Racing Rims, A/M Exhaust, Ultra Turbo Timer, Adzest CD Deck with 10 Stacker in Boot. Apart from some paint fade on the bonnet the rest of the body is in excellent condition. The interior is very clean and all the electrics are in good working order. The car has had a front accident repair which after inspection is clean and straight. The repair was to the front cross member and inner panels. This RZ Twin Turbo 6MT Supra has a lovely set of Rims and the interior and exterior are about as clean as they come. The engine sounds good and overall this car is a great package.

Where are you importing it from? What company are you using or buying from? I am interested because my brother is looking for a honda from japan a real right hand drive so if your gets here in good time, and is a really good car I would like him to buy from the company you used. I had some one I knew buy a car over seas and it never showed up so I don't want to get a case like that.
