buy a supra or only the 2jzgte?

Sorry I don't understand. Why waste $ on "changed internal components"? The gt4202r is a 1000hp turbo, which perfectly matches the strength of the oem 2jz-gte internals.

Unfortunately, the way to improve 2jz-gte reliability at 1000hp has nothing to do with internals - it has to do with what kind of fuel you run. Run too low octane fuel (for a given max psi boost), and it'll detonate which ruins aftermarket or factory internals equally well. Run enough octane and your reliability is ensured. For 22psi max/peak, you'll need at least 100 MON octane to ensure reliability. E85 would do, and so would a very good meth/water injection system together with 93 R+M/2 fuel.

I don't think it's less reliable...it's just that it's (slightly) more complicated to work with. Also, choices for the intake-side aftermarket cams are more limited.

About $6,000.00 United-States Dollars (USD), from Toyota.

I know that 2jzgte is very strong also with oem internal components, but the question is that if I buy an used supra, i don't know with sure the real miles done (if indicated miles are really miles) and the real condition of internal components. So, i can do only 2 things: or I'll buy a supra with all annual toyota controls and not too much miles done.. but it will cost a lot of money.. or I'll work on 2jgte (used or new it is) with complete rebuilt or internal components, so I can also be sure that the engine and the gearbox are pratically new and very reliable.

For the fuel, no problem, I'll use at least shell v-power (100 octane) and if the car requires more octane, I'm thinking to buy directly one of this gasolines: http://www.extremecompetition.it/eng...sp?categoria=1 .. also because I'll use the car not every day (I'll have other 4 cars in family).. then, I'll do to develop the car by www.ramaracing.it (they are very very good) and they know what to do (they are also excellent on electronic development).

If I don't mistake, I read that the 93/97' 2jzgte is more used for big development.. probably because it's more simple to work.. but I don't know if it is better of vvti 2jzgte (for power).... and I don't know if the reliability is the same for both engine. Otherwise, if choices of some components for vvti 2jzgte are more limited, probably it's better to go on sure and to use a standard 2jzgte.

6.000$? If it is so, I'll buy directly in Toyota the gearbox (i asked the price of empty monoblock and head .. I don't ask for gearbox.. tomorrow i'll go to Toyota to ask...!!!.. ah: Is it compatible the v161 gearbox for 93/97' 2jzgte (that originally is v160)?.. I prefer the v161 for choice of gears (I hope that the reliability is the same between v160 and v161).

THANKS FOR ALL

Today I'm gone in Toyota to ask the price of a new v161 gearbox... here in Italy the price is high: 22600$ (15600 euro) ...
So, if in Usa the price in toyota of a new supra gearbox is only 6000$... i'll buy there. May I contact the usa toyota?
