New Project Supra

Twin Turbo '95 · 03-28-2008, 03:35 PM

Im also going to use water/meth injection to cool the engine a bit more. around here 116 octane is pretty rare. I'm not going to make it a one day build(matter of speaking.) im going to drive the car stock. just decats and a good waste gate to keep the boost from going over 16psi. just a few small mods. and then when i get out of school.. yeah im in my senior year. yippy. then i'll start really amping up the power and make it a super fast street car. the fastest supra in SA is only a 13 second N/A supra. so its not going to be hard to be the fastest supra. but i want to get the fastest road car. the fastest currently is a lotus elise. dont know what the 400m time is but the 800m time is 14 something. so its gonna be hard!

Note you can't (practically) run an aftermarket wastegate with the oem twin turbos...you'll need to stay with the oem wastegate.

ok. then I'll just go single a lot sooner than expected. but 'ill start with a small turbo. maybe a T5/T4 Hybrid. then after all the fun and getting the itch to go faster I'll slap on the T72.

When I do start going for a power car. i thought it would be just smart and order all the parts. and then after i have everything then i can start building it. so then the only time i cant build it is if i forgot about something or if something doesnt fit..

i dont know which of the supra's im going to buy so i dont know what the pistons ect look like and how the car was maintained. so i think that pistons need to be on the list.

Honestly, pistons are a waste of $ until you know for sure you've got an engine that needs them. A well-maintained 2jz-gte with good compression #s should not be opened up. Toyota built these engines right, with extremely precise tolerances (tolerances are several times more precise than a 350 chevy). Race fuel and wider rims need to be on your list - not pistons. Just mho fwiw ymmv...

Ime, that would never happen with a bone-"stock" Supra, and I'm pretty sure this has never happend to a "lot of people" (please post those T04R links you're referring to - I know many of those guys, and I can find out more details if necessary). However, if you mod an Mkiv TT up to 'BPU' level or higher, and then try to run 20+psi on pump gas (or run without a boost gauge so you have no idea how much boost you're running), your pistons can melt. The solution to overcome this is to run race fuel when you run high boost. It is NOT a solution to replace the pistons, because high boost on pump gas will destroy any pistons, no matter how expensive they are.

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

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.
