Gtx4294R On A Rb28?

[ISLIDE013]

Hey guys,

I'm looking to upgrade my turbo

Currently running a t04r but want to upgrade to the equavilant in the gtx range.

Would that be the gtx4294r?

Ive heard rumors such as more response than a t04z yet almost as powerful as a t51r.

Any1 used or heard of anything about these turbos?

Very interested but scared of the size they are.

T04r can on full boost a 5k so looking to either keep or improve that.

Also looking for 500ish kw at 4 wheels atleast as was makin 460kw with the t04r.

My car currently has 280in an 272ex that I was thinking of changing to both 280s.also 2.8 litre stroker.

All other turbo sugeations are greatly appreciated.

A quick google found me this. Its a much, much bigger turbo than a t04. Most people quote them as a 900hp turbo, which is way more than what your aiming for, so in my non expert opinion, its way to big. I really don't know what is the best turbo for ~500kw though, but probably something a fair bit smaller.

[ISLIDE013]

Yeah your right

It sucks as need to run something t4 flanged and been hearing how t04r and z are old technology and wanted to make some more power without too much extra boost as I'm running 22psi already.and seeing as the gtx4294r has better response than t04 series turbos was considering it.How about gtx4202r? Or will the gtx3582r make the power with response I'm after?

Dude, use some common sense.

The GTX4294 is a BIGGER turbo than your T04Z and will be laggier.

What are you after? More response? Or 500rwkw? You cant have both.

GTX35R will be more responsive than you T04Z (350-400rwkw)

GTX4294 will make 500rwkw (5500rpm>)

OR

Run 30psi through the T04Z.

what fuel are you running?

just up the boost and run e85

[ISLIDE013]

A lot of 2jz are now running gtx4294r or it's smaller brother gtx4202r and claiming to have same and better response than a t04z and can achieve t51r like kw and they have tried t04z before hand.i wouldnt mind more power but than again same power with more response would also be good.im really looking at the gtx4202r now,just read that a 2jz starts seeing bOost at 2500rpm and on song by 3800 rpm.im also running pump but I don't know if I an be bothered changing my fuel system to suit e85 and order it by the drum.i do t trust servos either

[sneakey pete]

what about a 4088. About the same size as a to4z isn't it?

[NYTSKY]

Try again mate. The GT4202 is a 1000hp turbo, BIGGER than a GT4294 (850hp)

The GT4202 is also the same size as a T51 so its no brainer that they would be making similar power.

A 42 size turbo at target boost by 3800rpm??

Show me these results and ill buy 10 of them.

And if are serious about more response and more power the turbos I would pick:

TS GT4088

TS FP3794

I'll try find the thread again in the supra forums,also im talking all wheel power not rear.the 4088 looks really good.i might still run the gtx4294r but I'll do a little more research.i don't mind lag too much as my t04r for some reason comes on at 5grand.

[ISLIDE013]

Also what rear housing do you recommend on the 4088? As apparently .95 start choking at 630hp I read On that gtr.uk site

also keep in mind thata supra is a 3l and a complete different motor to n rb26 even if you do have a 2.8 kit
