gt 4088 turbo

m1tch · November 03, 2009, 05:44:50 PM

Just to put my 2p in, I had a chat to James at JM garage, who has spoken to universal turbo about turbos on rotaries, its apparently best to go with a non BB turbo due to the heat generated in the exhaust of a rotary, which is good news as non BB turbos are cheaper

Is there actually any difference bhp figures for the 4088 and the 4088R?

i got my gt4088 from gt3 on ebay.
its still in the box
same with the kg parts fuel kit.
just need a cheap intercooler + fuel pump, and we can go get it all fitted.

The intercooler i got was 250, it is front mounted, off of ebay from someone call 2fast2cool i think, it is quite big and fits in easy enough behind the bumper, dont think it would fit behind the standard bumper though. When sat in traffic, the air temps never go above 45 C. Im sure if you give Clive a ring he would sort you out with a fuel pump,

Hi there, what was it like? does it look ok? Im looking at getting mine from GT3 as they are selling the non BB sort.

Looks good. quite a heavy lump lol.
Cant fault GT3 all arived etc. not the quickest ever delivery but was reasonable.

I got it as it was recomended by Jaydee and Kerim. i have had the engine ported with a large street port. so should spool it up just fine.

The manifold is a TopSpeed one (China Stuff I guess)

it\'s a T4 divided. I had to open up the bolts in het flange (to motor) a bit but apart from that.. no

When the turbo is on, the cold side (snail) is VERY near to the wheel well. but with a bit of fiddling (Dremel) or a good hamer punch it can be fixed.

Other than that, no issues. I plan to have some reinforcements added just for peace of mind

Awesome, thanks for the info, it seems a proper turbo seller on ebay, rather than those cheap chinese copy ones that explode :rollin

It was Kerim that build my large street port that my gt4088 is bolted to. If you haven\'t already I\'d change the fuel filter. Mine hadn\'t been changed ever it appears as I was maxing out the injectors (850prim 1600 Sec) @1.1bar. Now run 1bar but with a new filter max I hit is 75%. Come the spring going for 1.4bar

was it mapped at on the road or on the dyno, thats the turbo im looking at but not sure if it will hit the power numbers i want, do you know what power your making?

m1tch · November 05, 2009, 07:30:13 AM

On lee\'s car with 850 primarys and 1000 secondaries he is maxxing the injectors out and getting 500bhp, what does the wideband O2 say you are running? How do you define maxxed? 85% or 92%?

Cashpoint · November 05, 2009, 09:58:31 AM

Car was mapped on the road, don\'t know what figures it\'s making. I\'ve always thought of figures a something to talk about in the pub or to brag about. So long as it feels quick I\'m really not that interested in the figures a car makes. Having said that I\'ve got dynoluicous on my iPhone and been playing with it in the weekday car and it\'s giving me figures that don\'t seem to out for a diesel

. Will give it ago over the weekend if the weathers good.

m1tch as I said the filter was blocked so maxxed was maxxed 100%. so rev limit was dropped to 6k. When i change the filter you could tell the old one was blocked as it was hard to blow through it.

What sort of power are you wanting? 500 BHP(flywheel) is what i have learnt for the 4088. The car wont take much more will it? With it being so light etc, would the rear end have to be changed to stop car destroying itself? Diff?
