I'm looking at a good offer on a GT40R turbo wit T4 footprint
3 inch outlet

specs

Turbine:
Wheel: 77mm w/ 78trim
Housing: 1.06 ar

Compressor:
Wheel: 88mm w/ 52 trim
Housing: .58 ar



My engine is a 13B-REW with a large streetport (Ito)

Engine will get allsupporting mods if this turns out to be a suitable turbo vor my need.

I'm looking for a good/fast spooling turbo that can reach about 400hp and remains driveable without too much lag.

Advice would be highly appreciated

 

yea that's the gt4088 and should spool pretty good honestly. i wouldn't worry about it, and 400whp is nothing on that one. that's pump gas territory no questions asked

 

easily at like 14-16psi depending on your port and mods.

 

get a water/meth injection kit and you can break 500rwhp on pump gas

that turbo is actually perfect for your needs

 

not to try and thread jack but im lookin at the same setup was wondering when u would see peak boost with this turbo.

 

look at this:

could have been better though...

 

How much are you getting it for? If you're not interested I'd like to buy it for the right price

 

so this is basically some kind of a T88 kit but ball bearing?

The kit is not in the US so I guess it's not interesting for you guys

 

No, I think it's almost like a t78 but a lot less lag, how much are you getting it for?

 

I'm looking at about 1200 USD for a brand new turbo and manifold without shipping. No other parts included

 

how much just for the turbo and no manifold?

 

GT4088 is indeed a VERY nice turbo. You shouldn't need more then that with your goals.

 

http://fc3spro.com/TECH/TURBO/tmodels.html (you will have to convert measurements to metric)

FYI: T88 = TD08 turbine, TD08 compressor (vs T78 with TD07 turbine, TD08 compressor) . based on the numbers on FC3Spro.com , the larger T88 (TD08-34D compressor) is 95mm exducer, ~70mm inducer, 54 trim. So the GT4088R is smaller than the 34D T88 and it is ball bearing.

Greddy also makes a TD08-33D T88 turbo which is ~66mm inducer, ~90mm exducer, which is pretty close to the GT40 but technically still a little bigger in terms of the size of the compressor wheel.

 

Do it Neal! If you're not interested in the kit let me know who's selling it. I need some more power to match the looks of my fc.

Voor die prijs kunne je hier zelfs geen GT35R kopen.

 

if you see that you want more power later you could always add a water/meth injection kit for more power and reliability

 

Yeah I was reading the Howard Coleman thread anout Auxiliary injection and I'm really considering a water injection kit after everything is installed. Just doing some research on hte newer HD AI kits that can be connected to the ECU

Also looking for a PFC map to get this setup running.... hint hint :d

 

thats the 4088 as mentioned, not a 40r. the gt4088 is journal bearing which makes a differance obviously. the gt40r should get spool a couple hundred rpm sooner and produce a flatter torque curve, all with a good tune obviously.

 

Looking for a map for this setup

- new rebuilt 13b rew
- judge ito aggressive streetport ( large)
- 550/1600cc injestors
- HKS twinpower
- full 3" exhaust
- double throttle removed
- all emissions removed
- 3 row intercooler
- HKS ssq BOV
- APexi power FC
- LC1 wideband
- Datalogit

A map for thesame setup with 550/850 injectors would be appreciated (running stock 10 psi boost)
