ok, so my stock turbo died...

A.Im planning to get
Turbo : Garrett, Series : T3 shaft, Rated HP : 400HP, Compressor Housing Size: AR.60, turbine Housing Size : AR.54
Tial MV-S 38mm wastegate
3" Down pipe and screamer pipe
aftermarket header (T3 bracket)

B.i plan to run all the above items on my
ST205 stock ECU
Stock 540cc injectors
stock ST202 fuel pump
3" straight flow piping (downpipe to muffler)
stock WTA IC

Will items from B be suitable to work with items from A?

my concerns are:
1.boost creep
2.overboosting

I probably would upgrade your fuel pump. Walbro 255 or Supra fuel pump preferrably. Don't think the stock fuel pump will be able to keep up. I think everything else SHOULD be suitable.

Most concerning is definitly your fuelpump. Am I right to assume you're running a swapped st202?
What powergoals do you have?

a GT3076 will make your power levels nicely. you need bigger injectors and i dont thin kyou should use the stock ECU. get an Apexi Power FC

im planning to run stock boost for now...

my upgrades in the near future are
fuel pump
fuel regulator
boost controller

and plan to achieve 350BHP...possible??

will the supra fuel pump be able to sustain that?

smmay,

wouldn't the GT3076 have a serious turbo lag on my setup...my goal is < 400 BHP?

my ultimate setup is:

Turbo : Garrett, Series : T3 shaft, Rated HP : 400HP, Compressor Housing Size: AR.60, turbine Housing Size : AR.54
Tial MV-S 38mm wastegate
3" Down pipe and screamer pipe
aftermarket header (T3 bracket)
Apexi PFC or Emange ultimate ECU (KIV)
800cc or 1000 injectors (KIV)
Profec B boost controller (KIV)
FMIC (KIV)
Walbro 255
SARD fuel regulator

and target 400BHP or 330-350fwhp

Maybe he was talking about the GT3071. Btw, would you ever consider one of the borgwarner EFR turbo's. Expensive but would be interesting to see one on the 3s!

no there will be no lag, its a dual ball bearing turbo on a 2L engine, i know of several 2ZZ-GE running a GT3076 (GT30R) and there is no lag. i run a GT35R on my 2ZZ-GE and i dont notice any lag, it spools up real quick and im making 545 to the wheels.

Supra fuel pump should be fine with that. BUT, if I'm not mistaken, I think the Walbro 255 pump is about the same as a Supra fuel pump & it costs less.

i finally went with a turbo rebuild and upgrade...

as follows:

1.upgraded to steel turbine
2.port and polished intake
3.upgraded to TD06-20G compressor wheel (inducer diameter is 52.6mm compared to the stock 48mm)

looking to 1.5Bar of boost once the fueling gets upgraded too (~350-380BHP)

Thx for your inputs guys!

stock ecu WILL pull timing how are u gonna boost over stock fuel cut

the supra TT pump is like a 290lph or something. ill look it up then edit with specs.

its a 300LPH

also, to avoid boost creep, get a Tial 44 instead of the 38mm. i had boost issues with a 38 until i upgraded to a 44. then it was rock solid!

http://realstreetperformance.com/store/pag...son-test-5.html (great aftermarket fuel pump comparison..makes you wonder why ppl even care about walbro pumps)

http://www.alltrac.net/tuning/fuelfaq.html (supra pump install info, and great comparison with other pumps.)

If it were me, id go with an aftermarket brand new pump. Why you might ask?!?! Simple, you could get your used supra pump and not even know how much life is left on it..even worst you could buy one brand new, which i dont see why anyone would ever do that when you have great ones that can be had for less that 160usd these days.

i'm still running the stock turbo hence stock wastegate...

btw, what turbo are u running? and at what boost levels? mind sharing?




i 2nd that!

hello guys if any one know the stock rods pistons camshafts and the other stock on engine , will stand on the 350 hp ? or not

on 3sgte YES, will it be reliable? Maybe, might want to put water/meth injection to not melt the pistons...

Hi,

i just saw one people running a EFR6758 on a 3S-GTE, i'am told 1bar @3000rpm, but the smaller 6258 will fit your needs better

http://www.turbodriven.com/files/pdf/179359-EFRTechPages.pdf

i think there is no counterpart on the market yet that can kick the EFR series in performance

greetz

Wow sunny thanks for that link....its finally good to hear some news on how these EFR turbos are holding up!

I hope my EFR boosts 1 bar at 3krpm my KKR wouldnt spool up till 4500RPM
