Garrett GT3040.

[RB GUN]

High guys.. im about to purchase a GT3040 + Tial 38mm W/G and a stainless teel manifold. Wat do u guys think about this setup.. considering i have atm EMS computer, BOSCH 60hp Fuel pump, stock intercooler and stock injectors + High flowed T3/T4 which is really laggy. the GT30 im gatting has got the .63 exhaust and .72 inlet.

Ill apreciat any comments and opinions about this purchase.

many thanx

id suggest upgrading ur cooler and injectors

ben...

[rob77]

You will definately need a bigger intercooler, even with a hiflo you should put a fmic on.

[B-Man]

Yup - get a FMIC. You will need 550cc injectors .

Get a 600HP fuel pump too - joking ! !

I personally don't like EMS ECU's - what type is it ?

Possibly better with a PFC, Microtech or Wolf.

Have you got EBC ?? I would recomend this too.

GT3040 is a nice turbo

What manifold are you using ?

PS I have a GTR cooler with GTS-T mounts for sale - see the for sale section ( /end shameless plug)

High guys.. im about to purchase a GT3040  + Tial 38mm W/G and a stainless teel manifold.

This sounds like a GCG Kit... am i correct ??? :wassup:

Anyhow. As others have said.

You'll need Injectors and FMIC before you even can think about the turbo.

I'd also suggest getting the GT3040 with a .82 rear housing.

it wont be too laggy at all.

I'm having one fitted ATM. Will be done in 3-4 weeks.

You may not need injectors, I'm making 339hp @ 70% duty cycle on my stock injectors. The only mods to my fuel supply have been a bosch 910 pump and removing the injectors (to make sure they were stock) to be cleaned and flow tested before tuning the ecu.

[R31Nismoid]

is my calculation correct in saying that it ~250rwkw ???

Good power on stock injectors...

Bringing out a good forumla worked out here on these forums

HP = (370 / 5) * 80% = 59.2 hp Per Injector

59.2 * 6 = ~355.20HP worth through the injectors (that aint at the wheels)

The above 80% being that there is a 20% allowance for cold start/run/ etc.

And your virtually making that at the wheels and not even close to maxing the injectors...

Mind you... i cant remember what fuel pressue that the forulma worked on.

I cant remember it all

So if someone can work out how too allow for the fuel pressure that'd be great!

Thanks alot guys for your comments.. as i talked to my mechanin i asked him to make me one custom manifold and oil lines + custom FMIC installed and ill get the tubo and wastegate...

i heard that i can make close to 240rwkw with this setup even more.. (i wish ).

R31NISMOID: yes it is their deal which is pretty good as i went around and sked other dealers..

So guys any thing else that i need to be aware of?? plz let me know...

And about the injectors i might put the BOCSH 600cc on l8r on.. or if a better deal ill put it now..

At the moment all i want is a 12 Sec. car.

What you guys think i might get down the 1/4 with the above setup???

Thank you guys again for your comments..

I plan on visiting my mechanic this week and tuning for 1.2bar and then hopefully a trip down the drags with some slicks, hoping for a high 11 pass.

you'll make 240rwkw with ease.

more upto 280rwkw.

But your motor wont last the distance.

So 250rwkw to be safe.

As for your run... i ran a 12.9 with 203rwkw so you'll smash a 12.5 or less easily.

Just gotta get the power to the ground

[RB GUN]

Wll thank you very much guys again for your comments..

R31NISMOID, r u in sydney pal...? if so let me know so if we can we meet up and check the cars out..

Cheers

[R31Nismoid]

Nah mate. I'm in Vic.

But i was talking to CGC the other week... that's how i knew about thier package they have at the moment

[Guest INASNT]

Hes the GT30 going in my car at the moment

And manifold

[Freebaggin]

I have GT3040 BB CHRA with T04B 0.6 A/R comp housing machined out. Also Sierra Cosworth internal gate exh housing with 0.63 A/R. I'm using 0.6 comp cover so that it clears exh manifold.

All support sfuff is totally STOCK except injectors (550), FMIC and Microtech. So stock exh manifold, inlet manifold, cams and throttle body.

I am getting 265rwkW (Dyno Dynamic) at 1.2 bar with power dropping off a fraction above 6300rpm, but still 250-255 at redline. I have "full boost" at 3800rpm.

I am very happy with setup but definately less responsive than stock turbo below 3500rpm . I wouldn't recommend 0.87 exh housing, would be too laggy unless absolute top end power is wanted but then only worthwhile with nice tubular exhaust. Heaps experienced tune shops here recommend 0.6 odd A/R, heaps of power can still be made.

So that's the only other thing, I reckon mine would respond really well to nicer exh manifold.

Hey INSANT, could you post a couple more pics of teh manifold? Like one from the other side please? Just curious about the GCG manifolds and how the runners are shaped + welded. Thansk!

I snapped that pic just before it got put on the car about 1 month ago. I had a few problems with the manifold because when we first tried to bolt it to the head it would not seal properly, so it had to be taken off and refaced. They we reinstalled it and when the turbo was bolted on the exh housing was touching the block because the flange on the manifold was slighly angled towards the block, so the turbo had to come off and flange modified to the exh wouldnt touch. Finially its all back together and should have the braided lines and new dumps etc finished. I only had my camera there the first time.

I would not recommend this manifold, and its not a gcg manifold or turbo. I just hope it works well!

[RB GUN]

Thanks INASNT for the coment...

Yeah about the Manifold i talked to my mechanic and hes ganna make one for me You might know him Vince Rigoli... and im getting the FMIC and oil lines at the same time and I might get Injectors done aswell (600cc) as he recomended.... and then fingers crossed for the dyno day..

Once again thank you guys for ur comments and Take care...

Cheers

Also how and how much does it cost to get the turbo POLISHED like INASNTs turbo? wer can i get it done?

I think mine cost me like $60 for sumthing. The shop that built it polished it also

[JimX]

R31Nismoid and Rob77, his info says he has an R32. That would mean his injectors are 270cc, not 370.
