Garret 3040 On An Rb30

[Duncan]

with a standard rb25 head, external gate

what is the max boost it should run?

what revs can I expect full boost?

about what power?

the workshop is recommending against another china turbo against my better judgement....

[R31Nismoid]

On a 2.5ltr i ran 17psi 270-280rwkw and it was on by 4000-4200rpm.

370rwkw on jungle juice @ 24psi... lots of room to move.

18-20psi with a 3ltr you should see ~330rwkw on PULP without a drama.

You'd take a rough guess it'll be on nicely around 3300-3500rpm with a 3ltr.

Lets see your china turbo do that you tightass accountant

[Duncan]

nah too high before it comes on boost then, I must need something smaller. I like 14psi at 2000. and 250kw is more than enough too so I think this one is too big.

thanks tho

[Duncan]

I should restate my goals instead of asking about a turbo.

Looking for 250-280kw, with full boost at very low revs. top end > 6000 not important.

ive got a cheap china turbo on ny 30 atm (TO4e with a 0.62? rear) make 14psi by 2000 but then drops down to 10 as its physically chocking the exhaust. still makes 230rwkw at 10psi though.

im getting a GT35r for it now

[Duncan]

yeah china t04e is what I am running now. 260awkw @18psi. full boost at 2000. external gate, it holds boost perfectly all the way.

they break a lot which doesn't worry me...but the mechanic is trying to talk me into something more expensive.

[Sir Lord Van Von Vader'ham]

hmmm. sounds like you done the same thing for the same reasone i have. its weird that urs is flowing fine, as my tuner had said boost issues with mine (using the ViPEC for EBC). My tuner is also the one pushing for a Garrett etc

conspiracy???

try for a 3071?

a 3076 is seeing positive boost at 2000, so the 3071 should be better suited to your needs.

spend the money duncan by the time you replace your china turbos once a year you might as well have just bought a decent one

pfft, 300 bucks and 30 min work. thats like 7 years worth

Hi Duncan

I have one on the R33. You are welcome to try it out.

[KiwiRS4T]

Get a GTT highflowed by Gcg that should do it.

yeah that's how the maths looks to me too....but I did commit to looking into something else. Strangely the turbo importer does not think they have to warrant the turbo when it fails

Hi Duncan

thanks mate....might do...standard capacity, head and cams right?

I'll check out 3071 and hi flows I guess, maybe gtrs. I was assuming the hi flows and gtrs would be a little small on a 3l even for response, maybe not.

[NYTSKY]

My tuner has one on his 30.

20psi by 3500rpm and makes 320rwkw.

[fatz]

ill see if i can get you a decent china turbo

[Harey]

I wouldnt use a high flowed GTT turbo by GCG as the main benefit is the standard exterior for legal reasons. Sure its a reasonable turbo but for the cost of over $2k you can get a much better turbo.

I would be careful that you dont completely strangle the engine with a restrictive turbo, I wouldnt go any smaller than a 3071 on a 30. How bout a 3071 with 0.63 housing? That would be ridiculously responsive.

Hi Duncan

WHAT ABOUT A HOLSET ?,Cheaper then other`s & better build Quality then most & lot`s of Options,

Good luck in your Quest ,

Cheer`s Chuckie.

Standard RB25 cams etc (but HKS cast manifold). It would give you an idea of how it delivers power. Obviously the extra cubes is offset by the extra weight of the stagea so I would be a fairly close comparison.

I'll pm my number.

[butch]

are you using a standard manifold??(exhaust) . i got a cheapy kkr 560 but was a rip off of one. im using an external gate (progate 45 mm on my 30)because the original one is opening at 20 psi. garret gt30/40's are now known as gt3082 .

[Duncan]

Its got a china stainless zorst manifold and china front facing plenum as well.

From looking further there must be at least 2 or maybe 3 different turbos called 3040 because people mention .63 all the way to 1.02, and peak power ranges from 270 to 330. If I go one of these I'll make sure its the smallest one.

still looking into another china turbo too.
