What Turbo?

[Adriano]

Have a look at cubes rb30 setup, he'w running at gt30r. With a .86 ex housing, you will have boost practically at idle, and 300rwkw, with a 4000 rpm torque band, just the thing for hurling a heavy skyline down the road

[tm_r33]

ok im thinking gt3540 at this stage with .82 exhaust housing but curious as to why sven recommended .61????

[R31Nismoid]

gt3582r .82 ar 18psi by around 3.5k and around 350kws easily

I agree 150%, perfect turbo for the 25/30 still giving great response with good peak and a stonking midrange

[R31Nismoid]

Nope.One is a 3040 the other a 3540

3040 is about a 600hp turbo

3540 up to about 750hp depending on housings.

Wouldnt go smaller than an .82 on a RB30

3040's come in 500, 550, 600 depending on the compressor wheel chosen (different part number)

I had a 600hp one, others i know have a 500hp one

yup im agreeded guys. thanks for every ones input. was of great help.

now its 2 grand investment time lol

[WHITER33GTS-T]

My old TD06-20g made 300rwkw on my old RB25 on 17psi.

I have 2x T3/T4s going on my 25/30 but am looking to change to a T51r in the future

[sven]

started looking 4 a turbo yet vagi? or still trying to make the decision first, theres a 3540 on ns.com going cheap or was the other week otherwise theres a few others if your looking into others not mentioned here.

[Guilt-Toy]

GT3540 with .82 will give you 300rwkw on under 20psi (depending on engine setup)

[nizmonut]

I dont think you can go wrong with anything around the GT35 range (either a GT3540 or something slightly smaller, GT3240), they will easily give you the power you want (rated around 600-700HP) and beyond and being a 3L this gives you the displacement to spool it up quickly.

Quick edit: Just noticed you have 500cc injectors, are they actually 500cc or nismo 555cc injectors? Either way, if you want to go much over 300, say 330ish, id probably recommend 740cc injectors just so you arent running the 500cc on such a high duty cycle.

i'd have to agree on both, especialy running a 30 block

im running twin garretts 35/40 one hiflowed the other standard, and bosh 740cc injectors on a low impedance.

rb30/26dett head.

My 2 cets worth, GT35/40 heaps of them around as they are the ones on BA Falcons, proven to make obscene power. I was going to put on of these on my VLT, i think they rock just just my opinion tho

hmm then gt3540 is whats on Eastons r31 black pearl drift car... cause i know he is running an xr6 turbo...

i know that things goes hard too . it seems most ppl are recomending very similar turbo

yer i will be using bosch injectors as my bro ownes the dealer down here

[Billet Ricky]

My two cents.

50 trim Billet R-GT3 600hp turbo, super fast spooling.

56 trim Billet R-GTV 700hp. Similar flow to GT3540R.

Billet Z-P 780hp turbo. Out flows HKS T04Z.

Well you wouldn't promote Garrett now would you?

Your aware of your warning, if your just here to plug your parts, ill send you on a holiday

[DCIEVE]

ok im guessing these are essentially the same turbo with different exhaust housing sizes???

one is .82 and one is .61???

will the .82 mean more lag?????

hey mate, just to clarify for you the 3540 and 3582 are the same thing. Steer clear of the xr6 turbo, boost control is a nightmare with them i found

Thanks DCIEVE

Yes i have worked out they are the same thing lol. too bad no one else could put it so simply lol.

Spoke to "un named" seller today and i can get trade price of $1600 for a new gt3540 with the .82 exhaust housing...

Hows this price???

need to get manifold too, he quoted 900 which is a bit excessive so ill keep looking.

peoples thoughts...???

[dangerman4]

are we talking internal gate or external?

i asume ext.

what brand was the manifold?

[tm_r33]

yes externally gated.

unsure on the mainfold brand!

having a look on ebay and stuff but looks like home made crap. ill find a decent one for a good price if i persist

[Pun4N1]

$1600 aint bad. I was looking at paying $2200 back a couple of years ago, that was for an internally gated one.

[STR8E180]

HKS 3037 or TO4Z...

wtf?

how can u recommend a HKS GT3037 and then go and recommend a t04z

both turbos are no where near each other so how can u recommend one and then the other??

like if u said GT35R and t04z its abit more understandable

IMO

for a Rb30 / 25 setup and aiming for 300rwkw i would recommend the GT35 with .82 exhaust housing

this would be a very responsive setup

DO NOT go any smaller then a .82 exhaust housing on a 3L engine!

LOL +1

Yup as i have heard also. This being due to internal gate i do believe?

Ive gone externally gated.

Yup $2200 is still about right for retail but i got a work account with the peeps im goin through
