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

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

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

now its 2 grand investment time lol

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

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...???

are we talking internal gate or external?

i asume ext.

what brand was the manifold?

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 :wub:

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!

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

LOL +1

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

Ive gone externally gated.

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

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

    • Yesterday's day in review: All the wiring to the lights up the front how I want it, is ran, terminated, and all to length. The only lighting up front I haven't finished is the side indicators, as I need to get to the partly cutup factory loom, and find the plugs for them. Interesting note, the side indicators use the exact same plug that's in the doors for something else that I don't remember what it is... So that plug better be careful...   Power steering solenoid, on the R33 is variable, and from memory PWM. The Ford's control from the docs I have so far, is it's just a on or off control. So I'm not sure it's what I want, and in any case, power steering running, but at its heaviest (solenoid off) is likely what I'll want anyway, so I'm not yet touching it at all. All the wiring I can complete so far, is done. There are 3 wires I need to make a plug for at the ECU, and these are just for the vehicle speed sensor, of which I need to get a T5 from an AU, so I can use its output that has the speed sensor on it. (My car doesn't have ABS, otherwise I'd set it up to use one of the ring gears on that). I need to buy new headlight globes and front parker globes, otherwise I could show photos of lights working. Current fuel lines in and out on this motor are "5/16". I'll order hardline, and some AN fittings for that, and I just need to 100% check fuel line size at the tank end, to get the ends for it. I'm also looking at a few options for the banjo bolts to AN fittings for the power steering rack. I'll pull the reservoir off the Barras PS pump. There's an off the shelf fitting for that pump for a -10 AN feed, and it'll use a 16mm to dash -6 an outlet to feed the rack. I'll be making my own power steering reservoir, I'm going through the thought process at the moment of how I'll run the baffles, and I need to research another idea for it too.
    • Two inlet runners changes the engines characteristics requiring less fuel to make torque at different points in the rev range. The smaller diameter inlet runners on the DET increases air flow speed, which improves atomisation of fuel, particularly in low load/idle for better burn, and in specific areas of the engine, (areas you would use when driving normally) increases the efficiency. All of those items change how efficient the engine is at different speeds. The changes on the neo help slightly to improve emissions where it matters. The overall improvements won't be the likes of going from an engine built in the 70s to an engine built in the 2000s, it's just a small step. But still leaves it the RB with the best chance of improvement.   As for your comment about the whole using a cat to not need to worry about those gases. Two things, no system is 100% perfect. It won't eliminate everything. So reduce the quantity you put into it, you still reduce the output. Two, make that system do less work, and it's likely to survive a little bit longer. Funnily enough to, one trick employed to get cats up to temp, AND to drastically reduce emissions before they get up to temp, is to reduce ignition timing.
    • Maybe I should have written that a bit better lol. I did come 8th last in English at school during the HSC, ironically spent 2 decades reading/writing specifications and contracts in IT 😂
    • Right, but that's in-cylinder, there's the interaction between that and the TWC which complicates things. Pulling out timing to reduce NOx is a strategy I saw in transitional emissions vehicles like stuff from 1974 or so. The two inlet runner system is interesting but I'm not sure it makes a huge difference as far as emissions goes, is it a tumble valve? I've seen stuff like that even in cars from the late 80s. 
    • Hello all,   so i recently swapped out my rb20de neo with an rb25de neo( engine,transmission, wiring and the diff everything) but i just cant get the gear indication light on the dash to work when i switch to tiptronic mode. Note there is a steering wheel switch beside the shifter and i dont have that. I did notice yesterday while switching to tiptronic that the indicator on the dash started to work but it didn't afterwards. Does anyone know how this actually works? Or do i still need that steering wheel switch to be connected and on for that gear indicator to work?
