No probs man. I wont worry about pfc for a few months, in no rush at all.

[tridentt150v]

If you get a 3071 and front mount you'll need a pfc, personally I'd trash all that advise and go with a wicked set of blue or purple neons...............street cred is where its at.

I know, I know..................just kiddin'

Actually if you get the 3071, for the $680 I'd definitely buy the fitting kit as well.

PS I have a 3076 and it is a very good turbo, so the 3071 would be just as good with a bit more down low, I've seen guys on here claim 270+rwkw from them. They are basically the equivalent of the HKS gtrs [different ex.housing]. The HKS turbo's are made by Garrett anyway.

Turbos are for pussies.

Neons and a veilside kit bro. Set of those sick vault star chromies too. bollocksin hektik matey.

Probably want a monster tacho, too. Those chrome wheels send your engines rev limit through the roof so you'll need one that goes to at least 12.

Uleeeeeeeh.

[tridentt150v]

he did say 'light mods', so I reckon fitting neons is kicking goals

O O O and stickers, don't forget a heap of stickers on the door - HKS, Greddy, Tein, Tomei etc etc

You're going to need NOS. Dont forget NOS.

Hola, como estas?

I have found a turbo I think would suit thhe power I am after. Does anyone have any experience with the garrett GT3071R or know a little about it??

Gracias

Hey Stevo,

Thats funny, I have a GT3071R on mine... Although I bought my kit for $1900.00, so the price on that link is CHEAP!

Great turbo for response and mid range power and torque... But even though it says that it is a 550hp turbo, dont expect to get more than 240 - 250rwkw using one of these as the rear housing is actually quite small (which gives you the response).

Im running 18psi at the manifold - about 20 at the turbo and mine makes 236rwkw, but the torque is the best thing about my set up as it makes over 550nm at 4,500 - 5,000 which is a great feeling and more than enough to pin you into your seat (and smoke tyres ).

Note: My car uses an A'Pexi Power FC, Front mount intercooler, big exhaust, Splitfire ignition coils, 550cc injectors, Bosch 040 fuel pump etc. you wont make as much power without extra mods if you bolt an aftermarket turbo.

I would only advise getting the 3071R if you are looking for a really quick and responsive turbo that will give great mid range and reasonable top end. If you want heaps of power I would reccomend looking at a GT3082R or something high mount, like a 3037R.

Here's a pic of my dyno tune (the car has made more power since) - have a look at the curve, there is almost no lag and the mid range is excellent.

G'day Mick,

That is all very interesting. How come you didn't get the GT3082R? Where is most of it power in the 3082 if the GT3071R is more mid-high range? I actually wouldn't mind more power than 240kw so maybe the bigger turbo is a better option...

[datto260Z]

hmm, might have to look into this 3071 thing, anyone want to buy a slidewise type turbo for a decent price?

[tridentt150v]

If you want more power than the 3071, go for the garret GT3076 [equivalent to the HKS 3037].

My dyno results are here:

http://www.skylinesaustralia.com/forums/Rb...0&start=380

and 12th entry down.

The big difference with a 3071 vs any turbo that is bigger is you need custom dumps, intakes etc. So pay say $1700 for the turbo and then another say sub $5000 for setting it up.

The 3071 bolts up, and with the fitting kit, sort of uses the std set up, the 3076 may do this as well, but your throttling it and it won't see anywhere near its full potential.

The 3076 is [one of] the ideal turbo's for the 25.

So your saying for what you get out of the 3071, although lacks a little overall power still outways spending big on custom mounts to fit say the 3076 or higher?? You did mention the 3076 may bolt on but unlike to 3071 it doesnt say this on the garrett website...

Your results are very impressive man!! I'd love for you to take me for a drive one day

[tridentt150v]

I personally don't know of a bolt up kit for the 3076 [there could be one, I just don't know of it]. If you did find such a kit, things like your filter, dump, exhaust, manifold etc would all hold it back a bit, you'd end up with something that is unable to work [huff] properly. I had to get all my stuff made up and it took a lot of mucking about to get sorted and settled. Its not cheap!!

This is presicely why many ppl opt for the HKS kits, they are a bolt up system. They are very $$$ to start with, but probably cost less in the long run.

I didn't do this because I had a clear plan on what components I was going to use and my goals.

The reason I didnt go for the GT3082R was because it was about $400 more expensive and I dont think youre able to use the standard air flow meter or inlet pipe (from the air filter to the turbo intake) because the extra suction sucks it closed, and the extra air mass is to much for the standard air flow meter (I could be wrong about this) so you will need an aftermarket pipe and probably a Z32 300zx AFM.

Results from different engines will always vary quite a bit, you might make more power from a 3071R than me for some reason, you dont know until you have done it.

Dont get me wrong, the GT3071R is a great turbo, just dont expect 300rwkw +

Yeah fair enough. Well im in no rush so maybe ill hold out a little longer and depending on funds choose a path that i should be able to back up with $$ if need be. Im extremely impressed with tridentt dyno figures and even though its alot more dosh it might be something worth saving up for....ill see.

[R3sp3ct]

I was just reading up again on the 3071 that "bolts on" to the RB25 which costs $1690. If it bolts on why do you need to get the fitting kit which is worth $680 extra to fit the turbo??

[widebody32]

depends how much power you want so work out what you want.

You can make up to 270 kw at the wheels on standard injectors by upping the base fuel pressure via a adj press reg as i have done a couple now back to backed on various dynos. These setups had Adj exhaust gears, a gcg turbo at first which was rebuilt by Mrturbo with his core due to failed gcg cores,aftermarket ecu, pistons but can be done with standard as long as the tune and boost are kept to a minimum,splitfire coils.

I have also done one with standard internals using power fc, front mount, garrett turbo,adj FPR and exhaust gear which made 270rwkw and has been doing it for two years now.

So if you are only after 240 or so you can definitly make it on standard internals with just minor mods
