Hi guys,

As some of you know I'm on the market for a bolt on turbo upgrade in my streeter R34, with the aim of achieving a responsive 250rwkw (want to run 12's?). Now through my research I have come across a 2 options and I just want to know if any of you have had experience with any of them or which option you would consider best value for money.

1) GT3071R (Quoted by Paul from Street 2 Track)
GT3071 - $1,380.00
Adapter bolt on - 387.00
Oil lines x 2 - 86.00
Oil drain kit - 19.00
Water feed kit - 17.00
Gasket kit - 17.00
Fittings - 11.00
Shipping - 65.00
TOTAL - $1,982.00
You will still need to modify your Air Intake and Boost pipe, as I am sure you are aware. (Couple of extra hundred here??)

2) HKS 3037 Pro S (previously on a WRX STi and bolted onto standard dump, turbo only, second hand, 10000km, Compressor Trim 56T, A/R 0.87, Inlet 80mm, $1550)

I have an aftermarket JJR 3" bellmouth front/dump and standard manifold, so would I have difficulty bolting the HKS setup up? Am I missing anything else fundamental. So basically I'm tossing up between the extra quality of HKS at the loss of an incomplete kit or a near complete Garrett kit.

What do you think?

[NJA82]

Garrett make HKS turbo`s anyway mate so dont orry about the quality difference, in all honestly i would go with the 3071R Brand new bolt on kit. First off its new, so if treated right will last forever, secondly its a kit made to be low mounted ( as far as i know Most HKS 3037 kits are made to be high mount external gate setups and dont have an internal wastegate? ) and the 3071R will definately be more responsive and be better for stock internals, the 3037 is more suited to a built engine with large cams and big boost.

The 3071R should make 250rwkw on a medium boost level of around 12-15psi on an RB25, with minimal lag, this is an extremely safe setup, although if it was my call i wouldnt buy either of these turbos for your goal in mind i would be looking more along the lines of a 2871R ( aka HKS GTRS ) , this will make the power you want, with more response than either of the turbos you mentioned and the HKS kits if you went that path are a direct bolt on and include all gaskets etc., a little more expensive but hey its a one off purchase and if its done right the first time wont need touching again, Have a read around about the GTRS setups and the power levels they make on an RB25.

[kit casper]

Haha yeah I guess I was getting a bit ahead of myself with the 3037, I think I just got caught up with the fact I could get a HKS more than anything. However, the one that I found did have an actuator attached so I assumed it was internal gated, so it would bolt to a low mount setup I think.

Following your suggestion I did look into the GTRS kit but I can only seem to find it offered by Nengun and a kit would be over $3k landed?? Anywhere else do good deals on HKS kits? Can't really understand the price of the things, considering I could get a Garrett 3071R (HKS 2835 Pro S) kit for a $1K cheaper

Get the best, Get a greddy

[kit casper]

So what is blueprinting? Never heard that term before. I thought the only thing HKS produce are the housings and the internals are all Garrett?

[200sxxx]

pretty much balancing etc, optimizing the engine for its purpose

before you upgrade try get some people to take you for a spin in their car to see what you like, everyone is diferent

[creatd vl turbo]

garrett is good, hks is even better.

[kit casper]

Ah ok, so it is a means of testing and evaluating each change to variable. Sounds logical.

200sxxx, problem is I don't know many people with imports But would definitely be up for someone showing me what their setup can do.

[robbo_rb180]

if 250kw is your goal garret 2871r, there is a r33 getting around with 1 260kw@wheels, responsive as hell.
if you are set on a 3037 go a .72i/w rear housing it will easily make the power you want and still be responsive with room for more.
don't waste your money on the "JAP" brand, garret will suite your application and the money you will save will get you your supporting mods for that turbo.
thats my 2cents worth.
if you want to have a look at my setup give me a call

[kit casper]

It would seem that I will be going with a GT2835 Pro S kit in 0.87A/R internal gate!! (Price dependant). Sounds promising, I will let you blokes know how it goes.

[200sxxx]

If it was my car I would be sticking a t67 25g 10cm kit on

Much easier to work on the car and you always have power on tap
once you feel the excitement of a bigish turbo you will never downgrade, gets the adrenalin pumping
Be prepared to spend some money when components break though
low mount turbs are z gay in my opinion to much screwing around

[kit casper]

Yeah but for my purposes it would be massive overkill, not after 300+kw and the accompanying mods to suit. I was under the impression that low mounts are ideal for less 'screw around' factor as there aren't as many aftermarket parts required. I mean top mount setups look real impressive, but once again I can't justify one on my car as it's a daily.

Rob I will hit you up next time you head up Mt Stuart

[NJA82]

Wow a 2835Pro S is a pretty decent sized turbo... i hope you realise that it is going to be quite laggy mate... As Rob said, 2871R is the ideal choice, i agree with him totally, jap brand name is great but its only a street car go with whats new and whats more suited. And just FYI Garrett make all the cores for HKS, the only thing HKS make is the housings and the specs are simply sent to garrett for the cores to be made. R&D or not you cant beat the HP for the price of the Garrett turbo`s, and the 2871R 52 trim ( AKA GTRS ) is EXACTLY the same turbo as the HKS variant, not similar, EXACTLY the same. Give Morrie at Horsepowerinabox a call and talk to him about doing you a setup with one, im sure you will get it cheaper than the 2835 and it will be brand new with Full Garrett warranty.

[NJA82]

But yea only if your keen to stay low mount, i agree with Christian though about the high mounts, very very easy to work on and a lot more simple of a design, a lot more expensive initially though and a lot more defectable when it comes to the law as well, if you can get away with low mount in a street car do it, it keeps the heat down under the car and it keeps it stealth and legal.

[starlet666]

all this talk about a 2871r is making me want one more and more too noel HAHA

STOP TEASING ME!!!!!!

[NJA82]

You dont need anything laggier Tim, shit you wont be spooling that thing till 6000rpm

Got enough power already for the size of that thing!!! Just get it tuned already mate

[200sxxx]

Yeah for a nice streetable upgrade 2871r is a good pick except if you drive a starlet haha
plenty of different trims as well to pick exactly what you want
whatever you do do not highflow the stock turbo! biggest waste of money

[kit casper]

Have you had a bad experince with high flowing a stock turbo? By all accounts I have read nothing but good comments on GCG high flows in particular, and they have been putting out around 230rwkw on rb25's.

So consensus is leaning towards a Garrett GT2871R. Any of you guys have one installed and want to take me for a drive this week?

[200sxxx]

no they work perfect but you might as well just buy a brand new turbo for the same price or cheaper then highflowing

then you can sell the stock turbo for at least $500

My mates r34 gtt runs a gcg highflow plus supporting mods makes 240rwkw atm
104mph over a 1/4
I have driven that and for an r34 would definitly be aiming for upwards of 260 if you want to run 12s, plus a rear end to get the 60 foot times down

[kit casper]

Yeah you are damn right about the price (GCG quoted $1750 for high flowing and $155 for a heavy duty actuator). Nearly pays for a full Garrett kit!! I have been talking to Paul from Street to Track about the a Garrett kit at the moment. I might get an additional quote from horsepowerinabox like NJA82 suggested also.

What does your mates R34 look like? There are quite a few getting around town these days Certainly kills the uniqueness factor!
