Gtr Turbo Upgrade For 340rwkw

[druzilla32]

hey,

what turbos should i be looking at for around 340 4wkw?

HKS 2530's?

[manage13]

Get a set of HKS GT-SS. Super responsive turbo and it will easily get the 340rwkw.

[R31Nismoid]

~20psi 2530's

[druzilla32]

what about single turbo's?

i think i would prefer single turbo conversion now because its so much more simple.

im after a responsive single turbo.. after about 300rwkw +

thanks..

oh and where in brisbane sell single turbo conversion kits??

i would like to buy the kit pretty soon

[manage13]

With the single turbo kits there are a few options you have, but as far as response these turbo’s are a grey area for me.

1. Garrett GT35R with 0.82 housing is pretty good. It will get you to the 300 mark you are aiming for. There are a few members on this site going in that direction. Wouldn't hurt to read Shaun's post on his engine build up.

Also you will have to source a manifold and gate.

2. HKS T04R. Do Luck is using it on their R34GTR. I will provide you with a quote from HPI magazine vol 40 GTR special #4.

"Rated to support over 600ps, these are very popular bolt on kits in Japan. They are generally considered to be the largest kit you should fit to an RB26 with a standard bottom end"

There are more turbo's on the market but I am unaware of any that is as responsive as these units. But having spoken to Sydneykid about this matter, he recommends the HKS 2530 units over single conversion. Personally, I agree with him!

i have got this quote for a twin setup

Low mount, twin turbo set up:

We are using Garret Australia sourced GT28RS's in place of the HKS

GT2530's.

List:

Two GT28RS turbos

Two stainless manifolds suit low mount

Two dump pipes

Shipping

Delivery time will be aprox 10 days

Total is $6750

maby a highmount will be cheaper?

however i will need custom intake, dump/front pipe.. unless there is some sort of kit?

[JH32]

$6750??

You can buy a pair of GT2560's or whatever those popular ones are at the moment for less than $3,000 for the pair. I think "RACESPEC" on these forums was selling them.

Then you can buy a pair of X-Force stainless dumps for around $600. Think you can get these from Unique Autosports?

Is there much point in getting the stainless manifolds? I'm sure you can get to 340rwkw without them.

So for around $3,600 you can buy similar bits to what you enquired about locally, and have them now.

[JH32]

As for the high mount setup ...

Rough prices...

$1,500 to have a manifold made up

$500 for the external gate

$1,800 for the turbo

Couple'o hundred for the dump and front pipes to be made

[druzilla32]

yer i thought 6750 was a bit expensive

what decent single turbo could i get for under $2000

$6750??

Plenty of cheap singles under $2k

Once you add manifold, gate, lines/fittings, relocation of wires/hoses, heat shielding, fabrication of dump pipe, intake piping and any other bits and pieces it does get the cost up. Certainly not something I'd recommend doing if you're worried about the $.

To me a pair of GT2530s or similar on the standard manifolds makes the most sense.

keep in mind for that power you'll also need bigger injectors, afms and a ecu.

[druzilla32]

nah i was just saying that cuz JiMiH said $1800 for the turbo... i havent been able to find one that cheap.

i was planning to run stock injectors and ecu for a couple of months as the engine is being rebuilt now and i will just be driving it around softly on standard boost for a while...

but i plan to upgrade ecu and injectors...

also have bosch 044 pump ready to go in

[R31Nismoid]

get lowmounts.

less chance of hassle from anyone as most are swap over.

going a big single will workout to be around the same cost once you have everything made etc

[600hp]

GT-SS turbos with a 260 tomei cams and a 3.5'' exhaust.

GT2860 (707160-5). They can be had for about $2400 for the pair (see here).

Then you can buy a pair of X-Force stainless dumps for around $600. Think you can get these from Unique Autosports?

My 0.02c is that the X-force dumps are pretty expensive for what are just HKS copies, particularly if you want to change your front pipe too. Better off grabbing the Greddy Front Extension Pipes (~$1100).

Is there much point in getting the stainless manifolds? I'm sure you can get to 340rwkw without them.

Seemingly not. Have a search for the thread by John from UAS about his improved stock manifolds. Quite some discussion in there.

what about something like:

T70 (650hp)

- 0.70 A/R Compressor

- 0.84 A/R Turbine

I wouldn't be using a plain bearing turbo on a car that sees the circuit, OK on a drag car though.

Try Horsepowerinabox ... sometimes they have specials

http://www.horsepowerinabox.com/HPIAB2/category12_1.htm

GT35 for around $2100

Shop around you'll find something for around 2k.

[PSI_GTSII]

From my Experience so far Factory ECU does not like Turbo upgrades to much, Mine runs a pair of GT2560Rs, Trust Greddy Dumps and front pipe, 14psi and gets 315rwHP.

Runs extremely rich over 5000rpm, restricting power.

For me now to get 450rwHP (similar to your goal) I would require a PowerFC and some larger injectors (probably SARD 700cc) and some adjustable cam gears, add a more boost she'll hit 450

All up in parts alone you'd be looking at around $6500.
