Hi guys,

I will be getting my HKS GT2835 Pro S from JPS for $2650.00 inclusive of delivery and taxes very soon and I just wanted to know what's involved in fitting it.

Know I know it is a direct bolt on to the T3 flange, however, I need to know how much a new 3" dump will cost me, new cooler piping, and new intake piping.

Am I correct in saying that:

A new 3" custom dump will cost me about $200

The cooler piping will cost me around $150 (as it doesn't bolt on to the standard one)

And the intake piping will cost about $100

Am I correct in making these assumptions?

Also, how long would it take an experienced mechanic to take of the standard turbo and put the HKS GT2835 Pro s (the mechanic charges $88 an hour, this is why I am asking so he doesnt rip me off)

I hope I am making a wise decision in getting the HKS GT2835 Pro s rather than the GT-RS..... what do you guys think, is it a better turbo in order to acheive 260 rwkw?

I should be hitting 260 rwks with the below mods and the HKS GT2835 Pro s should't I?

I got the following mods:

Straight through 3.5” exhaust

GReddy front mount intercooler

Cold air intake with pod filter

Power FC

Splitfire Coil Packs

Nismo 555cc injectors

Bosch 040 Fuel pump

Currently putting out 202rwkw on 13 PSI on a VERY safe tune

Any help will be much appreciated.

If its the complete kit you wont need much at all. If you are running the std turbo and dump pipe at the moment all the exhaust and cooler pipes will fit on with nothing needing to be changed apart from the pipe from the air cleaner. This is because the mouth of the turbo is bigger. It should be eaisly fixed with a silicone pipe.

Double your estimates and add some.

You haven't included the oil and water lines.

The kit's aren't exceptionally good value, you could reasonably reproduce whats in the kit for about 200 less if you do your own running around and fabrication, but if you can't, then it's custom work and that costs money.

I would have bought the kit for the extra 900 just to save hassle. Then it will just bolt right up and you have all the little adapters and short studs and nuts, oil and water lines, intake pipe, silicone bits, dump.....

but yes, for 260-270rwkw the 2835 is definitely the turbo to have.

adz, the dump pipe is not a bolt up. the hks turbine housings are a special bit of gear and don't match the Nissan flange.

So the kit you speak of includes a dump (which I will have to get the front pipe flange changed), and an intercooler adapter?

Maybe I should go the GT-RS, It comes with all the lines, gaskets nuts etc...???

I am just not a bit fan of the GT-RS, people with aftermarket cams have only seen about 250 rwkw, which is pretty crap if you ask me for a $2600 + turbo.

the kit is designed to hook up to all the standard piping, both intake and exhaust. If you have a one piece front and dump pipe you will need to remove it and just get a normal replacement front pipe. the hks dump has the right flange to bolt up to a standard front pipe.

I've installed one and it's honestly a dream to work with.

But, you are paying for it. A kit at the moment is roughly 3300 on nengun delivered. A gtrs kit is cheaper as it uses the standard outlet flange so your existing dump can be used and it has a standard size inlet flange so your standard intake pipe can be used so it's about 400 cheaper straight away. Still needs lines and a few adapters for the hot side piping though.

Not unless they've altered the dump. (my experience is 2 years back)

The HKS dump is quite short, only comes halfway down the firewall so you then need an exhaust shop to fabricate something down to the cat.

No dump to turbo gasket was available.

The intake side of the kit was designed for a pod setup. You can persevere and use the stock airbox but it's pretty tight in there.

The water cooling pipe from across the rear of the block is just dreadful.

It's about a 4-hour job, but the mechanic may find missing/broken manifold studs so ...........

You haven't mentioned which housing you intend buying, the 0.68 or the 0.87.

There's another decision for you.

Are you buying the turbo or the turbo kit.

if you have bought the kit it will come with; turbo, oil and water lines, hks dump pipe (will bolt upto the stock setup, same length as the stock dump pipe), intake pipe and air filter, small elbow that connects the turbo to the intercooler piping and hks heat shield.

so you don't need anything at all.

but if you just bought the turbo itself you will need to have a dump pipe made up as the flange on the turbo is a one off design by hks and very difference to the stock design.

you won't need oil and water lines as the stock lines will boltup to the turbo, you will need to fab up an elbow to connect the turbo to ic piping. also fab. up a intake pipe as the stock one won't fit.

NOTE: THERE IS NO NEED FOR A Turbo -> Dump GASKET! HKS has design the turbo and dump pipe so you do not need a gasket, i have been runnning mine for 2years now without gasket and it is perfect :) (note i got incontact with hks in japan, from the help of a person there and they told us you do not need a gasket)

The turbo only comes in one size in the kit, but if you just buy the turbo by itself you can pick the rear housing size.

I was after the 0.87 A/R as is it a little bigger, thus more top end power ( but yes, a little more lag),

Is the the turbo that comes with the kit the 0.87 or the 0.68?

Also, if I did choose to get the 0.87 and decided to run 16 PSI, at what RPM do you think it'll hit full boost (ie 16 PSI), no more than 4,000 I hope...??

Also, is the actuator adjustable on the GT2835 Pro S?

And finally, is there a big difference between the 0.68 and the 0.87? Someone wrote that they got 12 rwkw less with the 0.68...

Also, I can't seem to find the complete kit anywhere apart from greenline, selling it for $3518.00 AUD delivered including taxes, however, it is not specific on what the kit includes...

Is it just the lines and gaskets, or does it come with the dump and elbow for the cooler?

It would be much appreciated if one of you guys could send me a link to a seller that sells the whole kit so I know what I need to get.

Also, a shop bd4s performance in Australia offerred me the kit for $3,700, is this too much?

0.68 or 0.87... is there that much diff?

the kit comes with the 0.68 housing.

you should see full boost under 4000rpm even with the larger housing. i get full boost (16psi) @ 3200rpm with the 0.68 housing and im running stock cams.

yes the actuator is adjustable.

not sure about your last question

the kit comes with the following items:

HKS Turbo

HKS adjustable actuator

Braided water and oil lines

HKS split dump pipe

HKS heat shield

HKS intake pipe (turbo to airfilter pipe)

HKS air filter

Elbow (to connect turbo to i/c piping)

Gasket (turbo -> mainfold)

silicon hoses

Clamps

i see if i can find a photo of the kit, for you

I would check that greenline includes the Australian import taxes before you make the decision. For a street car, i would also recommend the smaller ex housing, in 90% road situations it will be better. The .68 may make 12rwkw less at 7000rpm, but ill bet it makes 20rwkw more at 3000rpm.

greenline have the whole kit for sale (HKS GT2835 Pro S):

http://www.greenline.jp/catalogue/bccatpar...category=engine

Cost 277,000 yen = $2880

Shipping 13,000 yen = $135

Tax is $144 (2880x 5%)

GST is $315 ((2880x5%)+2880+ shipping)x10%

Total is $3,474.00 inclusive of all taxes and delivery.

Now, I am not implying anything, but I am sure you know alot of these sellers mark their goods as gifts, thus, avoid tax.

Hence, I could get the product $459.00 cheaper...

Does anyone have a dyno graph of someone using the HKS GT2835 Pro S with the 0.68A/R? Will I still be able to make above 260rwkw with the 0.68?

Thanks for your responses and help.

i made 251rwkw @ 16psi with a very average tune (11:1 afr - very very rich) and stock cat.

so 260rwkw doesn't look that hard for 0.68ar

Edited by [Michael]

Mine made 260 on 15psi, would of made more easley, but I didnt want to push the standard internals.

I do have cams though.

The people I talked to about this said go the 0.87 housing on an RB25DET , its supposed to spool not much higher than std though it'd need to be tuned properly . Also I'd be doing something very soon with the cat because the compliance type are not exactly a free flowing item . It would be a shame to fit a 3000+ kit and choke it up with exhaust restrictions .

Someone here supplied me with a direct fit 3" Catco and the difference was quite noticeable - and that's with a std turbo and a quiet Nismo exhaust .

Also it may pay you to ask around and see what people think about the 3037 Pro S with a 0.68 A/R turbine housing . I haven't found anyone using this combination on an R33 but their feedback would tell you if it was a little laggy or not .

A bit of homework pays off , cheers A .

if your into hero dyno comps then 12 rwkw at 11ty billion revs is great...

BUT if your into hero dyno comps you dont buy a 28series turbo...

go the smaller housing and have a more enjoyable street car

Ive got a .72 rear housing for a 2835 Pro S im looking to get rid of if your not really wanting to go as far as a .87

Im sticking with the .68 as the turbo is going on an RB20 not 25

Let me know if your keen... Or anyone is keen
