Hks Gt2835 Pro S -built Up R33

[Kaido_RR]

Hey,

I was just wondering if I have everything I need to put my new turbo on my car and also any advice with the max level of boost I should be running etc..

Current Mods:

Hks Cat-Back, Trust Front pipe

APEXi Filter

Tomei Fuel-pump

Greddy Profec A EBC

FMIC (chinacopy)

D2 coilovers

Heavy Duty Clutch

17inch rims with Potenza GIII 235

Parts on there way/Not on the car yet:

Nismo 740cc Injectors

PFC

Z32 AFM

SplitFire coil-packs

HKS gt2835 Pro S kit (hks dump, hks induction kit etc etc)

Here come my question

-Do I need a Fuel regulator?

-I was thinking of adding a Tomei Head-Gasket to the list to lower the compression and maybe a manifold- I have not been able to find a good low-mount, non-gate manifold for the rb25 (is this needed or can I do it later?)

-What is the safety max level of boost I can run before I starting putting excesses stress on my engine?

-Would aiming for around 300-330rwhp and a safe (rich) tune be the go to keep my engine alive?

-Once I have install the PFC + injectors + z32, is there something I must do so that I can drive the car to get tune (e.g. what do I setup on the pfc so the car will go)

Any other input, would be much appreciated

Thanks Michael

1) stock fuel reg is fine

2) get one made then, but its not something you "have" to get

3 & 4) Not a question of boost really... 260/270rwkw is generally accepted as the limit for a stocker motor. Your 240rwkw/330rwhp is easily safe, just get it tuned right and your fine. Doesnt have to be overtly "rich" or whatever. Just a solid no ping tune.

5) ugh... search button there. Few settings you'll need to change i think, its been covered before by someone doing the same thing... but stuffed if i can remember when

Should be a solid street package. Very responsive to drive indeed

[R31Nismoid]

Oh, also other things

if you get a chance measure pressure drop before/after cooler.

Just incase the china copy is a little dodge

Measuring the pressure will show-up if its a restriction right away.

you wont need splitfire coils unless yours are stuffed. Save the cash and buy them when yours die, they could last another few years

nismo 740's definately gonna flow enough, 555 or something would be better as thats all you'll need with that setup

[Kaido_RR]

thanks Nismoid,

well do the search about the pfc

My coilpacks are dieing, im running 0.4gap on my spark-plugs and if i boost above 0.6bar, i get major missfire :S

I through the nismo 740cc injectors may be overkill by they are like only 4000yen ($55) more than the 555cc , so might as well

thanks again for the quick and very helpful reply

[paulr33]

be sure to get your suspension and tyre setup looked into as well, with that sort of power you will certainly fry tyres with stock camber setup. the result is in the inner 10cms of tread bald and outer 15cms perfect traction left, as when you dump it the rear end squats and the tyres will sag inwards and only wear on the contact area. will result in quick tyre wear and only utilising say %50 of tyres width

[wolverine]

why not save the $55 the 555cc are more than enough for that turbo.

paul is giving you good advice why not take it...

^^ you should probably have a read of that thread, too.

A quick (but related) question - i too have 740cc injectors about to go in, they are waaay overkill for my setup i know. i mainly got them as i know i'll get a larger turbo one day soonish.

what are the adverse effects? some shops are telling me the idle and low-load economy will be suffering. and a few others say it's not a big issue. hrmmm........

[R31Nismoid]

i was using 740's also

i had no problems. Just saying if he hasnt purchased them, or thought there were "needed" that they arent.

But are good insurance, and stuff all extra if you plan on going bigger later on

My idle with 740cc/PowerFC was exactly the same as stock. YOu'd never know it has 740's in there. Fuel economy was a little worse, but then i had changed to a larger turbo than what i had among other things so for me economy i would say was fine.

Anyone who says you will have problems with idle doesnt know what they are doing, and i certainly wouldnt be taking my car there if they cant get something simple like that correct.

cheers -ash

Thanks Ash. That's reassuring to know.

My car is getting Racepaced in a few days, so i'm not terribly worried. Excited, though - yes! looking forward to seeing what my humble GTRS is capable of...

if its going there, you have nothing to worry about

i might see your car there, ill be out there at some stage

[Kaido_RR]

just an update

pfc, afm and injectors are need..

waiting for my gasket from hks, should be here in the next few weeks then its off to the tuners to hopfully smash out a 350rwhp on a tied old rb25 with 100,000km+

also looking to install my antilag system this weekend if i get the time

[R31Nismoid]

Excellent

Make sure you post results here, and in the dyno upgrade sticky

will do

here are some pics of the antilag for the people that are interested: http://www.skylinesaustralia.com/forums/in...5entry2125145

[grigor]

2835 Pro S doesn't need anti lag. What it does need is money spent on the wastegate/boost controller.

You'll never need 740cc injectors with that set up either, 555's are heaps.

Go for a drive in a 2835 equipped car before you spend the dollars.

Traction and boost control are the 2-worries, certainly not lag.

I have HKS 2835 Pro S in my R33 GTS-T.. with PFC + 740 nismos, plasmaman FMIC + plenum, etc.

I invested in Turbosmart e-boost2... these are excellent.

I'm getting TEIN type flex coilovers + Kaaz 1.5 way LSD to fix the traction problem...

Yes, you'll absolutely love the turbo.

[Busky2k]

I cant see how coilovers will help traction. Getting a set of camber arms (or bushes) certainly will though.

[Color_Of_Green]

Busky2k: are you saying that they wont help at all?

awsome, how much power are you making?

im going to get a 2way Kaaz lsd very soon, as i use the car for drifting and well the stock lsd just wont cut it i think hehhe.

ohh and i found coilovers made a heap of difference to my handleing

[Color_Of_Green]

At a recent dyno day @ UAS, it made 268.3 rwkw @ 17psi

Although I am no suspension expert, the stiffer springs and shocks can reduce the weight transfer upon launching ie less rear squat. But its not a dead end for sure, getting the correct camber, toe and tyres can affect traction in a huge way.
