GTR - Mods Help Stage 2 Upgrade

[meshmesh]

I'm going the next stage on the GTR & fitting some HKS GT2530's. But wanted some opinions regarding:

1. Injectors?

2. Fuel Pump?

3. Fuel Pressure regulator?

4. Anything else you can think of?

The car currently makes 270rwkw, & I'm considering going with the following items...

Confirmed= HKS GT2530's

Confirmed= HKS EVC 3 Boost Controller

Confirmed= Z32 AFMS

UNconfirmed= 600cc or SARD 700cc injectors? Noticed that some injectors need to be modified to fit, some need fuel rails etc etc.. No idea

UNconfirmed= Fuel pump Bosch 975, 040, 044?? No idea

UNconfirmed= Intercooler.. most likely keeping the stock unit

Currently, the internals are stock bar the Adjustable Cam Gears, & i have the following mods.

Power FC

Exhaust

Dumps=Stock

Front Pipes= twin 2.5" into 3"

Cat= Stock

Cat Back= 80mm

Once the upgrade is confirmed will I have any issue's with stock internals pushing above 300kw at the wheel?

You are following the exact route i had. I had no problems with going well above 300kw.

Nismo AFMs instead of Z32s.

Sard 720cc injectors, don't bother with the 600s.

Single 044 in tank.

High flow cat.

Stock cooler and engine.

Talk to Ben or the boys @ ICE, they will answer all the questions you may have.

Yeh, their doing the work me, rapt big time they're all awesome. Just wanted to see if others went this way..

Why Nizmo AFM's??

What sort of power are you making @ what boost?

With the 720cc, any major mods? does going bigger effect fuel economy "not that I'm worried coz I only get about 300 out of tank 70%hwy" just heard it stuffs idle & economy.

[Elithrar]

From what I know, RB20DET AFM's are 80mm and plug straight in.

I think the issue with anything larger than Z32 afm's, is the modifications required.

[Emre]

Why Nizmo AFM's??

They fit the factory airbox and plug into the loom without any modification. They are also brand new.

My dyno graph is in OZGTR's thread about the GTRS turbos.

They fit staright in the stock fuel rail. No different to 600s (or the factory injectors) when it comes to idle or economy, just a bit more headroom.

can u get the 330litres/min intank? didn't know these pump existed, or are u talking about the 230litres/mins 040 intank that has the guaze on the end of the tank?

[Emre]

hungry6,

Noone is quoting any flow rates.

meshmesh was talking about his fuel economy of 300km per tank.

i just fitted a nismo 280lt hour pump tp my r34 gtr.

same as factory.. fits in with no mods.. about 500 bucks but easy to fit no cutting or modding pipes and clamps etc......

should be good for close on 600hp i have heard....

sell your gtr pump for 200 to 300 and the nismo one is good value......

cheers...

Mark,

where did you get the pump from & what injectors are you using? did you end up sorting out PFC issue?

[markr34gtr]

got my pump from nengun..

using 700cc sard injectors.

problemb with my car was the immobilizer... its fixed now thank god.....

I heard the SARD 700's need some mods to be fitted.. what sort of mods? Reason is, I have an R33, & expecting my R34 GTR late this year, so I would prefer to swap my mods over from the 33 to 34 when it comes, & return the 33 "as" original as possible.

If u have that much $$ to splash around y not get a full twin kit with new s/s manifolds and something like twin 2835's, motec management, stock pump intank with swirl pot then the 044, 1000cc injectors, stick a 75 hp nos kit in there and some JUN internals, trust 9 litre sump, dog box.

Great Idea, not sure about the dog box though ...

[Guest INASNT]

u can afford it, just go for it

[meshmesh]

I was being sarcastic, about the dog box & your idea of mods.

u can afford it, just go for it

Like most, Im on a budget also, & have to be realistic.

[Guest INASNT]

if u can afford a r33 and r34 gtr u must have a few investment properties etc that u can mortage to built a monster engine??

[meshmesh]

Mark,

Thanks for the info about the SARDS. I Just found out that SARD are discontinuing the single spray & now have a Brass Pintle Cap Dual Spray in the 650cc, 700cc & 850cc for the RB26DETT. It apparantkey specifically designed fot multicams???

Do you think there's any real difference, coz they reckon rather than a large single spray the dual splits the spray, spraying it directly into its path?

[RB_26]

Interested in this, the Greenline site is doing a deal on the 700cc sards at the moment. These I assume are the singles? Also they suggest that some lubricant... is required to fit the injectors in the stock rail.. I think they go in but I gather they are a *tight-fit*

Good price for the sards tho IMO.
