I'm seriously considering throwing some $$$ into my car.

Been doing a LOT of reading, and i've pretty much settled on this list of goodies.

Car at the moment has stock ECU and stock turbo/cooler, as in sig.

Engine appears to be healthy, it's just clicked over 100,000 and had all belts/pump replaced etc etc.

1) Z32 AFM ~$250-300 2nd hand

or $400 new Nengun

2) Genuine Hybrid FMIC with piping $800 autospeedbits.com.au (delivered)

or $700 no-name with piping justjap.com (delivered)

3) Apexi Power FC $950 group buy SAU

or $1050 Racespec

or $954 Nengun

4) Injectors SARD 550+ Collars $930 nengun

or Nismo 550 $890 nengun

5) Turbo GCG Hiflow $2000 [EDIT: now HKS GT-RS]

6) Beefy Fuel Pump *tick* Mk4 supra

7) Heavy duty clutch *tick*

?? 8) Fuel pressure reg eg $150 Nismo nengun

TOTAL $4050 + ?injectors + labour/tune

--> $5000-6000 complete, give or take a bit.

Bearing in mind i would be installing the PFC and FMIC myself, and then probably get it trailered to a shop with a turbo and injectors and get them to make it go :)

I want a bolt-on turbo without too much fussing around and i thought the GCG would be a good way to go for cost and ease of fitting.

a few questions for those that have done this before...

a) Will i need injectors? it seems that i will.

b ) Will i need a fuel pressure regulator?

c) Rough power - is 240rwkw reasonable or would 220rwkw be more likely?

and finally,

d) Would it be better to source parts and get them in, or get a shop to sort parts for me? I've heard so much conflicting information. I'm not set on getting "rice" name parts; they are just what came up on a quick price hunt for initial costing.

If i've left stuff out i'll try and add it in.

Thanks for your ideas/opinions/criticisms,

B

Im not in anyways experienced, but I dont think you'd require a Nismo fuel pressure regulator along with the injectors. Spend the cash and go injectors.

Also, search ebay for great condition 2ndhand 'name' brand intercoolers direct from Japan. Or a GTR cooler for $500 local with custom pipekit (again can buy a box of pipes off ebay and cut them to suit your application).

Sounds good though - I had a budget of 10k over 2yrs for my Stagea, already spent over 6k in 4 months! :)

Yep. If you're short on cash then a fuel pressure regulator will be enough to get you to 240rwkw but with enough money you might as well save the hassle and just go straight for the injectors.

Aftermarker injectors will be far more than enough for 240rwkw which you should be able to get with this setup :blink:

Thanks for the replies guys.

Yeah i've got mods both sides of the engine, and have the stopping/handling side of things fairly well sorted aswell.

Been thinking of getting some bolt-ons for the engine for a while now, and i finally (read: a few years!) feel i know the car's limits well enough to strap on some extra kilowatts :blink:

Never ordered through Nengun before, but through a similar site (Taka Kaira). I'd be expecting 2 weeks or so for delivery?

please read the sticky

http://www.skylinesaustralia.com/forums/in...showtopic=66556

mod order/suggestion threads are all covered in there.

only reason ill leave this open is you've given specific detail re: pricing and so forth.

here are some answeers for ya.

a) Injectors, dont need a reg, stock one is fine

B) Refer a)

c) 250rwkw, Bass Junky did with his GCG, but slightly different to normal one but around that you'll make, more than 220

d) PFC - get from nengun/greenline. Get a NEW Z32 AFM. 2nd hand ones cn be dodge and not worth the hassle

go for 740cc's as they are like $5 extra per injector from nengun.

and get nismo instead of sard no need for collar crap

make sure you have 3" split dump and 3" hiflow cat

and some good tyres as well. good cold air intake dont leave the pod unshielded

Okay after much reading and research and conversation i've decided on the HKS GT-RS. Good resale and i've read nothing but good reports.

Nengun has a package with PowerFC + 740cc Injectors + turbo kit, which i know a few people on SAU have installed in their cars already, with good results.

My concern is re: injector size.

I'm consistently getting told 550cc is plently for my needs. Having the overhead with the 740cc ones is fine, but a few shops have mentioned that the idle will be better with the 550cc ones.

The co$t between the two sizes is negligible

Does anyone have the 740cc injectors running, or know someone that does. any problems? This will be a daily driver battling peak hour traffic regularly so it is concerning :(

I've read every injector thread i could find and this issue is never mentioned. (maybe it's not much of an issue??)

I'm looking at getting this done in the next month(s) and will be sure to post dyno results etc for anyone else considering this path.

Cheers guys

I had them running in my car for over 8 months.

No problem what so ever

- direct fitting

- drove peak hour every day for about 4 months during that time also.

- idle was no different to stock (using a PowerFC)

You think the GT-RS isnt a bit of overkill for you though?

the GCG item is exceptionally nice and would be better suited IMO

^^Thanks, good to know.

I'm aiming for 250rwkw. Looking at track days and some advanced driver training with the car once it's all sorted.

GCG hiflow rb25det's seem to vary from 220(base)-260(with cams)rwkw from what i've seen, whereas GT-RS cars seem to be consistently pulling around 240-250, higher with cams.

I have a feeling i'd be a little disappointed with 220 if that's what i ended up with, is all.

Price difference is about $600 all up, with a stock turbo to sell/play footy with. Resale value comes into it too - IMHO the HKS will come out on top when it comes time to sell the car.

    • As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.  
    • It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack. 
    • Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.
    • In my head it does make sense to be a fuel problem since that is what I touched when cleaning the system. When I was testing with the fuel pressure gauge, the pressure was constantly 2.5 bar with the FPR vacuum removed. When stalling, the pressure was going up to 3.0 bar (which is how it should be on ignition).
    • ECUtalk pages don't mention they support the ABS computer (consult port has more than one CAN), so you might just need a different scan tool. But, I would expect ABS is a different light to the brake warning/handbrake light, do you see an ABS light come on for a few seconds when you turn the key from ACC to IGN? But since you said: I'd have a look at the ABS sensors in the rear hubs to make sure they are not damaged, disconnected etc.
