Opinions Please

[Beeble]

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!

Skip the fuel pressure regulator and go the injectors. I've read ppl having issues with the sards so I'd go the nismo for assurance.

If you're prepared to wait then ordering parts from nengun or the likes will be the cheapest way to go.

[rd-runr]

I'm assuming that you've already got a 3 inch turbo back exhaust. This should be the first!

[Trust33]

Yes read his sig!

[Dee 33]

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

[Beeble]

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

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

[paulr33]

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

[Beeble]

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

[Beeble]

^^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.
