Turbo, Ecu And Fuel Upgrades.

[l_uk3y]

Hey guys. Well. Its time to bite the bullet. The car is screaming for a tune after hitting close enough to the standard R33 gts-t Turbos limit. So after think about sending it for a retune. The little demon inside is screaming for me to do it properly.

After searching and searching through different posts i am yet to find any practical information for me to study. In basic I am trying to achieve approx 230-240rwkw (not heaps) But i want it to come on fairly hard and fast early in the rev range. Basically little a stock turbo on steroids. Something that will bolt straight onto the stock manifold. Of course im also unsure what brands/models are best for my application. So here is the question. What would you recommend for my street setup.

Budget $4000-5000

Turbo - (230-240rwkw, comes on hard fairly early, bolts in standard location)

Ecu - (Budget but providing good street level features, have no desire for hand controllers or screens)

Injectors - (that will do the job)

Fuel pump - (Direct in pump replacement, quiet preferred)

Everything else should be pretty much upto the task. Any help would be great. Probably working on buying all parts individually and taking it all into a Melbourne workshop to tune and install.

Cheers Luke.

Holy heck, your kidding right. Apologies for my rough edge, but there is plenty, oodles, mountains of information in previous threads that will easily answer your much much much much too common question. To the point that someone will just lash out and say "do a search".....as I'm guilty of in the past, but had good reason to.

Anyways, to the point.

Turbo: HKS 2535,

Or if your willing to try out a hybrid Garrett GT2871R or GT3071R converted to be a direct bolt on for RB20/25 try here http://www.horsepowerinabox.com/hpiab2/category12_1.htm

(I'm keen to see how these turbo's in particular size up.....wanna try it for me? haha kidding)

ECU: E-Manage ultimate would do you fine they're roughly $900ish, or for a tad more a PFC can be had for $1100ish $1200ish 2nd hand and its plug in.

Or you could just get a remap done, but for me I've found having a tunable ECU an advantage as the tune can be touched up upon request without the need of re-flashing etc etc. Remaps are generally worth $5-600 odd....sometimes less.....once you find someone to do it.

If you don't already have one you'll need a Z32 AFM.....$250.

Injectors: 550cc's would do you easily, but for not all that much more 740cc can be had for almost the same price. $1000.....they used to be $700 tops, but the outhouse exchange rates are really killing atm. http://www.skylinesaustralia.com/forums/In...amp;hl=injector

Fuel Pump: Tomei or Nismo, both drop straight in and you can't go wrong....anywhere. If you do there's something wrong with you.

Or go Walbro if you like a little bit of mucking around to fit it, but is cheaper.

Tomei $499

Nismo $495

Walbro $195 but its a universal fit, not model specific.

Everything used to be cheaper, but like I said....outhouse exchange rates. So this above may have blown your budget.

There you go, officially spoon fed.

If it were me and its pretty similar to what im doing myself.

Hi-flow turbo (GCG $2k) or bolt on GT3071 + oil and water lines ($2500ish) or Find a 2nd hand HKS RB spec GT2530, 2535, 2540 , Adjustable fuel pressure reg ($250ish inc. guage and fittings) too squeeze a little more fuel in if your on a budget or find some S15 SR20det Injectors ($300-400).

040 or walbro Pump

2nd Hand PFC ($1200ish + tune so say $600)

and that is pretty much your budget

Arrr that's right s15 injectors, I forgot about them. Get 6 of them and your laughing

[R31Nismoid]

Turbo - 2530/2535

ECU - PFC

Injectors - Stock will be ok with a minor rail pressure bump via a FPR (only situation id ever use one)

Pump - Bosch 984 or something, less than $200, easy fit

[Swiper the Fox]

ECU = Vi-PEC plug-in....the ultimate stright plug in ECU...does not have the missfire and return to idle problems that plagues the Power FC

[R31Nismoid]

Its only the GTR PFC's that have the intermittent missfire issue due to the software (mine does it about once every 500kms)

RB25's do not unless something else is wrong somewhere, unrelated to ECU.

Dunno what return to idle problems you speak of though, GTR and my RB25 PFC were/are fine

[DaveB]

Slightly OT... but when upgrading the turbo (GCG hi-flow in this case), how far out will the tune be - eg. how to drive it to the workshop once the new turbo's in? Pull the AFM plug and run it in limp mode?
