Hi, Im Jake, im 19.

Recently i purchased this bad boy.

09052010.jpg

Its a 1987 Nissan Skyline HR31 GTS-X.

It has 126,000kms on the clock, and im stoked!

Runs a Redtop ECCS Rb20det, with a couple goodies, including a HKS 2510 turbo, GTR Intercooler, Malpassi Fuel Regulator, Fuel Cut Defender, BOV (needs removing), 3" Kakimoto Exhaust, Oil Catch Can, RB25det rocker covers, and a pod filter.

Suspension wise, it's got Pedders lowered springs, Pedders Shocks, and adjustable castor rods.

Rims are a set of 17x9 Stich Meshies for the front, and rears are the same, but in 9.5.

Paint is a custom pearlescent black. Basically, it's a 2009 Hilux black, with silver taken out..and a bit of sparkle/blue is added, looks pretty nice in the sunlight.

Exterior consists of a GTS-R spoiler and a modified GTR front lip.

Interior contains a CD player, Autometer Boost Gauge, and a Personal steering wheel.

Like every kid out there..i want this thing to have a rb26dett, full straight cut gearbox..yada yada yada, but no.

For the time being, im planning to get a NIStune, some decent spark plugs, Yellow Jacket Coilpacks, Coilovers, and a proper tune. Nothing over the top, but something that i can manage to keep me, my bank account, the parents, and the police happy.

Very nice :) Im running the redtop eccs motor in my oz spec r31 with a r33 sr1 turbo but looking at going hks 25/30 very soon. If your looking at getting your butterflys removed boostworxs will remove them for around $60 if you take the plate in.

Id put a set of redtop rocker covers back on :3some:

Cheers guys,

Didn't know many people still liked 2 door R31's!

Car currently does have some small things that need fixing.. seems to have a small flatspot at 3000rpm, but only in third gear..wether that is spark plugs, coilpacks, or something else, i plan on getting on to it.

Also, has a bit of detonation at 5000rpm. Again, it'll need a proper tune, this is where the NIStune will be coming in handy.

I'll most likely be giving Decs at Garage 7 in Adelaide the reigns of her, he's a good mate, and specialises in R31's, so i have no doubts about his abilities.

Being an apprentice diesel mechanic myself has it's benefits, a pit, quality oils, scanners and trade discounts at my disposal, i plan on making this thing run well..might enter a car show here and there, also, plenty of Track Days! My old automatic r31 loved it last year around Mallala, so this thing should do the same!

This was going to be my daily whilst the R32 went stoopid impractical but still slow spec :) Agree, a neat R31 coupe is a cool daily driver. Wish that prick never tee boned mine all those years ago, I would still have it! Only grabbed my current R32 because it was neat and and i couldnt find another neat R31 back in 99. Fark that was a long time ago :D

whats with the TRD wheel :P

NOT YOU TOO!

Everyone notices it!

I'm not exactly too sure why it's there. Probably going to get my Momo Typ 35 steering wheel re-trimmed, and a momo horn button fitted soon, so it really isn't annoying me.

Also, tonight after work i fit up a new set of spark plugs. NGK Iriduim IX's. The older plugs that were in there (Bosch Platinum's) weren't that bad looking, had the usual burn marks on the tips. The Bosch one's also had quite fat tips underneath the metal barb covering it, whilst these NGK's have almost a pin needle with end to them..can anyone tell me why? It seems to have fixed the flatspot i had also..strange things.

Ordered a NIStune today from Garage 7, and should be installed next Monday afternoon. Fuel cut defender will be taken out, because apparently it is useless, and just tricks the AFM and ECU into doing different things. Tune and Dyno time will be done shortly after.

I'm unsure what power it will make. I'm hoping 16-17psi daily. When i told Decs, that the former owner said it make 217kw on 18psi, all i got was laughter..i too have my doubts about this.

I'd like 180-190kw, on a pretty reliable tune, nothing silly, but enough to keep me occupied.

I'll keep ya posted.

Jake.

Small update.

Got Garage 7 to install the NIStune Type 1 liveboard this evening, tune should hopefully be done within 2 weeks, on a hub pack dyno, mainly for the accuracy of these units. Fuel Cut Defender was removed also.

Will also be doing the Garage 7 AU Falcon Coilpack Conversion.

Cheaper, and something different.

Got the car back today from Garage 7, and im extremely happy. Although Decs couldn't get it on the dyno today because of a small issue with another car at the dyno place, it should be done Monday.

I got the AU falcon coilpack setup done, aswell as a Bosch 040 fuel pump.

Decs has been fiddling with the ignition and fuel maps, and explained and showed me on the laptop, what it is doing, which im happy with..any excuse to get to know what my car is doing! There is no hesitation before the turbo hits boost like there was, and it just seems to run alot smoother than it did.

Bring on Monday's dyno time! Im not exactly too sure on what to expect power wise. I've been told 190kw, others 170kw..so i really am not too sure. Guess it depends what the injectors and AFM like.

      Have you done the Ignition Sync Wizard in the AEM software?

      R32 GTS (RB20DE) Injectors Replacement

      By MBS206 · Posted

      Find out what RPM it was idling at with the IACV unplugged. It's very weird that the rpm didn't change at all, and then it stalled. When it stalls is it nearly like a switch off, like you've turned the engine off? Or is it more stutters and sputters and coughs to death over a few seconds? Or does the RPM just slowly keep going down and down? Have you done a test of trying to start it with the AFM unplugged? Does it still die?     If you Follow Josh's advice on using Nistune to check the voltages (which is a perfect method!) if you see anything out of wack voltage wise, THEN get the multimeter out and read the voltage directly at the sensor. If the two vary, then you're now looking for a wiring issue vs a sensor issue. So be aware, what the ECU sees, may not be what the sensor is actually saying too...

      RB25DE NEO with Haltech ECU

      By MBS206 · Posted

      You very likely need to get it on a dyno and tune it. My assumption is, you've got an RB25DET tune in it, which has a different manifold, different injectors, and different cams as a minimum. What O2 sensor are you running?   When you say it runs extremely rich from idle all the way to redline, is this just free revving it you see that?

      RB25DE NEO with Haltech ECU

      By Haggerty · Posted

      I seem to the be only person that is using a Haltech 2500 on an NA motor, I've installed a Bosch DBW throttle body to the OEM intake manifold and am having problems maintaining AFR even with the wideband o2.  It will run extremely rich at idle and up to redline, but under load it will go extremely lean in the 20s and i'm essentially having to rev it over 4k and feather the clutch to get it up to speed.  I've read a few other threads of about the butterfly, it seems removing the vacuum to it is supposed to have it remain open, i've noticed no difference under 4k with the vacuum line to it plugged.  I'm hoping someone here has had luck using the NA manifold with Haltech, and if they happen to have a tune for it.

      Could it really happen......

      I don't know any details, but I really wouldn't be surprised if they do it as a LHD only version, at least initially.
