Hi all, i'm new to the forum and also new to GTR ownership, so thought I might share my new ride. It took me 6 months to find this car, but it was well worth it. I'm a mechanic and have owned 24 cars, mostly imports so I knew what I was looking for. Compared to most of the GTRs I had looked at this car is immaculate, with no accident history, no rust, has been well serviced, hasn't got a rattle or squeek in it, and has some tasty additions to boot!!

March '90 model

110ks (genuine as far as I can see, belt changed feb '03 @ 104ks)

Black

17' work rims with potenza g3s

HKS ball bearing turbos (I think 2510s)

HKS split dumps into full 3.5' system

HKS oil cooler and remote filter setup

MINES retuned ROM

Possible cams and/or adj. cam gears

Straight off the boat pulled 228kw at all fours in shootout at 1.2 bar, but it doesn't make that boost till 5500-6000 rpm even in 3rd gear.

I know it needs some form of boost control (has restricter removed)

but any suggestions as to why it takes so long to climb onto boost will be welcomed. My tuner also suggested it may have a full MINES built motor, as it is painted in a goldy/silver hue, apparently their colour. The compression of 160 accross all four, HKS gear, no oil leaks and lumpy idle may also support this idea.

Anyhoo, any feedback on my boost issue would be great, cheers!!

Sounds like a nice car.

You should probably ditch the mines computer and have the car retuned in for aus conditions.

My car just has exhaust, power fc and boost controller runs 1 bar, it makes 227kw at all 4 wheels so your car should make more at lower boost. If it was retuned it probably would.

160 compression across all cylinders is very healthy but if it was a rebuilt motor in the last couple of years then you would be expecting comp rating around 180. I think mines use a dark blue on their rebuilt engines.

I reckon get new ecu and electronic boost controller, have it tuned and that car should be apples. :P

2510's and lag till 5000rpm in 3rd doesn't sound right at all.

people with 2535 or whatever they're called don't even see that sort of lag.

from what I remember, the 2510's are actually smaller than N1's aren't they?

and people with N1's basically say it feels almost like stock but with much better mid and top ends

    • I am getting the same issue. Did you resolve it? I just got it after installing my new super coppermix and literally the same issue, new fork, new 18mm carrier, release bearing that came with the kit and replicated the exact same sound. 
    • If you like - I have the STL files so I can email em. There's a couple of gotchas (i.e the holes are not threaded so you might need/will need) to utilize some M3 melt-in threads for some of the points. However if you want to be super accurate, and are willing to remove your calipers and your SHOCKS it's a really good tool. You also might need to scale the part that measures the tyre width a bit wider. It defaults to a 7.5in tyre and I mean who is running that. Luckily with the magic of CAD this is very easy to rescale.
    • jeebus. glad you weren't under it while performing the stunt. Also thanks for the link to the wheel measurer, exactly what I needed
    • In the older stuff there were very significant differences 2wd to 4wd, for example Stagea had strut front end for 2wd and double wishbone for 4wd so it was not minor to swap. From poking around the 2wd v37, it *looks* like it might be more possible; some of the parts specifically have "2wd" stamped on them which suggests the platforms are more similar. You'd still want to start with a 4wd half cut to swap stuff from though. I'd suggest if you don't have a tune on the ECU you don't really need one on the trans either. Throttle mapping is in the ECU side (and you can always use a Roar Pedal if you want the throttle to actually respond to your foot), and really if you are happy with the stock power you probably accept the stock trans behaviour too....its all made to be "sporty" not racey.
    • So, updates. I have not washed the car since it came back from Tassie. I've driven it around a bit but not got around to actually sorting it out. I DID raise it because I cracked the rear bar leaving a hotel which was very distressing. Interestingly, the car drives more compliant now that it's raised a fair bit (5mm front, 15mm rear). Also noticed that my FR height was 10mm lower than FL. So that's now sorted out, too. I also bought this and had it printed: https://www.etsy.com/au/listing/1576422240/wheel-and-tire-fitment-tool-universal?ref=shop_home_feat_1&dd=1&logging_key=08f604d9fa4cc383550ba985e6ac85cd5cac7fbb%3A1576422240 Now, if I was smart I would have taken my brake calipers off to actually use this correctly but it was evident enough to me that in the region where the caliper was... there was nothing to hit suspension/guard/arm wise. So I'm going with "it'll be fine" after using the tool to hopefully very precisely measure the wheel clearance. Also while doing this, I had the very VERY bad idea of jacking one of the wheels/suspension arms up while the rest of the car was on jack stands. I did this to see how the arm would travel. This all was well and good until the car slid off the stands and went through a fence. So don't do that. Incredibly nobody was hurt and there was only minor damage to the rear bumper as the car didn't have far to slide, and had 3-4 wheels on it. The only damage turned out to be the fence itself which was easy to fix, and a little bit of damage to the fibreglass rear bumper trim. I had already planned to try a touch up paint kit to fix the time I drove into my garage door to see if it'd help in the interim before I get it fixed properly. I used the Dr Colorchip kit after looking online and seeing everyone talking about it. Yes it's made for chips and not huge broken missing pieces and I'll be 500% recommending it for stone chips after using it for stupid things like me. This took about ... 10 minutes and looking at the half assed photo the 30 second job I did on the bumper corner was almost perfect just by using the tiny little brush and painting it in. The sealact stuff to remove over-painting is really useful, so if/when I do it again I'll likely slather the touch up paint well over it and then clean it up with the cleaning solution. The wheels should arrive in a couple of weeks. I am still kinda confident after doing a stupid amount of measuring (and borrowing a set of 18x10.5+15) that they will not fit because I overlooked something, somehow and flew too close to the sun. ALSO R34 GTR guard liners do not fit on a GTT. I bought the undertray brake duct guides and had the wonderful problem of them not fitting my intake, my oil cooler and the liners themselves were even worse. Attempting to fit them won't work in general - You would have to cut them up as another poster mentioned as the bodywork is different on the GTT. At least I can try to resell them. So instead of cutting those up, I cut up my old already-cut-up GTT liners and extended them by using some PP plastic and drilling some 8mm holes for some nissan clips for the 'extra' bit. Because I was happy to cut them I was able to mount them pretty damn forward so I now have some semblance of guard liners, and the brake vents seal the bumper from the bottom. It sort-of-looks like this, to give some idea - If you look at the GTR and then the GTT this is when I realised that I needed to seriously measure as the inside of the rim area is entirely, entirely, entirely different and could not take any internet measurements for granted.
