Hi all,

I've been reading up on your forums for a while now and figured it's time to make an account. Pretty awesome there's decades worth of (English) consolidated information on the R chassis, simplifying the ownership for newer American owners. I've had my R32 GT-R for about 3 years/7k KM now, and it's currently California emissions complaint(PITA). It's pretty much my weekend therapy cruiser.

Before the car was reverted to a CA legalized state, there was several aftermarket parts removed but, quite frankly, unknown parts may still be on the car. Before I bought the car, I was able to drive it once in it's modified/tuned state. Based off the powerband (~4.5k RPM peak boost), installed F-Con/EVC/HKS actuators/Sard 800cc Injectors, and spiked factory boost gauge, I think the turbos may be aftermarket. Butt dyno felt like 375-400whp. More on that later. Here's the configuration when I bought it: https://www.importavehicle.com/vehicles/363/1992-nissan 

So, the true joy of Skyline ownership is beginning with some gearbox noise independent of RPM. I'm assuming throw out/thrust bearing over input shaft since it's a relatively consistent cadence and noise level. Either way, the box is coming out and I'm going to the drawing boards for a minor refresh project since "I'm already in there". I'm 99% going with a Nismo Twin non-competition model. There's a small chance I have a twin disk in it right now based on the floating disk chatter, quite forgiving engagement though.

Aside from addressing the clutch/gearbox, I'll be inspecting or considering upgrades for the following areas:

1. Inspect turbos while front pipe/transmission removed. Hoping a quick inspection of the exhaust wheels show they aren't ceramic, or I'll look for serials/codes.

2. Reinstall turbo back system. Already have the original RSR equal length (2x70mm to 80mm I think) the car came with. Will be buying a high flow cat (76mm) and likely a Fujitsubo exhaust (76mm). Not only do we have emissions issues here, we also have sound ordinances in some cities. I prefer a quiet-ish exhaust and not going for big power, so all good.

3. Replace coilovers. They ride like crap because of age and spring rates. A lot of the recommended brands you guys use aren't available here, like MCA, so I'll probably open a new thread to get some guidance.

4. Upgrade/refresh suspension components/bushings.

5. Basic engine health check. Compression, leakdown, leaks (if any), belts/hoses, etc.

6. Fluid flush, brakes, other misc. services.

6. Reinstall or buy injectors/buy new ecu and get tuned. No true power goals, just want it safe and flex fuel wouldn't hurt (it's $3.19/gallon for E85 vs $6/gallon for 91oct/95ron).

I have my work cut out for me. It'll be a lot of parts gathering and planning before I start working on it. Look forward to researching for my upcoming project.

Thanks for reading

Welcome to SAU, it looks pretty tidy!

Thanks. It's not quite nice enough for a museum and not quite rough enough for a lawn ornament. She may get comfortable on jack stands for a while though. lol

Just contact MCA. Paying in proper dollars should reduce the pain.

I'm not terribly worried about the buying from them, but I was more concerned about post-purchase aspects like servicing and support without sending them back to Australia. Their dealer page doesn't have any North America listings. I was planning on working with a shock builder to assemble/valve to my use case, but I'll send them an email to see if they have servicing partners in the States.

I wouldn't worry about that. There would have to be clever suspension shops in the US that could disassemble and service the dampers (with internal parts from MCA if required) if required. But I would put money on the concept of you not needing any such service. Even assuming a generous 10000km/yr mileage, you wouldn't wear them out before the heat death of the universe (read that as petrol costs going to $10/litre).

The center section somewhere should have a part number/tag if it's a Garrett/OEM turbo, the compressor housing is another common spot for turbo specs if it's aftermarket. If you look carefully you should be able to spot it without any disassembly. Easy way to tell whether your stock turbos have had steel turbines installed is look at the exhaust turbine retaining nut. A ceramic turbine will have many sides/splines, aftermarket is usually a standard hex or something similar. I just helped a guy identify his turbos after he blew his motor. Seller claimed it was "Garrett GT2860RS" which should've been a red flag considering those are not direct fit for RB26s. Pulled off the engine it was clear it was R33 ceramics with a metal turbine rebuild kit.

I got a response back from MCA. Between the international warranty policies, shipping costs and import duties, it washes the exchange rate advantage of my Freedom/Reserve Currency compared to US company pricing. If they need to be sent back for any reason, I would be uncomfortably close to my preferred choice (such as MCS 1WNR ~$6k AUD). You serious about floating me some money if things go sideways🤣

We do have countless boutique suspension shops for service on pretty much every premier brand which is great. Several being less than an hour from me. It's not a 100% no for MCA just yet, but I'll be inquiring with several other companies before making a decision. I may take a 2 phase approach to coilovers and buy a "holdover" set ($2.5k AUD) so I can allocate/reserve more funds toward other harder to replace items (turbos, bushings/mounts, etc.). I also wouldn't mind a cheap second set so I don't have downtime when rebuilding the primary set.

Thanks for the heads up. I have read about the exhaust turbine retaining nut identification before, so I figured since I'll be way down there for the transmission drop, it'll be a 5 minute borescope colonoscopy. If that proves inconclusive, I'll definitely look at the compressor side. I'll be honest, while I'd love if the car magically has a set of garrett -7 or -9 on it, I'll be plenty happy with any non-ceramic set.

That sucks about the seller pulling a fast one. Assuming it was tuned properly, the power delivery would have been a red flag, no? At least he can sell them to someone who needs a stop-gap for ceramics and he can recoup some cost towards his desired upgrade.

Car looks neats, good luck with it! 

 

 

LOL one financial death at a time. Thanks, I appreciate it.

I actually just paid for a carvx report and found out more about the hidden parts installed on the car. Probably should have done this earlier.

1. HKS GT-SS turbos (same as Garrett -9s): I'll visually verify, but very happy about this.

2. HKS cams: Doesn't say profile, I'll open up the covers to verify what I can

3. HKS fuel pump (280L): Will I max this out with E85 on GT-SS/-9s? I've seen mixed on this through other threads.

4. OS Giken clutch: I can't read the model; the writing is messy after "OS Clutch". I might hold off on the Nismo twin if the OS Giken is a twin and current model for rebuilding. I found the clutch very easy to drive in traffic and on hills.

It was not tuned properly, the turbos also blew up. So he just has some possibly rebuildable cores basically. For some reason there was RTV on the compressor housing instead of the correct OEM gasket. Details like that are the reason why I told him he needed to tear down the whole engine and do a nut and bolt rebuild the right way. He never showed me the center section gaskets but anyone willing to cut corners like that probably also put RTV on those gaskets or just used RTV which is probably why his turbos blew up to begin with followed by his bottom-end.

I recommend no matter what the provenance of a car to always be skeptical and when you do have a chance verify things were done the right way. Someone willing to cut corners almost never stops at the small things.

Wow, damn. If I saw clues like RTV in places it shouldn't be, on top of disclaimed turbos, that's definitely the prudent approach. There's a good chance that even if my engine comp/leakdown is clean, I'll probably still borescope the cylinders to see how it looks in there. No leaks in my garage and dipstick reads perfect between 5k KM oil changes. With how expensive everything on these platforms has become, why not add a bit of insurance when possible.

I would skip the HKS fuel pump and go for an integrated system of pump, lines and injectors to switch over to E85

Wow, didn't think I would need something that extensive for my power level, but looks really nice. I wouldn't mind a setup that I could grow into if I go down the path in the future. I think at this point I should start a build thread to gather all my thoughts in one spot for feedback. 

So essentially you have a 30 year old car, that has had all sorts running through the fuel tank and into the lines and filters

 

E85 will clean the gunk off all those surfaces and send it straight to your injectors.

 

So a E85 fuel pump, lines, fuel tank clean and ensuring your injectors are up to the task is essential for happy motoring on E85.

    • Thanks for all the replies fellas. Gonna finish putting it back together and see how it handles the set up. If it starts pinging it’ll be parked.
    • Well, I can recommend the partial AV system translation CD I ordered from Car Audio Workshop in NZ. Whilst it didn't address the date issue, it has conveniently translated on-screen menu items into English, and now allows the GPS-received time to be offset in hours rather than minutes, so I can display Eastern Australian time accurately ( and bump it by another hour when daylight savings starts ).
    • Yuh, if it's 45°C outside, my car is driving in it.
    • I'd be curious to hear more. Otherwise, have you driven a modern x-trail? I wonder how it compares. Here in Australia they are/were popular for rentals and fleet vehicles. I have been in some and my impression was they are bad. But, this may have been very different in the 2000s at a good trim level. Twenty years is plenty of time to make the model worse. I do very much agree with the 2 silver cars in the garage approach. But, not driving because it's too hot would not leave a lot of time in the year for many Australians. I don't think you need to worry too much unless the car has actual issues with overheating. 
    • Back again. I returned to Japan in Jul/Aug to spend time with the car on my birthday and remind myself what all the sacrifice and compromise is for. It happened to line up with the monthly morning meet in Okutama, which I have been wanting to go to for a long time. It's a unique event at a unique spot with really rare, interesting, and quirky cars. It's where all the oldheads and OGs gather. The nighttime scene at DKF certainly has its place and should be experienced if you're into cars, but there's too much bad attention and negativity around it now. IMO the better time is Sunday morning at DKF or Okutama; it's more chill and relaxed. I'm glad I was finally able to go, but not sure it's worth the drive from all the way from Nagoya immediately the day before, unless I was already staying in Tokyo for the days right before the meet, because you have to wake up quite early to make it in time. Funnily enough though I didn't drive the car all that much this trip because it was just too damn hot. While there were zero issues and running temps were nominal and the A/C was strong, RBs already run crazy hot as it is. Sure, it took it all like a champ but something about driving these cars in the ridiculous heat/humidity bothers me and makes me feel like I'm asking too much of it. I'm just me being weird and treating the car like a living thing with feelings; I'm mechanically sympathetic to a fault. Instead I was mainly driving something else around - a KX4(silver) 2001 X-Trail GT, that I acquired in May. There's a few different flavors to choose from with Xs, but visually it's the Nissan version of the Honda CR-V. Mechanically it's a whole different story as this, being the top-trim GT, has an SR20VET mated to a four-speed auto and full-time AWD! It was a very affordable buy in exceptional condition inside and out, with very low mileage...only 48k kms. Most likely it was owned by an older person who kept it garaged and well-maintained, so I'm really happy with how it all worked out. It literally needs zero attention at the moment, albeit except for some minor visual touch-ups. I wanted something quirky, interesting, and practical and for sure it handily delivers on all three of those aspects. I was immediately able to utilize the cargo and passenger capacity to its full extent. It's a lot of fun to drive and is quite punchy through 1st and 2nd. It's very unassuming -in the twisty bits it's a lot more composed than one would think at a glance- and it'll be even better once I get better tires on it(yes, it's an SUV but still a little boat-y for my liking). So...now I have two golden-era Nissans in silver. One sports car and one that does everything else; the perfect two-car solution I think👍 The rest of the trip...I was able to turn my stressed brain off and enjoy it, although I didn't quite get to do as much as I thought. I did some interesting things, met some interesting people, and happened into some interesting situations however, that's all for another post though only if people really want to know. Project-wise, I went back to Mine's again to discuss more plans and am hoping to wrap that up real soon; keep watching this space if that interests you. Additionally, while working in the tormenting sweatbox that is the warehouse, I was able to organize most of the myriad of parts that my friend is storing for me along with the cars, and the 34 has a nice little spot carved out for it: And since it can get so stupid hot in there, that made it all the more easy -after I was standing there looking at the car and said 'f**k it'- to finally remove all the damn gauges that have mostly been an eyesore all this time. Huzzah. The heat basically makes the adhesive backing on the gauge mounts more pliable to work with, so it was far less stressful getting this done. I didn't fully clean it up or chase the wiring though; that will happen once I have the car in closer possession. Another major reason to remove all that stuff is to give people less reasons to get in my car and steal s**t while it's being exported/imported when/if the time comes, which leads us to my next point... ...and that is even though it's time in Japan is technically almost up since it's a November car and the X would be coming in March, I'm still not entirely sure where my life and career is headed; I don't really know what the future looks like and where I'm going to end up. I feel there's a great deal of uncertainty with me and as a result of that, it feels like I'm at a crossroads moreso now than any point in my life thus far and there are some choices I need to make. Yes, I've had some years to consider things and prepare myself, however too much has happened in that time to maintain confidence and everything feels so up in the air; tenuous one might say. Simply put, there's just too much nonsense going on right now from multiple vectors. Admittedly, I'm struggling to stay in the game and keep my eyes on the prize. So much so in fact, that very recently I came the closest I ever have before to calling it quits outright; selling everything and moving on and not looking back. The astute among you will pick up on key subtext within this paragraph. In the meantime I've still managed to slowly acquire some final bits for the car, but it feels nice knowing there's not much left to get and I'm almost across that finish line; I have almost everything I'll ever want for my interpretation and expression on what it is I think an R34 should be. 'til later.
