Inspecting An R32 Gtr, How To Tell If Any Rebuild?

Hey guys. New here. US resident, living in Florida. I'm taking delivery of my 89 R32 GTR next week. It's reported as being "bone stock" and visually appears to be so in pictures (and by report of the importer), but the service records are scarce. I haven't seen the car in person yet. It has 120,000 km on it.

I'm planning out my rebuild, and want to know if there is anyway externally for me to know if any parts have actually been replaced. I'd hate to order a new oil pump (or really any bottom end stuff) only to find out when I pull the engine that it already has an N1 pump, etc. I'm sure the most obvious answer is going to be to not order parts until I pull the motor, but it's going to be my daily driver and I can't really pull the motor with no parts and then order everything after its apart. Plus, I can't really afford the cost of pulling a motor just to put it right back in. Thanks for any input.

TL;DR: my car is reportedly stock...is there any way to know if oil pump or other parts were actually replaced, before pulling motor?

I was in a private message conversation with another user and thought maybe I'd post some of the relevant facts that I had explained to him, in case they help shed some light on my above post...

I'm hoping I'm a lucky buyer. I spent awhile trying to find an unscathed example and may have pulled it off. I had them do a compression test and it was normal (I'm still waiting on exact numbers just to check their work). HIKAS was never disconnected or blocked. No warning lights on. Reportedly no grinding in 3rd gear. No rust, no wear on seals. Obviously, I know that things that are too good to be true usually are, so I'm anticipating a few surprises.

Before going further, I should explain that my goals are to have a bulletproof/reliable car. I don't have a power figure in mind, but I can't imagine putting the money into it to reach 600 whp. So we're talking a fast, reliable build, maybe 400-450 whp (just a guess). I'm coming from the MINI Cooper world so all of these numbers are blowing my mind as it is.

My reason for bringing up the oil pump was that after reading all the issues, I figured I would prophylactically replace it before it had an issue. Was thinking an N1 pump with a spline drive collar from Supertec (with stock crank, presuming it's in good shape).

If I'm to tidy up the turbos, would it make more sense to just get new turbos (such as GT2530s) or should I just replace the ceramic wheel with a steel one?

Really appreciate everyone's time.

I would just wait until it arrives and give it another compression test to confirm its ok. A good look around the vehicle should help you decide if its in keeping with the alleged mileage. if there are no service records I would do a service including plugs and cambelt.

I haven't heard any reports of a successful commercially produced spline drive oil pump although a few people have made prototypes.

Plenty of people have got 400hp out of these without opening them up so if the condition seems ok just go ahead although you will need a new ecu.

If your aims are modest then when the time comes you may just be up for rings, bearings, crank collar, oil pump and new hoses and gaskets etc). Or you could go to town and spend another $10 -$50k no trouble!

You should really consider keeping it as a weekend type car rather then a daily driver.

You will appreciate it a lot more taking it for a nice squirt on the weekends rather than driving it at a fraction of its capability in the daily grind to work and back.

Thanks for the replies.

Yeah, for the time being I've got a MINI Cooper S. But it was my track car and I'm currently parting it out. Once it's back to stock, I'll be selling it. I've also got a Triumph Street Triple R. After selling the MINI, I'll probably get another car as my daily eventually, but I've got to give it some time or my wife may murder me haha.

Regarding the spline drive, Supertec makes them and seem to be getting really good reviews. Not a ton of people run them, but the few that have (positive reviews), plus their reputation, plus the fact that it's proven in other cars (i.e. 2JZ), make me feel it'd be a more solid choice rather than a wider standard collar. I don't like the idea of two flat surfaces being the only thing between my crank and a broken oil pump.

After discussing with some others, I may be doing exactly as you recommend and just working on all the other things that make it more enjoyable (interior, suspension, brakes, exhaust) and only do the rebuild once it's actually needed.

At any rate, I'm very excited. It's like a new frontier for me. Always exciting to switch platforms, but I've spent about 23513642346 hours trying to familiarize myself with these freaking cars ha.

If these are not commercially produced spline drive oil pump gears, so what is this?

i dailied my 32gtr up until now. its not hard to do if its a good car.

however im now modding mine more so its a weekender. simply because when you mod you break and you work on it/ wait for parts/ wait for funds/ break more shit/ rinse and repeat.

over 300atw and daily and 25 yr old race car don't go easily together.

trust me.

also. well done on the purchase. put picks up when you get it and get a build thread going when you eventually get bitten by the modding bug and weekend it.

also well done for doing the right homework and thinking about the things which need to be thought about

      R34 Skyline climate control unit transistor

      By sinn3r · Posted

      perhaps i should have mentioned, I plugged the unit in before i handed over to the electronics repair shop to see what damaged had been caused and the unit worked (ac controls, rear demister etc) bar the lights behind the lcd. i would assume that the diode was only to control lighting and didnt harm anything else i got the unit back from the electronics repair shop and all is well (to a point). The lights are back on and ac controls are working. im still paranoid as i beleive the repairer just put in any zener diode he could find and admitted asking chatgpt if its compatible   i do however have another issue... sometimes when i turn the ignition on, the climate control unit now goes through a diagnostics procedure which normally occurs when you disconnect and reconnect but this may be due to the below   to top everything off, and feel free to shoot me as im just about to do it myself anyway, while i was checking the newly repaired board by plugging in the climate control unit bare without the housing, i believe i may have shorted it on the headunit surround. Climate control unit still works but now the keyless entry doesnt work along with the dome light not turning on when you open the door. to add to this tricky situation, when you start the car and remove the key ( i have a turbo timer so car remains on) the keyless entry works. the dome light also works when you switch to the on position. fuses were checked and all ok ive deduced that the short somehow has messed with the smart entry control module as that is what controls the keyless entry and dome light on door opening   you guys wouldnt happen to have any experience with that topic lmao... im only laughing as its all i can do right now my self diagnosed adhd always gets me in a situation as i have no patience and want to get everything done in shortest amount of time as possible often ignoring crucial steps such as disconnecting battery when stuffing around with electronics or even placing a simple rag over the metallic headunit surround when placing a live pcb board on top of it   FML

      Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked...

      Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily.
