Advice On Early R32 Rebuild

[ltjpunk7]

So, another question. After spending more time with the car, not unexpectedly there are some transmission issues. There is a relatively loud whirring noise whenever the clutch is not engaged. Whenever I engage it (push the pedal down) the noise goes away. Is this the throwout bearing or input shaft bearing? Also, there's some minor grinding in third and fifth. Assuming synchros there. My question would be where to go from here. Would it be reasonable to pull the clutch and check out the bearing or with the likely Synchro issues does it make more sense to do them both at the same time? Or should I just replace the clutch given that it has 123,000 km? Or is this all stupid and does it make more sense to try to find a newer gearbox? Appreciate any input. Was about to do a fluid exchange, but figured I'd make a plan first so I'm not just wasting that fluid. Thanks.

just drive it. put some good oil in the box, like redline, and don't hammer the shit out of it.

address the bearing noise when the clutch gives out. address the box when you have enough power to kill it.

whatever you do, prioritise your money or prepare to spend allot very fast. eitherway the car will tell you whats more urgent when things break.

Ok. Yeah I already purchased Redline fluid in preparation for that, I just wanted to make sure this wasn't a bad idea to just replace fluid, or that I should def be doing x y or z. So I'll just sit on it for now. You're right, this car can go from zero to money pit very quickly.

Sup mates.  So, some updates.  Did most of the rebuild in May 2016.  Current status is:

• Whiteline suspension bushings all around
• Whiteline sway bars
• Nismo front strut brace
• BC Racing coilovers
• Ride height and alignment done pretty close to Gary Cook's specs
• Whiteline HICAS delete
• Goodrich braided SS brake lines
• G-Loc brake pads
• Z32 brake master cylinder
• Cosworth intake filter
• HKS Silent Hi-Power exhaust
• Mines front pipes
• Decat pipe
• All vital fluids and a lot of eroding rubber hoses and fuel lines replaced
• Nismo Super Coppermix twin plate clutch / lightened flywheel and tranny rebuild with new center plate and synchros in 11/2017 because of synchro and clutch failure.

I also have a few random parts at my ouse that I've purchased over the year whenever I got good deals on them.  These haven't been installed yet.:

• Garrett 2860-9 turbos with HKS actuators
• HPI dump pipes
• ARP head studs
• Tomei 1.2 mm head gasket and compete Tomei gasket set
• Nismo fuel pump

So my current status is a well running and reliable car which is plenty of fun on the street.  However, I plan to track it in the near future, and am wondering what the next set of mods should be knowing that.  I have a new set of wheels and tires, and I've got dedicated track pads and Motul 600, so basic track stuff I've got covered.  

I'm just wondering if there are any recommended mods I should move to the top of the list for a track car.  I would prefer to not have to pull the motor quite yet, so replacing the oil pump or putting a baffle or extension on the sump is not really an option at this time.  The list of stuff I have above for the turbos, head, etc I have been holding off on installing because I wanted to wait until I could afford a Haltech ECU, boost solenoid, wideband sensor, etc (and possibly cam gears / cams) and then do all of that at once and tune it.  So would you say that overfilling 0.5-1 L of oil is enough for the track?  Or am i missing obvious MUST DO mods before track?  Oil cooler mandatory?  Triple flow cam baffles?  Head mods?  Injectors?  Fuel pump?  Or am I good to go as is, just keeping a close eye on my numbers and not killing it during the track day?

Sorry for the long post and thanks for any guidance.

I guess no advice...

[Sinista32]

Put the extra 0.5 litre of oil in. Keep an eye on the oil pressure.

Be prepared for the oil starvation and spun bearing.

HKS Hi-Silent isn't that "silent" lel
I drop 5L of oil every service, works fine for me *shrugs*

Ha, well that's what I'm trying to avoid. If I overfill and watch the pressure, should I be fine for track? Or do you think theres another mod that's mandatory pre-track?

Hi Silent isn't quiet lol.

Ha you've now told me three times .  To tell you the truth though, it's actually pretty damn silent. Currently have the stock turbos and dumps, with a Mine's downpipe, decat pipe, and the HKS Silent. 

[Sinista32]

The only mod to avoid this is replacing the crank collar that mates to the oil pump and securing the oil pump.

After some other good advice hey.

Always keep your fuel tank over a quarter to a half full on the track to prevent fuel surge (fuel cut) due to air in the fuel lines caused by the fuel slopping around in the tank under hard acceleration / cornering. Keeping it over quarter to half should prevent this.

Didn't really think of the fuel level, so thanks for the heads up! 

I'm planning on doing oil pump, crank collar, oil pain, head mods, etc all in the next 18 months when money gets a little less tight.  But currently the car is in great shape and I'm gettin' the itch to take it to the track.  Just want to make sure I don't do anything stupid.  But I'll do the above recs and only drive the car at like 7/10s on the track.  Won't try to break any records.

Oh did I? I'm an old person now, which also explains why I say it's not silent lol.

Oh yes, +1 on the keeping fuel above 1/4 on the tank, I experienced 'surge' on a track day because of it.
