I've just removed an engine from a 1993 32 GTR to find it had a pull type gearbox. It is not a vspec but is a late 93. The oil pump has been replaced along with the water pump. Is there any other tell tail signs to if it's running a full face drive crank from looking from the outside? I don't want to pull the motor down if I don't have to as it is going to be put up for sale. Just seems a waste as the only reason we removed it was to fit a 33 motor.

Matt

Thanks in advance

u "shud" be able to tell by lookin directly at the front of the oil pump. if u can see a gap around the crank to oil pump its early.

So I pull the harmonic and timing cog off.. Can you elaborate on this gap? The motor has a N1 oil pump on it now.

Actually I think I know what you mean. There will be a gap on a half face crank as the flat bit of the drive doesn't extend right out to the edge of the pump. Should be pretty easy to tell.

I will have a look and put some pics up.

Cheers

Matt

im pretty sure i could tell mine. http://www.skylinesaustralia.com/forums/topic/154710-rb26-32-or-33-crank/page__hl__collar

the d shaped drive on this crank would be half as long on an early 1. also u will see it being round inside the pump instead of following the correct profile.

i've heard (but can't prove) all R32's had the same crank collar, could be wrong as both opinions are floating about. If you still have the old oil pump you should be able to see the wear marks from the crank collar on the inside drive surface. If the crank's a short nose you'll see the mark goes in about 5-7mm , a long nose would produce a (substantially) longer mark. Would save popping the seal.

      Who has a Infiniti Q60, Q50 (V37)?

      The ATTESSA is functionally identical to R34; there were a bunch of JDM models that continued ATTESSA including Fuga/Q70, Skyline/Q50, Cima etc as an option. All with Auto only and I think mostly for snow regions. AFAIK there were no AWD VR30DDTT sold in Australia - it is on my to do list to check regs for racing a LHD car in Targa/ATR/AASA/CAMS events because if I can get the auto to work it would be interesting to run a 4wd car The Ecuteck TCM tuning is the same model as their ECU tuning, they already have it for R35 and Dose's favourite, BMW. You buy "points" to allow your computer to be tuned, buy either a bluetooth (phone app) or bluetooth+USB+Key (phone and PC) dongle, and pay for a tune that will be locked to your tuner ( ). You can also access the tuning software yourself but 1. it is mega expensive and 2. these computers have a billion parameters that intersect, so how could you ever spend enough time on it to get a decent result.

      Or, is it a case of what it is like owning an R series Skyline? NFI what the previous owner has done or fiddled with... Ha ha ha After reading through this thread, I went on a bit of a research about the Q50/Q60. Now I'm quite intrigued by them! Is the AWD in them more like a WRX where it's always AWD, or is it more like the ATTESSA in the GTRs? By the sound of this TCU tuning, this sounds like a case of someone has made some real software for it, and you just need the right piece of hardware, and then you license that specific vehicle/TCU. Or is this a case of the software will be really expensive so only a few tuners have it, and you still have to pay a license per vehicle?

      R34 25GT Engine Light 21

      By popular demand.. it was a coil. Got my hands on 1 new OEM coil, replaced with the one that made the less noise difference when I unplugged it while the car was running and started the car up. No stutter and the engine light was gone. I guess I’ll buy the other 5 they have lol

      No, code 21 is very straightforward. It can only be the things described in that diagnostic flow. In fact it has no way of knowing that the spark plug resistance is out of spec.

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.
