Hi can some one help. I have a 1990 r32 gtr i have rebuilt engine with argo forgies argo billet rods and acl race bearings. Engine has been goin sweet untill last nite. standard but but had it checked before re assembly

Oil gauge has never read right been told is a common problem

Question do 32 gtr have an oil pressure light if yes mine must not be working?

Boosted to 16psi racing some1 end of race car making big knocking noise have had in diagnosed and yes it has done a big end.

Have not tested oil pressure on mechanical gauge.

So what would be th most likely cause of oil pressure loss in these cars.

What is the soloution to this problem?

What is easiest method of removing the sump. A dropping cross memeber or engine removal.

one more question if they do have oil pressure light does it come on when ignition is frist turned on.

the oil light should come on when you turn the ignition on before starting.

and the gtrs are common to have oil pressure problems. i blew my oil pump ( common to go ) and i had to remove the sump to do so.

and to remove the sump you have to take out the gearbox as bolts are inside which are hard to get. i took out motor and box.

and 16 psi is alot i heard to be running on standard turbos.

This is all true mate . Often the oil pressure sender will fail and read low pressure (very common as said and oil light is on guage unless bulb is shot) You still getting pressure afterward? I hate hearing this with fellow rb owners but its nearly a fact of life... if you rebuild it... replace the oil pump. and /or crank collar with early r32 engines. Oil light should come up during ignition start up. Easiest way to remove oil pump is remove engine...remove sump. You've probly heard it before but oil pressure is utmost important and i wouldn't touch a car fo any sort of maintenance if it was reading an abnormal oil pressure. I wouldn't even drive a car if i thought something was suss! All in all from what you've indicated as the cause a spun bearing requires a bottom end rebuild anyway. sorry to hear.

bad luck mate, that sux :( hope u can get it fixed without too many hassles..

can I just ask, as Im looking at possibilities of forging my own engine... what makes a recently rebuilt motor with stronger internals sh*t itself and not even reach 10,000kms? I thought they would last after being forgedt?

gl with it mate.

There's probably a lot of things that will make it go before you hit 10000k's.

Including, but not limited to:

Oil problems

bad assembly

shit getting into the engine while your rebuilding it (aka, metal flakes etc)

      Duncan's V37.......race car?

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
