Hi Guys, i have a freshly built rb25/30det s2 head runs mint makes a nice 410kw on e50 but my oil pressure seems very high, it has a brandnew NITTO oil pump with gtr pickup...

Oil pressure on start up is 100psi, even when both oil and coolant temp are at running temp and after a 2km drive up my hill/mountain which i live at the bottom of and about another 1km along the flat it stays at around 100psi untill probably about that 3km of gentle driving it drops down to a cruising pressure of about 60psi and plays ball and flucuates from approx. 25psi-80psi depending on revs like you'd expect.

Ive got oil cooler with filter relocation and two seperate oil pressure sensor, one going to a gauge and the other is a brandnew bosch combined oil temp/pressure sensor going to my link ecu which shows on my powertune dash and both gauge and dash are showing the same oil pressure readings.

To me the 100psi seems high? Also to add im using 15w-60 HPR15 Penrite full synthetic oil..

 

Cheers!!

Ok awesome thanks everyone! Good to have some reassurance!! No oil thermo...

Get a thermostat, helps with getting the oil at operating temp/viscosity quicker. Also reducing the likelihood of over chilling the oil when you're out and about town on a cold day.

      Thanks for all the replies! I also wanted to ask if wheels that were fitted on Ford Falcons would fit the 350GTs as well? In the area I'm at there aren't that many options for secondhand wheels and new ones here are way out of my budget. From what I've seen, most of the wheels that are available that were fitted on Ford Falcons have an offset of +33 to +36, with a centre bore of 70.5mm whereas the stock 350GT's ones are 66mm, can't seem to find any hubcentric rings that fit that difference though.

      215/45/18 tyres are probably a little on the low side compared to the factory tyre, it should be closer to a 245/45/19, which will get you about an extra 11mm of height, and should make you speedo read a bit closer to reality. 245/45/19s will be a bit too far the other way and you risk a speeding ticket as your speedo might read slower than your actual speed.  245/40/19s would be correct if you are going to 19in rims, they will give you a similar total diameter to the 245/45/18 tyres.

      That's something I forgot to put in my list. The aggressive anti-squat in R32 is a f**king menace. I still need to decide if I'm going to drag the subframe out of my car and weld in the GKTech corrector kit. The main reason to dither is the need to switch to spherical joints in the lower arm to account for the twist induced in the rear pivot caused by lowering the front pivot. And yes...we do put better subframes in R32s, and I wish I'd gotten an S14 one instead of an A31 when I did the "take off and nuke it from orbit" HICAS delete all those years ago.

      V37 Alarm settings and what the buttons do.

      By HYBRID VL · Posted

      I have been looking at some setting on the alarms for the Q60 and what buttons do and so and also been looking for details on the alarm in my V37 which is a standard issue with the car. settings like window roll up and a few others seem to not work at all. i cant seem to find exact info on V37 alarms so Q60 is all i can really go off i have not tried 400Z alarm settings or info yet so that will be next. any one got like a sheet of info on the alarm system in the V37 as all my documents are in japanese but i thought the system would basically be like standard through similar models?
