Weird Start Up

[2BNVS]

i got an r33 rb25/30 that has had a fair amount of work to it, new plenum, high mount, etc etc

it takes a couple goes to start, and it sounds like when it tries to its gonna stall, and when it does sorta start theres a huge pop, ( but not misfire, like an actual pop) and my oil pressure gauge reads 0 from the start (but i heard the senders are faulty on rb motors and to fit a new gauge) then after about 5 mins warming up everything is normal

if anyone can give me an idea before i take it down to my mechanics then that would be great,

more info on the motor is available if someone can help, just cant be stuffed typin it all out now 1st

cheers...ben.

what oil is in this thing dude. is the car stalling or is the management seeing no oil pressure and shutting it down?

its got hi performance oil ( forgot the brand) which my tuner runs in all his performance cars ( in saing that it was fine when i got it back from him) just lately its been playin up ( only done like 20kms since) when i go to start it i have to rev it otherwise yeh it will stall, and oil pressure is fine when i shut it down just the 1st 5 mins its not reading it, then goes to normal range

Of course, start with a cold start mechanical guage reading. The results of that will determine whether you keep looking for problems or not.

Wonder if that pop is a blow back through the intake, not good if it is.
