mickr33couple Posted October 23, 2012 Share Posted October 23, 2012 hi all im new to sau hopefully this is in the right section, ill get straight to the point, i bought a r33 which has been fully rebuilt 2000ks ago forged internals, plenum, high mount manifold, hybrid or garrett turbo cant remember what it is, apexi fc, hybrid fmic, coilovers, fuel reg, 044 pump, been told by the owner it had a GTR oil pump fitted when rebuilt, now i bought the car without hearing it as the owner pulled the head off, yes i know stupid thing to do but i got this r33 cheap... cheaper then buying a 6boost plenum and high mount manifold... now the old owner said reason why he pulled the head off is because he started to low oil pressure (cluster gauge) took it to the engine builder not sure if he checked it over but anyways told the owner the cluster gauges always stuff out common problem anyways, the old owner said that the car lost all power like it wasnt making boost... now nothing has been said about a drive collar been put on the crank for the GTR oil pump do you believe the pump has shit its self and thats why it had no oil pressure and now stuffed the motor? i have spoken to the engine builder and he hasnt said boo about a drive collar fitted... old owner story always changed he was also on rev limiter when it f**ked out... my guess is oil pump shit it self i will be pulling the motor apart to inspect just thought ill throw this up Link to comment https://www.sau.com.au/forums/topic/412185-forged-internals-rb25-drama/ Share on other sites More sharing options...
AngryRB Posted October 23, 2012 Share Posted October 23, 2012 oh well worst case senario is you replace motor and bolt everything back on, live and learn, bit dissapointing though Link to comment https://www.sau.com.au/forums/topic/412185-forged-internals-rb25-drama/#findComment-6592181 Share on other sites More sharing options...
Moodles2 Posted October 23, 2012 Share Posted October 23, 2012 Why a GTR pump fitted to a to a RB25 crankshaft, sounds pretty stupid. Link to comment https://www.sau.com.au/forums/topic/412185-forged-internals-rb25-drama/#findComment-6592340 Share on other sites More sharing options...
The Dan Posted October 23, 2012 Share Posted October 23, 2012 Why a GTR pump fitted to a to a RB25 crankshaft, sounds pretty stupid. They are the same factory pump anyway. I'm guessing he means N1 A quick search is all that's required to know to stay the hell away from those pieces of shit.

mickr33couple Posted October 23, 2012 Author Share Posted October 23, 2012 Thanks guys, so hopefully it has a "GTR" oil pump in it like the engine builder says it does therefore likely hood of it f**king out like the N1 is pretty slim, engine builder said the gtr pump cost $1000 so I'm not sure if it a n1 oil pump guess I gotta wait to pull it apart fingers crossed bottom end is fine Link to comment https://www.sau.com.au/forums/topic/412185-forged-internals-rb25-drama/#findComment-6592518 Share on other sites More sharing options...
mickr33couple Posted October 23, 2012 Author Share Posted October 23, 2012 Yeah I know about the n1 oil pumps stuffing out that's why I hope it's not a n1 lol it's hard to say what's wrong with the engine as I havnt heard it run but a strip down and inspect is gonna be a must Link to comment https://www.sau.com.au/forums/topic/412185-forged-internals-rb25-drama/#findComment-6592524 Share on other sites More sharing options...

mickr33couple Posted October 23, 2012 Author Share Posted October 23, 2012 What's funny? The price for the oil pump, or coz a gtr pump is just the same as a standard rb25 pump?

mickr33couple Posted October 23, 2012 Author Share Posted October 23, 2012 Anyways I do believe its a n1 oil pump as he said it was a upgrade from a standard pump and seeing as n1 pumps are high flow... So guess the crank doesn't have a collar and now has scored the bearings and crank Link to comment https://www.sau.com.au/forums/topic/412185-forged-internals-rb25-drama/#findComment-6592792 Share on other sites More sharing options...
mickr33couple Posted October 24, 2012 Author Share Posted October 24, 2012 (edited) Anyways here is a pic Can anyone tell me if that crank in the photo has a drive collar for the n1 pumps?

mickr33couple Posted October 24, 2012 Author Share Posted October 24, 2012 Thank you, so my tale on this engine is that, oil pump has fail due to engine builder not doing what is required with fitting a n1 pump which has now (guessing) f**ked the bottom end Link to comment https://www.sau.com.au/forums/topic/412185-forged-internals-rb25-drama/#findComment-6592936 Share on other sites More sharing options...
t_revz Posted October 24, 2012 Share Posted October 24, 2012 All pumps including stock really need collars not just the N1 Link to comment https://www.sau.com.au/forums/topic/412185-forged-internals-rb25-drama/#findComment-6592950 Share on other sites More sharing options...

If you pull it all apart you might find some simple issues and can salvage the remainder of the built motor. If you make an assumption that the problem is X Y or Z and try to fix that you could just be in for more headaches and lose the rest of the goodies the motor has to offer.
