oil pump failure like that can be from a combination of two things, tight clearances, perfhaps too tight + oil too thick

what oil were you using?

haha bubbas answer to all problems in life is a rb30det conversion :P

Edited by snozzle

Sounds like a pretty good answer to a problem haha. Scored a 30 bottom end today for 50 beans looks to be in good condition tho, might be the way to go and tuck the 25 under the bench somewhere.

Is anyone around here using the Nitto oil pump and other nitto gear?

nah not yet but im planning to buy a nitto oil pump.

Was using motul 8100 5w40, measured my crank collars thickness on the flats to be 41.1mm .. and from the jigsaw puzzle of a oil pump, the gap is about 42mm on the flats

where did you score the block from?? my blocks only good for 40 thou now since is has some scratches in the bores.. chasing a new crank/block if anyone knows anyone that has one..

anyway u look at it comes down to how much $$ u got, rb30s arent as cheap as ppl lay out (ask my wallet)

it depends if u wanna do it right or if u wanna do it dodgy n replace ur 30e bottom end 1ce a year.

if u do go down that path come buy an rb25 head off me i have 2 spares

The fact that it's an RB30 doesn't really have anything to do with cost unless it's going in a 4WD.

Rebuilding costs are rebuilding costs, if you're building an engine for a RWD application then the difference between building a 25 you have or turning it in to a 30 is $50-100 for the RB30E.

If you're putting it in a 4WD (GTS4/GTR) then you're up for the cost of the sump adapter.

It's the actually rebuilding in general that people don't realise costs time and money :)

agree and disagree

good find with the 30 bottom end!

i love how ppl say "u can find rb30's for $50!" took me 3 months to find one n cost alot more than $50.-wreckers even wanted $750 for a 30e in a written off VL!

if ur going to build/forge go 30det over 2.7ltr but yeah there are things to consider: compression, height, modifying the head, vct etc, head gasket, engine not licensed etc etc etc did my head in for about 6months, glad its almost over! :)

The wreckers down here wanted a lot for a bare block, but there are that many dardy people down here it wouldnt take much to find one. Why wouldnt you be able to licence the 30 engine?

The RTA do that 15% engine increase dont they?

30s can be found cheap, just gonna hunt around. i ended up buying a complete s3 31 and selling a few bits off it, made money from it and got a good motor for free.

if you can do all the work yourself (apart from head welding and machining) and do your research it wont cost more than a few hundred for the actual motor

    • Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.
    • Hi everyone, I’m having an issue with my R32 GT-R. Sometimes, when the car goes over a bump or experiences some vibration, the 4WD warning light comes on the dashboard. When I check the code from the control unit in the trunk, it shows Code 19 – ETS Motor. However, everything seems to be working fine — if I turn off the engine and restart the car, the light goes away and everything functions normally. Has anyone experienced this before? Where should I start troubleshooting this issue? Thanks in advance!
    • I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
    • 310mm rotors will be avilable from Australia, Japan, and probably a few other places. Nothing for the front can be put on the back.
    • The filter only filters down to a specific size. Add to that, the filter is AFTER the pump. So it means everything starts breaking your pump even if its being filtered out.
