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

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

      R34 Gt Auto Tuning

      If you want to do the wiring, the GTT engine ecu has the same pinouts extra that the seperate TCM in the NA car has. You can literally grab the wires/pins that lead into the Seperate TCM and wire them into the corresponding pins in the GTT Engine ECU. You could then in theory Nistune it. I realised this when everyone put it in the too hard basket and I actually looked at the f**kin R34 manual. This is after I had previously had a seperate aftermarket TCM controller in my original N/A chassis car and a very built gearbox from a GTT, running a seperate Haltech engine ECU. I ran into this issue when I re-shelled the car into a GTT shell, so my aftermarket TCM was no longer plug and play, because the loom/modules were not present. I was pretty livid when realizing just how simple the original fix actually was. It sat for 3+ years at various workshops trying to find a solution. In practice none of this is a worthwhile idea for a lot of reasons, generally surrounding the shitness of the NA auto, the autos in general that come with skylines, and the NA engine and lack of gains. The gearbox is specced for the 2.5L N/A and barely at that level. If you have to pay anyone any money to do any of this, that is money spent on manualizing the car and it's not even close in terms of a comparison. Learning to drive manual is simpler than going through the pain of dealing with the N/A gearbox and he'll have fun to boot.

      Semi-correction to my blanket statement that you can't bend rubber hoses. It seems that you can get most of a result, by doing as this guy does. I wouldn't promise that the bends will stay in the hose forever. I think if I found they wouldn't stay, I'd get a larger hose and cut some 90掳s out to go over the bends I wanted to be in the smaller hose, as a reinforcement.

      Just a heads up. Mine has just failed. When i turn the car on it just reboots everytime then the word "Android" shows up then goes to a black screen. I've aksed the company i got it from for some help but it's passed their 90 day return so they wont help. I have to swap back to my old system this weekend 馃槶

      Does the car have to stay auto? If so, you might be looking at a ZF swap in future.
