hi guys


i am looking for a engine rebuild soon for my rb26 in my r34 gtr vspec


i want to know where did you go for your rebuild and what was your experiences, and how much did it cost ? in sydney ***


looking at a workshop that can do drive in and drive out service


might even do a rb26/30 conversion ?


its a street driven car, chasing 400kw+


atm im running a stock motor with tomei poncams, arp head studs and single gt3582r turbo



cheers guys


I have not had a build done as yet but there are plenty of shops in Sydney plenty capable of building strong RB's!

JEM in Ingleburn do good work and have some big powered RBs running around!

400kw+ isn't unheard of on the stock RB26 with E85. You're not exactly on the bleeding edge either; odds are it would last reliably for years at that power level. Especially with ARP studs you can wind some serious boost in.

I'm no chemist or engineer but from what I'm told E85 burns in a way that is less harsh on the internals. So if you're worried about having stock pistons and rods E85 might give you a bit of a safety net there! Also if for some reason something goes wrong and you are given a lean condition under load (eg your FPR hose pops off or wastegate line splits), your tune is much further from detonation than a tune on 98 would be.

just something to think about. Good luck with it

I used Alex at Birrong automotive. His prices are high but probably lower than CRD Gas motorsport etc. My results are untested, as my car is "panel beater stuck". Alex struck me as meticulous passionate, with good knowledge, like many "his way or the high way". He drags an RB R33. The posts above show sound reasoning, technology supports a Nissan built motor. Best Wishes.

Drive in drive out at a shop - prepare to get $$ raped.

If price is a question it's best to learn to do this yourself, rather than pay anyone. As already noted the factory makeup is already well equipped enough to hold what you want so a little over engineering on pistons, rods and studs should be more than adequate, and is something any reasonable mechanic can achieve with a little brain power.

You will spend 5 grand doing this yourself and knowing you did everything 100% or 15 grand at a shop which would more than likely have their local reconditioner assemble the motor for them. I have a few friends in the industry and this is the general norm, these big name shops seldom actually assemble the motors post machining. Those motors have a tendancy to come back with clearance/tolerance issues and/or issues with cleanliness leading to bad contamination damage. I am rebuilding 2 motors right now previously built by pros with these exact flaws (I am not a mechanic).

Do it once, do it right, do it yourself.

My 2c.

Well said. The fact is, if you want it done right do it yourself. There might even be a couple of guys on here that might want to help. Of course time is our enemy. Not all of us have it. The good builders charge high prices but there is still no guarantee they won't make a mistake. Having one shop build it, install it and tune it is the only way I'd pay a work shop. Get all your parts off E-Bay 1st and save a fortune. Don't expect too many people to name names as we don't want o cause legal issues. However, you may receive a few PM's.

Hi all,

Been down this path many times before. I have built over 10 motors in my lifetime, from when I was a struggling uni student to now (a struggling man with mortgages). Building to a budget and trying to save $$$ is hit and miss. There are way to many variables to go wrong. And instantly a blame game starts.

I am fortunate enough to now get work done at Powertune Aust. It is about this time last year I approached them having lost all faith and passion in owning a GTR and racing it.

All work done in house. All responsibility taken with a fall warranty on all work. Just remember the saying "poor man pays twice"

no doubt there are some very clued up peeps on this forums who are skilled enough to screw a engine together but that in my opinion is only a quarter of the exercise.

Happy to answer any questions over PM

:cheers:

Tool skill being a quarter of it, sure. The other 3 quarters lie in first hand experience, most of which can be read on forums like this and are authored by people like those in this thread.

Just need to be bothered enough to read, and read for long enough, so that you can save that 10k for something more important.

    • The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.
    • Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.
    • Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks  
    • Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..
    • I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.
