THanks 4 the info guys! much appreciated.

I'm not rebuilding it myself, Jap Car Repairs are doin it, in Clayton Sth for $2g.

He just said go "normally" i.e no redlining, no boost, no excessive acceleration.

ANyways Mineral oils it is. I think i'll go to the Grampians, nice up and down driving there, pretty far away too.

Thanks again.

Ali.

WTF - $2G is a very cheap quote. One of the cheapest quotes I have heard of.

Ali - Have you checked that Jap Car repairs have done alot of RB26 rebuilds?

I'm not slandering anyone, but even with stock parts it seems to good to be true. But if I'm wrong people - let me know

I just spent $6G on my RB25DET (oversize & ceramic coated Mahle Forged Pistons, shot peened/crack tested/linished GTR Rods, ARP VG30 bolts, ACL race bearings, O Ringed/honed/cleaned- Block, Crank checked & cleaned up, new valve springs, Greddy HD Timing Belt, headporting & polish & full balance & blueprint.

yeah it is cheap.....

The second best quote i got was for $2800, some1 in cambellfield.

I asked Nismo (they're actually called NISMA) in Sunshine, he wanted 4g.

I suppose reputation costs as well.

But its still better than buying an RB26 of a wrecker, and just swapping the engines over, as you don't know when it will go BANG, and the cheapest one i could find was for 4.5g with only 2 months warranty, where as with the rebuild im getting 12months.

The main mechanic there has rebuilt his own R32 and 200sx s14, plus heaps of others.

He's got the experience. I'm not sure whether he's built a RB26 though :S I assume he has.

What does the quote include?

i.e is it for disassembly and reassembly only? Parts and machining included? Engine in and out of car?

Quote includes all of the above.

Basically, I give him my GTR with the hammered engine, i get back a car with a working engine and 12 months warranty :(

He said that includes cost of parts, machining, labour (i.e assembly, removal etc.) and oils.

$ 2000 wouldnt pay for the parts and machining ! Good luck if you get it done for that .

:werd: I've just done it myself and paid around $2000 for parts and machining.

Which of course does not include 10hrs+ labour to take the engine in and out or the actual assembly.

Anyway......the thing I would stress is change the oil and filter early in the piece and also the coolant.....having seen what the engine shop considered "clean" I think its worth trying to fluch out anything thats left in the oil and water galleries.

That would depend on what you have replaced Duncan .

For instance if you use a new oil pump , water pump timing belt , tensioner and iddler pullies that would not be enough .

When i did mine about 18 months ago , i replaced all the above plus pistons , rings , bearings and rebuilt the turbos ( new cores ) at garrets ( $1350) .

Got the rebore , hone and crank reground and cil head done at mates rates ( all for $380 ).

It still cost me around the $4 K mark and my free labour of course .

If he gets it done for $2000 its dirt cheap .

yep absolutely....the only new parts I put in were oil and water pumps and rings. Reused timing belt, idler and tensioner, rods, pistons, crank. Had the bottom end checked, prepped and balanced. Had a head job. But that was about it. Brilliant price on the prepping...I want mates like your mates lol

But labour is what makes that price mad....Engine in and out alone should be 1500+

Next time you want to rebuild a donk let me know and i'll guide you to the right people .

Anyway his standard prices are not that bad , try $ 120 for bore and hone ( any 6 cil ) rb 26 cil head service for under $300 including seting the valve clearences ( rb 25 $220 ) and the crank bloke will grind your 6 cil crank for about $150 .

Most places would charge $6-7 k for a drive in drive out rb 26 rebuild with new pistons but using your old rods .

my previous ride was a mazda rotary (the MOST temprmantal engine ever)...

after i rebuilt it, i ran it in on a mineral based oil (like royal purple) for 500 km's not revving it part 3500rpm... after that put semi-synth and did another 500km's not letting it rev over 5500rpm... then at 1000 km's changed oil and sparks and got to flog the guts out of it revving it to 9000rpm... yay...

moral of the story is: running in is done so that you can slowly bed your pistons/rotors/hampsters in properly at their full potential... so slowly build up to flogging the guts out of your ride (not that u should give it a flogging 24/7, that can make things turn sour).

that is all.....

ps. please feel free to correct me if so needed. :)

      NPboosted manifold fitting purpose

      By GTSBoy · Posted

      No. The ECU's hose is for a connetcion between the plenum (assuming single throttle body, not ITBs) and the ECU's internal MAP sensor. This is the primary load measurement of the ECU - so you need to get this one right. This has NOTHING to do with the boost contol. The wastegate also needs to see a boost signal - but it is actually far better for it NOT TO COME FROM THE PLENUM (again, assuming single TB, and not ITBs). This should come from the turbo's compressor housing (assuming there is a nipple on there, which there might well not be), or on the boost pipe somewhere between the turbo and the TB. On the pipe from the turbo to the intercooler is usually most convenient. The boost controller is then located between that boost source and the wastegate, ACCORDING TO THE CORRECT PLUMBING DRAWING FOR THAT BOOST CONTROLLER. There is no general diagram or instruction that will be correct for every case. Then the other ports on the plenum are for purposes such as Duncan described. If the boost controller has an internal MAP sensor, for a boost display, etc, then it will want to be hooked up there, alongside the ECU and the FPR.

      Ok gotcha, so one post to fpr  another to bov  and I have the mishimoto boost controller and a link g4+ so I’d just have the tuner set it up properly. For the last two from plenum post throttle to  ecu/ boost controller, I know that I have a hose coming from the ecu that I was confused about so I assume that’s what connect to the boost controller from the ecu? And then the last is just from plenum to boost controller then to wastegate?

      Neil's R33 Gts-t Build

      From there, it was just a quick electrical check, prime the oil and start her up Which, is not what happened. 1. Bloody seppo Aeropro battery holder. Not only was it too tall for the battery (which I'll forgive them for, I have another battery the same nominal size that is taller than Neil's one, but the bracket is a fixed height so the battery was spaced up) But the thing that really shits me is the hardware to hold it on requires a 7/32 Hex key. WTF. No-one will ever be able to remove or install the damn thing without a hex key they don't own 2. Kill switch no longer worked once the console was installed. Neil mentioned above he had to adjust the length but it no longer cleared the console once installed. Sorted. 3. Suspiciously, the brake light holders were hanging in the boot with no globes. Sure enough the stopper on the brake pedal was missing so they are always on unless the kill switch is activated. Will pick one up tomorrow (turns out 32 and 33 don't use the same stopper) 4. All that sorted, I turned on the kill switch, turned the key to ACC. Nothing. Turned it to IGN. Nothing. Checked some fuses and found the main IGN in the boot was missing which improved things once it was replaced. Now ECU and dash lights turn on with IGN but still no fuel pump. 5. Turned it to Start....ECU on, no fuel pump, no starter. Plus the voltage dropped straight to 9v.  I suspect the starter is f**ked but am going to have to work through it all and see what is happening, really looks like more than one issue. Does anyone have the R33 fuse box key with the circuit it sources from (eg BAT, ACC, IGN, SRT etc) and supplies? I can find a translated list showing Amps and circuit without supply circuit, and I can find supply circuit without Amps and target circuit.

      3rd time lucky, the AAC is now all plumbed up after getting some final fittings All set up under the plenum of maximum access
