wouldnt you be running a 26 loom with your 26 head?

What episode of house are you referring to...i just watched the latest season 3 ep i got from the net...it was pretty good.

Edited by r33_racer

Geoff,

VL injector plugs are the same as RB26 inj. plugs.

Depending on the 'quality' you can get cheap good aftermarkets that are sold in a pair for $16. So Total $48. If you go the really nice ones. :D they are near double.

Motortraders/Coventry's stock them.

House just started again, so S3E1. I'd download it but I'm too busy with BSG, SG1, SGA and such for the wife. Might even get to dl some car stuff for me if I can rob some bandwidth..... >_<

Running 25 loom with single Z32 AFM as at this stage I won't be running enough power to make that an issue. Later I'll change to Q45 as necessary. Nice sexy stainless pipe for the single afm/twin turbo setup.

Thanks for the info Cubes. I'm sure I had already seen that but with so much on I'm feeling a bit overwhelmed.

That's right mate, no need for temp sensor, run all the 25 stuff including the TPS with a mod and see how I go with the IAC. Also from the RB25DETT I have setup a single O2 Sensor on the Y pipe. Tomei have an adaptor kit for the 26 intake to RB25 head and use all the stock kit with adaptors.

geoff one thing regarding the injectors & plugs, my SARD 800cc ones came with their own plug that i had to wire into the loom (even the sard plugs had to be shaved for them to fit) im not sure if this would apply to u, but just a heads up :)

The tuners still have our car...been there all week. Car wont make more power then about 290rwkws and it keeps overboosting once it reaches its target boost. They have been playing with timing, and wastegate springs....they think the problem is a faulty gate, which is sticking or something...so another is coming from turbosmart which will hopefully clear it up.

Initial thought after playing with wg springs was that the timing was out a few degrees, as in piston was not tdc when we set it up...But now the blame has been shifted back to the wastegate. Hopefully it gets sorted cause races are next weekend. Car still needs a wheel alignment.

ummm I had similar probs on Wed. Got a 60mm HKS gate and before the dyno I replaced the 18 psi spring with a 8 psi spring. Now it is too soft and opening to soon even with the avcr. So goes back next Friday after I put the old spring back in on the weekend.

r33 racer - what boost are you running to achieve the 290rwkw ?

Target boost was 1 bar. After that is goes stupid...however im not sure if it was 1 bar that was making the 290. Im guessing it is, because when it overboosts they havent been taking it any further cause it is leaning out fairly aggresively.

Does that work out roughly??

let me know when you find out.

I have been having drama getting mine to make any real power which I cant understand too be honest.

ATM it is making 280 rwhp ( pffff ) on 10 psi - thats on Matt Sprys dyno ( PITS ) which is renowned for being unrated, but even so Im still a little mystified.

Maybe when we crank more boost in it will all come good.

My engine is this:

"SPOOL" R33 FOUR DOOR RB30DET

RB30 Block - bored 40thou, decked and oring'd, ACL Forged pistons

ARP Head studs and mains studs

Nitrided crank

SPOOL H Beam conrods

ACL race series bearings

Jun oil pump - crank snout modified to suit

R34 NEO head - HKS 272 / 9.35 cams, Performance Valve Springs, ported and polished by JHH performance

Garrett T04Z turbo 0.96 ex housing

Sard 850cc injectors

6 Boost manifold - HKS 60mm wastegate

CPC plenum - VH45 90mm throttle body

ATI Harmonic Balancer

OS Giken Twin Plate Clutch

whats the compression ratio for the engine?

otherwise the specs would suggest your going to make some pretty serious power, definitley much more than what your at now. Id be gutted if it made less than 350rwkws on 1 bar

I wouldn't be concerned. Get some decent boost in to it.

A mate with a GT35r .82 on his RB30DET made 183rwkw on 8psi.

Pushed 15psi and it made ~260rwkw and 17psi 270rwkw but thats where it ends due to a 2.75" exhaust that narrows to a 2.5" muffler. :S

comp ratio is 8.5:1

had several bolt on probs previously to this run, which I ve recently sorted, bent plenum, fuel pump issues.

But fixed all those, new 044 pump etc. No leaks, A/F ratios all good now.

I agree cubes, I told Matt that this Friday to boost it until it pings :-) , as the engine will handle near enough what ever we put into it.

Ill be running 100 octane and I wont be happy if it doesnt make some serious power.

And if it doesnt Im not sure where to look as Ive pretty much sorted every other issue that has come along.

Feel free to suggest anything - because at 10 psi I really thought it would be making more power, I guess if I pump 25 psi in on a proper tune it might make what Im looking for....but who knows until Ive done it

what are those pistons then

ACL NZ said they didnt make any pistons that would produce that comp ratio and ACL Aussie said they didnt either

I am running the RB25 R34 NEO head - it has smaller combustion chambers than the R33 head. So they are just ACL Forged pistons for the RB30ET.

dont get me wrong guys - but I keep hearing these big figures from similar engines, some less and I start to wonder if all these dynos are over rated ( or maybe the one I use is way under rated as stated above ). I wouldnt really say this but I have a mate who has a very similar engine to mine but with bigger cams, RB26 head, twin medium size turbos and at 20 psi he is making 420 rwhp on the smae dyno as the one I am using.

yeh i know what your saying mate....im starting to feel a little stupified...cant work out where at minimum 80rwkws has gone missing, and why now it wont hold boost. What the frick is going on....Ours should be holding boost and making more power and so should yours....some gipsy has cursed us and our rb30dets....:P

    • My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though. 
    • Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno
    • Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
    • BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
    • My experience with Rising Sun Exports Before agreeing to the sale I tried to do as much research as I could (obviously), his Facebook reviews are 98% and he goes Live at least once or twice a week. I contacted 2 people in the UK who had used him for their imports, both had positive feedback. His explanation and talk through of the import process was thorough, answering any query no matter how stupid it was. It felt as soon as the money was sent, communication dropped off. I asked for shipping updates every 2 weeks or so, not wanting to pester him, he never had any updates. I wasn't informed the car had been dropped off at the port, I only found out by his Facebook story. I asked for the photos taken at the port, knowing he would need some for insurance purposes. I received a few 5 second clips and that's it. When asked again, he said his staff had them. Weeks later I asked again, he tells me he doesn't have any, but does have 50 photos from the original advert. I never received them. I eventually got the documents sent via WhatsApp after I mentioned the port was requesting them. I purchased a CarVX report, to find out the vehicle is a Grade R with recorded accident damage, first recorded in 2017 when it was first auctioned. He never told me the grade, then again I didn't ask. His response was "Grade R means nothing, it wasn't chassis damage". Still, I would have liked to have been informed about it. Jon prides himself on being open and honest when it comes to inspecting cars, it's his main job doing so at the auctions for customers. When the vehicle arrived in the UK I noticed a few little cosmetic issues. It's a 21 year old car so it wasn't going to be mint condition. The side skirts are cracked on each corner and the sealant is failing. The front grill on the bonnet/hood isn't secured very well, mounting studs are missing. Both minor things, but again, it would have been nice to be told. During a Facebook Live walk around video of the vehicle, he mentioned it has a front Whiteline anti roll bar/sway bar. While on the inspection ramp, I noticed the stock item has been installed. When first questioned, his response was "the ARB? Switched? Since when, it never had them". Since sending video and photo evidence I've not received a response. I'm probably being over critical of the overall condition of an old car, but all I wanted was honesty (which he claims to have). I'm aware I wasn't his only customer, he's busy doing XYZ but other reviews praise him for great communication with regular updates and photos, I felt I didn't receive the same treatment.
