Hey guys, My engine started playing up at the end of last year after some tune and spark issues. Compression was showing that each cylinder was still making reasonably healthy compression, but there

Any reason why you went Garage101?

No major reason, someone recommended them & they can tune Haltech's....so i thought i'd give them a go.

The car's still there atm due to some part issues (it appears i've ordered or received some incorrect fuel related parts/fittings)..I'm away for work and there sorting it out for me, so i'll post up how it all pans out once it's all fixed next week.

Righto - little update,

Picked the car up from garage101 a few days ago. Danny only put a run-in tune on it with no timing advance and 4400rpm cut off. I'm still waiting on some parts (still runing stock cat and front pipe), hence i didn't go the hole nine yards with the tune.

Anyway, just took the car for a spin then and the results are looking promising. Got 0.8bar of boost @4000 rpm and i'm not feeling a hole lot of difference in response from the stock turbo's. The updated clutch/gearbox took abit to get use to, it's a more on/off when cold then before and shutters a bit at low rpm. However, once it warms up...whle different story, so easy to drive with and gear changes are so smooth.

I don't expect to get time to finish the car off until sometime in the new year, but i can't wait.

Oh, one more thing - apprently my diff's might not be standard...when we push the car a few meters in neutral, the both diff's lock up and it becomes impossible to push the car any further...i know nothing about diff's, so doe's anyone know if that is normal?

can i ask a question mate,

y Stock RODS on a build like this , wen u did everything else in the block ,

Good question mate - Paul advised that he had personal tested stock rods well past 800hp - i doubt this engine will ever see past 600hp, which means they were well and truly up to my requirements and the money saved could be applied elsewhere.

In retrospec, i sort of wished i'd put a stroker in, but the line has to be drawn somewhere i guess.

Build is sounding good mate! Glad you got the car there safely.....

Look up NITTO GTR, they are running big power on a stock bottom end and loving it!

lol, you should have seen my WTF face when i picked it up and tried to turn the steering wheel for the first time.

yep definitely aware of the nitto gtr, I'm a big fan of it.

But it's important to keep in mind that although it's got the stock bottom end and still runing strong, only a pull down is going to tell if the components are still in tip-top shape. Paul's been through this process already, so he was very confident on the reliability of the parts that went into this motor.

That yellow thing is MEANT to break but it has stayed together....... Good to see it stay together though!

Was the belt just not on since the build?

That car has been through few different motors

And is waiting to blow the stock one so the stroker can go it, had a good chat at the nationals, nice bloke that i spoke too!

Anyway, point was with 850rwhp the rods are still in one piece so with WA's lack of E85 i cant see massive power levels being a problem for this epic build.

Now i shall GTFO :)

well...sort of...it apprently came of in newcastle after less then 20kms of running (Paul was driving - i had already left for Perth). At first i thought it was ROSS blancer syndrome multiplied by the fact we noticed the adjuster bracket was bent when we were bolting everything back up. However, the real reason wasn't apparent to i went to install a new belt in Perth....i forgot to tighten the power steering bracket bolts...the thing was just sitting there loose. I'm lucky the hole assembly didn't come off and cause some major damage.

I've now gone through and checked every bolt in the bay i can reach, but I haven't come across any other potential drama's.

awesome build there mate :woot:

Thanks mate. :cheers:

I've had the car in storage since mid December, so there hasn't really been any progress lately :down: . I'm currently waiting on a custom venom cat and a few random bit's from nissan Japan and then it's pretty much off to the tuners to pump some boost into her.

Hopefully i'll have a big update towards the end of Feburary with some results and some info on the next phase of my build.

hey wedge, whens your car getting dyno'd? my bro had alot of help from paul also, would like to see what it pulls ;)

gotta love pauls work

Yeah Paul's a bit of an artist when it comes to RB's. He did menion he had done some work on a car in WA - fairly custom head if i remember correctly?

Work's been taking up all my time at the moment. - I'm going to have some spare time next week though, so hopefully i can get it on the dyno....it's really starting to drag out lol.

      Put a fuel pressure gauge on it. Replace the turbos. Probably completely separate issues.

      Recomended Coolant For Gt T R34

      By silviaz · Posted

      What copper washer do you guys use on the bleeder bolts? The existing one I have I had no idea where to find it in a local store, I did buy some online but that are only 1mm thick whereas my old one is 2mm+ thick and when I put the new washer out and squeeze the top radiator hose I can hear a bit of air but not with the old one. Does this matter? The new one doesn't leak, but the inner diameter is a bit loose whereas the old one threads on the bolt.

      Howdy all, after being out a few weeks ago on a spirited drive in my GTR I have 2 issues that oddly have appeared at the same time. Whilst accelerating quickly through the gears all of a sudden i’ve lost power at the top of third gear (below redline around 6000rpm) for no obvious reason.    From that point onwards the car has been running rich on idle, won’t really rev under load without a ton of black smoke and the odd backfire, and dying as a pull up to a set of lights unless I keep the revs up around 1500rpm. In addition when shutting down the car that same night (I was 10 minutes from home) I noticed one of the turbos was significantly noisy on wind down when shutting off the engine. After letting the car cool down overnight it starts up fine, although once it gets to temp the revs start to creep up and down, the exhaust is darker than it should be and it also sounds like it’s running rich (fat note) I’ve put a new set of plugs in it - no change, the old plugs all seemed OK with two of them being somewhat richer/fueled up than the other 3 with 1 being borderline. I’ve smoked tested the intake system via the front of the Turbos, found a split vacuum hose going to the factory boost gauge sender, which I have since replaced.  Also found another leak on the gasket coming off the rear turbo outlet, have also replaced this. After fixing both of these leaks - still have the running rich issue. I’ve also tried another pair of AFM’s - no change here After pulling off the front turbo intake pipes, there is obvious shaft play in the front turbo, which now hisses loudly on light revvs although I can’t see why this would make the car run funny even under idle. I’m curious to know why it’s running rich before I potentially replace/rebuild turbos. The car is completely stock <50,000kms  other than an exhaust. Oil and coolant are all clear. I haven’t bothered with coil packs as it looks like they won’t be the issue due to condition of the plugs. Any help appreciated as I cry myself to sleep!

      R34 4 door side skirt identification

      By Rezz · Posted

      No probs at all. I used to love trying to dig up obscure info for those in need where possible going back 20+ years on SAU.  I did have another look and couldn't come up with any closer match. I'm leaning towards those skirts in your first pic are custom fitments, cut down/extended or from another car entirely and modded to fit an R34 sedan. I would've thought someone in Japan had them and taken a photo at some stage over the last 2 decades but there's nothing. Someone out there must know surely.
