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.

      Magnetic Drain Plug Snapped in Half

      By kevboost7 · Posted

      Update: I got the magnet out. I bought 3 different flexible magnetic reach tools, but none of them worked. The magnet on the tip was all less than 2lbs of force, so i had to buy a special cylindrical magnet that had a pull force of 9lbs.  The magnet finally came in the mail yesterday, so i got under the car to get to work. The super strong magnet isn't that long, so i only have about 1 finger pinch lengths to hold it. I was so scared when i was going in the hole, that the 9lb magnet would just fly away inside the oil pan never to be seen again, but i had my butt cheeks clenched and finger gripped on that thing so tight, i managed to get it to suck the other magnet out.  It was a victory for me last night.

      New fix for low tyre pressure from bmw

      By MBS206 · Posted

      Yep, pretty much what you said is a good summary. The aftermarket thing just attached to the rim, then has two lines out to valve stems, one to inner wheel, one to outer wheel. Some of the systems even start to air up as you head towards highway speed. IE, you're in the logging tracks, then as speeds increase it knows you're on tarmac and airs up so the driver doesn't even have to remember. I bet the ones that need driver intervention to air up end up seeing a lot more tyre wear from "forest pressures" in use on the highway!

      Anyone know this frontpipe?

      By sunsetR33 · Posted

      Yes, but you need to do these type certifications for tuning parts. That is the absurd part here. Meaning tuning parts are very costly (generally speaking) as well as the technical test documentation for say a turbo swap with more power. It just makes modifying everything crazy expensive and complicated. That bracket has been lost in translation many years ago I assume, it was not there.

      Hahaha, yeah.... not what you'd call a tamper-proof design.... but yes, with the truck setup, the lines are always connected, but typically they sit just inside the plane of the rear metal mudguards, so if you clear the guards you clear the lines as well. Not rogue 4WD tracks with tree branches and bushes everywhere, ready to hook-up an air hose. You can do it externally like a mod, but dedicated setups air-pressurize the undriven hubs, and on driven axles you can do the same thing, or pressurize the axles (lots of designs out there for this idea)... https://www.trtaustralia.com.au/traction-air-cti-system/  for example.... ..the trouble I've got here... wrt the bimmer ad... is the last bit...they don't want to show it spinning, do they.... give all the illusion that things are moving...but no...and what the hell tyre profile is that?...25??? ...far kernel, rims would be dead inside 10klms on most roads around here.... 😃

      You're just describing how type certification works. Personally I would be shocked to discover that catalytic converter is not in the stock mounting position. Is there a bracket on the transfer case holding the catalytic converter and front pipe together? If so, it should be in stock position.
