I will post here cos u can't attach pics to a PM.

You can have it for $40 if you want it - I think it cost me about $60 to get made up.

Pics attached - the flange bolt holes are at a 45 degree angle to each other .... not sure if this is normal, but you would want to check. I hope the pics show what I mean.

I am in Northgate fyi

Sorry, it looks like the sale is goin to Nightcrawler. But, yeah the flanges are meant to be set at 45degrees of each other on the cat. It should be a direct fit to your standard or aftermarket exhaust, provided its not a custom one. In the unlikely event it doesn't fit it only cost around $15 for Profix to knock out & re-weld flanges to align with exhaust.

well, had the new pipe fitted, and exhaust put on. All sounded sweet.

Then had the car put on the dyno where shaun started to give the car a tune to see what she could get.....

Made absolutley SFA difference....the car makes about 133 odd rwkw last time i had it tuned before it started to struggle to make power.Now the top end is better, and it makes a little more power but she struggles like hell.

It topped out at roughly 145odd rkwk then didnt make any more. :) Needs to go back to Shauns in a week or two for some problem solving. Might be cam timing is off, or something stupid like a boost leak.....who knows :(

Im soooo pissed....but the car does sound very nice with its "free flowing cat" now :cheers:

is this power figures for your RB31DET? i'm presuming your engine is fully standard aswell as your turbo? how different is yours to joel's?

Yes its my rb31det.

My engine is built to the exact same specs as Joels. (they were built side by side :) )

Turbo is a rb20det highflow jobbie (not done by me, but previous owner of the car).

My engine only has a few bits like rb20det oil pump (joel used rb25det) bigger fuel system (550cc, 044) and q45 afm/pod. Other than that they are identical.

I had some STR cam gears fitted when i had the motor installed, and Shaun reckons they may be a tooth out. :( I dunno myself, but it has to go back to get it all sorted in a week or two.

Dont worry about it Maxx, we were justy finishing as Joel went to leave....it wasnt gunna make any more power yesterday unfortunatly :(

      Unpeeling the Orange

      I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!

      Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.

      The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!

      The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
