I don't know how many of you care, but I thought I would let those interested know what's going on.

Car is still off the road. Nothing new there. Sticking with the rb25, no rb30 bottom end for me, at the end of the day it seemed all too hard for the mechanics up here. I am getting the engine rebuild up here in Darwin through a mates good friend. He isn't charging labour so WIN! Motor was stripped down and 4 pistons had melted, the other 2 were damn close in getting there. Ordered parts: Arias 20thou forged pistons, 0.074" metal head gasket, full gasket and bearing kit as well as adjustable cam gears for a little over $2k. Managed to get that price through another mate who works at Indy's and is only charging them at cost. When they arrive (begining of next week) block goes in for machining and everything gets installed.

Car should be back on the road by the end of this month / first week of October. Dale (mate from PF) if flying up to tune her for me. I had a few people interested in getting their cars tuned by Dale as well so he will do their cars and then we will all go to the pub and get pissed.

Dale will fly home and my "f*ken whooooosh" will be back shooting flames through the dual cannons. LOL Or not...

Anyway, so there you go.

Rods and camshafts will be ordered at a later date. More than likely after I move into my new job and earning a bit more cash. Mates rates is saving me around 3k... good news since the car has been off the road since 23rd May :P

the standard rb25 gtst rods are good for about 500hp I have been told

I would take that with a grain of salt personally.

GTR rods are good for 400rwkw no problem, i think some people have run them upto 450rwkw without seeing problems as yet in built motors, but the key there is the rod bolts are the stockers :O

oooOOOooooh f**k yeah :P

R31Nismoid, I will more than likely end up staying with the stock camshaft due to lack of interest. Depends on how much power I get from the dyno and if I am riding the line the decision will be based on what is the safest option.

Is that a 1.8mm head gasket or is my maths wrong? I hope you have a big f**k off turbo to make up for the total lack of response that will cause.

GTR rods should cost around $150-200. I bought mine for $150 and sold them for the same when I discovered my engine already had them. I can't say I was bowled over by people trying to buy them at that price either.

Cams will just help you get the power at a lower boost.

ps, I like your bonnet.

      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.
