hey all

as some of you might of heard, in very unfortunate circumstances my sil caught on fire and melted a engine loom, and long and short of the short is it cracked a ring glan and then went down hill from there... so the poor lil 20's days are over :(

but from bad comes good....

and has finally given me a excuse to a RB25/30 :P

so here is what I have so far for the build...

(only started collecting parts only bout 1-2weeks ago)

- RB25 S2 Head

- RB25 Loom

- RB30 S3 Bottom end

- ACL Race Main Bearings

- ACL Rod Bearings

- ACL MLS Headgasket

- 2x Tomei Oil Restrictors

so this is now whats on the to get/do list:

- Boring, Blueprinting etc... on rb30 bottom end

- Arais Forged 20"tho Oversized pistons

- ACL Race Rings

- "x" Forged Rods

- Tomei Pro Cams (264 inlet, 272 exh)

- Stronger Value Springs

- ARP Head Stud Kit

- ARP Rod Bolts

- CNC billet rb30 crank collar

- assorted earls fittings and braided hose

- CNC Powertune RB30 Oil Power gearset

- Gates Timing Belt to suit 25/30 combo

- Custom Oil Drain

- New Water Pump

- Send my turbo back for the new one :D (GT3076R .84r)

- 50mm ext gate (currently running a KKR 38mm)

and thats all I can think of so far...

aiming to have the donk done by june-july... as there is a fair bit of coin right there haha!!

but 3 or so months anit long to wait :)

but if you have any suggestions fire away!!

cheers

N1GTR: hitting the streets on permit that is, since mine is a track car!!! :P:(

I enjoy the old permits tho!!! its great fun!!

doing a CNC billet set of oil pump gears that are custom made to fit the std pump surround... but the gears itself are alot stronger and better..

and yes ill be doing a enlarged sump as well...(its similar to the high energy style ones)

and have had a chat to my engine builder and have decided to go with 40"thou oversized pistons, which brings it to 3.1ltr :laugh:!!!

and we are going to piss the vct off as well.. n run some tad smaller cams... and some adjustable cams gears as well

here is a pic of the car when it had the rb20 in it..

(mine is the blue s13.5)

Looks like a great build, i would recommend running an external oil pump, and dry sump it or rear sump it so you can lower the motor.

yeh i would love to run a ext oil pump but its the cash,

donk will fit in sweetly man... just wait and watch what im going to do when the time comes to slide it in...

yeh started to slide man, only been out 1 n a 1/4 times on the track

and was just starting to get a grip of things then the mis-happen of the engine loom melt down..

oh well now the power will be nice and responsive and will be easier to steer without having to be trying to bring it up on revs...

good work mate, i have been for 3 years now haha. i cooked a loom too when my engine blew and oil seal and caught fire on the track. you definately will have more response form the 30 vs the 20 it will be a big difference you will love it.

      Unpeeling the Orange

      By MBS206 · Posted

      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.
