yeah they are cheep as chips. mine cost me $100 but nah iv spent enough on the internals of that motor getting it ballanced, pistons swapped over etc.

the engine place should fix it under warranty due to there screw up and all the oil pissing outa the crank seal. it must have pissed out like 4-4.5ltrs of oil in 10km

im used to not having a car by now. its been like 3 and a half weeks now. whats another week or 2?

as long as i have it back in time for the drags im happy as iv paid the non refundable $$ for it :)

cold fusion:

the wiring isnt that much hastle. well for me it wasnt too bad. running the loom isnt hard. in my r33 there was 2 or 3 wires that didnt match that stopped the car from starting. an auto sparky should be able to have it sorted for like 400max?

there isnt that much work in having vvt. well i suppose there is. welding up the front oil gallary, runing an external oil feed. thats the main bit of work. im pretty sure thats all detaild in to the rb30 pdf file.

dondesoto has a rb30de running vvt in a r31. have a look at post 8 on page one.

I think the wiring in my case will be more difficult as it will be going into an R31 which probably means most of the wiring is different. Welding the gallery shouldn't be too hard for me, the taps might be a little harder. Will probably need dondesoto's opinion on this.

$100 for the block is really cheap. Didn't know you could get them for that much. Where would you get just the bottom end (block, pistons, rods, crank, sump)? Wreckers? Engine reconditioners?

Thanks for all the help guys.

i got mine from a wreakers. my $100 was for a short block. i was lucky and i got one with the tubo fittings(incase i ever want to go turbo)

the wiring is workable as proven by dondesoto.

the welding is alloy as you have to weld the head. not the block.

send him a pm to ask further questions about wiring etc. from what i have read he did most the work himself.

I think for all the trouble it might just be better to get a RB25DE without VVT and just use that. What ECU would I need to use if I were to turbo that setup? R33 RB25DET?

Last question is what is the difference between the RB30E long and short block and do you know what the short block comes off?

if your gona talk about rb30det you need to go through that sticky as that has all the info. use r33 turbo computer with vvt head. rb20det for r32 rb25 head. the only rb25de head that doesnt have VVT is R32.

im pretty sure you have to run an aftermarket ecu to keep the turbo happy

the short block is just an rb30e with out the head on. a long block is with the head on. they still come from r31 skylines or vl commys

if your gona talk about rb30det you need to go through that sticky as that has all the info. use r33 turbo computer with vvt head. rb20det for r32 rb25 head. the only rb25de head that doesnt have VVT is R32.

im pretty sure you have to run an aftermarket ecu to keep the turbo happy

the short block is just an rb30e with out the head on. a long block is with the head on. they still come from r31 skylines or vl commys

So an R33 turbo ecu for a RB30DET with VVT and a R32 turbo ecu for RB30DET without VVT.

I was thinking the stock computers might be able to handle the corresponding stock turbos or maybe something a little bigger? Could it be because of the larger displacement the mixtures will be wrong and need to be corrected with an aftermarket ecu??

for run in you can use stock ecus. but you still cant hit boost.

as i said before. i dont know alot about turbo rb30s cus i was never aiming to build one. rb20det ecu can be chipped so it would handle. aftermarket is best.

cheers eug

yeah it sucks but there isn't anything i can do. it was acttualy knocking after like 5kms so it musta been pissing out the oil. i didnt see it was leaking oil due to the fact it was pissing out the coolant.

it also means i can get the coolant leak between the inlet manifold and the head sorted too.

but argh more waiting!!

i should be able to find out whats happend and what needs fixing on tuesday so i guess thats D-day

all i can say it is well worth it and im pleased with the engine's power and delievery. yeah i cant wait to dyno or get some drag/circut times either. ill be sure to post them up.

now i know what dondenoto gets to feel everytime he drives his r31 ;)

GOOD NEWS, sounds like the bearings will be fine. the oil was leaking outa the top fitting of the external oil feed due to me not doing it up tight enough. but it felt tight to me when i did it cus i think it was catching on the back of the cam cover back plate. stupid engine reconditoiners telling me that if they did it it would cost me more.

so that means the rattle is supposed to be somthing to do with the clutch/flywheel area. so that means the gearbox has to come out :) more $$ down the drain but its another thing that will be my fault most likly.

oh well. moral of the story is: wait till you have all your parts, dont rush, and make sure you torque everything up that needs too be torqued as thats probly the cause of the knocking sound.

should have the car back running perfect on friday all going to plan *fingers crossed*

yes im thinking of doing it to. only prob is i got a VVT head on my car. Anyone got a step by step from start to finsh on how to do it. i mean even how to prep the block for the new head.

That would b a good idea for somone that has done to make.....

people would pay for it.... including me

also what happens when you goto rego and they check the engine numbers Wouldnt they be diffrent??

if you get a new RB30 block you can *ahem* stamp your old engine number onto it :D i've heard of people grinding and sanding back the old one and *ahem* printing the new one one.

getting the vvt to work is pretty much the same as having it done with the RB30DET hybrid (check the turbo section for this) basically all the fundamental principals in building the RB30DE can be obtained from the sticky in that thread... (its a looong read over 100 pages - so be prepared to do your homework)

hey sorry guys been a while since iv been on the net.

the rb30s going great.. well except for the suspected cracked headgasket.. but thats not a biggy cus its only leaking oil down the side of the block.

in NZ there is atleast one place that modifys the vvt head to fit it. R.I.P.S is who i got mine through. hes well knowen for building high power stock internald rb30det cars.

i havnt been pulled up at all for my engine as it still looks like a stock engine. just a little taller. but i think NZ is a little easyer on cars.

im just looking in to some reground cams now as i only want to take the head off once if i can help it. so might also look at some minor porting and polishing at the same time if i can afford it. then probly an ECU and a few other things. im also looking for some parts to custom make a hex throttle setup.

  • 4 weeks later...

yay i finialy got the chance to go down the 1/4 mile..

started off with 16.3s. then i got down to 15.5 at 93mph on a unpreped track..

because of the lack of traction i was only doing 2.6sec 60foots

didnt help with running a single spinner at 2.5degrees camber in the rear. oh and running with the 18s on...

all i can say is bring on the 2way diff and reground cams!!

your mph indicates a much faster time.. something like low 15s or possibly even a high 14.

i reckon an LSD from another R33, and improved launches, maybe some 16" rims and tyres and you'll be running heaps better

Congrats on the time geoff, you should be able to get those times down with some better tyres and the correct setup etc, i was there on sat and saw ur car parked next to crux, i was in the green ford BA xr8, it was a completly shit day and a waste of a trip.

Yours cars lookng great man!

    • 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.
