ah sweet as. yeah i think i do rember you. yeah my car is sitting at midas right now. dean is just finishing off the extractors today.

yeah you might see it out the hutt on thursday. i will have been for a long drive before then to start the run in as i will probly thrash it at some stage being around the skyline guys as they will all want to see what it can do.. lol

good to hear that your car is running again :P

yeah wazz i know thats the worst thing to do. but also nanaing it is just as bad. i have planned out my first trip in the car. will involve alot of accelerating and decelerationg and change of load as i will be going over hills etc.

i think i can have the 1,000 run in ks done in a week and a bit. if i have the time.

yeah definatly will try to get some audio of it. probly will need to change the rear muffler from the stock turbo one im running now. seems to have good flow and is nice and quite.. just a little ratly i think.

fuel consumption

hwy driving 9.5 ltr /100 km and better ( 10.6 km / ltr )

city driving 10.8ltr /100 km  (9.2 km / ltr )

Gawd damn.... Doesn't appear to be any difference in fuel economy between turbo and N/A.

I've only just had gtr injectors and a new genuine 02 sensor dropped in, trimmed back the pfc fuel correction to 58.5%, instantly it began getting 11.6L/100km's.

Had it all tuned up and now gets a nice solid 10.6L/100km's of city driving.

I'm pretty much just cruising around 90% of the time, occasionally I give it a little squirt that has it turning the rear's easily in second gear. :)

So it is driven fairly easy.

Prior the old crappy 260cc injectors were causing hard starts and slight flat spots on the tip of the accelerator pedal. Fuel economy was wofull. ~14L/100km's.

On the stock ecu when the injectors were ok it was managing ~11.1L/100km's.

cheers for the advice. especialy cus im planning on starting the car on thurs. will definatly be an interesting time. have to rember to keep using the brakes. not the engine as i usualy do.

yeah the fuel figures will be interesting to see how it all pans out.

ok well i got the car back yesterday. iv had a few little problems. all but one i have delt with now.

the car cranks, has fuel, injectors are working, not sure about the coils yet.

but the problem is the ECU is coming up with the error code 34. so that is about the knock sencers. that doesnt suprise me as the loom was cut on only the knock sencers. but i have solderd it up and still no luck. im really frustrated as no body knows what to do to fix it.

i have attachd a pic of what im talking about. the brown wire has the clear wire inside. but it has silver wire on top so i dont get how it works and what the silver wire is there for as its not grounded on anything. and it just stops abruptly(checked that on the rb20e knock sencer wire.)

she lives!!

oh how good it feels to have power :D even tho i can only rev to 4000rpm its still damn fun. well for the 5mins i drove it.. oh and the mean grunty sound even tho it only has a stock turbo muffer on there.

then i found a coolant leak under the front of the inlet manifold. so thats off now. gota replace the gasket and the front stud as the thread is munted. but that should be done tomorow.

dyno is in 2weeks(18th march) and on the 19th im taking part in some 1/8th mile drags.

oh its starting to get exciting. mmm rb30 goodness :)

yeah i used to have a dirty old rb20e. the jump is massive. i might try get a drive in one of my mates gts25 just for comparasion. or let him take it for a spin to compare.

im keen to see how the dyno gos to see what the torque and kw are.

it will definatly be drivable round town easy. now i just need to get the inlet manifold on. check for leaks then i can start driving again :)

Hey I was thinking of doing this conversion on my R31 since DOHC is always better than SOHC, but I just want to know if all RB25's have VVT and whether you can run it without the VVT? Also do you need to run it from the RB25 ECU or can you still use the RB30 ECU?

read the r33 rb30 thread.

r32 heads bolt stright on. that thread is in force induction.

you can make them run with out vvt. just change the inlet cam. but you still have to run external oil feed and drain.

ok heres some sad news :P

sounds like my rb30 has screwd the big end bearing after only 20km of driving. yeah its worse then a rotor...

the reason why is the engine lost all its oil out of the front of the engine. presumably around the crank oil seal. so it should be fixed under waranty. argh stupid engine builders!!

so ill probly wont be able to dyno the car or take it to the 1/8th mile drags as it probly wont be fixed in time :(

all i can say is the little bit of driving i did today was freaking awesome. i cant wait to have it back and running. it sounds so nice too :O

read the r33 rb30 thread.

If you mean the one stickied at the top, that thing has 166 pages! Can anyone just tell me if the RB25DE ecu is needed to run the RB30DE. I'm assuming so since it is DOHC and it has the cam profiles in it.

if your going to not use the vvt you can use a rb25de ecu outa a r32. im using vvt and i was running a stock rb25de ecu from a r33. bear in mind you will need the right loom for the ecu.

Lol forgot about the loom. Now I'm not so sure if I want to do the DOHC conversion since there'll be a lot of wiring involved. Think I might just go down the RB30ET route.

Guess it depends on how much wiring there is to do and how hard it's going to be and also how long the car will be off the road.

Is there actually much work involved in having the VVT?

    • Mixing things up - installed some leather recaros to match the leather seat covered rear seats. Interior looks pretty schmick now except for some slight wear on the steering wheel which I will monitor and address if it becomes worse or actually noticeable!  
    • Didnt realise RB's had more then 1 head.
    • 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!
