Just thought I would bump this 20 year old thread because the Skid Factory have just posted up a video summarising a lot of the content, format might be more familiar for newer members

fyi guys, Well yesturday i picked up a RB30 for my conversion into my R33. I will be using my RB25DET head on the RB30 block. So i started stripping the motor down, pulled the crank, pistons, girdle

Lets see what r33_racers failure was caused by before we go jumping the gun.

True, it may not even be that.

But while on the subject, does anyone run any 'engine kill' devices that detect low oil pressure and cut ignition to help save the motor? Is there a separate device like this available? A light on the dash doesn't give much time to react when at high revs, but perhaps a sensor to trigger ignition kill would be the go...

I've thought about a warning buzzer, not sure if killing ignition is the way to go, probably just better off with a buzzer so you can drop it in neutral asap. Providing you don't forget about the buzzer, it goes off and you think wtf is that, by the time you remember its too late anyway. :laugh:

Kill ignition and it may lock the rears mid corner or something silly.

mate runs an engine kill switch like the one suggested on his sprint car, with over $60K in the engine, as soon as the oil pressure drops, it cuts everything.

with our cars it might ne a little harder than the carbied V8.. as you have to bypass any chance of a turbo timer working etc, then power steering and where you are.

but i am DEFINATELY going to run a switch to a specific light (autometer pen light for example) that will be direct line of sight. might not save the rebuild, but you wont go seizing anything.

yeh i think motecs and autronics have that feature built in, if something goes over a preset warning value it shuts off the engine completely to save it from harm. I know alot of sprint car racers and even circuit racers have a kill switch hooked inline to the oil pressure switch which craved is talking about so it kills the engine if pressure drops to nothing. I think we wish we had that now haha >_<

Well my motor is nearly ready to go back in my car so hopefully thursday/friday the rb30det will be out and getting stripped down....we found a strip of steel/tin in the oil, looks like its from a bearing... :P

Oh also cubes...things we would do differently... Well our tuner wants us to run a flat 8:1CR. Id like to run 9:1, but they like it lower to help keep the knock down, so can run more timing and boost. Will definetely do all the oil control mods that SK listed properly, instead of letting my old man half arse them cause he thinks he knows better haha, umm defintealy run conrods with oil squirters and thats about it so far that i can think of. Will probably come up with more as we put it back together.

quickie -

what engine sealant did you guys use on the replacement whelsh plugs .. i have a black sensor safe engine sealer i used on my bike, would this suffice?

or something like a tri bond sealer be best?

      CD009 RB Conversion

      That's the most absurd thing I've ever heard. I would go cut bellhousing over that monstrosity of a flywheel all day, every day. It puts a lot more mass further from the last main bearing. I've had nothing but problems with Collins in the past and refuse to ever buy their products again. I would not trust anything they tell you. He's playing his salesman card.  I'm currently at 640whp on a mustang dyno (~770bhp) with the intentions of running E85 and a lot more power this upcoming spring. Cheers,

      Nah, it's not the reduced knock margin. It is a direct mechanical effect of having to initiate the combustion earlier, while the piston is still rising, which starts to exert combustion pressure on the rising piston earlier, making the rest of the engine work harder to finish driving the piston up to TDC where the combustion pressure stops being a negative and starts being a positive. Your modern engine that only needs ~10° to make MBT doesn't waste the other 10 or so degrees of crank rotation. That's almost all of it. The difference in knock margin might go either way. Remember that modern engines to which you are currently comparing the long tractor engine (the RB) are now running super high compression, direct injection, tricky cam control and maybe even cylinder pressure sensors. You're not comparing apples with other fruit. It's apples and sea weed, or some other evolutionarily primitive vegetation. And remember, squish only really comes into play at the very end of the stroke. It certainly does good things, but it is not the biggest contributor to what's going on. It is quite possibly much less important in 4 valve head than 2 valvers also, because there is so much less squish available to a 4 valve anyway.

      Food for thought, a longer stroke motor would need less ignition timing vs. a shorter stroke motor requiring more ignition timing.

      Thanks Duncan, HART is only 10 mins from me (I did my bike license there), it'd be awesome if it ran these types of things.  Sutton Road does look good and they take fewer cars than SMSP which is good.  Surely you have enough land to lay a few million tonnes of concrete and some sprinklers D?

      I thought an engine that needs more ignition timing to make power is going to result in less power due to reduced knock margin? More time for the combustion to propagate -> more time for it to heat up the rest of the mix to detonation.
