JNR24 Posted November 10, 2004 Author Share Posted November 10, 2004 Ok quick question, Does the R33 manual transmission input shaft go straight into the RB30 Crank?

Cubes Posted November 10, 2004 Share Posted November 10, 2004 It does if you put an Rb20/25/30 spiggot bearing in. Darrens (Bl4ck32) RB30 had a flywheel attached as it was from a manual car. But to his suprise it still had the automatic spiggot in there. The Auto spiggot hangs 1/4 out of the crank. The Manual spiggot sits all the way in and you can only just get a finger in there. The Auto you can almost fit a thumb in it. I posted pics a while back. Unsure if it was in another thread or in the RB30 thread. I've been getting a little bit of reversion occuring with the stock rb20t turbo and std. N/A cam specs. I've advanced the timing quite a bit 25degree's to help smooth it out. Now I can only ever so slightly feel the bog down only under certian conditions. Its going on the dyno Friday for a tune so it will be interesting to see if it gets rid of that afm cut I'm getting at around 10psi. AFR's are fairly rich dipping in to the 10's and it only gets richer as boost increases.

Sydneykid Posted November 10, 2004 Share Posted November 10, 2004 I have a question.I'm worried about running the engine in with all the aftermarket parts i'll be using with a power fc on a standard rb25 tune. Would it be better to run the engine in with the standard cams and injectors and install the pon cams and 740cc injectors later. (valve springs will be already installed. Hi Alf, I would stick it all in, that's what I do. It is so much easier to do on the engine stand than once it is installed in the car. I simply take 700 cc vs 370 cc out of fhe master fuel correction on the PFC Commander (about 45%). Remember to do that every time you turn off the engine as the Power FC does not retain master corrections. Hope that helps:cheers: Link to comment https://www.sau.com.au/forums/topic/15420-r33-rb30-conversion/page/79/#findComment-1082741 Share on other sites More sharing options...
25t Posted November 10, 2004 Share Posted November 10, 2004 joel i must have got lucky ,i didnt change the spigot bearing ,did measure though,just bolted the gearbox up. car is sold now ,new owner ran at drags 2 weeks ago did a 12.8 in street trim Link to comment https://www.sau.com.au/forums/topic/15420-r33-rb30-conversion/page/79/#findComment-1082761 Share on other sites More sharing options...
Cubes Posted November 10, 2004 Share Posted November 10, 2004 Not a bad time.. What were the mods? ECU? FMIC? Exhaust? Bit of boost? On std. street tyres?

Guilt-Toy Posted November 10, 2004 Share Posted November 10, 2004 Can you not do this in a more permanent way?.. seems odd to do it every time you turn the car off?? I dont believe there is anyway in the PFC Hand Controller to do this. We looked for ages for this option and the only way i could take a certain % of fuel out of the system (50 psi base pressure in fuel) was to go into the INJ map and take out 15 press's on EVERY load point which took me about 2 hours Link to comment https://www.sau.com.au/forums/topic/15420-r33-rb30-conversion/page/79/#findComment-1083056 Share on other sites More sharing options...
GTR-Ben Posted November 10, 2004 Share Posted November 10, 2004 Ouch.. i'm going to have fun doing that. Do if you were to go and setup the INJ map with a certain % more for size of your injectors (444-600cc) it should be a more permanent fix..?

Going though the maps and changing 400 load points by the same amount is a waste of time as you have to tune it properly soon anyway. Guessing a single % for the whole rpm and load range is not a good idea. If you are going to carry out minor upgrades often, then you should look at a Datalogit, it's very simple then.

Dayco belt. You don't need to do the tensioner like this also. I think 2 tensioners in the stock position would be fine.

I like the second (high) tensioner mount, same as this. Personally I think the tensioners get too close together when they are both mounted low and the teeth face each other. Any slacknes in the belt or a bit of whip and the opposing teeth will rip each other to pieces as they are travelling in opposite directions at big RPM.

Any slacknes in the belt or a bit of whip and the opposing teeth will rip each other to pieces as they are travelling in opposite directions at big RPM. I see your point.. I was thinking of the OS RB30, they have the low mounted tensioners, but then again, they have a different sized belt also.
