R33 Rb30 Conversion


JNR24

Recommended Posts

Wow finally read it all, took around 2-3 weeks haha. Awesome thread!

Anyhow, I have a spare RB30 short motor if anybody is interested in adelaide. It's a S2 from an R31 and appears to be good condition. I bought it to do the conversion, but have since purchased a different motor to use for ease and because of money. haha.

Yeah, its all here minus the sump so if anyone is interested for a conversion just send a PM!

Brad, keep a set of CP RB30 9:1 pistons and Spool rods for me. Through sheer luck a 26 head and intake manifold dropped into my lap so I might as well build another and offer someone the gift of 26/30 goodness.

Hey guys. I made a topic out of this but havent yet got a a reply and thought this might be a better place to ask the question. I hope thats ok

Recently i got my fully built rb25/30 up and running after a year long build. The only untouched component in my engine bay is the fuel rail everything else is either aftermarket or had work done to it. I'm using a haltech e11v2 ecu & atm the car is load limited. Basically what happens is at 6,500rpm the engine will stop reving any faster unless the wheels are spinning in which case the load is taken off the engine and it will rev out. Its not a harsh limiter it just will stop revving any faster and the exhaust sounds like it flutters very fast. The ecu has an inbuilt rev and boost limiter but they are both set above wastegate pressure & the current rev limit.

I didnt relise until recently but i found out a few of my mates using different model haltechs have had numerous issues. I now know i should of cashed out the extra money and gone a motec but whats done is done. Rob at 101 is a really smart guy and he told me he'd be able to work it out eventually but the longer he spends working it out on the dyno they more my bill will be. I was hoping someone else might of come across this before and already worked out the answer.

The answer to what?

What's the question/problem?

have an rb30 twin cam in a 32 and would like to put a brake master cylinder brace on but with the different height of the motor i'm thinking the off the shelf ones won't fit?

what have other people in my position done?

Cheers!

I have a Cusco master cylinder brace and it all fits fine with the rb30 in there.

ah cool, thought u may have had issues with the different heights of the motor.

Where did you and scooby get yours from?

Do u have pics, i may have a go at making one myself.

Cheers!

Hi Ash, got mine from Jap auctions. I've got a spare Nismo one without the stopper you can have for $50 plus postage. Probably not worth making one for that price I just don't need it.

what exactly is the stopper? do i need it and will it suit a 32?

Well, my engine had its "dummy fit" yesterday and all the clearances etc checked. All good to be assembled next week. I'm starting to think i should of gone 280 cams instead of the 264/272 option after reading around the net. One thing that was picked up was i have a R34 RB26 head and i got cams to suit the R32/33 RB26 head for ease of finding a crank angle sensor later on. Well the HKS valve springs to suit my cams held 7psi less than the R34 factory valve springs. I now have aftermarket ones that almost hold double the pressure. This stuff is way over my head but by memory, the HKS springs held 38psi so the stock ones were 7 psi above that and the new ones (can't remember the brand) held 75psi. I don't know what these numbers mean but more is better i presume. The ATI balancer looks pretty too. I hope my stall converter is big enough for the T04z as well.

I am finding it hard to choose between the Haltech E11 v2 or EMS 6860. Any help from you guys would be appreciated. The car will be primarily a drag car. I am wanting to have a low boost level for 1st and then a higher setting for 2nd and top gears. Also i would like to run 2 seperate maps if possible maybe even 3 switchable seperate maps.

Cheers

Steve

Well mine is back on the road; but in run-in tune. :D

Couldn't be happier, i keep grinning every time i press the GO peddle.

Below is a few pics of the completed engine bay and the run-in tune. The boost is very responsive, and that's only controlled by the actuator (no bleed valve, EBC or restricters) Once i have completed 1000km, it will be wound up to 20psi, then the fun really begins :)

    • I've had a range of rear diff centres - open, viscous, helical, mechanical, welded, etc.   I can't go past a refreshed factory 32 gtr centre for consistent lock and street driving. The next step up for me would be the nismo 1.5 way , which likely suits you better as track sounds like the focus. Will chatter in carparks but its not the worst.   I have never tried a quaife rear diff, an option I've looked at before and might be one for you .....   Currently playing with an S15 centre at the moment and I hate it.  The transition from single wheel spin either side is just weird.
    • Honestly, I did think the PDM could do it and thought Haltech told me the pump didn’t like it. But after re-reading the emails and comments above, I clearly misunderstood lol.
    • I also run a CD009. I'm currently on a 4.08 and it's not great. I originally intended to run a 3.3 but had issues, more on that later. I'd stick to anywhere between a 3.3-3.7 as found in the 350z.  As for brands of ring and pinions, absolutely stay away from Speedtek. They are absolute garbage. See my build thread for more information on that. I went through two of there 3.3's and both had bad runout. They were paperweights and they have still yet to refund me.  I ended up putting in a Nissan 4.08, which was better then the original 4.36 but is far from ideal. I'm going to pop a 3.5 in this winter. I'd stick Nissan. I've also heard of a company "Neat Gearboxes" that makes them. Haven't tried them, but they can't be worst then Speedtek... 
    • You should Nistune the ECU, so you have freedom to use modern injectors instead of replacing with the same old shit. This is also required if you want to boost it up above ~200rwkW, where the stock injectors will be running out of capacity. Having said that, it is unlikely that the injectors need replacing just 'coz. If you imported it from Japan, the fuel should have been pretty good quality for the whole life of the car.
    • Just for a good chuckle. I received the new climate control yesterday and just before starting to remove my old one, I decided to try it again... it worked and has worked since haha. I'm keeping the new one on the shelf as I know it will repeat itself again at some point.
