R33 Rb30 Conversion

[bluegts]

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!

does anyone know where i can get a smaller aftermarket cranshaft pulley from any ideas?

[GTRgeoff]

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.

[Spoolup]

Always in stock mate.

How did you luck on such 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?

[r_speedfreak_r]

my question is why is the ecu stopping the car from reving any higher unless the wheels are spinning and how can i fix it?

[mr_rbman]

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!

[Scooby]

on a 32 GTR there is room if you use a Nismo one that is quite steep at both ends and gives some adjustment. not sure about GTSt.

[bubba]

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!

[bubba]

Got mine from Nengun, I'll take pics later if I remember

[Scooby]

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?

[Scooby]

Ash I'll PM you as we're far off topic now.

Has anyone fitted a high energy HE2112 VL 3.0L Commodore Super Pan $458.53* into a 32 without having to use a custom made front sway bar?

A few pages back, Al had problems with his HE8124 Pro-Circuit 3.0 VL/Nissan, 4 Gates, 7L, P/Up clearing the sway bar.

[RB120WHY]

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

Have you considered an Autronic SM2 or SM4? Do you know if the installed height of an r34 head is different, as that could explain why the r32 springs had such low seat pressure?

[2BNVS]

autronic sm4 all the way, but then im bias as i use it heheheh, i luv it

[Al]

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

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
