And parts for VVT and gaskets ??

He may have got a front mount intercooler installed also i cant remember

All top end gaskets are included in the VRS kit.

headg,exhaust,inlet,plenum,rocker cover etc.

I did forget to mention welding/putty the head to mate up to the RB30 block.

Not sure on the price of that but it isn't much.

+ other parts for the VCT.. $50 for the oil feed line max.

Unless he had a wizz bang ecu 7k for a simple head purchase, head bolton & drop in to engine bay is rather expensive.

Hello everyone

I am a registered newbie to the board, I have been reading up on this thread fo some time now. I am finding a hard time locating someone that would sale and ship a rb30de series 2 motor to the good ole USA, california. Does anyone have a block ( no tranny, clutch, nor head ). I want to do the build up myself just as it was detailed in this thread. Also also the websites posted on this thread to whom those that have done the conversion already.

PLease let me know.

Thanks

Daiso

I can organise to get a RB30e sent to the US if you pay for it. My friend has a Workshop he can send it out. Go through him PM me if you are interested

When you think about all the hours that it takes to do this conversion you might not think 7k is that much of a rip....

He only uses good quality fittings and he drills the head and uses a plug. mods the block to use the standard oil cooler and does not dodge anything up.

oh and this was about 2 years ago now

He did mine for a good price.. his customer paid the bill and was happy with the result

Some mechanics charge up to and over $88 an hour. Remember that.

Hi Guys,

I have a major concern about the rb30 bottom end.

What problems would 600 hp + rb30's have with respect to the bottom end, you guys have pretty much covered pistons,rods and crank but what about the main caps?.

The RB26 uses a girdle intergrated with the main caps?, The rb30 main caps look no where strong as the RB26. Nizpro made a 600hp RB30DET which they made up a billet girdle/main caps similar to an RB26, this looks so much stronger than standard.

I've only ever seen this done to an RB30 once, have u guys seen these kind of mods done to other RB30's?

[Cubes]

Your best bet would be to head over to the forums of www.calaisturbo.com.au

There's a few RB30DET's all with big turbo's and huge arsed exhaust a/r's.

I have no idea what you are looking at Alff, but there is very little difference between an RB30 main girdle and an RB26 main girdle. Simon's RB30 with the billet girdle made ~1,000 bhp on the engine dyno.

We have built a 900 bhp RB31DET and it uses the standard RB30 main girdle, our race RB31DET makes 650 bhp all day, every race and it uses the standard RB30 main girdle. We built 5 RB30DET's 2 years ago and they are all running perfectly, the LOWEST power output from those is 650 bhp, the highest 780 bhp. I pulled one down for inspection 6 months ago and it was perfect, crack test, sonic test straightness, the lot.

Bottom end strength well proven by hundreds of RB30 runners all over the place since 1986, too much evidence to ignore. :cheers:s

Thanks SK.

Once again you have made things loud n clear.

I can just picture some geek dude from sydney laughing his head off at all us idiots building these engines and blowing them up all the time

Hi,

I was woundering, would there be much different needed to be done instead of fitting and RB25 Head, fitting an RB26DETT head? Sounds like there is alot of potential and I would love to have a new weekend project now that the R32 is on the road now. Would there be any other modifications to the head or the block need to be done on top of what you guys did with the RB25 heads or the same?

Thanks, Chris.

[riceline]

Yes there are bonnet issues. I have a series one and the bonnet rubs on the plenum

I would assume that this will be the same with the S2

[-=Trizae=-]

just a quiery can all this be run off the stock RB20 turbo? non high flowed? and with a setup with the stock RB20 turbo etc how much power is being put out? reason i'm asking is so that I can run in the engine with all the standard RB20 parts like ecu turbo etc for a bit then slap on better supporting hardware like cooler/injectors/Z32 or q45 afm/turbo etc i'm only really after around 220 - 250RWK and would the Rb20 transmission support this power output or should I just get the 25 transmission? and what about a VLT 5sp tranny will that be able to be bolted on and what are the differences between the VLT tranny and RB25/20

I reckon the RB26 top end is easier, no vvt to worrry about.

[Bl4cK32]

apart from different head stud sizes...not that im being a bitch, seems this thread is a constant re hash of the same info...

People seem to ask the same q's over and over....thats why some may not get answered...

end/rant

[riceline]

Has anybody in QLD got there 30's enginered yet?

I have got rego coming up soon and want to get a mod plate for it so I can update my details.

If so where did you get it done?

[skyline]

I can understand having issues with the plenum,however i'm using a greedy inlet manifold with a sub zero 80mm billet throttle body.I'm more concerned with cam cover issues,pretty much everything else should take care of it's self????
