R33 Rb30 Conversion

[Cubes]

Really depends what you are after.

I'm going to push upwards of 300rwkw maybe slightly over so I didn't want to hit 280rwkw and realise I should have done those forged pistons.

--

The head has been rebuilt, ported polished, the required angled valve jobs to suit the exhaust and inlet, cc'd & inlet valves deshrouded.

*make sure you get the seat pressure checked as some RB25 heads tend to lack seat pressure causing valve bounce at higher rpm and higher boosts, in other words don't buy it second hand and assume it will be fine*

The bottom end has had everything crack tested, blueprinted & balanced to 1g using a hienz balancer.

Forged pistons & 3 multilayer s/steel head gasket that has an O-ring setup in the 2nd layer.

Thats all off the top of my head.

Not really sure about drift, i'm not really in to that scene to be honest.

I prefer to try and be clean as possible around a track

Its good to watch for a laugh though.. When ppl loose it.

The bottom end torque should be good for drift but I would tend to think a motor that is a little more snappy like the rb25 with a decent sized turbo would probably be a little better. Not sure.

I'm basing that on my rb20t compared to a r33 making similiar power (170rwkw). The R33 was difficult to get sideways out of corners as it was very linear. The RB20t was very snappy and the hard hitting torque transition would cause the tyres to break loose easier.

Be interesting to see how I go with the opposite joel. Do everything except the bottom end. I have big faith in the RB bottom end

[Cubes]

I'm sure it will be fine.. The RB30 bottom ends are tough as nails.

Being at uni I wouldn't be able to afford to rip the motor out and rebuild it again if a piston went.

+ my other half would hang me by my............

[GTR-Ben]

Yeah I see your point.

I have all the tools, a hoist and don't have to study

[Trizae]

you're going to push upwards of 280rwkw with the standard RB20T Gearbox!? you going to upgrade it at all or just keep it where its at? how did the dyno test go?

[Cubes]

I'll let you know where it breaks and how it breaks.

Dyno is Tuesday.

[GTR-Ben]

I will probably run mine with a Rb20T box for a start also.. just waiting on the RB25DET box, or time to mod the RB26DETT box to 2WD.

me got a poor ecuze for a gb r33 one....bearing grind go for tune up in 14 dayz full boozt run

well I am outta luck for a rb30 block. I have contacted people for one. But they never get back to me. Sydneykid even offered me a built one. But to be honest I can't afford that as of yet. I'll go ahead and take the used block untouched offer.

Anyone?

thanks

Gus

P.S. I have posted every where and still no bites. Anyone please?

[black_32]

i hve heard a few diff things and wanna know i hve an rb20 with a stuffed bottom end if i got an rb30et bottom end could i swap everything over and is this a job for a professional

Hi, I think the problem is you are underestimating how much of pain in the ass it is to send an engine half way around the world. Customs clearance, quarantine inspection, duty declaration, sea freight organisation, packaging and road transport to the wharf etc etc. It's not so bad when you are sending an engine with some value, but is it the same amount of work for a $400 engine as it is for a $6,000 engine. In fact it is even more work because a freshly built engine will pass inspection easily, a dirty, oily, old, used engine is not so easy.

Plus I guarantee you that you will not be able to rebuild an RB30 (to whatever spec) cheaper in the US than what we can downunder. It's false economy, but your choice nonetheless.

It depends how well you are with your hands and head.

I found the conversion to be a little bit of a pain in the arse (little things like trying to find a 14mm welsh plug & spending half trying to get the gearbox on the back of the motor. It takes sooo much time.. Especially doing it by your self with the odd hand.

Expect the car to be off the road for 1-1.5weeks. I've cleaned everything replaced gearbox, oil water fuel lines/seals. Thats what has taken the time.. Then only to find 'ahh damn i forgot this better order it in from nissan'

I've been taking photo's along the way so I can document exactly what has to be bought or modified to suit the rb30.

Yeah your right again. :chairshot ( you hitting me) lol.

Then is it too late to send moeny for a built block? I still have to sale some other stuff before I can cough up for the rb26 worked head. Please shot me an e-mail at [email protected]

We still have to talk about payment method etc.

thanks

No you need an RB25 or RB26 Head.

The RB20 has smaller bores..

You can use most of your parts, but you need to purchase an RB25DE/DET head.

Not a job you really want to do all on your own, especially the bottom end, new rings and bearings etc.

Please go back over the last 70 pages and have a read..

The beast is alive..

The car idles and rev's as smooth as the RB20DET on the stock RB20DET ECU.

I'm unsure why Darrens R32 had issues, maybe the PowerFC base map is some how very different to the stock ECU map.

I've got a vid & audio clip of the start with only the dump/front pipe on, its not as loud as I expected. Sounds awesome with slight rev's as you can hear the turbo spool.

I will post soon.

bout time

now come over and put in my AVCR 230odd rwkw....mmmm

Awesome stuff!

I get my PowerFC tomorrow, so i'm not far away from starting mine.

Just a few small things, and running cooler pipes etc. :flamed:

[Cubes]

I was suprised how well the stock cooler pipes for the R32 bolted up.

It actually fits better now than it ever did.

Must say.. The exhaust note sounds awesome.

Should be run in within 2 weeks

[meggala]

great to hear the beast is finally alive joel cant wait till your drive results come in

meggala

[Cubes]

The stock turbo makes positive pressure by raising the rev's slightly and letting out the clutch

Its been a long time.....
