Rb30det Or Rb20det?

[joe2548]

Theres nothing wrong with having a RB25DET head, the VVT is a peice of piss to get going, if your going to all the effort of building the rb30det, there are a lot harder issues you have to deal with.

Im not to certain your bearings and gaskets are included in that price, i think thats bullshit. My rings were around 150 trade, gasket set 200 trade and pistons were going to be 550. Thats staff discount also not trade so cost + GST

SirRacer I don't GIVE A F**K if your certain or not mate. Were you standing over my shoulder when I bought the kit? Thats what I paid complete rebuild kit, it was around $440 Pistons Rings Bearings and Gaskets. It was staff price and I am not sure theyre "Race Series" or not thats what I asked for, I know theyre standard type cast (which I stated) and NA compression ratio pistons. Why do you have to come on here and say I am talking shit, when you obviously don't know.

And yeah most the questions on here have been examined in great depth on the sticky post R33 RB30 Engine conversion thread. Its just hard to find any information theyre because its too long, and to be honest even though I should I couldnt be bothered reading it all either!

joe2548,

Dropping an rb30 in is suprisingly straight forward.

The only mods required are engine mounts, dump pipe and power steer bracket. + the vvt if you go the rb25 route.

I would have to say the vvt is the most indepth and most fiddly to do.

The way I look at it.

R32 - R32 RB25DE or RB26.

R33 - R33 RB25DE/T or RB26.

Unless you struggle to find an R32 rb25de head then I wouldn't bother with the r33 rb25de/t head UNLESS you simply wanted to.

R32 RB25DE head in an R33.... You would have to have rocks in your head.

RB26 is obviously the best option in all cases.

With regards to buying items...

It is cheaper to buy a complete rebuild 'kit' rather than buying individual parts.

The same goes for rebuilding your head, grab the VRS kit that contains all top end gaskets/seals and valve stem seals for around $280 odd.

Try to buy the valve stem seals on their own and you are up for $330. Go figure.

The RB30DET thread really is a too large. It contains a LOT of inaccurate information that only confuses one. When it first started out almost nothing was known on the build up so some recommendations are obviously not 'the best' that could be offered.

Hell we are even still learning now... i.e CP pistons being an almost perfect choice for the RB30DET.

The rb30 guide that has been collated is still updated.

It covers what I consider to be the most important to you and even an engine builder that hasn't done such a build before.

Guys, the Cubes guide (in his sig etc) or the RB30 conversion thread has all the info

this is almost going to be locked as its just repeating what has been posted time and time again.

Yes the RB30 sticky is long

Yes the RB30 stick has a lot of information that is over your head

But at the end of the day. Grab a beer, sit down and start reading.

It might take you the better part of a week, its very long.

But it does have everything you can think of, and then something that you are yet to think of as someone else already thought about it

RB26 IMO not the best option. No-one in thier right mid would put one in with stock turbos.

So you add anotehr 2.5-3k onto the purchase price of the motor right away

Reading the rb30 sticky now, man 186 pages of info, easy to confuse a new comer to the scene like me. I think i will start reading Cubes' guide, seems alot less double talk and not as much useless info in there! (now when i say useless i mean useless to me, as it is way over the top of my head!) Thanks Cubes!
