Before you go ahead with asking a million questions, it's best to go and read all the info that's out there so that you can get an idea of exactly what it is you're doing.

Here's some stuff that may help.

There's a lot more info out there, you will benefit a lot more from learning about it yourself and actually understanding it, instead of being told what to do.

Further to that, you will also be needing a gearbox (RB30 gearbox won't last 5 minutes) and if "paying through the teeth" is an issue, then it might be worth rethinking your plans.

This isn't a cheap conversion, and as you go along, more costs will become involved.

Do all the research first to find out if this conversion is actually within your budget before you start buying parts.

You'll be looking at around $6000 worth of parts (that's not including turbo or labour)

how did you come to $6000, I have found out info on how to go about it, and I am able to do it myself, all bar mapping computers and stuff. I can put the head on and install just about all the intake, theres just a few odds and ends Im not sure of

HAHA that article is a POS. ****edited by PranK (no business names please)**** Then how come they managed to overtighten an idler bearing bolt on my engine and blow the fu.ker up. As well as having 2500 on the coil cover, and rb20 on cam belt cover??

As far as costs, the rb25de (non vvt) head + intake manifold was $750, recond the whole lot + porting was ~$900. The rb30e bottom end is $100 (with cracked head) Recond' (Acid dipped, honed, full balance, crack test rods & crank,) ~$1800 + $1400 for forged pistons.

All up about $5k - Without labour to fit it to the car.

If u use non vvt go the rb20det wiring loom + comp (it didn't have it from factrory) If u use vvt go rb25det wiring loom + comp (it comes from factory), but not worth the hassle IMO.

Prices will vary from state to state, and also depend on availability of parts.

I did read that article, but I had found one with more detailed info. I just dont want to start unless I have all the info. Connecting the computer will be tricky because I dont have info on the 25 comp. Also since the RB25 has a crank angle sensor you dont need the distributor, so what do you do with it, just rip it out.

run the rb20 comp & loom - no need to build it with vct.

whats VCT and how can I run a 2litre computer on a 3litre engine

read the r33 rb30 conversion thread in the Forced induction section.

Its variable cam timing. I have an r32 (ie rb20) the rb20 comp is used and runs everything as normal ie injectors etc.

Read the thread - it'll answer all questions, and then -Joel- 's DIY rb30 guide. Then ask some q's in that thread
