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. :D

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)

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.

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.

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 :P

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
