Putting an RB25DET in an R32?


Recommended Posts

I am considering doing an engine swap in my r32 and was wondering if anyone here has completed a RB25DET - R32 conversion.

I would like to know the costs, both for labour and parts, and a rough idea of what an RB20DET, manual goes for so i can recoupe some costs.

i have just bought an rb25det for a reasonable price an all up it is easy to do it yourself job cheaper aswell but depends on your decision so anways provided you know what ur doing i sold my rb20 for $3.500 an theres nothing wrong with it. If u can always check up on prices and is always helpful to ask i have an r32 gtst and you will porberly need an r33 if u want to add power mods (stupid answer) to it after the engine swap turbogearbox for ya ride but all should be sweat sorry to breif

hope this was helpful

life is what u make of it not how it treats you

$3000 for the RB25DET (just jap)

$1195 for the RB20DET

You'll need a stronger gearbox (RB25) which is about $1000. Optional but recommended to replace the front brakes with R33 brakes as they're slightly bigger (and better).

It'd be cheaper to buy a R33 front cut. Atleast that way you'd have some extra stuff to sell like the headlights and quarter panels. I'm not too sure how much they are as I can't find a price anywhere on the net (not really trying).

Labour? a few slabs if you do it with your mates, you'll learn a lot from it as well.

If you're going to get a mechanic to do it, might cost about $1000 if nothing goes wrong...

I'm in the process at the moment, although my RB25DET is from a Stagea AWD.

The engine set me back $3700 (complete with auto trans! - any one want a AWD auto?), and I'm planning to run a Wolf3Dv4+ ($1600). Then there was a $1G for the lightweight flywheel and clutch setup (which I would have got anyway).

The engine didn't come with a coil ignitor module (its apparently built into the ECU), but I managed to source a reco'd one from Petroject ($350).

Extra couple of hundred for ancilliary stuff like relays and wiring.

I'm hoping to do most of the work myself, just renting space to do the job. So I guess I'm looking at around $6G all up. Plus tuning time (for the Wolf).

If you get a half-cut, it might be a bit cheaper, especially for a RWD-only cut. And you get all the electrics you need, ie ECU and loom.

RB20DETs aren't worth that much, maybe $1G if everything is attached.

    • Superpro are fine. There are some applications (R32 FUCAs for example) where they are no damn good, but typically for any normal suspension bush, they are fine. Some people will complain of them making noise. Some people will complain of them collapsing. But many of those can probably be traced back to not properly lubing at install or other installation problems, or possibly other problems elsewhere in the suspension that put additional load into particular bush. And for the legit complaints? Meh. Deal with it. I had to replace the poly bushes in my R32 FUCAs every year. The real issue is that I am sold on the idea of adjustability of at least upper arms. So I only have spots for poly bushes in lower arms these days, as everything else is either hardened rubber or spherical steel.
    • Suspension really is complicated.... All these considerations are making me over think it all. Again. I reckon I'll wait for SK's response on his coilovers, and go from there. Though if I go MCA, I'll have to decide on whether the extra $600 (voston comforts $1890, mca pro comfort is $2490) is worth it. Just something soft and comfy, yet firm enough when required at the track or a casual old pac drive for a pie... Otherwise, anyone have experience with SuperPro bushings? Needing to replace the bushings on the suspension department... Will probably keep the oem uppercontrol arms etc, and just replace the bushings. 
    • yes you are right, indeed it is for information only.  there is not much difference being at 9 or 9.5 or 10.  but when I see that you have to plane the block by 2mm if you have taken (example) CP piston which means that you end up with an 8.2 with the rb26 cylinder head.  hence the question I ask is what would be best to achieve what he is asking me.  take pistons in 9.0 or 10.0 to avoid planing a famous 2mm on the block knowing that I worked on the dome of the cylinder head which became total hemispherical
    • 600km?! That's amazing lol, was that turbo or non turbo? I'd be lucky to get 400km on a tank lol (though that's mods for you i guess lol)
