I own an r32 gts-4 sedan and have recently blown my rb20. So now I want to put in an rb25det from an r33. Is this conversion straight forward? Will I have to buy front cut? Will this even work with my 4wd system? How much dosh would I have to fork out to get the engine etc. and get it installed? Thanks for ur help. :kick:

I've just recently done this. I used the RB25DET from a Stagea. This is the only alternative, other than a RB26DETT, because the R33 engine can't accept the the 4WD sump. I also chose to add a lightened flywheel, HD pressure plate and ceramic clutch plate, and run aftermarket ECU (Wolf 3D 4+). All up, I think it cost around $8k, but I did all the mechanical work myself.

If you get a half-cut - I think you can get one for around $4k - you get the loom and ECU as well. You will probably need a flywheel and clutch anyway, because manual versions are apparently as common as rocking horse shit.

But the results were worthwhile - ended up with nearly 180 kw at FOUR WHEELS - up from 115 awkw with the RB20DET.

Haven't had a chance to 1/4 mile it yet. But just driving it around, it's obvious that a considerable increase in mumbo has been installed under the right foot. eg, driving up Arthurs Seat hillclimb, crap ignition timing (idle = 40!!), RWD mode (temporarily lost the throttle signal to ATTESSA), minimal throttle, and little or no boost, it would light up the rear tyres coming out of the corners. Something only ever dreamed of with the RB20DET.

There is a HEAP more torque, and a lot more power.

    • Hey all  im wondering if you can help me please I have put a rb20 box in my r34 gtt as my auto packed up and a friend had a spare box I know it’s not ideal but it will get me up and running for now. we have done the conversation and everything is working great but my Speedo we got a s13 speed sensor but my Speedo reads double now and I bought a speed converter but still not having any luck.  so I thought I’ll reach out and pick your brains  any help would be appreciated please as I wanna drive my car again 
    • Drain it. I got official Matic D but you can get whatever is listed as Matic D compatible.
    • Thanks guys,  Yeah I should at least have them dynoed, at least then I know what I've got as a starting point.  The springs on these are hard as rocks. I vaguely remember Russman saying he was going to sell the shocks to me with the rocks fitted, as he was keeping the softer springs for his new setup.  I didn't click at the time but of course that was to let me know the shock/spring wouldn't be matched.  I also remember pricing up new springs around 2014-15, but, house, money etc. it never happened. So that was another reason to have them rebuilt. I have rebuilt the forks on many motorcycles so I think I could handle the seals on these easily enough, but getting the valving right would be a rabbit hole I cbf exploring.  Duncan, interesting to hear RP was tuning these back then. I might give them a call.  In the mean time I have been busy fitting sway bars. The Whiteline rear sway bar I purchased 15 years ago finally got fitted, along with the Whiteline front bar that showed up last week. Just waiting on new links for the front sway bar to finish that off.  And my spare set of advan AVS VS5's should be back from the powder coaters in a Pearl White finish sometime this week, with a set of Hankook RS4's lined up for fitting.  And then I just have all the suspension bushes to do. A comprehensive kit is on the way... Lots to do before the Ararat hill climb. Cheers guys 🍻   
    • Nice car! I’m glad folks in the US have gotten past the FnF and are buying real cool cars like the 260RS I was with a bunch of mates in Portland about a year ago and spotted a green Stagea (just a regular 2.5T AWD) parked about 2 blocks away and they were like “a what?” So I made a bet with them for a round of beers and said “ok one of you run down there and tell me if the steering wheel is on the correct side” 5 mins later the American comes trudging back up the hill and goes “he’s right guys. Ok what beer do you want?”
    • Should replace OR drop the tank, give it's good clean. Might be worth replacing that entire fuel level/pump/cradle thing with this: https://frenchysperformancegarage.com/products/fpg-s13-180sx-r32gtst-single-pump-hanger-kit-billet-hat-6-v3-fpg-089?gQT=2
