For sure man. A lot more torque and off-boost power, quicker spool up. Only thing I miss about the 20det is the sound.

Not mechanically minded, are ya?

So, amazingly, I've had 0 drama's with the 25 since we put it in. The TPS and idle is a little off, but that's it. I put my SuperSpark coilpacks on, and silicon induction pipe (needed to be trimmed down a bit) both off the 20DET. Did some cosmetics today. Been some delays with my stuff from Japan, but in about 3 weeks, my OEM front lip spoiler, and intact right side tail light will be here.

Both bottles = R32

The 30e uses different plugs for things like AFM, CAS, injectors, etc. But you could just take all them off the 20 and use the 20 loom on the 30

Check the big fuses near the battery in the engine bay, and the negative leads off the battery

Kris trolls these forums hard...well he doesn't troll, but he does post here. Im sure he'll spill the beans. I put mine underneath the battery tray, outside the engine bay

More info mate. Any lights on the dash? Is the fuel pump priming? Accessories, lights etc still working?

I did 25DET swap last week but thanks for the walkthrough I still say better off with a 26DETT.

Id actually pay to see all these guys who swear by the rb25 to actually install one themselves.

If it falls through with Richard let me know. I've got some blanking plates somewhere. The manual and auto foot rests are different, the auto ones are wider by about 2 inches, but the good news is they're interchangeable from R32 (definately) and S13 (not 100% sure) Otherwise, it's pretty easy to cut down an auto footrest.

Got stuck in this morning around 10, and after several hours of f**king around, got her back on the road around 9 tonight. It really does shine that it only has 68000kms on the clock. Runs flawlessly. It'd been raining all arvo here in Perth, so the test drive was ah...interesting. Between the low-down power, lightened flywheel, and going from 1 inch of slack in throttle cable, to tight-as-f**k throttle cable, it got a bit tail happy more than once, without me even trying (in some cases, actually trying to avoid break-traction) Once it's all tidied up, I'll start chucking my goodies from the 20DET on there, like coilpacks, solid intake pipe, etc.

Rear bar resprayed shortly after the front was done. I wasnt too thrilled about how some area's turned out, so I ordered another bar from Sleeka Spares, but then lost motivation to paint that one. The 20DET started giving me hassles again last week, and finally threw in the towel. Intermittently running on 5 cylinders, then 4, then couldnt even get it to idle on all 6, and it'd cut out completely under load then the big end would make some noises I didn't like. Turbo had produced 1-2mm of shaft play, even more when it's warm. I towed it home last Monday, then towed it again to my mates place this weekend, and ripped the 20DET out. End of November, I was working some hardcore bullshit hours (10-14 hour days, 12 hour saturday, 10 hour sunday, repeat), and racked up "a little extra coin", so I bought a 25DET outright. I never really had a plan about what I was going to do with it, I just bought it, and figured it'd end up in something...one day. It sat at my mates place for over a month, and now it payed off. She's an S1 with 68xxx kms. I spent a good $590 ++ at Nissan on gaskets, nut, bolts, etc for the top end. Well worth it. Engine bay got a quick degrease tonight, but still filthy.... Motor and box ready to rock'n'roll ...aaaand, IN! Picking up the wiring loom tomorrow night, so hopefully she's back on the road Wednesday/Thursday, after my quickest ever motor swap.

None. From the centre bearing to the yoke, it's the same as R32. The longer half is specific to A31/C33, From memory they're 40mm? longer than R32.

Thumbs up exchanged with 4-Door R33 on Kwinana Fwy (Northbound) this afternoon.

^ That's awesome! Don't change a thing

Would be better off getting an RB25DE out of an R33, with it's loom and ECU. That'd go straight in, without needing to modify the harness. You certainly don't want a 20DET, and yes, your existing gearbox will bolt straight up.

Yea they came with 20e

Neg mate not anymore.

Yes definately works

Noobs, a32 and a33 are both too long for a31. A31 shields are on eBay international, in Thailand or some shit.

Looks like you've rushed trying to get that engine bay back together and motor running.....

Yeah they're still here. Actually going to take them this time ?

Yes it will.

Yes but gtr diff has different tailshaft flange, 6x1 bolt driveshafts which only suit the bigger gtr hubs. Use gtr centre, flanges, shafts and hubs. Existing diff housing and tailshaft.
