So unfortunately I recently had to say goodbye to my R34 gtt after itcleaned up 3 trees and lost the battle. It was a 4 door with the gtr front end conversion, with the standard engine making just over 300 rwk. I have since bought a new R34 gt auto and was about to transfer all of my engine/manual conversion/ etc etc etc over into the new shell along with a new gtr front end to replicate my old car, only better.

I was just speaking to a friend and he offered me his r32 gtr motor with power fc , loom and gearbox for a fairly nice price, and Im in two minds of what I want to do regarding the new 34. Im very tempted with the gtr motor as I know it has legit low kms and I know its history etc, but not so sure on how big a job it will be to install in to my r34. For instance Im assuming the wiring harness to ecu for dash looms etc will not work with tht r32 gtr power fc, i wil need to change the sump to convert from awd,and will my gearbox bolt straight up? will it be a lot of work and a headf**k to get the engine through regency, as i dont want to do it dodgy... will i hve to upgrade to r34 gtr brakes etc etc etc..... So basically I am after peoples advice and thoughts and experience on the matter and if someone knows what is involved etc

My rb25 neo i was going to put in was making 304 rwk fresh motor, low kms, upgraded injectors, turbo, coilpks,z32afm, fmic fuel pump etc etc,, so was also a very reliabel setup and with a reliable and safe tune, so i maybe be better off sticking with this...but the thought of a r34 4 door gtr with rb26 is also very tempting.....

if anyone has advice and thoughts on this id be very interested to know whats involved and risks/problems, etc......

thanks for ur help in advance,

......and on a side note if anyone needs r34 4 door parts il soon be stripping my wreck so pm if u need anything......

Eli, what you're contemplating is a hell of a lot of work, that will see you off the road for a very long time, that will not get you through Regency, and if none of that phases you and you still go ahead with it, the final product will still be a 34gtt that's worth buggar all

Regency doesn't have a list of what engine numbers correspond to what year, so you could possibly get away with it, as all RB26's have the same engine prefix followed by a unit number. Send in an application to modify, and they will tell you exactly what has to be done, and if it can be done, just write TBA where it says engine number, because that way they won't put anything to the rego of the car. So if you don't do it, it's no drama's.

There's a bit of a loop hole I found in the system to do with engine conversions when I did mine, but that's on a need to know basis :P

They'll still sight the number on the day and then cross reference, and by number it'll probably highlight to be from a 32

The bigger problem here is whether its an early/late R32 RB26 (ie does it have the long nose crank or not), otherwise you might be in for a nasty surprise if its an early one and it decides to let go

As you'd have to find a sump etc to convert to RWD, its prob easier to chuck in your turbo Neo motor and be done with it by the sounds

Sorry to hear about the car mate :(

What sort of condition are the plastics in on your old 4 door? The plastic surrounds on my front driverside and passenger side are sun faded so would like to freshen them up with a pair in really good condition.

Matty I'm pretty sure they dont cross reference, people run into dramas when they take an obviously older engine through (eg RB30 in a R32 onwards). Either way, I'm yet to meet a person who has personally been in the situation of not being able to register an older same-series motor.

But yeah stick with the 25 I reckon, purely for reliability.

RB26's are like s1uts, everyone loves them, and they're a fun ride, but there's usually nasty things that lay beneath the surface.

Thanks for the feedback- this is what i wanted to hear. Was swinging towards keepin the 25 and perhaps going further on that engine. Just wanted to see what peoples thoughts were on the matter and especially regarding the legalities... Read an article on a Perth mob who had an awd 4door 34 in perth ad they did the rb26 conversion along with gtr panels etc etc, kinda got me thinking along the same lines...minus the awd part... Hahaha at dions last comment...

Pete is right it will be a hel of a job and drag out for ages, I'm not looking forward to swapping my current gear as it is... Big CBF factor right now :(

Brett when u say plastics can u be more specific- I have no idea what u r refering to- shoot me a pm.

    • So, I started this repair and got as far as "fixing" the holes with some fibreglass. God all those years working on boats came back quickly. I decided I'd reach out to some rust guys just to see what they would say about it. I came across a guy about 40 mins away and went to see him. He said the windscreen needs to come out, that there might be some more bits around the windscreen and he'd quote them at the time. But his quote was $300 to remove and replace windscreen and $3k for the damage he can see. He said he could respray the roof for $1200 and the bonnet for another $800 (somebody has previously rattle canned it, its horrendous). This is $5300 + any small additional bits. It's a lot, I get that and the name of one of my fave youtube channels 'Not Economically Viable' comes to mind.  I'm not being financially rational, but I've taken him up on the quote. He's opening a new shop in November with more room, so we're waiting for that. I'll leave the currently missing headliner out until then. I'm looking forward to it being fixed and having the paint looking nice again (lots of clear coat issues on the roof too). / flame suit on.
    • Oh and some up-and-comings; New rear drivers wheel bearing. I'll do that this weekend while the diff is out. The car is already up and the d/c axles and missing exhaust will help with space. This is the last bearing for me to do and I've been dragging my feet on it. I also have some new EBC blue stuff pads for the car and some new brake fluid. I haven't ever flushed the fluid in this car and looking forward to it. I have 600 degree fluid to put in. Not exactly "race fluid" but better than the typical stuff I have been using.
    • A proper clutch/plate type mechanical diff with quite a lot of pre-load and high locking % is better for drifting. Much more consistent in its behaviour. A helical can be annoyingly vague and inconsistent in how it responds under the sorts of abuse found in drifting.
    • Some updates here. I pulled the entire interior out, minus some trim to respray the seats with Colourlock dye. It turned out really nice though I accidentally let the dog in the car after and she scratched up the front seat.  This is what it looked like before, the colour was just washing out everywhere but thankfully the leather was in good nic. Then after the respray   And after the bloody dog jumped in The headliner is out waiting to be retrimmed, but it will stay out now until Nov - see why below. I replaced the stereo/headunit with a period-styled Android headunit. I have no after pics, but I'll get some. This is because of the missing pixels. I tried to fix this twice with replacement ribbon cables but couldn't. Also the bluetooth interface I'd bought for this was crap. Then there's the rusty roof. Pics and info in this other thread. I have decided to get this repaired professionally, but I'll update that thread. This is why the headliner will stay out for now. I'll be getting the roof and bonnet resprayed at the same time the rust is fixed. I also had an interesting issue with my drivers door lock.  For a small period I was having issues getting any 12v power to the car - I mean *any*. It would have no dash lights, nothing. It happened while I was at the shops and I couldn't get in the car. So, we had 2 problems. The most pressing here is that I was locked out. I have only a single physical key hole on the car, the drivers door and no amount of turning would unlock the car. Surely it doesn't need power for this? The second issue is why am I losing all power periodically, The battery isn't dead, its almost like the battery isn't even there. Two issues that were surprisingly easy to fix. You fellow BMW over-engineering lovers will appreciate this. The lock in the door has 5 states; mechanical lock, electric lock, neutral, electric unlock, mechanical unlock achieved at -90 degrees, -45 degrees, 0 degrees, 45 degrees and 90 degrees. Although, the unlock is towards the front of the car, so opposite for LHD countries. Sticking the key in and turning 45 left or right is what is used 99% of the time. It activates the central locking etc. 90 degrees is for dead battery access and, obvs, only un/locks the one door. But because the mechanical lock is never used and is 27 years old, it seizes up. I was totally unable to turn the key far enough to get to the mechanical unlock (At the time of locking myself out, I didn't even know this was a thing). I eventually did it with some vicegrips and teflon spray.  I made a quick vid for other E39 peeps.   The battery issue is totally new to me also - It wasn't making sufficient contact between the post and the terminal. The terminal was bolted on tight, but the car wouldn't have power. After checking the battery with my multimeter I accidentally contacted the terminal and the battery post and the car got power. The battery was only a few years old and in good condition. I cleaned the post and the terminal with a wire brush, bolted it back on tight and never had the issue again. I'm still surprised that despite having solid contact it didn't work. Also, the car was getting Warragamba sized pools of water in the back when it rained. My initial concern was another rust problem. But when I went out on Weds while it was raining and while I had no headliner in I could see a steady stream of water coming through the roof mounted aerial. As this aerial is for the (now removed) car phone I pulled it out and whacked a blanking grommet in the hole. It seems fine now. I'm thinking I might get the hole permanently filled when the rust is fixed. Moving forward and things in progress; The tailgate needs some attention. I have taken all the trim off to clean it all and address some small rust spots. I have partially done all of this but I'll finish it up hopefully this weekend. As all the trim are now entirely devoid of trim clips I have bought a heap of strong velcro and I'm hoping it does a good enough job as any of this trim in good condition is super expensive and usually in Europe as we dont have many of the wagons here. Suspension and brakes!!! This is exciting. In the front; New control arms New sway bar links New lower Eibach springs (the only modification I'm planning on this car) M Sport shocks (these came with the car and will replace the longer shocks in the car) New top mounts Used 540i calipers (stock brakes suck!) New 540i disks and pads (22x296 mm for 528 and 30x334 mm for 540i) New front wheel bearings (thank all that is holy for bolt on bearings!) Annnnd in the back; New control arms New sway bar links Adjustable air suspension arms (fool the car into what the current height is so the self levelling suspension can match the new front ride height) New ball joints I'll also be doing a brake fluid flush while I'm in there. I'm planning on switching the car over to the 16's that came with it so I can clean up and respray the M Sport 17's. They've lost a lot of colour over the years and have some gutter rash. None of this will start until the E90 is back.
