hi

just have some technical questions concerning doing the auto to manual conversion and who has done it before?

RB25DET 5 speed from a coupe into a auto 4 door.

I wish to retain the standard (well sort of standard in my case) auto computer.

things that concern me are the speed sensor?

tailshaft for a 4-door - same as a 2 door? or will the auto 2 peice be similar to a manual 4 door?

and anything else i should know concerning wiring etc.

thanks

Matty

Dont do it man!

Why u no likey auto? its faster than manual just not as controllable, less top speed and slower launching.

spend the money buying a 25xx turbo etc coupled with perfect gear changes all the way to redline and no loss of boost between shifts.

Then again, if you wanna drift get the conversion, auto drift is unpredictable compared to manual

Tailshaft is different length I think...

You can get away with Auto ECU but it won't be optimum as it would be cutting power at shift points at certain rpm (still thinking it's auto). May be running a leaner fuel map than manual ECU, SAFC is recommended to fix this. If it's not included in the conversion package, try to get the Auto ECU replaced with manual one at a later stage.

Speed sensor shouldn't be a drama. The worst you get is due to auto/manual diff ratio differences (4.3 & 4.1) , you'd be off merely 4% in speed.

      Noted. Have noticed BMW are more 'high maintenance' for sure. They've attracted my attention as I think the used car prices seem reasonable vs other options, and the extra quality overall vs a commodore / camry / corolla or similar of the same vintage is appealing, especially the interior, and they are more on the sporty side whereas the others mentioned can be more cruising or economical A-to-B only.

      Haha yeah I know, this is SAU after all, why are we talking about BMW's of all things!? I hear you on the 'don't have to worry about it' side of things. Having been fortunate enough to be have been able to buy a brand new motorbike or two...never really enjoyed them as much as I'd have liked as you worry so much about where you park it, will it get scratched, stolen, attempted theft, knocked over, etc...and yes dirty. Older less valuable bikes you can just go where you want and park it wherever and not really worry that much in comparison. And who cares if it gets dirty! Never owned a V8, and have had my eyes on VE / VF commodores for years but with their prices climbing so high, the M3 has come into focus more as prices are much closer than I've ever seen...is it a potential contender now?...of course need to factor in the S65 'maintenance' especially and like you said general M car 'tax'. One can dream anyway. But more on the reality front - did read the whole 330i thread as well and was a great read too, both threads enlightening as I've never even driven one of these cars! I do recall 330i didn't seem to have the same amount of issues for almost the same car (turbos and related differences notwithstanding)...perhaps down to getting it earlier in it's life so looked after better than the 335i? Perhaps so as your 130i has been good and quite similar, so finding a car that's been looked after well is the especially-crucial-BMW-first-step.

      Nice. Dont worry about the time of not running. My current skyline hasn't run since I bought it. About 8 years ago.

      It's also worth noting that I am heavily and unconditionally biased. I've had a lot of cars including some GTRs a fair while ago. I love my BMW's now a lot. They make no sense a lot of the time and the guys on here remind me regularly that I could get something else that does what I want better and cheaper. If you're going to take on an older BMW it's definitely a commitment. If you bail on it early you'll lose money and also the ability for it to put a smile on your face. Stick with it and it just gets better.  f**k I should get into advertising.

      Careful with posts like that around here without the flame suit on @cobo_11! 😂😂 My 330i journal is on here too. That car was so good and super reliable. We still have a 130i in the family which is almost identical to the 330i and easier to find in manual. It has also been almost faultless over the 6 or so years in the family.  I used to want an M car a lot more than I do now but if I'm honest and without trying to sound like a wanker, I can get such good performance and handling out of my 335 without needing to worry about all the crap that goes along with M car ownership. I don't need to worry about my bearings or subframe issues or the cost of replacing brakes or suspension or whether it has been impeccably maintained. And I can leave it places and not get upset when it's always filthy.
