  1. I'm using 42p offset on some 17 x 7's. Fitted fine with standard lugs. But put some 10mm spacers in there to beef the appearence up and widen the track a bit. Needed longer lug studs though. Looks mean and I got a warrent with them in. Haha the old fella didn't even notice.. Amazing what a coat of paint does


  2. Hey Mate a little knowledge [in the wrong hands is dangerous]sorry about that.

    A responded to your question about compatability of engines & boxes [but added extra info about 'gearbox ratios & diff ratios'] these I got from a USTCC homoligation form for E36 325/328/M3's

    The answer to all your questions is YES [Just bolt it all in] What I was trying to point out is BMW ZF S5-16 boxes with their respective diffs were just as compatible as the 1:1 5th Boxes with their diffs

    Everytime I hear of people doing a Manual conversion,they go running around looking for a manual diff [You don't need to with this box]

    Look at the bright side,At least I got one person to pick-up their calculator [Enough to make my maths teacher proud]

    Yeah sweet man

    Was useful information

    Gets me thinking about what sort of ratios to go for


  3. How the Fark did we get onto the subject of diffs last time I asked this question...

    I have a south african built 89 320i shitter with a ZF S5-16 5spd Manual standard. Will this transmission work with my 92 m50 2.5ltr? Bare in mind I will plan on using my m20 flywheel and starter 325i standard clutch "new". Will I have any angle problems? I allways read about getrags and there isn't much round about the ZF S5-16. Plus all that I find is all in german. Any advice would help,

    THanks


  4. Why would you need a custom rear mount? Both the M50 & M20 are on the same angle [it looks different on the M50 because of the 24valve head] In fact the crank can be swapped over in stroker situations [check out Bimmersport forums HaHa!!] I have physically swapped over a gearbox from a M20 to a M50 they do bolt up. Use the M20 flywheel It's lighter [they are all internally balanced]that way you can also get rid of the bullshit dual-mass M50 flywheel [unless smoothness & driving like a Nana is your cup of tea]

    Just a note to others reading this [because I've asked this Question myself and got "Don't know" as a reply]I took my M50 backing plate & bolted it up to a M40 engine [the M10 is different]

    The Ratios in the S5-16 are 1st: 3.50, 2nd: 2.01, 3rd: 1.34, 4th: 1.00, 5th: 0.82

    usually with a 3.86 diff [uS spec]

    The Ratios in the E36 M3 [and the 325/328] ZF box are 1st: 4.210, 2nd: 2.49, 3rd: 1.66, 4th: 1.24, 5th: 1.00 usually with a 3.15 diff [uS spec]

    If you do your maths and multiplied the gear ratio's by the diff ratio's you would find the overall ratio's almost identical [by using the S5-16 box in a manual conversion, you should still be able to use the auto diff]

    :lol:

    Bad!Cheers for the info.

    Sounds like I just need to get into this swap and cross bridges as i come to them.


  5. Just climbed under my 1989 320i 5spd to check my type of gearbox I have in preparation for swap this m50b25 in and I see it's a ZF S5-16 not the getrag 240 that I keep reading about. WIll this transmission housing still work with my m50 ? I'm planning on using my m20 fllywheel and starter and new 325i clutch kit. I would have thought if it's bolted to my m20b20 then it would bolt up to my m50b25 (and yes I will be making a custom rear mount to sort the angle of the gearbox out).

    Thanks

  6. Ahemmm!....... S50 thank you very much! The M50 swap is so well documented on sites such as R3V it is almost pointless going through the whole scenario here. Have a look here:

    Yeah man that's a great forum I have made a haines manuel type book to help me with my swap. Was just looking for sum local knowledge. You know what americans can be like.... There are alot of cool e30s around the net. I went for the cheap m50 as I have basically no budget but a 320i with a tired motor.

  7. Has any body in this fine country of ours done a m50 swap before.

    I have a 89 320i south africa new 5spd and have aquired a 92 non vanos 2.5ltr which I''m going to attempt putting it in the next couple of mouths. I have done lot's of reaserch on this swap allready and just about have all the parts I need (just saving up for clutch etc) and realise there is heaps of information located around the net but was just wondering if anybody down here in New Zealand have done it??? ps I bought a non vanos motor as I'm looking into forced induction once it's in and running and have ironed out some problems that may arise.

    Thanks

  8. Did you guys know that connected down behind the brake pedal is aye big rod that goes from the brake pedal behind the firewall to the master cylinder is adjustable. Need 2 17mm ring spaners (note. this is f**ken done up tight!) Adjust accordingly. I had re honed and kitted my master cylinder, new rotors all round, metal king pads, new dot 4 fluid but pedal feel was still sh*t. Adjusted this rod prestow. Note. Don't over adjust as this will push the master cylinder rod right in and brakes will be stuck on.


  9. Yeah man mines doin the same. Change the fuel pump, press reg, had it pressure tested was all sweet. After long and frustrating nights trying to find the problem I thought about changing the fuel pump relay and boom. The fuel pump was now priming on the first turn of the key not just when turning over. Hope this helps. New to the Bmw's. Have being a Commodore man but got an e30 done the brakes and suspension and i'm hookd. Well engineered car!
