nz320i 0 Report post Posted October 27, 2005 (edited) Its now manual, with a 4.1 diff, lol. kinda funny with 4.1 saving for a newy now prob a 3.63 i suppose. Heres the full costs: Box $500 (Trade me) :mosh: Pedal box $120 Flywheel $100 Clutch kit $120 - mint deal so if you are converting you'd need $350ish.. Shifter linkage etc $60 New resiviour and piping $50 (OEM from dealership) New master cylinder $95 (BNT) Driveshaft Lengthened $165 (circle track engineering chch) Slave cylinder $50 All parts were from a wreckers and were really good bits, the clutch was 2nd hand but had almost no use, the flywheel was still shiny and the clutch almost untouched. Total cost was $1400 Cant remember all the bits cos im to lazy to get the docket out of the car so ask me if you want to know, thought this may be helpfull as i wanted as much info on prices when i started doing it. Cheers! Autos are bad. Edited October 27, 2005 by nz320i Quote Share this post Link to post Share on other sites
petone 0 Report post Posted October 27, 2005 Done your first burnout yet? (Controlled cirumstances of course) If your box is in pretty good nick get yourself a short shifter. Also what did model did your box come out of? 320, 325? I think a 3.63 might be a bit low for 320i. My mates 320i was a 3.91 factory. Talk to carl, hes been through a few diffs.

nz320i 0 Report post Posted October 27, 2005 i was quite lucky it came out of the same year and model 320i, might go for a 3.91 then, you can take off the 2nd! Quote Share this post Link to post Share on other sites
bravo 35 Report post Posted October 27, 2005 My box came off a 320i sport (SA), and so is slightly closer anyway for that extra go off the mark - NEEED a new diff and thinking 3.73 or 3.91. My total was $1800 and I used fully new clutch (but not master and slave) had to buy some tools and did the short shift conv, so pretty much apples for apples. Congrats on getting it finished Cameron - how's my shifter doing? lol You forgot that in your costing - a steal at $35 incl. postage hah! Quote Share this post Link to post Share on other sites
petone 0 Report post Posted October 27, 2005 Can someone tell me whether it would be worth me swapping to a 4.10? I have a 3.91 atm. I've had a look at Carl's spreadsheet but I don't know how much extra pick up i'd get. I can think of someone who might want to swap diffs... (assuming they are they same case size) Quote Share this post Link to post Share on other sites
DCEIVN 0 Report post Posted October 27, 2005 Yeah cam Im running S3.07 too as mine is the same from when it was converted from auto. I'm probably going to look at 3.46 though. I heard from somewhere that it's a good idea to stay within two stages of your current diff - anyone agree? I also looked around and read that 3.64 is probably the best all round for teh e28 manual. Dont know though - Ebay is selling a couple of S3.25 diffs at the mo though. Quote Share this post Link to post Share on other sites
bmwsparkle 3 Report post Posted October 27, 2005 u can always chuck a different crown wheel and pinion into ur slippy and make it a different ratio, thats what i may do. im gona go for a 3.46 i think, probably because its sitting in my shed at the mo Quote Share this post Link to post Share on other sites
DCEIVN 0 Report post Posted October 27, 2005 is that quite hard? I wouldnt mind two diffs reason being is I can change it depending on the track. the 3.07 would be much better for Puke than it is at fielding. Quote Share this post Link to post Share on other sites

RageX^NZ 0 Report post Posted October 31, 2005 Hey, did you change the fluid in the box, and if you did how did you get the plug out? Quote Share this post Link to post Share on other sites
Carl 3 Report post Posted October 31, 2005 Hey, did you change the fluid in the box, and if you did how did you get the plug out? You need either an extremely large allen key or use the poor man's method and find a large bolt that'll fit into the plug then use a pipe wrench on the bolt to undo the nut, works quite well.

Coffee&Doughnut 0 Report post Posted October 31, 2005 I will beguin looking for parts for a manual conversion soon, I didnt really want to have to buy a diff as well but its probally inevitable. I dont fully understand what the effects of keeping the 4.27 would be. Would it be a total bitch? Quote Share this post Link to post Share on other sites
nz320i 0 Report post Posted October 31, 2005 Hey, did you change the fluid in the box, and if you did how did you get the plug out? yes used castrol VMX, and lol the plug was a mission until the guy helping me (wrecker/mechanic) made up a bolt that fitted the allen key hole with a massive lever on it, welder, and got it open that way, otherwise allen keys arent too expensive Quote Share this post Link to post Share on other sites

Would it be a total bitch? lol 4.27, well it would be nippy off the line but youd be chopping through gears like me i imagine, mines a 4.1 and at 100km/h im doing 3500rpm which in my opinion is too high for a car that has that much tourqe??anyone agree?

Coffee&Doughnut 0 Report post Posted October 31, 2005 Currently on a flat piece of road its about 2500 so 3500 rpm is a bit too much agreed, How much dose a manual gear box wiegh approx? Would it be ok in the boot of an e30? Quote Share this post Link to post Share on other sites
