EFI_LC Posted February 24, 2011 Share Posted February 24, 2011 Hi guys, I just bought myself a NZ new BMW e34 5-speed and would like to know what mods are available that are straight forward also if there are any experts I can get advice from it would be cool.

spanners Posted February 24, 2011 Share Posted February 24, 2011 What does it go like? I have the same but 2.5 auto and its a sluggish whore. As far as upgrades go, the 4L v8 is supposedly very easy to bolt in, but i dont think you would need that as you would end up auto and slower. I have driven a few bms with exhaust upgrades and air filter etc, but it didnt really seem to unleash much power. Quote Link to comment Share on other sites More sharing options...
mikuni Posted February 24, 2011 Share Posted February 24, 2011 Sweet car man, bet thats a load of fun to burn around in. I have nothing else to add Quote Link to comment Share on other sites More sharing options...

mikuni Posted February 24, 2011 Share Posted February 24, 2011 535i M and 5 speed manual, a good combination. Quote Link to comment Share on other sites More sharing options...
rayban Posted February 24, 2011 Share Posted February 24, 2011 More importantly which engine does it have m20,m50,m60? Alpina b10 replica please Quote Link to comment Share on other sites More sharing options...
Raizer Posted February 24, 2011 Share Posted February 24, 2011 535i M and 5 speed manual, a good combination. Oh sweet, I'm too used to Gisborne where most BMWs have had M badges/stickers stuck on them LOL edit: shouldn't the M5 have the S38 3.6L or 3.8L engine?

CaMpylobacter Posted February 24, 2011 Share Posted February 24, 2011 it's not an m5. 3.5litre. so sweet. whack a medium case 4.1-ish ratio diff in it form an e30 auto. Quote Link to comment Share on other sites More sharing options...
EFI_LC Posted February 24, 2011 Author Share Posted February 24, 2011 Hi thanks.. Model is stock 535i motor but the car has M Tech add-ons apparently, excuse me as I am a BMW newb. Yer its pretty good for a heavy car. I don't wanna V8 as I have always been a keen inline 6 fan. I wound her up to 160km/h and thought I was only doin 120km/h The stats I got show its 3 seconds quicker to 60mph than the 2.5 motor with auto and has a top speed of 235km/h (146mph) I wonder what the Alpina motor has as it uses the same motor but has a healthy increase of power.

Sparkle Posted February 24, 2011 Share Posted February 24, 2011 no such thing as M extras reallly... Jus fellas pulling your legs. Although, it looks like a BMW NZ spec'd up 535i manual that was realised in e34s with all the options ticked. It prolly has a LSD? If no LSD, then as cam said, high ratio medium case diff would be your best bet, mine responded heeeaps to a free flowing zaust. Always wanted to chuck a link on mine and biff the factory afm, but never got round to it/had the $ to. The other thing I wanted was someone to build a mean set of headers. These have fairly yuck log manifolds. Basically anything that's not 3 series will bolt on brakes wise if you want bigger, E32 7 series, E31? 8 series etc. But probably no real need. M30 ftw though. Sweet engine. Quote Link to comment Share on other sites More sharing options...

Sweet engine. Sweet now thats the info... I should go find an exhaust gasket and buy some bends and see what I can come up with What are diffs worth? Maybe a microtech Yea its got extras but i dunno if they were normal or not like the auto adjusting mirrors linked to the electric 3 memory seats and mirrors that auto change when i select reverse, speakers and lights everywhere lol. i must read the manual. i should jack her ass up and check for lsd Quote Link to comment Share on other sites More sharing options...
CaMpylobacter Posted February 24, 2011 Share Posted February 24, 2011 numbes on tag on diff head will give you ratio. i think if it's got an 's' in there it's lsd. jacking it will tell you anyway. diffs are cheapish. sparkle's e28 had a 3.05 or some shit whihc gave about 12903482385492384238042kph in 3rd gear. tall diff ratio really held back it's potential. if you're boss as and it only does like 1200rpm in top at 110k like his did, get another diff, try it out, and if you like it, slam the lsd centre (assuming yours has one) in it. a 3.73 is the apparent ideal for these, though. sparkle's with a 4.1 would have been super rapid, i reckon. keep it off the rev limiter (apparently these smash rockers at like 6800 or somethign and they limit at 6500... something like that, although rxsumo's e12 m535 had a fucke dmechanical limiter and that's still rockin) they get asthmatic over 5.5k anyway also, exhaust as sparkle said will free up a few neddys. also, pay careful attention to the cooling system. headgaskets/head are fairly fragile in these. e34 535 is one car i want to own at some point. so soooo sweet.

EFI_LC Posted February 25, 2011 Author Share Posted February 25, 2011 Cheers mate... This actually has had broken rockers previously and had the head rebuilt and bores etc checked with nothing else needed so hopefully it will last a while longer Interested in your comment about asthmatic past 5500 as it says peak is 5700 with 155kW I drove a few and wasn't impressed with them until I drove this and being a 5-speed I thought perfect, the fact it was NZ new and had a service history even better. 2 things though you may be able to help with, the brakes are ABS but feel a bit spongy and the clutch feels heavy is there anything worng or is this normal? This will never match my Torana in acceleration but has a feel of smooth, power and long legs. Quote Link to comment Share on other sites More sharing options...
CaMpylobacter Posted February 25, 2011 Share Posted February 25, 2011 lots of euros have spongy ABS brakes. often half of it is just because ABS brakes are spongey. the other half is becasue often they'r designed to be 'left hook' and instead of moving everything to the right for RHD markets, they have an array of linkages from the booster on the left, to the pedal on the right.

spanners Posted February 25, 2011 Share Posted February 25, 2011 Just in comparison mine has no abs but brakes are legit as. Does yours possibly need a bleed? Quote Link to comment Share on other sites More sharing options...
EFI_LC Posted February 25, 2011 Author Share Posted February 25, 2011 The engine number is interesting.. BF00004 they couldn't have sold many before it? The brakes work well but and they pull up well but compared to what I thought they would feel like its slighly spongy. I know what ya's are talkin about with the tall gearing but the torque takes care of it nicely. I might enter it in the flying 1/4 this year Quote Link to comment Share on other sites More sharing options...
Testament Posted February 26, 2011 Share Posted February 26, 2011 Yeah I always quite liked these since the old bathurst days - I think denny hulme passed away in an E34 M5? I can think of worse chariots to cross the line in. From what I recall the 3.5L motors are quite low compression, hence the not so spectacular power output. But it means they can probably take 5-7psi of boost which would make several worlds of difference. Quote Link to comment Share on other sites More sharing options...
bubblegoose Posted February 26, 2011 Share Posted February 26, 2011 M extras list: colour coded sills different bumpers different door moulds also if you give bmw your vin they can tell you what the optional upgrades were when it was made/ordered Quote Link to comment Share on other sites More sharing options...
isnowi Posted February 26, 2011 Share Posted February 26, 2011 M extras list:colour coded sills different bumpers different door moulds also if you give bmw your vin they can tell you what the optional upgrades were when it was made/ordered It's also highly likely the build sheet is stuck to the inside of a panel somewhere, sometimes under the back seat squab and the floor of the boot are two common spots, it will all be 3 letter codes which you can look up online. These ones will only tell you the factory fitted extras, there could also be NZ dealer fitted extras. Quote Link to comment Share on other sites More sharing options...
