335i project pics

[alan335i]

Finally got around to starting my 3.5 conversion in my sport,the 2.5 had a misfire and after throwing a pile of money away on new parts and taking it to a good e30 mechanic the problem could no be found so i stripped the head of the car but still found nothing so it left it being an electrical or injection fault,rather than wasting more money on parts i decided to go for the 335i .i've had the donor car for three weeks but only getting around to starting now, might need a few pointers along the way,heres a few pics to keep you posted on my progress

[Andy335Touring]

Nice to have a garage to work in !

Keep the pics comming

[DRIFTBOY]

I'd love a workshop like that too - aaah, the luxury!

Looking forward to seeing more pics of the progress!

workshop jealousy here too!!! i do have a garage now but the E30 won't fit in!!! i also have a drive now but when poarked up against the door, the car sticks off the end by 6"! the only thing i can do now is use the garagedrive (open the garage door and park it partway in!!!!) still, it beats nearly getting hit by every passing car when working in the road!!!

your donor car / engine looks clean which is (hopefully) a sign that it's been looked after

got around to removed the m30 today,little problem,the engine loom runs along the injection rail and the straight into the main loom runing along the bulkhead,do you have to cut this loom here ,wheres the round plug on the e34.do you have to use the ecu out of the e34?sorry if this has been covered but i'm not much good with the wiring side of things.

[Toby_Unna]

the round plug is the right hand one in the third pic down - next to the diagnostic plug with lid - bottom right corner of pic. it sort of unscrews...

m30 ecu needed. the whole engine loom ecu etc should come out as one, and just needs earths etc and the round plug connecting

looking good anyway

I did the same. finally ended up in 335 swap. now doing few more tweeks on the M30....and still.. at GETTING READY state.

[325ispart]

gettin on well i c whos the hard worker? give me a shout wen you finished wit the 5 and i will take it off your hands for free !!

[SPADGE]

Looking good
Is that Twiggy's e34?
Cut that square grommet off the engine loom and replace it with the round one off your 325 loom.
Use the ecu etc that came with the M30.
Don't cut any wires there is no need just disconnect them!

[SPADGE]

Where are you based by the way?

[alan335i]

i bought the e34 off a bloke in shrewsbury,can't remember his name,it was on ebay,i'm from northern ireland,not a big lot off 535i s over here,got a new head gasket fitted(slight water leak),painted the rocker cover and manifold as well as a coat of paint on the block (pics coming) ready to go in to the e30 this week.wouldn't mind a trip over to a e30 meet over there when i get it finished, any big ones around june?

[e30Alex]

Hey, what engine mounts are you using?Alex

[alan335i]

making my own mounts alex,got the plates made yeserday at a local engineers,don't think it should be to much trouble getting it lined up,going for around position 3.the steel was only £15

[ed325i]

the steel was only £15

Thats how much mine cost, its a lot cheaper than buying them ready made.

[alan335i]

got the wiring sorted out,the engine loom was taped to the main loon ,i took the tape all off and the loom came away as one,i should have looked a bit closer in the first place,one problem but the two multiplugs are different sizes,when changing the plugs over is the wires the same colour?think i seen somthing about this on here b4.

[brian325i]

mint looking..
is there trouble with manifolds for the 335 conversion? you gonna declare it a 335 on tax book..i not sure if to change book to 2.5 or not.. i think i will as it be safer but 24v 325 dont exist so i could say it a 12v..but how you gonna explain a 3.5 litre

[alan335i]

putting the m30 in later today,might have time to start making an exhaust up,got the new tubing and all,i'll be running a de cat system,will this run ok or will i need a remap,do i need to refit the oxygen sensor back into the system?

[e30Alex]

Aparantly not, so im told, but i also have the same problem and im dubious!Alex

[DRIFTBOY]

It is actually illegal to change engine capacity and not inform the DVLA!

I have because I'm a responsible, law abiding pillar of society!

I don't think there's any difference taxing a 2.5 or 3.5, is there ?

That manifold and cam cover look alan335i ! Nice!

Martin.

[alan335i]

i thought you had to get a inspection done on a car when you put in a different engine if you were going to change it on the log book?

[Andy335Touring]

all you need to do is fill in the CC's and the new engine serial number

[alan335i]

quick update,got the engine in and positioned yesterday ,measured up and made the mounts,its clearing both the exhaust flange and the servo and i'll be able to use the e34 rad ,i was able to use my original gearbox mounts,the prop shaft looked around the right length ,just to try it i took the flange off my 325i sport box and fitted it to the m30 and the shaft went straight onto it,has any one else tried this?looking at it i can't see why it wouldn't work.it would save a bit of hassle if it would.

[e30Alex]

thats quality alan, ive just done the same, in the process of making my mounts, i just need new rubbers first. TBH i had the same idea about the prop flanges, havnt actually tried it yet tho. Get some photos up mate!I wana see the beast!Alex

[alan335i]

have almost everything conected back up again,just a few small things to do now,throttle cable,rewire the multiplug ect. ,think i'm going to try the propshaft the way it is to see , i used a 530d front mounted fan ,it fits nicely with only few mods,heres some pics of what i got done this week.

[DRIFTBOY]

Looking good dude!

Won't be long now!

Agreed!

My swap has slowed right down now that I'm rebuilding the engine (reminds me I should put up some pickies).

This could be a stupid question but the sump looks super close to the subframe and steering rack in that pic above. I'd have thought there'd be some vertical movement (ie, say high speed over a crest?) that might be cause some damage to the sump?

there is clearance between the two,if it settles down on the mountig
ngs i can shim it up a few mm,not be a problem

[dimebag_from_hell]

Looks good lad, where abouts you from?

[alan335i]

Looks good lad, where abouts you from?

from coleraine,what about you ? see you're interested in the m30 conversion,if you're in the area you could get a look at mine. Got the wiring sorted at the weekend ,got her fired up for the first time this evening ,can't wait to get the thing on the road now,just the clutch cylinder and the exhaust to sort now,aquired a e36 m3 evo back box at the weekend,think that should do her.

[alan335i]

after having a hell of a time tring to bleed the cooling system i've finally got it finished,(well just the mot to sort now)not as easy over here to get its about a month waiting list at the minute.had it out on a trial run in the wet today,bit of difference in power from the 325i,getting wheel spin in 4th at times.think bigger brakes is called for,any options to use?my lsd isn't pleasing me its unlocking quite a bit,would a good oil change help any?i here miller oils lsd oil is about the best,or is it a case of a diff rebuild or a replacement.i get a few new pics up when i get a chance.

[Andy335Touring]

Cool, what was stopping it bleed in the end ?

This is the stuff, i'm going to order some for my new 3.46LSD. Which ratio are you using ?

[whipsey]

have you got any drawings made up for the mounts my mates a fabricator but needs an idea of sizes etc

[alan335i]

don' know why it wasn't bleeding,it just came one nite first time no probs,think its a 3.91 diff,standard sport lsd anyway.little bit low geared,50mph @2000rpm,but liking the acceleration to much to change it.
