335i Lazur Blue Moredoor - Borbets on all Road Legal P12

[Alex]

Ah, need a good day to fiddle about to be honest, its all new to me this m30 mallarky

[leeparkes]

An M30 is basically a big M20, same management, similar valve train design etc... so faults are easy (ish) to trace.
Im getting low to mid 20 mpg with the B10 and it was probably about the same with the standard M30.

M30 V's 24v.
Ive had both running side by side for say the past 2 years, fair enough the 24v is in an E36 compact but it weighed in at 1260KG which pretty much E30 weight (my E30 weighed 1240kg while it was still M20)
IMO they are two totally different animals, 24v is smooth, light, refined and efficient and is a good engine (if looked after) but they need to be wound up before they get moving properly.
An M30 is a noisy old slugger, big cc with 2 valve head design, heavy, late 60's roots etc..But IMO they are more fun to drive on the road.
Power delivery on them is nuts, standard M30's make about 200 lb ft @ 1500-2k and you dont have to wait for the power to 'come on. It will pull out of a corner hard from 2k and rev right up to 6k with pretty much a constant wall of torque.

As for speed my totally standard M30 weighing 1309KG (car in sig) ran a 14.5 quarter mile at Santa pod 2 years ago, still had the massive 20KG dual mass fly fitted.
Theo got similar times with his, iirc Zaust got 14.6 in his touring too.
if you are running it at York id aim for mid 14's.

Epic council activity Alex

love this pic



for fooks sake don't let mick behind the wheel of the M30 turd, being a 24v executive the torque curve could really scare him and cause irreversable damage to your seats

[magpie]

irreversible dammage to his tyres more like


that mid section is a two piece Alex.....

have you seen this to go with it ,cheap as fook

[Rtaylor2208]

Can't go wrong with that one above Alex bought one for my 325 last year and fits perfectly

[Alex]

Will get one mick cheers

looking forward to getting it on the road like

have you seen the cardboard number plate steve

Mick i left me wheel in your truck

Had a proper poke about in the engine today, and the wiring is far from my standard, plenty of block connectors, multi coloured wires and tape.

A few things ive noticed is that the cars fuel light is on and showing 3/4 full so something a miss there.

Rev counter doesnt work

The starter does not work from the ignition however of a switch, which i dont want.

First picture.

can someone identify whats going on here. it looks like part of the engine loom should all this be cut?



Inside the c101 plug thingy




On the starter there is a yellow and black wire cut and then another one attached, is this the council starter switch

there is also a green and black one that been cut



this is in the fuel injector wiring any idea



should all these wires be here?



the heater hoses havent even been connected.

where would these take the feed from



more mess



any idea what this connector is for and what the little hose with a screw in the end is suppose to be for



the engine runs rough at idle, when i remove the oil cap the idle doesnt drop which suggests there is an air leak somewhere however i want to sort all the messy wiring out before i start pulling the engine apart, some of the electrical connections really dont look like they will last very long and are allready falling apart

Allready started removing some councilness from the engine bay





Some Morsels for it

[pacerpete]

Sorry Alex, that is scrap. Alas, the latest in a long line

[Jhonno]

Definitely looks like an M30 neanderthal has been at that wiring!! Ditch it and start again..

If only you'd started with a proper lump..

[leeparkes]

That wiring is messy.

In your shoes id just get another loom rather than tackle that lot, cant understand why there are so many cut wires as an M30 will run plug & play you only need to cut two wires to get the rev counter working.
M20 looms work on these engines if its any help.

That hose with the screw in should attach to either the FPR or it plugs into the the smaller hose next to the large AFM to TB hose.

Small hose is part 13

[Karan]

It's amazing how people get even the simplest wiring cocked up,

Copper scrap ahoy

[rob0r]

Definitely get a new loom! The wiring was probably the easiest part of my 335i conversion.

Would that make me wrong for soiling a sock to the images of lazer blue 4 door correctness?

More pictures please!

[Alex]

are the looms pretty simple enough to change ?

so what do i need an m20 or m30 loom ? are all m30 ones the same ?

[Jhonno]

Well you'd have to question the IQ of the chap, given that he decided to drop an M30 in, in the first place..

[Alex]

Haterz

[magpie]

should keep you busy for a while

[Alex]

It will do

Shame as i wanted it on the road but want it right first

[leeparkes]

You need an M30 loom, manual if possible but auto can be used if you swap the TPS plug. Make sure the loom you get is from around 88 to 92,later looms have a different C101 similar to M50's (which looks like what you have on now.)
M20 loom can be used but iirc some wires need lengthening.
Yes its fairly easy to swap over.

Btw the plug you mentioned earlier is nothing to worry about, im not sure but i think its for a lambda sensor which isnt really needed on these donks.
What number ECU do you have?

[Alex]

Not sure on ecu number

Ive put up a wanted advert see if anyone has anything

[capri_rob]

jesus Alex thats proper botchery


Hope you've got a soldering iron

[johnl320]

Here is a shot of the wires needed to make the m30 run the ones cut and tucked behind my finger are mainly unused auto loom ones, your car won't be exactly the same, as mine is a chromie but it gives you an idea. If it was me I would be binning that loom and going for an m30/20 one.
On another note, if that is the state of the electrics I would seriously check the state of the home made engine mounts.

[Alex]

Ive seen the engine mounts and to be honest there pretty good

[johnl320]

sweet, just the electrickery they struggled with then

[Jhonno]

Pics of the mounts Alex?

[leeparkes]

Pics of the mounts Alex?

+1

[Alex]

Will get some next time i'am out

i belive the last owner bought the engine allready with e30 mounts then wired it in

Not botherd about these issues to be honest as its still saved me doing an engine conversion that i would of never of got round to doing

[Rav335uk]

Fook the haterz Alex, ill try to sort out a loom when i get back from Venice from the lads over on the irish forum, theres about 4 m30 breakers on there atm mo, if you cant get on by monday.

[Alex]

Cheers rav, The can moan all they like i dont care. might go to topless's on Sunday if the weather carries on and get a loom off him

Plan so far

new loom
Ive figured out how to connect heater hose
Fit 324d Washer bottle
e28 Airbox
4 pot wiring covers
m3 battery tray cover
Paint inlet and rocker cover silver.
DANTHE fan loom and possibly new fan
HT lead covers
and a bloody good clean/polish under the bonnet.

Hopefully should look "OEM" ish

[magpie]

will you ask mr topless if your going to see him for a front screen he has put by for me and i'll pay him no probs.

i'll pick the screen up when i drop your wheel off and i've got d'monds m52 fannymoulds to drop in to him on the scenic route .

so if you get the screen it will speed things up a knot

[Alex]

Will do see if i can be arsed saturday night

[magpie]

make sure it has a blau tint Alex
