My M30 conversion so far: SHE's ALIVE!

[blingsta]

aint it a good feeling !!!!

[winx]

awesome! well done, sounds like a WW2 fighter!

[ric325i]

i love hearing it without the exhaust it sounds great! when you rev it your ears bleed!!!

i think jaffro took his around the streets with no exhaust and no bonnet too

congratulations man. get it all hooked up and take her for a spin.

[Rav335uk]

problem now, with the e30 side of the c101 plug, can't get the heater and windows to work.Went through the m30 gide and cut the right wire, but that seems to be any good, any suggestions?????

[Rav335uk]

All sorted now. wiring done.Flange done on he exhaust, all thats left now is the prop and exhaust and get the inside back together, and take her for a spin

[blingsta]

I took mine out for its first spin today !! gotta be honest and say that i much preffered my 2.5 turbo conversion!! it just had so much more Umpffff... dont get me wrong, she went well and had loadsa torque, but i just miss the push in the back at 3.5k rpms.

What rad and cooling are you using mate? did you go for the M535 rad and leccy fan ?

[Rav335uk]

No, used the e34 rad and a lecce fan that needs to be hooked up.How did you hook your fan????

[blingsta]

im also using the E34 rad too.. i had to buy a fan switch kit and its a straight forward wire up jobby... i can pm you details if you want... do you have a fan switch kit? ive got a spare brand new in a box one if your interested?

[Rav335uk]

I was going to use a relay and wire it up to the temp swith on the engine.
Of the subject a bit, did you change the temp switch from the back of the m30 engine for the m20 one as the both have a sungle connection on them both????
I haven't changed it as they both looked the same, or are the resisitants different for both engines????

[blingsta]

M20 one has one pin on the switch and M30 one has two... it needs to be swopped to the M20 one for the gauge to pick up a reading
you wont be able to get the fan to work by linking it to the blue temp switch!

[Rav335uk]

no mine on the e34 has already got a single pin one installed with out me swapping it.
Hoe did you connect your fan then?

[blingsta]

Good bit of kit this... and adjustable from 40 degrees to 100 degrees, so you can make the fan kick in early (below half way)

[Rav335uk]

Saw this yesterday, but wasn't sure, will see how we progress tomorrow, i mean today, and if i get stuck you'll know by about 12.00 pm if your logged on.
Anyway what do you think about the temp switch, shouldmi change it or leavt it, and did you use the m30 loom or the modified m20 loom????

[blingsta]

i used the M30 loom mate.. i will prob be sleeping at that time as i finish work at 7am... but if you need it, its brand new in the box and i will take £20 including the postage for it ! drop me a pm if interested.. and i would take the chance and swop the temp switch to one from a M20.. just to be sure

[Rav335uk]

ok mate will swap the temp switch over tomorrow and pm you if i need that relay.
What diff did you use, as i've got a 3.46 open atm, with the m20 prop on after we change over the flange on the gearbox

[blingsta]

mines a open diff at the moment to fella, but ive got a 3.64 LSD to put on ... just need to get it on a mates ramp when he gets a minute... what prop did you use?

[Rav335uk]

My origional one is going to be used as I read it can be, its of a 320 cab.Should be ok as you Turbo boys still use origional props with big horses or am i mad.
Whats yours like to drive, does it have the nuts to see of a scooby???
And are you planning on a turbo for it.
My next one after this is a e21 m30 conversionas a sleeper

[blingsta]

Gotta be honest mate, as mentioned above, i sorely miss my 325 turbo .. that thing was a animal.. if i decide to keep this car, i wont turbo the M30, i will convert it back to a 2.5 and turbo the M20 lump, The M30 has a dogleg gearbox which i dont think i wanna get used to !! im actually contemplating selling the car now as its already financially hitting me ! now got 3 cars on the drive and i cant really afford to run all 3 !

[Rav335uk]

Whats yours worth?
And what you going to turbo, m20b25
Why not turbo the m30, as i understand it can take 300 bhp without doing any internal mods which sounds good to me

[blingsta]

mines a 1992 Kreg cabby, reckon worth about £4-5k.. and i just loved the reliability and torque i had on the m20b25 with the turbo.. that block is also good on standard internals for upto 350bhp !!

[Rav335uk]

Right then, only got the prop and exhaust to do tomorrow and put back the inside then off for a spin, but first thing id=s the electric fan wiring.If any of you have a diagram without using a elec kit, I would appreciate it.

[blingsta]

so simple do wire up mate.. you need a electric fan temp switch.. like the one ive got.. live, earth, ignition and temp switch !!

[Rav335uk]

Ok mate, will let you know if we get no joy doing it the way they suggested down at the garage.
I suppose if they can't sort it out it'll sit there a bit longer

[Jesus325iTouring]

Been quite a task this,made a good read this Rav,here's how my engine went in,Scott guiding,me taking pics and messing about with the crane

[blingsta]

you didnt keep the viscous on there did ya??

[Jesus325iTouring]

Yeah we did,was a bit tight I must admit,but nevertheless went in all in one lump

[blingsta]

cool. did you use the M535 rad? and i take it the engine is in pos 3 ?

[Rav335uk]

What did you replace it with , another m20 defo not a m30???

[Rav335uk]

Right, also has antbodt used the origional e32 wahser bottle, as I found this too be a great fit where the origional bottle sat without interfering with the airbox.

[bmw-mad]

Great progress Ray seen you and the car the other day Wheres these pics of the e21 you mensioned

when you going to have the cab finished?

[Jesus325iTouring]

cool. did you use the M535 rad? and i take it the engine is in pos 3 ?

I'm all confused now,are you asking me this? If you are,then no,it's just the standard B25 rad given the replacement engine is the same as I had before, M20B25,answers your question too Rav,that is if you were asking me too

[Rav335uk]

Soon Mr MAD soon, lee has been telling me he had my diff for ages, and guess what, it dissapeared and no one knows where it went, so thats the hold up so far.Me and matt are fabbin' up the exhaust tomorrow and hopefully sorcing the prop aswell.Thats the only 2 main issues left, then it should be drivable.Plus having my brakes grooved by the engineering company that did matts.

E21 being picked up end of next week as I got to sort out the storage for it.

[Rav335uk]

Great progress Ray seen you and the car the other day Wheres these pics of the e21 you mensioned

Cab should be done for the weekend, props in place and bolted, had to go for a custom prop £80.00 all in, front end e34 and back m20, exhaust is on and started up to make sure there was no leaks, all good on that front.Needs to be blead now and also a switched live to make sure the fan kicks in when it should, and then for the test drive in the afternoon .Everything else is done.

E21 pics comming when I pick it up.

[ImysE30]

Just had a read through and sounds awesome mate
Enticing me to put a M30 in mine now

[Rav335uk]

Fan working today,no problem at all.All the rest of the wiring is now tidied up, car washed, and now tomorrow, TEST DRIVE TIME!!!!!!!!! .
All service lights have been reset, and all fluids checked, then I ran out of time, got dark nad too much Friday traffic about to go and have a blast.
Bloody fog lights still giving me problems, will have to sort those out at a later time i suppose.
Will post up more pics tomorrow of the finished job.
