[brian325i]

thanks eko

?

You may aswell take the M42 PAS pump out now,you wont be needing that!

[Jimbob]

Good progress here mate, bit of a crazy time to be doing it with uni exams coming up though, fair play fella!!!

I got my M20 ready to be lifted out yesterday, just waiting for my mate to get here to give me a hand then it's up the scrappy to get the oil pick up pipe then prepare to fit my M52

Very nice car by the way!

see the corner of the rockercover..snapped off..back part by the bulkhead..

powersteerin pump is loose just bolted so i dont lose it..thought it might fit though..i presume it wont..

@jimbob..thanks for the comments..ya the whole college will slow down the progress though when exams come in 3 weeks ish

You can swap the cam cover for the M52 plastic one (weighs less )

I have 2 in my shed now

Bit greedy arent you

.........want to swap one for M50 standard

[DanThe]

If yours is Non Vanos it wont fit Eko, but I do have just the thing





Freshly powder coated and look how clean the inside is



£20 exchange to E30 owners
£30 exchange to E36 owners

Lets face it, they obviously have more money

[eko]

Dan i have a spare non vanos cover in the shed that i was going to paint Black,yours would be even better.
Let me see how funds pan out this week,got to buy arches and maybe sills yet so.............

[brian325i]

strangely enough my friend has an m52 plastic rocker cover..guess where that will be going ha ha..

straight fit on to mine ya?? lightweight anyone able to tell what prop ill need from the pic of my gearbox end????its e36325 gearbox and you can see the end from the pics i rhink

[eko]

as above,you need the E36 325/328 front half mated to E30 rear half using a modified E30 centre bearing!

[brian325i]

@eko ..i thought it depended on the output shaft..thats good news..thanks..looks like i need to find an e36 325 beig broke..gearlinkages , prop , powersteering pump..

is the back half a normal e30..ie will my 318is do..

i read bout the centre bearing issue in m50 developments thread and doesnt seem scary

thanks for your help

Looking at your pic iyt looks like you have the larger guibo pattern hence needing the 325/328 prop.
M50 320/323 uses the smaller one!

Think the 318is rear will be ok,pretty sure all E30 rear halfs are the same?
I used an M20 one with no problems.

[brian325i]

thanks eko..i got pics of me driftin my other e30..has nothin to do with the conversion just said id share em..it was my first round so no angle or smoke but still sideways




my friend called with the m52 plastic cover..he said he tried it before and it wouldnt fit

and that we might be able to swap e36 bracket to m42 powersteerin pump

[eko]

Cool pics Brian,looks like good fun

Why use the M42 PAS pump,do you not have the M50 one?

[brian325i]

ya its just if i can modify and save 50 euro then itd be worth it to me as im a student whos broke and every cost that can be avoided i try to avoid it..

the drifting is excellent adrenaline rush alright..picked up that mkI sport for 500 euro..

what would ye suggest to clean up things like the oilfilter carrier..the altinator metal case the vanos metal thing and all other alloy bits

[eko]

Well id use autosol and wire wool but others may differ!

[m-dtech]

i found it easier with the m50 to remove the front cross member , bolt the engine to it and then put engine in from underneath saves you damaging that clean bay !

m

[m-dtech]

just noticed the gearbox / prop problem...........

Why dont you use the m42 gearbox and a e30 325i prop ? (thats what i did)

this means you have better gearing and you can use a normal e30 diff.

[DanThe]

No reason why the M52 cover wont fit, both vanos engines use the same cylinder head

[brian325i]

i will be using an e36 325 front prop and normal e30 back half with normal e30 diff just modified centrebearing podition

rocker cover i will check it and see if it fits , fingers crossed.

mdtech..lovin the idea bout droppin subframe...how high wud car have to be jacked though

[eko]

Brian,mdtech has a point about using that gearbox,saves hassle with diff ratios?
Thats the way ill be doing my next one!

[brian325i]

why ? what way does it drive with e36 325 g/box and 318is diff??

i thought the flywheel doesnt match up..if it drives ok id be happy..i dont mind a top speed of 125mph..thats the difference isnt it????

The ratios in the M50 box are awkward.
I ran mine on a 4.10 diff for a while and it was an experience.
First gear was a waste of time,just revs everywhere and topped out about 105/110mph.
Imm using a 3.46 diff now and although not perfect it is much better!
3.25 from an E30 M3 is ideal.

[brian325i]

i presume you get much better acceleration though do you??1/4 mile time?

i could live with 110mph until i sourced another diff.i have an e30 mkI sport dif if thatd be better

[eko]

Shit hot for acceleration,dont know how long itll last though
Sport diff will be better,not ideal but definately better!
Infact,if your not too bothered about over revving then could be a good compromise between acceleration and motorway speeds
Mine still gets off well using the 3.46 though

[brian325i]

when you say over-revving...is there much difference?? say at 60mph=normal m50 is 2500 but in e30 it be what???3500??

still limits at 6300-6500..anyway of bringin it to 7..chip i suppose

[eko]

Chip takes it upto about 6750rpm i think?

70 was about 4400rpm from what i remember!

[brian325i]

o-100 so with the way my gearing will be should be a nice bit faster than an e30 318is

4400..bloddy hell..she must accelerate fast so up hig....60-110

Trust me when i say itll leave an iS

[Brianmoooore]

If the diff ratio is inappropriately high, it just effectively moves the gear positions down one. Fifth becomes fourth, fourth becomes third, etc.
Unfortunately, this just leaves you with a useless first gear and effectively a four speed box.

[Jimbob]

I'm using the 3.64 diff, I wonder what first will be like just as well it won't be my everyday car.
My 5 series oil pickup pipe is cracked so I'm stuck now the M20 is out, no forklift drivers up the scrappy on a Saturday

Brian what sort of progress have you made since your last set of pics? It seems to be coming on pretty good mate

[brian325i]

i organized my tools ..which took bout 3 hours as they were scattered all over the garage..

i tcut and meguire polished one side of the car..

i really had a day of "procrastinating"

today im gonna fit the e21 g/box mounts
the e28m5 engine mounts and the alloy e36 mount

and take off my exhaust

and have a look at the drop the subframe idea of mdtech

@eko is first gear really that bad??not 30mph like normal i get but does it just do 5mph or something??

[m-dtech]

The m50 flywheel fits inside the m42 gearbox no bother at all, compare them side by side and you will see they are same overall length.

This means with the 4.10 diff you have just now, and the IS gearbox, you get a car you can drive daily and RPM that sits normal on motorway. oh and fucking awesome acceleration

[DanThe]

Your tech1 sport diff (3.64) wont be anything like Eko's 4.10, should be ok to live with if you dont use the motorway to often.
Ive got a Viper 2 chip in mine and the rev limiter is raised to 7200rpm although I rarely take it above 6800.

When I fitted mine I slid the engine and box underneath the car on the subframe, lowered the car back down onto axle stands and then raised the lump with an engine crane as I didnt have a load leveller.
