E30 parts to be made

[F34R]

I am completely with Nando on this one. I would LOVE a 24v m20, but the simple fact is; M5x/S5x or purely a refresh and forced induction on the m20 is 1/3 the cost of what a custom start up 24v m20 head would cost. It is not even close to being a bolt in, you would have to go MS just to manage it.

The e30 has plenty of engine options already.

I think wheels are more of an issue:

I would like to see some better wheels made for the e30. Something in the 16x9-10 direct fit pattern, et10 57.1. I want some proper track wheels! 6UL wheels do not have a 16 or anything in a 10. Prices around 200 per wheel and under 16lbs.

BMW already made a 24v M20 - it's called an M50.

This this this.

I know you said no 5 lug swaps but for awhile Ive been wondering how hard it would be to have some wheel bearings and hubs machined to 5x120. Also the brake rotors would obviously need to match. But if you could source a manufacturer that sells rotors with the same dimensions as the standard e30s, the only difference being the bolt pattern then a 5 lug swap would only be as hard as swapping wheel bearings.

Yeah I have been looking into 5 lug stuff. But what is acceptable for my car I wouldn't put on others. So I would need to find a cheap enough low labor solution. Still working but don't expect it to be for sale. That is a lot of liability also that I don't want.

Hmmmm... in that case I might just take an engine rebuild class next semester and rebuild an s52 if I got the money.

What is the benefit to an adjustable shifter? I can't see the need to adjust the throw on the fly...

Because then one shifter would suit everyone. Some may like a longer throw with less notchiness, others may prefer a shorter throw and more notchiness. One person may prefer shorter throws for track/autocross and like it longer for daily use. And some may prefer a taller or shorter shifter than stock, which can both be done with the same shifter if it's adjustable. I've seen a height adjustable shifter but ever one that can adjust the throw.

or some may not want a short stubby notchy shifter at all, and realize that increasing the length of the lever on the other end of the fulcrum is the way to go.

racing dynamics made a 24v head for an M20 days ago. reproduce that!

This would be the coolest thing ever.

That's exactly my point...even though there are many shifters you can use on an e30 there's still gaps in between the jumps in throw/length that an adjustable shifter would fill.

Make 5x120 wheels too? 17x10 possibly? I like the offset your thinking of, but the hub would have to be 72.5mm. I need track wheels for my e28!!

I also vote for an oil filter relocation kit. The stock location stinks and can be a pain for some to get too. The empty 'shelf' where the cabrios have their battery is one option....fabricate some type of bracket to bolt down which would have a provision to place the screw-on type filter. Maybe in the upright position so when you remove it very little oil drips out.

The 24V M20 head sounds great....but that's a pipedream at best. A huge investment will be needed to get it started then you need to have enough confirmed orders (i.e. deposits) so the person behind the project doesn't take a bath in lost capital. **edit - and for some folks where emissions testing is a pain to deal with (read: Calif), the 24V M20 head could get you a failed smog result based on visual inspection alone**

The oil filter relocation suggestion wouldn't require nearly as much to make a reality....and in the end, the price will be obtainable for a lot more enthusiasts.

What are some things that the e30 guys would like to see made that isn't yet? I'm looking for another project and would like to make something and make a few extra to sell here. Just so you know I have a smallish machine shop so no cnc or anything like that but I'm pretty capable. Just looking for ideas.

Ps don't say 5 lug or body kits, thats too big for me.

Rear axle carrier with 12 degree sweep angle and contol arms to go with it. :)

24v M20 head.

Well if your gonna dream....dream big
like a rotary valve M20...14000rpm would do the job nicely

[tinkwithanr]

Rotary Valves would be very slick, I wonder what the durability is with that setup.


And I agree with Nando, trying to make a 24 valve head for the M20 based on hoping to make a profit would be a pretty dumb idea. Considering the work that would need to be done, it's just not feasible.

The only way it would ever happen is a one-off type scenario, where someone wanted to do it just to be able to say they did.

"Just so you know I have a smallish machine shop so no cnc or anything like that but I'm pretty capable." from OP

All these ideas are sweet. but require cnc. unless you can fab by hand a 24v head... I wouldnt want it on my car. do much detail to mill by hand... wheels are a possibility depending on machines he has.

the shifter is realistic.. Just sayin.. dont wanna be a jerk.
