Bently has great info maybe some one can send or post the info from this or

'87 325is Delphin Metalic
this is off topic but i was just wondering, how often should the timing belt be changed in an E30? i bought the car a little over a year ago and i havent gotten it changed. it says the last time it was changed was like 5 years ago, should i get mine changed pretty soon?
So after reading a bit... The s50 and s52 motors are M3 motors yes, maybe?
At the moment I don't even plan to use a BMW motor...
As soon as I figure out what I'm doing with the tranny side of the car It's gold... All I need to figure out right now is..
1. BMW tranny or T5
2. clutch disk and flywheel sizing.
3. How exactly to make the adaptor for the motor to tranny
4. How to hook up the speedo (that depends on what tranny I use though)
5. What needs to be done for the driveshaft.
6. Then other retarded minor details like power steering, coolant hose routing, other crap.
buuuuuut the project is still in the research/planning stage so I'm trying to absorb everything I can about the transmission and chassis side of the E30.

As far as LSD's go, they were a standard on several models, if not all. My baur had one.
So what about an 89 325i... factory LSD? Whats a Baur? How strong are the factory rear ends??

As far as the clutch pack goes, try to get a realistic idea of your hp projections beforehand, so you don't get something undersized.
Didn't even plan on using a bmw motor right now. looking to eventually make around 300whp. The flywheel on that motor is a 228mm flywheel, which is about 9in so I could use the factory e30 tranny with a 10 spline 228mm clutch disk (I read the factory e30 one was 215mm, M3 being 240mm) The clutch/pp set up should work.
As far as the bell housing, that would have to be custom made, but not too worried about that... I'm planning this with a buddy of mine who stuck a 350 in an old beetle (in the front not the back.. haha) and is now planning a mid engine LS1 into a Porsche 914... heh So we'll get that figured out so we can keep the factory starter, slave and clutch fork positions.
If the stock bmw tranny doesn't work, I can always use a T5. I know the T5 has been made to bolt up to the motor in the past

If I can use the stock tranny then the motor should fit without having to move the stock trans location so I can keep the stock driveshaft. how strong are factory driveshafts?
If I have to use the T5, it'll prolly push where the driveshaft mounts up so the driveshaft will have to be shortened and have a slop yoke welsed on then rebalenced...
You guys may know about this site... But this was show to me on another website. RealOEM.com Online BMW Parts Catalog
It's been real helpful in figuring out a lot of the other stuff on my mind.
Thanks for all the help so far. This forum by far has been the most receptive to my newb questions. It's nice to not have a few retards popping in and making a newb 'search' comment.
Keep the good info comming
