E30 diesel or s50

[brianf408]

I've been on the fence between that and an s50 sadly. it seems like the m21 is the only one available to us and they have their own faults. i like the uniqueness that a diesel gives. if you know any info like switching out the fuel lines for diesel and the diesel pump etc. I want to get a jest about diesels before going with it.

I think the fuel lines are re-usable, but will require a different pump, filter, etc. I like the uniqueness of the diesel, I don't want raw power, just something fun and different. Also planning to swap my Land Rover to a 4bd1t whenver the v8 dies, I guess I just love diesels.

i have an m21! thinkin about mabey selling it. its pretty cool motor looking at it. so similar to the m20 and about three times easier to work on if you can imagine that! go for diesel! put a little bigger turbo on it and turn up injection pump and you should be happy with the power.

Just the engine itself? Or pump/ecu/etc?

I think a slightly bigger turbo with an intercooler would make it a fun little engine.

Does anyone happen to know, would this require a getrag 260? Or would it bolt up to the 240 without issues? Mostly concerned about the angle of everything.

When I was looking up the diesel swaps if its an m21 it will bolt up to the g260. a guy over in Europe did it I believe that's the best thread I found so far.

By the way I think it was on the e30 tech website for future references.

I've done a coupe and an iC here in the US with an M21...you can google Al Taylor BMW for some articles on them.

I raced the coupe in BMW club racing back in 2003, stock, just turned up the fuel and ran biodiesel. Ran a 260 trans. Easy conversion...on the iC I used a 262 4 speed out of a 3.0CS, euro ex manifold, reversed plenum for straight intercooler routing with an AUDI intercooler mounted LF. Had a factory hardtop on the car sometimes also for a unique look. There are photos on the web of the car on track with a huge black cloud behind it. Set a east coast land speed record for biofuel with the car. Last thing I tried was straight grease at VIR a couple years back, FI pump started leaking so I yanked it for a regular M20....

The iC was about the same as a Spec e30 as far as track performance.


I have a bunch of 524Td [parts if anyone is interested.


Thanks

Hmmmm.....tempting

Too funny...I just set a 2.4 td/speed in the engine bay of my e30 last weekend. Pretty much a straight bolt in. Need to get my lazy ass off the chair and order tranny mounts and driveshaft support bearing. Would love to intercool it but...might be more hassle than it is worth.
My goal is a maximum mileage car. It is an easy swap.
