Sure, if you can tell me input shaft length I can start reverse engineering from there. I can't imagine it will be too hard to figure out.

Re: RWD conversion with an AX15, help me fill in the pieces

I'm using a 2.2, mainly because I have piles of spares from my last lemon's car ('89 daytona). I thought about a 2.4, but that's going to require a larger cost of entry. I have all these parts for the 2.2 already. Computers, accessories, turbos, internals, etc. Makes no sense to throw those out and start over when this is supposed to be cheap car racing. If I did eventually switch to a 2.4 the MA5 works with that as well, so that's one more check box towards that direction.

The 2.2 was fairly decent in lemons once I learned it well enough to keep it alive. (they do not like 7 hours straight of WOT full boost). The biggest issue with the daytona was the lack of any good suspension or brakes. This engine in a chassis that can corner will be fun and probably competitive in Lemons.

Plus I have to keep my masochist reputation alive.

Wowsers! Here's my other question. Why not start with a 2.4L engine with twin cams? Or, you want the 2.5 because it can run on a carb?

Lol, no 924. I owned a 1987 924s for a while. Never again. Nightmare cars to work on. It's an E36. Started life as a 318i.


I think i've actually read that thread. I know the R154 works really well, but it's a cost of spares issue for me. I know I'll need to replace transmissions at some point. I see MA5's for $300 fairly frequently, and close to me, but i've never seen an R154 for less than $500, and usually far away.

Don't tempt me. I think I want to stick to the MA5 or AX15 purely from a cost standpoint. This will be used for racing and it's cheaper and easier to find one of those transmission than it is to find spare R154's, and I do need at least one spare.

The car is german. From the 90s.

I also want to point out that you have hedge clippers sitting in the engine bay of your junker racecar. I think that means you're doing it right!
Lol. I was trimming branches from a neighbor's tree that were intruding into my driveway. But i'm sure I could find a use for them on the "racecar" too.

Re: RWD conversion with an AX15, help me fill in the pieces

For fun, here's my first test fit last night (before i went through the effort of leveling it). Naked block, naked head (both are junk pieces) and the dakota trans. Goes in with lots of space (which will vanish as I start adding accessories. Bonus points for identifying the car.

I'm going to have to do custom intake to swap the throttle body to the other side, which will be fun.

On the MA5, you will want one from a solstice/sky as they will have the remote shifter that sits above the output shaft of the trans. The colorado unit is like a T5, with the shifter bolted directly to the transmission. Its worth a look for shifting ease. The truck/coupe trans both have the exact same gear ratios throughout except for 3rd. The truck has a wider spread.
Good to know on the shifter.

Can you tell me what you ended up doing to mate the MA5 and 2.2/2.5? Any input shaft mods? what was your starting point for a clutch or is it purely custom?


Also, I notice the Dakota bellhousing doesn't have the timing window that the FWD cars have, but instead a pickup hole. Does that mean I do need a dakota specific flywheel?

Re: RWD conversion with an AX15, help me fill in the pieces

I guess I'll have to just go measure for how much needs to be drilled. I can't find any info sitting online.

I think i'm going to make my own oil pan. I'd rather make one that fit my application perfectly instead of just deal with whatever the Dakota one does. Should be easy to cut a FWD pan and weld on a new bottom shape (and accompanying pickup)

Make sure that your crankshaft is drilled for a pilot bushing. Everything else bolts up. There is also a RWD specific oil pan.
