Question Which engine or donor car?

Hi
I'm planning to swap a B230 into my 73 145, and run it with microsquirt. Yoshifab recommends a 1989 or later non turbo engine as the internals were improved geometries and usually the engines were not run hard their whole lives.

I have found a source of engines, with compressions tests performed for a decent price as a starting point.

My question is would it be better to start from scratch with an engine and a microsquirt? Or a donor car, to try and salvage all the rest of the systems to move over to the 145?

And which is easier to build from, the LH 2.2, LH 2.4 or LH 3.1?

If you don't have a motor yet, it might be slightly preferable to get a 93+ turbo motor. That way it already has the piston squirters installed, and it already has the oil return drilled into the block. Depending on the miles, a turbo motor run at stock boost levels hasn't really been beaten on very hard.

As for the ECU - it all depends on your goals. If you just want to run stock or near stock boost, might as well stick with the stock ECU systems, engineers spent lots of time getting them to work very nicely. However, if you're going to stray very far from the stock hardware/HP levels, it will b a little constraining. But Mega/micro squirt is still pretty DIY, you have to plan on doing a lot of tweaking, wiring, configuring, laptop tuning. Some people enjoy that as a technical task/challenge, some people look upon it with dread, depending on your goals and technical skills and interests, you'd have to decide.

Figure out your goals first and foremost. I have a 142 with a B23, and I started out just wanting a nice, quick driver. I built it up with LH 2.4, a 19t, and bolted it to the stock M41. Now I'm in the process of stuffing a big turbo in there, it's got a T5z, and I'll be going to Microsquirt. It's way easier to do it all once.

That said, if you have questions on the swap part of it, let me know.
