Honestly, if you don't have the time or patience, then don't even start on a project like this.

Every single guy out there who's done an engine swap has had to deal with some issue that doesn't have a mapped out solution on the interwebs. Fitting a motronic 1.8T can will pose a lot of fabrication challenges to getting a near 40 year old 924 back on the road (error codes/gauge display?, stock 924s ran hot--->cooling solutions?, clearance issues of the hood and engine bay, exhaust mating?, etc.).

I'd sell the 924s and the Jetta then just look out for a 924/944 that someone has already built up.
