Looking for some guidance on my first EV project

I'm about to finish up a BMS which will allow me to use a stash of Li-Ion batteries, so naturally I want to make something to put these batteries to good use. An fun EV conversion seems like the perfect fit.

A little background on me: I hail more from the Electrical/Programming side of things, but I have some friends who can help me with some machining+welding.

I saw Arlo's DIY leaf inverter thread and decided I definitely want a leaf motor due to the power and low cost.

For a donor car I was planning to use a Porsche 944 as they are relatively light and cheap and have a pretty large engine compartment. Where I live, you can find people selling stripped down budget racing 944s with blown engines which probably would make great conversions.

For coupling a leaf motor I saw a couple of threads, one about clutch plates that had good fits on the output spline, and some detailing a machinable adapter for the net-gain bolt pattern. I'm thinking I want to retain the clutch for emergencies and if the leaf motor has rough starts.

TL;DR Question is could a semi-mechanically inclined guy mate a leaf engine to a 944 with some help from his friends?

(Budget's not a huge worry for me, free batteries + BMS, and cheap parts should keep the cost low)

Thanks, I hugely appreciate any help!

Added! Thanks for the tip!

Given you're in the US then if you want to get up to speed quickly then the course at EV4U is highly recommended;

3-Day Hands-On Conversion Workshops
I don't know if I'm looking for something like that. Mounting a netgain motor with an adapter is definitely within my ability. I am wondering specifically about the leaf motor, and how to mate it (clutch plate from another car, use a leaf transmission, etc)

I understand the course is very generic and if you want to get up to speed quickly on EV conversion then it's an ideal way to start :)

If you want to do the more traditional forum research then take a look at the various Leaf threads here :cool:
