They claim to offer the swap to the public on their site I've got a spare 13bT motor, and a spare miata body.... WTF should I do with them?

 

Why dont you contact them here.

 

Cause I don't wanna waste their time when I'm not buying one. I figured someone might know. Not a big deal.

 

Next time I need my car rotary miata will be one of my strong candidate, but it should be NA for me

 

Scott at mazsport is currently putting the finishing touches on my car (FD).
You know that saying "you get what you pay for"... well..
They are the people you go to when you want it done right the first time.

 

He quoted me over 4K on the phone for all the pieces, minues of course the drivetrain, etc...

I installed my motor for less than 100$ worth of materials. I didn't make an aluminum oil pan, but then again, I saved 3900$

I must say he (Scott) was quite irritating on the phone, asking questions about my engine placement, assuming I was some ricer, etc... Whatever, GT40 powered S5 motor'd miata awaits paint today!

 

Nice. I was really considering this swap and using a t-66 instead of the gt40. I even mirrored the old rotary miata site on my site. Post some pictures of how you have your engine mounts and drivetrain. I saw some on the site but put close ups of the underside of the car and mounting area.
