I was looking to see if anyone knew of any places that specialized in doing mazda engines/replacing them.

 

What are you asking?

I assume that you want to put a LS1 in an 88 RX-7 and would like to know if there are any shops that perform that service?

I personally do not know of any shops, but have a friend that did do that swap. Used a LS1 and 6 speed mated to a Turbo II rear end. The car is scary scary fast.

 

Not willing to do it yourself? I'm sure there are a few places around that will do them, but they'll most likely charge over 2k for the labor, plus all the parts.
go on v8rx7forum.com. i know theres a few IL v8 rx7 owners on there, i'm sure they'd be more helpful.
