I recently purchased a naturaly aspirated (NA) 87' RX-7 and was planning on swapping the engine with a rebuilt turbo 13B and a new transmission. I have looked around on the net and cant find if its possible to do this on a NA model. If anyone has any info they can give it would be greatly appreciated. I'm planning on spending at least 4k on the engine and trans, including labor for installation, if this seems like a reasonable estimate confirmation would also be nice.

Thanks.
