Prefer a freshly built motor or something somewhat new. However, if price is right I will buy a used non built motor. I am trying to put together a motor that is safe to boost to roughly 350rwhp. Let me know what you have. TIA

 

If you are going for that just do the bmw trans swap from k miata. Better spend of money.

 

That is something I will have to contemplate. I was really trying to keep everything within the miata family. But with some of these swaps becoming more and more cost effective I may have to rethink everything.

 

If you want 350hp nothing is cheap.
