im swapping a 03 mazdaspeed engine into a 1990 miata i already have the rear end and tranny swapped in as well as the wiring harness from the 03 in getting the new fuel pump and hat and everything for the need of a fuel im not very knowledged on these cars at all im a mechanic for a customizing shop so with that all said if anyone can direct me to a thread or somewhere that this has been done so i can properly do this swap without all the headaches and thought of forgeting anything any info would be greatly appreciated and i appolagize if this was already discussed on here before

 

can't say I have seen it done myself. But a couple other resources would be our sister site: miataturbo.net or possibly old man miata.net

Good luck with the swap. I bet, it's similar to just a 1.8 swap where you need to upgrade your rear end (VLSD suxors) and with a MS probably the wiring harness and ECU or standalone. Go standalone and you can forgo a lot of the emissions stuff.

 

its a customers so it needs to be stock ---- just wanted the swap done not gonna lie this little car has been bein a pain in my **** and thnx
