Ell the MX5 has gone to get the 2.5l Diratec engine fitted, should be ready next week. Looking forward to getting back out on the road with it, then look at tuning kit.

Hopefully, it is a very common swap in the mk3 as they are prone to big end bearing problems. The 2.5 is almost a straight swap.

Hi there, I am just about to have a duratec 2.5 installed in my MX5 and will be searching the threads for tuning ideas to get the best out of the engine.
