I'm currently looking for a mk1 Miata as my first rwd car, I'm also looking at more na power mods, I've seen mention of the mk2.5 bottom end, 99 cylinder head but I can't seem to find anything easily here. Can anyone point me in the right direction of proven power plant recipe's? Is their a thread with various options and price points?

I'm not used to people quoting whp, would I be right in thinking 150 whp would equate to 170 bhp at the flywheel. And therefore a 0-60 time of about 6.5 seconds?

Cheers james

I'm still looking for the answer, but while looking on google I found my own post near the top��
