Dam wtf is Smurf trolling the Mazda forums..
Heres what I think on the 20B,Yeah its cool to have one,but I heard they still have alot of tunning problems.
13BT easy to find easy to swap,easy to get good power from
Or you can go with a 13BREW Or 13B Cosmos,but you will need to go single for it to fit,then rewire the whole dam engine bay for one..
shit for 10k you can have a bad ass 13BT ported/huge single/engine/fuel management and the list can go on..
