no problem. that site has LOADS of helpful info and a lot more Mazda enthusiast that are willing to help, all the mazda peeps in this section are mainly rotary peeps.

also something else you might want to look into.....if ur engine is still in good shape (meaning you haven't blown a hole in it.....look into forging the engine and turboing it....

i'm not sure if the 00 protege's 1.8L are the same as the miata 1.8L, but if they are i know they will hold boost from turbo's real good.

or a BP-T swap.....
