aight fella's, I got a 90 rex si, all stock... i pulled the motor for fun, you know, just to learn alittle, and the tranny, block and head are all pulled off. the question is: while i have everything pulled apart, is there anything i should replace maintenance wise and performance wise (remember its a stock d16a6)????? heres what i already am doing: the head and block are being cleaned and aligned or whatever by a machine shop, the flywheel is getting lightened. new water pump, all new hoses, new clutch.... is there other things l should do now while i have everything apart... like any cheap performance parts or anything? will a 421 header on this engine help any with the stock exhaust? thannx :worthy:
