My suspension's all together (besides the Cusco FUCA's, still waiting on delivery from Japan ). Time to move on to the motor and i'd love some advice. I put together a list of everything I think I need, the budget is $15k and most of it will be installed and dynoed by Import Builders. I'm hoping to get everything ordered as soon as possible so I can fire my REX down to IB's. I provided links for easier browsing. Please voice any opinions about the list and any parts i've missed or don't fit the b16a, I can never have too much info. Again the primary purpose is road racing. Thanks guys! Couldn't do it without you.
