hey guys thinking of what parts i need to get. im building a L16 turbo to go in my 1200 as they alow an L16. i was going to put stock L18 guts into a L16 and use a L20b head. i have a redline webber mainfold that i was going to make up a plenum for and turn it into a efi manifold and i have a T25. what throttle body should i use? what stock injectors should i use? and how much boost will the factory bottom end take? im trying to use as much factory parts as possible to cut price down and availability
obviously im going aftermarket ecu

oh yea how do i work out plenum size?
