Just like everything after my 2000, stuff that cost money was dumped in favor of cheaper assembly.
Discounting the SVT manifold due to complication of implementation it is best flowing factory manifold and can be had used or new fairly cheaply.
300hp isn't difficult to attain. Keep build cost low and focus on quality hard parts and the best tuning you can buy.
Thank you but I am still looking to know if 2k intake manifold with for example 65 mm TB from focus central will work on 2003 car if I swap it
the only concern is cables that are for TB if they are different for 2000 style TB then 2003
