03 GT 4v need more power!!

supersnake730 · 10-07-2009

I have a 03 GT with a 4v from a 03 mach 1 with every power bolton headers,throttle body, pulleys, tune, etc i want like 30 to 50 more hp out of it what are my options?...not nitrious

..10.1:1 compresion ratio so cant put a supercharger on it to risky

.. cams are expensive so are they worth it any other alternitives

what other parts and components did you need to complete that mach 1 swap?

cams are definitly worth it, good for power and a lovely idle. porting heads would be another option that would help in the power dept. oh and a meth kit. those are about the only options i can think of at the moment. aluminum driveshaft & lightweight flywheel won't add any power, but could free up a few ponies that are being reeled back by the stock components.

I swaped it from a mach 1 that rolled but i just took the motor an tranny from it an just swaped it in with the ecu an but other than that it was pretty straight forward was a stright swap in just need that parts car

iv heard a definate 30rwhp gain but do i have to change any of the valvetrain or can i just swap the cams

well from what i understand it depends on what size cam you go with.... a street/mild cam shouldn't require valvetrain modifications, but a race cam or something obviously would.... shop around and make a few phonecalls to the companies techs and see what they reccommend, just don't let them upsale you too bad

I know ford sells a 4v cam kit (Ford Racing #397-M-6550-T46) it comes with springs, valves, all the valve train an how good are the cams it comes with or should i look else where
