Thread: Realistic Power Goals for bolt ons for a NA Series 3

Not really up for a top swap and dont wanna have car payments yet. Im thinking about doing a bunch of ZZP bolt-ons, 1.9 rockers, HV3 intake insert. 2.5 catted down pipe along with front and rear headers. I have someone that can tune the car for me and for cheap. Is picking up 50-60 hp from these bolts-on a realistic goal? IS it better to go with 3" down pipe, it is cheaper.

you could do all that and still not pick up 50 hp. even a cam won't net that much hp.

Unfortunately agreed. There's not really many gains unless you're going to port your heads and upgrade the cam and hv3 insert, but yeah, even then you'd be lucky to pick up 40. Not worth it unless you're planning on going turbo.

If that's the case id rather do a top swap. Or just swap in a whole engine

now you are talking

Depends how far you want to take it. You can make the n/a fun to drive with things like the hv3, er rockers (or cam), ported exhaust manifolds (or headers) with u-bend delete and a reprogrammed PCM along with some other supporting mods, but if your looking to truly make power boost is the way to go.
