I would wait on the cam. You can extract horsepower from many other areas before needing one. Having the head ported and polished produces nice numbers. I would also suggest getting a high flow cat before getting a test pipe. Test pipe is only needed after turbocharging. A larger fuel rail would be good after switching the intake manifold and putting a larger throttle body on.

 

I do have a bored fuel rail and am planning on the high flow cat - no test pipe for me. I would lose all my low end torque with that.

 

Ok, cool. Another nice gain is produced by switching to a 501 maf, but it needs to be tuned accordingly. If you're eventually going turbo I would save up and not buy anything else until then. Spending a little here and there adds up quick. That's my biggest vice!! I'm always telling myself, "that's the last thing I'll buy for awhile." It doesn't last more than a week!! I'm addicted!!

 

True - perhaps I'll just get the IM, hi-flow cat, rear strut, sway and coilovers. That should make the car more fun to drive for another year or so

 

what is a 501 Maf

 

The 501 MAF is the mass air sensor found on the 2000+ Eclipses and newer Galants with the 4G64 engine. It is less restrictive to air flow than our 605 MAF. Here is a thread about it:

Hope this helps.
