Good modifications for a 3.7??
 
Ok, so I have the puny little 3.7 baby engine. I just installed the Powerwire from Airram.com last week, and now I'm addicted to speed. I wish that I had the hemi or atleast a 4.7, but I don't and I'm stuck with this 3.7 so I want to try to maximize the power in my rig. I honestly do not know a whole lot about engines so I would like to hear everyone's input on the best performance modifications I could do. I'm not looking to spend thousands of dollars though, so keep it thrifty. CAI? Exhaust? Spark plugs? Jetchip? which ones? etc. Thanks.

Next step would to add a turbo, but that would run you like 5 boxes of ziti.


Oh only 5 boxes of ziti....I can afford that....

What does having the computer tuned do? and how do you go about doing it?

chris how much did the intake cost? did you also get an exhaust?

I've heard that in order to maximize the full power of the intake you need to really open up the pipes which means getting a new exhaust/catback system. How much truth is behind that? Will it really make a difference?

Also, can someone explain to me what a Jetchip it and what it does. Thanks.

Re: Good modifications for a 3.7??
 
so pretty much $400 for the k+n and the exhaust... performance wise would you say it was worth it?
