You need larger ground straps. That should do the job, and be far cheaper than a custom alternator. The stock alternator does the job. The additional ground straps cost me $12 at the parts store. A good solid electrically ground system should be configured, before putting a greater strain on a system that is not made to handle it. Quality over quantity. More amps on a system that is barely "held together" or a better ground system reducing elcetrical strain. Or both.

 

try summitracing i got a 180 amp alt from there

 

Hey, Ginger!
I have it on good authority that the NON TURBO PT Cruiser alternator is a direct bolt in for the 2nd gen Neons, and will work in your Neon with a plug from a 2nd gen Neon spliced into your existing wiring. This is a 120A alternator, whereas the stock Neon alternator is either 85A or 90A.
That being said, I would suggest you first do a big three upgrade, which consists of upgrading the engine to chassis, alternator to battery, and chassis to battery wires with larger guage wires, say 4 guage or larger. This will alleviate dimming light problems on a lot of vehicles with aftermarket stereos and amplifiers with moderate power output without the need to upgrade your alternator at all. Much better IMO than a cap, which I view as a band-aid fix.
