You’ve spent the last year gathering up all of your supporting mods and you want to go Big Turbo, but you’re on a budget. We completely understand that, and have chosen the two best bang-for-your-buck Borg Warner turbos available for your Neon SRT4.
This is an AGP Big Turbo Kit, but stripped down to the components you absolutely need to run it. There is NO overflow bottle, NO heatshield, but still has all the clamps, fittings, locking tabs, etc. that you need.
*Note that All Borg Warner Turbos listed are Journal Bearing only.
