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 blanket, but still has all the clamps, fittings, locking tabs, etc. that you need.
*Note that All Borg Warner Turbos listed are Journal Bearing only.
S251sx - This turbo is rated at 47lbs/min and will make just shy of 450whp maxed out at 29psi in the .48 A/R turbine housing. Expect full boost around 3000rpm and most people see 340-360whp at 20psi when properly tuned with the correct supporting mods.
S256sx - The 56mm Extended Tip'd S200sx turbo is rated at 55lbs/min and will make around 510whp at 30psi in the .63 A/R turbine housing. Full boost can be seen around 3500rpm in the .63 A/R turbine housing. These turbos likely see 360-380whp at 20psi when properly tuned with the correct supporting mods.

This kit is very good. Came fast. Great fit. I would have gave it 5 stars but the o2 housing to turbo bolts were too short(wouldn’t fit through the flange) and the bolts at the downpipe were so poorly welded that they came right off in shipping.
Just wow!!! Loved installing this kit as much as I love how well it made the car run. Quality of the kit was above and beyond what I expected. Thanks AGP for keeping this kit alive and helping to bring smiles this way. You've got a loyal customer here!
I purchase my first big turbo upgrade. The installation was made easy by the instruction provided. there is a few things that need to watch for is your engine stud from your old manifold. don't use the bottom one. use the stud that is provided with the kit or your AGP manifold won't seated right. after installation my SRT-4 are screaming. love it.
The reason why i gave a 4 star, is because you need to buy an after market water overflow for your radiator, and is not part of the kit. overall the Turbo kick @#$!
Was a great install and made upgrades easy.
