F20 or F22?

They're pretty much boost ready from the factory. Improve cooling.... radiator and oil cooler, go drive.

I need to know the same thing... I have an F22c with 164000 miles on it and I'm wanting to boost it. The power is outdated compared to other vehicles that are on the market. I just want it updated so that it will last another 200000 thousand miles but with boost.

Have you seen the Ptuning Kits which are selling here? There's a group buy, that paired up with a Garrett GTX3076R would turn your 250hp into 500hp.
I have the Sheepy Kit with the above turbo and I absolutely love my car now.

Ptuning had a recent response that they might not make their s2k kit anymore. That will be too bad for the s2k community if that's the case. I love my s2k now too more than ever.

They're not officially discontinued. If we have enough people still interested in kits, we will consider making another batch. @soulicious Just saw your dyno graph with the GTX3076.. Good to see 600+WHP s2000's with our kit.

600whp with a GTX3076? Got to love the USA dyno's. Massively exagerated-roughly 20% high

Mate, that's with a GTX-3076 Gen 2 on E85 at 23psi. Stock puts down 200whp on the same dyno which happens to be a DynoJet. You must be thinking of Church's Dynapak. Regardless, it's the delta that matters.

Yes identical Turbo to mine & E85. At 21psi I hit 410hp here in Australia on a Hub Dyno.
Typically US dyo's read 20% higher. Have absolutely no idea why.

Not sure, but it sounds like your tuner and/or setup sucks buddy. You roughly should have at least 15whp per psi.

My setup and tuner is solid.
