Which companies make turbo kits for S54's? I specifically am looking for a turbo kit not a supercharger. It is for an S54 Z3 M Coupe.

Thanks

Horsepower freaks is the only one right now. It's $16,000 US. A/A might come out with one soon..

wow, 16g usd... What does it come with? I couldn't find any info on a "kit" on their website.

I was hoping to aim for 7-8G USD Max.

Not going to find anything for that price (supercharged used maybe.. never turbo). You want *reliable* HP, you'll need to pay for it. For $7g you might be able to get a "home-made" turbo kit running low boost on the stock ECU. $16k for 700hp is still a bargain when you consider what other cars out there can keep up.

For the amount of R&D they're putting into this kit, 7-8G USD is out of the question. The kit isn't quite complete yet as they're still doing some more testing.

Even Active Autowerks' Rotrex S/C for the E46 M3 will cost you $8-9Gs USD. VF Engineering's Vortech S/C runs $10,000 USD for stage I.

And that's for stageI... for the record, I know someone who's selling their AA StageII+ kit for $8500.00 (used 5 mths - $13,000 value) puts down around 510HP crank. Consider that Manimillion and PM me.

Is it 700hp for 16g's thought? If it is, yes I would be willing to pay, but if its just a turbo kit running on 8psi no I wouldn't want to pay.

So I assume it comes with internals as well?

stock internals (yes, I know) and stock exhaust with race gas, T67 turbo at 13.5psi = 667rwhp. They've done over 100 dyno pulls at over 600wHP and the stock motor still shows no sign of giving out. Don't know how effective big HP number cars like this are without driving on slicks 24/7... as soon as you hit boost, you break traction... even in 4th gear. I'd recommend going with a used AA stage2+ kit for half the price. Much more usable power band with smooth torque delivery instead of these high-powered dyno queens.
