Hi, I'm new to the Porsche forum and first off I'd like to say "hi" to everyone. My reason for this post is that I have had my 1997 993 Carrera for almost 3 years now, I am the second owner (not counting the dealer it was sold back to) and I have installed a few minor bolt-on parts onto the car. I have heard from numerous sources the most I will see staying naturally aspirated is 360whp and so my question to you guys is of all the twin turbo conversions out there, which offers ther best bang for your buck? I've seen Protomotive Engineering kits that supposedly get 800hp but at a cost of more than 50k. I've also seen TTP kits getting 600whp for just 25k by comparison. There are many other kits I have not named and I am sure there some I dont even know exsist but again, which twin turbo kit for the 993 offers the best bang for your buck? Thank you for any and all help. Have a great day!
