Only thing that's missing from that equation is the neccesity to be a good welder, so add in the cost of a welder and welding supplies or to pay someone else to weld up the hotside and I think the cost differential becomes close to a wash.

Trust me, I considered going single turbo like KYTP's kit multiple times over and over.

And "subtract the hotside" doesn't count when you'd need a set of headers for a proper supercharger setup, which will run anywhere from $400-800. I can't say I've seen a complete used D1SC kit go for under $4000, which is a good deal more expensive than the numbers I ballparked.

It'll be expensive either way, and if you're like me, "budget" went out the window as deals or setup changes came along...but I believe it's a common misconception that it takes $6k+ to turbo a car.

I didn't take into account the headers and exhaust setp because at this stage most guys who consider going FI have already done all the bolt ons, and possibly a cam (or two)

for the cost of a 4k dollar D1 kit you can easily setup an A2A turbo setup with all new parts, with a ceiling of roughly 800hp. josh @ kytp offers a complete kit for under 4 grand, IIRC. you'll still need a fuel system and an engine that'll take the punishment, but i dont think ATI includes those either...


and to be honest, you cant really play that "most guys" game, because thats bs. "most guys" can also sell their headers/exhaust with a turbo setup, too.

Sure, I could space down the k-member an inch, but I'd still have to cut the cowl to get it to fit. Even then, it's the smaller mp112 that's being offered. So then with all that work, you top out at ~550 rwhp if you get everything optimized perfectly. 550rwhp is cake out of a P1SC much less a D1SC. There have been a few guys on here who've made over 750 rwhp with a D1SC on stock cubes.

Also, all that instant low end torque isn't worthwhile on the street unless your running slicks. So the way to be the fastest is to generate just enough horsepower to hit your traction threshold throughout the rpm range. As your speed increases, that traction threshold will increase, which is why having a more gradual increase in power is better than a sudden hit. Power is wasted if you spinning. Why do you think the turbo guys have programmable boost by gear? There's no way to hold 1000 horsepower in the lower gears.
