I've got a '01 S with 79000 miles on it. How much money would it take to get to 400RWHP?

 

A LOT.

 

depends..do you want it with a supercharger or a turbocharger?

 

Whichever is cheaper.

 

if you going turbo, you are looking around 7k to 9k depending on the turbo kit you get and the tunner.

 

Plan on 10k. Hands down.

kit,
parts,
guages,
AEM,
tune,
clutch,
injectors,
LABOR, thats fun.

 

quick quote

Turbo kit: 5 - 7k depending on the kit
AEM EMS: $1000 used $1300 new
fuel pump: $100 ( some kits don't come with it)
Injector 750cc + clips $400
Tune: $800 - $1000 depending on the tunner
Install: 700 - 900
clutch: 700 - 900 ( many option here)
Gaugues: if you get te nice one's ( defi ) $240 each + controller unit.
AEm fuel regulator pump: $170

Maybe a 3" exhuast ?

Raven628: he is righ more like 10K +

Note: have a least $700 extra because alot of little crap will come up...

 

Assuming all brand new parts + labor, you are looking at 10K+

But it's sooooo worth it.

 

Will you guys be pissed when i do it for under 4000?

 

No.......But if you're using used or junk parts it will cost you in the end with major problems. If you're fabbing it up yourself, it's not proven and you never know how it will turn out and you may have to start all over.

Good luck!
