I'm looking to buy an S2k soon, and I plan on modding it by adding either a SC or a turbo (along with the other appropriate mods).

Based off of cost, straight line speed, and which one will be more reliable and put less strain on my engine, which one should I go with?

 

where's a good ol' dead horse when you need one...

 

you should buy a corvette instead

 

You should read this:

That should be almost all the insight you need to make a decision. Also check around with local S2Ks in your area.

Good luck!
