V6 LS1 Killer?  It's possible.

With a power increase of up to 80% that anemic 193 horsepower motor can now make as much as 350hp on a Stage II intercooled system for 1999-03 mustang V6.  This system features a P-1SC head unit and 2 core intercooler.  At 9-11 psi you will see an increase of 50-80% in horsepower.  The HO system will make a power increase of 40-55% at  5-7 psi.  If that 5.0 or Mod motor swap is out of the question and you want to pick up some ponies this is the answer for you.  For polished head unit add $250.  For 3 core intercooler add $345.  On 94-98 systems add $88 for Omit FMU and $98 for Omit fuel pump.  These kits use the stock 6 rib drive system.

These kits come with a 12 month warranty and usually have an optional 3 year warranty for $49.  Some race kits only have a limited warranty.  The 96-98  kit is 50 state legal (EO D-365-6) 99+ kits are pending.

A tuner kit, which excludes the fuel injectors, fuel system and computer tuning, is also available, and is otherwise identical to the HO Intercooled system.
