IMO waste of $, unless you are going to use it to spray the car.
Try to find a HVIII, real gains of about 20hp. some good starting mods would be:
-FWI/CAI
-HVIII
-L26 UIM & LIM w/ "green gaskets"
-powerlog
-Downpipe
-180* t-stat

if you want to go further than that grab some 1.9 Roller Rockers or a cam

dont forget a pcm tune too!

High Velocity Intake Insert

HVII -orig, HVIII - Improved

Quote:

The High Velocity Upper Intake Manifold Insert replaces the factory plastic runners in the upper intake manifold found in FWD Series II 3800's. Simply remove the upper intake (leaving the throttle body attached), pull out the stock runners, set the HV insert in the intake and bolt it back down
More torque - The HP gains of the old HV2 were quite amazing. The only issue was a loss in low end power. This meant that only highly modified setups could take full advantage of the high rpm gains. The new HV3 has slighty longer runners to give more HP and torque in all usable rpms!

Easier install - The new HV3 doesn't require special length bolts, RTV or any modifying of your factory setup. It sits entirely inside of the factory upper intake. It can be installed in less than 30 minutes.

More reliable - The HV3 does not require RTV, cannot be seen by anyone looking at your external engine, and it comes with a new intake gasket. Installing the new HV3 actually improves the reliablity of your car by replacing a potentially worn out gasket. Because it sits entirely inside the intake, there are zero sealing issues.

does not work w/ the L26 UIM/LIM, so it's an either/or issue

My friends swears that the same top swap or style of top swap would work on my car, that and there is a thing on zzperformance about the conversion. Any input on whats easiest and best?
