You might want to avoid Mr. Turbo kits from all I have heard. If you just want low boost and an affordable 200+ HP, get the Hahn kit. If drag racing and top end stuff is your flavor, go with an MC Express kit. With a properly installed and tuned kit, the life and reliabilty will be the same or greater. Remember that the engine itself will now be running a lower compression (usually 8:1, if I remember correctly).
