Going to be doing some headwork in the next few months for the winter, ship it out probably and looking at AMS's port work and their intake manifold but while at work I was bored and browsing some places and spotted this on Lancershop.com. People enjoyed their Engine Torque Dampner which is totally different but just curious:
Weapon R

 

if they can guarantee atleast 30 hp to the wheels then maybe

 

i have heard bad things about weapon r in general. couldnt say from personal experience though....

 

i don't think anyone has used that on an evo! You could be the first....and i CERTAINLY woulnd't by it based on a 30hp guarantee (doesn't mean much to me) - heck you can supercharge any car for 69.95 lol. my .02

 

I don't know why Weapon-R gets a bad rap. They have good customer service. Some of the stuff they have is "rice", but I love my torque damper.

I would guess this is a fairly decent piece, but the AMS VSR is very close to the same price. The VSR has proven itself, the Weapon-R manifold just needs some install time on a few cars.

 

I wouldn't mind putting the AMS intake manifold on my car.
