Guys,
I think alot of people notice mediocre improvements with the 16 cm housings. The reason alot of folks run them ove rhte 14cm wastegate housings is because they're cheap (the housings, not the purchasers). The 14 is a little more expensive, but it is the way to go. The 14 cm houisngs on these trucks have great lowend performance, but if you have 4. 10 gears and are going to "high speed" the engine, the 16 is the way to go. Let meknow if you need either. I run the 14 and love them, I just changed my 99 to a 14 also. The 12 is too small for much power gains witohut heat. Please email me if you think you need a different housing.
thanks
Don
