Well, I just took the time to go through the ZZp info provided on their site as to what items are really needed to do this swap, along with the costs as defined on ZZP.
Here'* what I found (don't jump all over me if I missed something as this was a few minutes of reading, not a research project, OK?):
$600 - Modified Gen III M90 SS Blower
$200 - SS Install Kit
$360 - SS Fuel Rails
$175 - SS Modified LIM
$ 35 - LIM Gasket
$120 - Pulley System mod kit
$ 25 - New Serpentine Belt
$ 10 - PCM Programing Upcharge (handling related, I believe)
$100 - 50 - Estimated miscellaneous parts and pieces and shipping charges.
$1,625 - Estimated total parts cost for upgrade
BTW, ZZP states 60 HP improvement, and claim that the HP alone will not make your 4T60E trans fail. I can't really argue with the basic idea behind that.
It is certainly an interesting approach, as we all know that the L36 has higher compression and therefore higher boost potential.
Is it the least expensive way to go? No.
Is it the lowest risk way to go? Probably not.
Does it have a legitimate place in the market? Most certainly.
Note that it has not yet been tested on a Bonneville.
