ok i keep reading about option b now is this a kit you can buy or wat? and also wat parts are involved and how hard is it to setup? and please no flaming if you dont have any helpful imput dont bother posting thx guys

 

I'm interested in knowing the same thing. I can't find the kit anywhere.

 

crate engine depot sells the kit, its very easy to install once you have the dual, pass end plate on

 

option b is not a kit per se, it is one way you can install the dual pass endplate from GM. Crate Engine Depot does sell an "option b kit", but all it really is, is the extra parts you need to install the endplate in the style of option b. Read the instructions on the crateenginedepot.com site:

wow that helps alot its just way to blurry on my phone lol

 

the hardest part of the install is popping out the laminova tubes and switching them. Not that it is that hard, but its tricky. THe inlet manifold(Laminova intergrated into this) is held by bolts and studs, which you can see and a gtricky bolt underneath that you cannot (15 mm head on bolt) There is a an external torx socket that can undo and remove the two inlet manifold studs (use blue locktite when replacing them) this you can release the inlet manifold assembly up and out without too much drama, then once you have the manifold out you can swap out the laminova cores (tubes) and install your new face plate.


When removing the supercharger, you need to relax the tensioner to remove the belt (15 mm open end to push back and down on tensioner) pop belt off. Remember on re install to line up belt in all the grooves if it is off one on any pulley belt will squeak.

Before removing the supercharger,remove the connector on the throttle body (underneath the s/c) make sure you pop off the grey forked lock for the connector, use a small screw driver to depress the center lock and then withdraw the connector carefully dont pull on the wires pull on the connector. Fiddly PITA job.

The instructions for the dual pass should have the torque specs for the inlet manifold (22 ft lbs) and the tightening sequence, and the s/c (use a 6 mm allen key, get the 6 inch long extended 3/8 drive allen otherwise using a short allen key, the top left bolt will require you to remove the fuel rail and you dont want the extra work; using a normal non 3/8 drive allen key will not permit you to torque the bolt afterwards. Work should be done with motor cold (doesnt have to be stone cold) and all bolts should be torqued to spec.
This is not the full story but all I can spare the time to write right now Best of luck

Torx external E8 required for stud removal.
