this was copeyed and pasted from another forum
I thought the attached pictures might be of interest to many of you. They are of the Eaton supercharger (from a 3.3L V6 Nissan Xterra) that I mounted on my Frontier KA24DE engine with 240SX upper intake. Notice how well it fits in place of the original 240SX plenum. The blower case itself of the Eaton supercharger already has an internal plenum built into it, so all that is required to fit it up to the 240SX upper manifold is a ½†thick flat plate made of aluminum (If you look closely in the pictures I used a ½†sheet of oak plywood to make an initial pattern for fit up of the supercharger which I will then lay over the ½†aluminum plate in order to cut & drill it correctly). The blower case just clears the alternator by ¼†and on the other end just clears the starter by about ½â€, and then it just clears the smaller Frontier type oil filter by only 1/32†so it is a very tight installation but does work (I might change out to a remote oil filter arrangement in order to make it a little easier to change the oil filter when required). Note that I have replaced the original power steering pump V-belt type drive pulley with a 6 groove serpentine type as well as the adjustable tensioner idler pulley with a 6 groove type as well (the power steering pulley is from off a Nissan Altima, and the idler pulley is off an ’01 3.8L V6 Ford Aerostar of all things…both fit perfectly!). I had a custom crank dampener 6 groove drive pulley made that bolts in place of the original V-belt pulley for a Hardbody KA24E type dampener, so that is what I used on the DE engine (it turns out that it all fits on the DE crank perfectly and even weighs exactly the same as the Frontier’s one piece crank dampener…also, they are both neutral balanced so they are interchangeable). The only thing that I haven’t completed on the drive system is the two ¼†steel plate brackets to support two smooth idler pulleys (from a ’98 GM 3.8L V6) that are required to get the 6 groove serpentine drive belt to wrap around more of the circumference of the supercharger & crank pulleys for greater surface area contact so the belt won’t slip while driving the blower & power steering pump. I have the upper idler pulley support plate cut out to size but still have to drill the mounting holes (it will replace the original Frontier front brace plate). The lower idler pulley support plate will be a bit more difficult to make since it has to be made to also double for support of the alternator since there are no good bosses to support the idler pulley off of other than a few mounting bolt points on the timing cover and the alternator mount points (I have it all figured out on what to make, I just haven’t gotten to the point of actually making it…it just requires so damn much time to get it all figured out!!!)
More to come when I finish the remaining items!
