so what you all ar saying is that the ssei doesn't have the plastic (prone to cracking) manifold? that means i am in good shape right? just looking out for my bonnie. i love her dearly! my parents must be getting that impression too. i've only had her for a week and whenever i need to drive somewhere, they tell me "you're just looking for an excuse to spend some more quality moments with your car"....what can i say? i just admit it

BADSSEi is running an intercooler on his Bonneville over at Intense and Thrasher makes a intercooler/Manifold for the Series II (but not the Series I The air cooler is mounted in front of the radiator at the bottom.

You are correct. No plastic Manifold for your '97 SSEi. The plastic couldn't take the added stress of your 240 hp beast. Too much air pressure, too much torque on the manifold from the supercharger belt, too much weight from your M90 Supercharger. You have an aluminum intake. But as I said before, a 180 T-stat will keep it cooler, giving you a more efficient charge from your SC. Have fun! You also have a wide variety of performance parts available to you. I would recommend the shift kit for your 4T65E-HD tranny and an Auxilary Trans Cooler (if you don't already have one). Later you may want the LSD. That should take care of your traction needs.

Next you could work on engine--exhaust, CAI, Chip, smaller pulley. Or you could go nuts--heads, rockers, even the block setup that the 200++ mph bonneville had. And to think that all this could be yours in return for a few thousand $$$$. You truely have a great car with a lot of potential. The only limit is $$$. Have fun.
