I'll go downstairs right now and grab an M62. One moment please.

EDIT: It should be really easy to weld these. The openings are so tiny compared to the M90.

nicely done, and thoughts on porting one? just smooth the rough spots on the main outlet hole or could one increase the size to allow more air flow, or is it at is peak on performance?

EDIT: Porting the Inlet not in question, that could be increased to match a bigger TB to allow more air INTO the SC, but flowing out is what im curious on
thanks

Supposing that you will drop the pulley size, you are going to increase the flow of the supercharger. Increasing the outlet hole size helps here. A smaller pulley is like opening up the **** on your garden hose. Well, almost. After one point, opening up the water flow on the hose doesn't get you any greater flow at the hose end. Then you need to get a bigger hose. It'* too basic, but it'* generally how I see the supercharger outlet - as the end of the hose. Port away!

Take out those two humps by the base of the triangle, and then port out just a wee bit. Make the triangle taller. You probably are going to have to cut into the bar past the top of the triangular opening. No biggie. Also make sure your LIM opening matches the length of the triangle. But from looking at this tiny supercharger and thinking about the lack of aftermarket Series 1 parts, I can't help but ask if you could go up to the Series 2? It is cheaper to upgrade and can get you a faster car for less money.

putting in a whole new series 2 sc MOTOR wouldnt be too hard to upgrade and ive thought about doing that swap, but the m90 wont bolt onto the intakes, and you cant do a series 2 intake swap on a series 1, nor a full top swap with the heads and all... the series 1 cyls are not in sync, theres a gap between 2 cyls on both sides unlike the series 2 motors... so its completely different and uncompatible... darn it lol

on the down side id like to drop a S2 motor but want to keep the original motor in it

thanks for the info... id like to have her apart this summer and port and polish the SC, UIM, and Heads hehe make em silky smooth HAHAHA

Wait... I meant the whole Series 2 L67, not just a top end or an M90. The Series 1 has been proven over and over again to be a slow engine. The quickest Series 1 L67 daily driver is in the low 14s, and he'* invested tens of thousands of dollars into all sorts of stuff. With an intercooler, the smallest pulley ever used on an M62, ported & polished everything including heads, he'* only in the low 14s. That'* what you can do with a stock Series 2 L67 with an intake, high flow cat, a tune, and a smaller pulley. A stock Series 2 L67 is about $300, give or take a hundred, and you don't even have to take it apart to polish it! Just throw in a stock engine, put on a smaller pulley, intake, ported exhaust manifolds and a 2.5" or 3" downpipe, you already have no cat, and you should be in the low 14s. How much time do you have to invest to do the same thing as the only and very single 1993 SSEi with a Series 1 L67 to get to where you can be with $500 and no true work aside from an engine swap?

Also, you're probably not considering the transmission. The 4T60E-HD is what you have right now, and the 96 SSEi came with that as well. After that, all the supercharged Bonnevilles got the 4T65E-HD transmission. It'* a lot cheaper to build up, and it'* insanely tougher. Let'* go back to the quickest Series 1 L67 of which we know, aside from the one guy who threw on NOS and ran a 13. That Bonneville is on its third or so transmission, and the owner is experimenting with a differential of unkown strength. He took a few days to install this thing which is stronger in stock form on a 4T65E-HD, and no one is sure if it will last. How much money after all your work on your current engine do you have to invest to keep rebuilding a transmission that breaks?

Ultimately, you can get a used Series 2 L67 and 4T65E-HD for less than a grand, put on a couple hundred dollars of bolt-on mods without taking apart anything at all, and beat the crap out of the quickest Series 1 L67 Bonneville that keeps breaking transmissions and various engine parts. This is the best way to go as the aftermarket supplies for the S2 engines are almost too plentiful. Everyone mods the S2, but the S1 is left out and not attended to. Everyone mods the 4T65E, but the 4T60E is all alone in stock form with very few parts & pieces to upgrade it. The real differences between your 94 and a Series 2 are the engine, transmission and some parts leading to the wheels, wiring harness, and PCM. Swap over these things, and you've basically upgraded to a much more powerful engine with a ton more potential.

Ya that would be a better solution but i cant find a L67 with a tranny around HERE for less that 2 grand because its a supercharged motor with tranny and both work lol... oklahomans and texans are kinda funny with stuff that works... haha

what "parts to the wheels" would we be talking about having to change??? shafts, brakes, abs sensors? everything else i could prolly get... heck if i got a trailer i could prolly just pick up a whole car for parts cheap enough... but it finding one... i know of 3 in my area that dont run and are rusting over but the people wont sell them because theyre hard to find and they dont want to sell it for cheap

As I'm aware, the steering knuckles have been the same for at least 92-99, maybe longer. That lets you keep the entire suspension including brakes. The ABS setup may not work on the swap or it may, but changing the ABS sensor itself doesn't affect the wiring. Supposing that the ABS is retained, turn it off anyway because leaving it enabled cuts back your timing and even shuts off the fuel injectors when the wheels break loose. This is bad because you can chip a piston simply because you don't have traction. Kind of odd... The parts to the wheels would be the transmission output shafts, and those reach through the steering knuckles into the bearings. The bearings are the same, so you can keep even that.

Buying a Series 2 Bonneville would be cool. And if it really works, you could even drive it over to your house. Good luck! See if there are any Park Avenues, Regals, 88s, 98s, or Grand Prixs with the L67 for sale.

Actually, I don't have a basement. My PC is upstairs, and the ground floor is connected to my garage. There are some M62s and M90s in my garage, as well as a few other things, because I either am fixing them up or am planning to use them on my 94.

But if I had a basement, it would be filled with M62s. Don't know why.
