Advice requested on a supercharger for a 1990 Bonneville
Hi Y'all,
In a bit of a quandry. Worked on a lot of motors in my life, but no experience with blowers.
Got a fellow on eBay offering to sell an Eaton supercharger (the complete top end of the motor with all the fuel rails, TB, wiring, PCM, etc) along with the accessory brackets, pulleys, and balancer for $700
Here'* the ebay item number for the listing (before he offered up the brackets, pulleys, and balancer.) Item # 8063676537
Whacha all think?
Also curious about the interference problem one fellow doing his Reatta mentioned reguarding the oil filter mount and Power Steering pump. If it'* a big issue, is it possible to use the newer remote resevoir pump and different oil filter boss on the older motor?

Being that you're no stranger to full swaps, go that direction.
In the long run, the rest of your drivetrain will be very quickly beaten to death. Your rods are not as beefy as L67 rods, the wrist pin setup is different, even the rod caps if I recall.
Get the entire drivetrain. Motor, trans and subframe/mounts if you can. It'* been done here with excellent results.
The non-electronic 4T60 trans in your car will not hold up long.
Shipping from Hawaii is going to be rather spendy, and the question of WHO rebuilt the SC and WHAT was replaced should be answered by the seller at the very least. There are some very bad rebuilds out there.

So, you checked out my Reatta thread, eh?
$700 + shipping is a bit steep though. I picked up a good running L67 long block with 155k miles for $475 from a local salvage yard. Being complete is good cuz you have all the hardware and stuff. Beats having to go back to a junk yard to get little things.
I would rather have swapped in a complete L67 and 4T60-e/HD, but was cost prohibitive and would not work well with the Reatta'* electronics (touch screen Electronic Control Center). Ryan of GMtuners did the reprogramming of my stock ECM. I did not need wiring from the donor car nor the ECM/PCM. Only thing I had to do was extend the IAC harness like 4 inches.
It looks to me like you could swap the oil filter mount/assembly, but isn't really needed. We notched out the tensioner assembly because what I think is the oil pressure sensor was barely hitting it. Yes, you can add some hose and use the donor car'* power steering resevoir. Mine'* cobbled up for now until I get a chance to mess with it. I'm not using the stock air filter box anymore, so I think I'll mount the resevoir over where that used to be.
Feel free to post back or PM me with any other questions

First off, Looking at the auction, find out the year that SC is off (92-93 or 94-95).
Second, that looks like a Park Ave Ultra PCM. I got the bonneville one next to me from a 93. Only 2 plugs.
Third, I picked up a 93 SC, TB, fuel rail, injectors and cover for $150. It needed a coupler. There are two more in my area that I could get for around the same price (one in the same yard, one in another) I didn't cut wiring, or have the LIM cause I already have that.
That being said, I would go with a Series 2 swap. It has been done in a 1990 Bonneville already and there are two people on here with a lot of knowledge on it. You'll also have more HP than just swapping the SC on, and you'll hav more mods available later on.
