i found a series 1 supercharged engine for my bonnie for 300 dollars my question is would it be better to change out the whole motor or just the "top" stuff (ie heads, manifold, intake and supercharger, etc.) i will tell u that to swap the whole motor it will be around $1600 and im trying to save a little bit of cash.
p.*. the motor is good but the car was wrecked.
any help or ideas would be apreciated thanks

I'm confused.

You found a motor for your car.. ... why do you need a motor?
You wonder about swapping just heads etc..... what is wrong with your motor?

A bonneville is an easy motor swap. Recently Zuper8 swapped a motor on a 92, herself. Yes.. 21 year old woman swapped a motor. At $1600 you should shop around for a better price. If you were local to me, I'd do it for umder $500

First question is, are you already */C'd? If not, you need more parts other than just a */C'd engine. And to just to do a top swap, your gonna need a PCM, wiring, and to be on the safer side, transmission, drive shafts, fuel pump etc. etc.

no im not already */c but the motor im looking at comes with the trans. and sorry for the confusion, my motor is fine i just want to have a supercharged motor. also the motor im looking at has all of the accesories on already. hope this clears things up

Complete engine and trans? Lucky dog!

While its out, do a complete gasket swap from head to toe. And whatever Boosty recommends as far as fixes that NEED to be done prior to install.

Get your hands on those 4T65-E driveshafts, wiring harness, PCM, PCM harness and fuel pump.

ok i will do what he says but unfortunately i dont think he has the driveshafts any more but i will ask. could u give me a list of every thing i need to ask for

PCM
Main engine wiring harness
Fuel pump.
driveshafts
And the transmission wiring harness I believe. Bill Boost should pop in here soon and tell you anything else I may have missed.

Those are the main things. If you have to wait on the drive shafts, thats fine. Use the time now to strip the engine down and have a go at it.

Actually in 92 it'* probably a real pain. But you can probably operate the boost control actuator off vacuum and not use wiring to it.

On the pcm, all you need is the Eprom aka blue chip in the pcm.

Driveshafts..this is a 4T60 trans. If the 60 is like the 65, then you'll only need a different passenger axle, I'm not sure though.

I'd swap the whole mess. It'* less work to take the whole drivetrain out and drop in a whole one.

ok thanks on the list. on the pcm could i get an aftermarket performance chip and still get the same effect or would i still need to get the Eprom chip

You could have it re-programmed. I think.

I was snooping around Intense'* site today, and they only reprogram 97 and up. So, I'm not sure about your year. Boosty might have an idea.

To be honest, I would worry about getting everything in, tested and put a few hundred miles on it. Do your homework, then mod the snot out of it.
