SUPER CHARGER FOR A MONTE

[roscoepcoaltrain]

I have a chance to pick up a supercharger from a Buick Riviara... I need to Know what All I need to pull from the car.. I am going to grab the intake from it but what else do I need to get?

...the rest of the motor? And do you have a 4T65-E HD trans to back it?

If you have a 3800S2 already, you still need the whole motor from the donor car. The block for the L67 is still beefed up internally from what I hear compared to the stock 3800. Plus wiring the PCM is needed. So just "bolting the intake/supercharger up" to your 3800 won't necessarily work.

 

And you need the 4t65e-HD also to back the added power.

Deja vu...

There really is no differance from a L27 than a L67 as far as compression. But the whole front of the motor is differant. The only thing that is the same is the Water Pump.

So ok I can take the whole motor What would a fair price be It runs... (the car was hit on pass side)... Where would the wiring for the PCM br located is this the computre under the dash? or am I just stupid???? Also if Anybody is looking for parts off of it or wants my old engine let me know....

I belive the ECM is under the dash in a Riviera. What year is it? The price of it depends on whether it's a Series I or II.

We need to know a few crutial things here:

 

What year is your car? What year is the riviera?

 

Assuming they are both series II cars, you will need: heads, intake, supercharger, throttle body, fuel rails, injectors, harmonic balancer and all of the supercharger belt idlers, you'll also need a custom PCM since your car has different gears than the supercharged ones so you can't just use the PCM from the supercharged car, plus you'll have a full point of compression more so you'll have to run probably a bigger pulley than what is already on the blower.

 

You also would only have the 4t65e not the 4t65e-hd, so you will have a weaker diff. This won't be a problem with stock L36 + M90 power levels, but once you get into mods, say bye to the tranny.

 

But other than those issues, its pretty much a direct swap.

OK so if I can get the Engine and trans and pcm from the donor car what other modifications would I need to make to My monte for the new drivetrain if any? the miles on the car I have not heard about yet waiting on e-mail response.
