3.1 Rebuild


Omega-Red

Recommended Posts

Ok guys so I finally decided to take apart my 3.1 and replace all the gaskets and get it bored maybe and so on. I have a few questions towards this.

 

1. There are so many wires in the engine bay that it makes me sick looking at all that crap. Why cant it be as simple as in V8 muscle car engine bay. What are the things I can easily get rid of without removing anything that's necessary to be there.

2. Where can I get gasket kit for all the gaskets replacement in the motor.

3. What is the original bore and stroke figures and what is the maximum figures I can put on the engine without sacrificing reliability.

4. Where can I possibly find factory turbo manifold of grand prix I believe.

5. How much PSI 3.1 can handle stock and tuned and if tuned what are the parts that must be replaced to cope with the new turbo setup. T04 hybrid most likely.

 

Thanks in advance to everyone.

Unless you carb it, and are suddenly able to ditch like half of the sensors, pretty much everything has to stay.

 

Trust me. It's not as bad as it seems. You'll get used to it. I'm tearing down the topend of a 3.1 for the 4th time tomorrow (save heads) and it's easy enough remembering where the wiring goes.

I believe it can't be bored beyond 3.2, but I don't know the exact mm.

I think you can go as high as .060 overbore each cylinder but .030 should be enough to get a nice surface for some new pistons. Like it was said the wiring is pretty simple once you start taking it all apart (trust me I know how annoying the rear of the engine is on the gen-2 with all the different brackets and wire/vacuum line routing) I remember looking at my 1st car when I was 16, the '90 olds w/ 3.1L, thinking "if I remove this black box what could possibly happen, what the hell could this do to an internal combustion engine?" well yeah that was the MAP sensor.....LOL
