When i get everything swapped over will i have to get my pcm upgraded right away or will it be drivable with stock n/a settings?

I don't suggest it. You will have different sized injectors, MAF, and throttle body. If you have access to a local tuner, I suggest using him. If you don't, you can ship me your PCM and I will give you a base tune so the car is drivable. You will still need to get a scan. I can get you set up for $125. PM me if interested, will need your cars information, year, make, etc.

Edit. Just noticed, is this a 95? If so, I can't tune that. Sorry. 97+

How would i find someone who could tune 95? or could i swap it with a ssei from another year?

The only one I know of are these guys. http://www.gmtuners.com/

And i keep seeing people talking about knock retard, i understand what it is but i dont have a scanner or anything to check fuel pressure. It worries me that ifi put this on ill blow the engine, i do plan on using 93 and if the forum approves octane booster. but i don know what else ill need to do.

Contact those guys and see what they say. Octane booster is a waste of money. It won't add enough to make any difference.

The pullies and belts will be a piece of cake with the engine in the car. We have so much more room than most of the other cars. I love the Bonneville for that reason.

The one thing that you may not know is the torque axis bracket/spacers are different from SC to NA. Make sure you have the right bracket for the engine side (body side is all the same) or your bracket will hit and bend the pulley.

Yeah..I bent one.

I dont know what bracket that is

Would i be able to just swap my pcm with that of a ssei of the same year? or just go to obd2?
