Where can I buy a 4.2 inline 6?

Quite honestly, I'm just sick and tired of all these Paul Walker wannabes running around in rice burners with exhaust tips and window stickers. Why, in God's name, do they think a Honda Civic or whatever other trash they may be driving is so hot?

I own a 95 Buick Riviera with the supercharged 3800 V6, but I'm not really sure that I want to make it a car for racing. So, what I'm thinking is this.

If I can get ahold of one, I'd like to purchase a 4.2 liter inline 6 from the new Trailblazer (prefer to buy crate, not entire SUV) and transplant it into a light(er) car, add some nice suspension for cornering purposes and start making those Jap "sports cars" look like grandma's 74 Ford LTD.

Can somebody, please help me find a place to purchase the 4.2? If so, do you know if there are superchargers available? If a no go on the supercharger, would it be possible to throw twin turbo to the 4.2?

Thanks in advance.

Oh yeah, and if anyone has any suggestions on what vehicle to transplant this 4.2 I6 would be appreciated.

I believe you want this forum.

Thanks for the direction. This is going to be a long journey, but I believe it will be worth it in the end.

Should be, but remember, the 4.2L won't easily fit in a small car. It is quite a long engine.
