Hey guys, I am brand new on here, so I am sorry if there is already another build topic on this. But I want to turbo my '92 Lebaron 3.0 V6 Convt. I have a 2nd identical 3.0 out of a minivan that I am going to break down and rebuild for this project. I have a bunch of ideas on how I am going to go about this, but it is my first Mopar build, and its one nobody seems to have really done. There has been some research and speculation, and the failing of the Daytona IROC which would have had this set up. My biggest issue right now is I am hearing so many opinions on which turbo to use. I only want to push about 10lbs and have about 300bhp. I am not trying to fly around, just want it to be a quick little daily driver.

I got this car for free in trade, and just about everything done to it so far has been free or by trade as well. In total, I have had this car for a year and a half, and besides regular maintenance, I have less than $1000 in this car. It has over 200k on it, but I don't know how much because my ODO stopped. The engine is still running strong, but when it blows up, I would like to keep the car and have some fun with it. These are the ideas/plans/current mods I have for the vehicle. Will post pictures of all soon. Any help, advice, connections anybody can help with is greatly appreciated. Hope you guys like it!!

Ok, we have quite a few threads floating around on this so I'll cliff note this, check out the 3.0L turbo section.

300 hp shouldn't be a big deal, GT35R, HX35, HE351, 60 trim is all capable of that.

Do a stock rebuild with custom forged pistons from Venolia or piston manufacter of choice.

Intake mods to swap plenum around or custom.

Heads, just clean up and do a mild port job or leave alone.

I sell custom cams for the 3.0L and we offer headers which are probably the best out there-links to follow.

Bigger injectors and a remote 1:1 fuel pressure reg

255 fuel pump, Aeromotive or others over Walbro.

Custom cal by "www.boostbutton.com" and a aftermarket piggy back controller.

Forget the A604 for now, we are still trying to figure it out, so go 3 speed or 5 speed manual.

That's the bulk of it.
