Hey,

I'm new to these forums but not to the world of automobiles, I am wanting to turbocharge my 05 3.7L Jeep Liberty, for the purpose of more horses and to make it sound awesome! Any idea's if the 2.8L turbo would bolt on to the 3.7L without any issues?

There is a major problem with the 3.7 V-6(same goes for the 4.7 V-8) when force fed,the top piston rings are located to high and the added PSI can break those piston releasing the top piston rings,bye-bye engine.Kenne-bell tried a super charger set-up at only 5psi and blew the engine and then they axed the kits for the 3.7 V-6's.You'd need to tear the engine apart and get forged pistons put in and major headwork done.Looking at about $3000(parts alone) alone to just get the engine ready to take the added HP from a turbo or supercharger.Not to mention it would be a piping nightmare to add a turbo to the 3.7 V-6 in a KJ.

The KJ is a Jeep,not a sports car,it's got plenty of power for what it is made for.You want to race get something ment to race,not a SUV.Don't add fuel to the fire by rolling your KJ in a street race,the greenies are trying to ban SUV's already and they don't need more free press supporting them.

You want a better sound add a FlowMaster 40 or super 44 muffler,JBA makes header for the 3.7 for '03+ KJ's also,add a CAI and you'll get about 20-30HP more.

Personally I just wondered if it was possible, since it isn't I will just stop at that, but I do have one question considering this isn't a 4x4 and I don't really prefer to go offroading in the jeep. No 1. I have a suspension issue and it is like your riding with Teddy Roosevelt and the "ROUGH RIDER" gang lol, what type of shocks/struts should I choose because I have heard alot of things about KYB and other brands and no 2. I want to do something to make it look nice and I was considering putting chrome on the door handles and maybe upgrading the rims.
