Turbo 2.5l YJ

[wrangler94kyle]

This might be stupid but I am thinking about putting a turbo on my jeep. I just need little more power out of my 4bangger .
I know they don't make turbo kits for the engine in my jeep but I am thinking about it anyway...I just
Wanted to see if anyone had done this or has any advice or anything to help me out in anyway ! It's greatly appreciated !

505 Performance makes a turbo kit for the 2.5. They did a writeup in JP magazine on putting one on their YJ.  November 2009 was the issue, here's their site http://www.jpmagazine.com/techarticles/engine/154_0911_505_performance_turbo_system_for_jeep_4_cylinder/index.html

I dunno if you've done gears and lockers yet but I'd probably suggest getting that done before putting a turbo on.

First off - having owned a 2.5L YJ with an automatic let me assure you - I understand your desire for a little more out of the engine -
There's a reason that turbo kits are expensive - a lot goes into a good one.  It's not just the turbo - you have to control the boost - in Saabs this is accomplished by what's  called the APC (automatic performance controller) - it detects pinging and adjusts the bypass valve to vent off some "boosted" air - which lowers the pressure and keeps your connecting rods from exiting through the oil pan or block.  You might also have to change your injectors - going to a higher GPH rating - you might have to monkey around with your fuel pressure - there's a lot involved.  As most engineers don't work for free a company that markets a turbo kit has to invest a load of money in developing and testing the product before sending it to market.  They also have to prove that the kits don't interfere with emissions controlls and pay liability insurance so when some clot blows up his engine they're covered.
For general off-road work supercharger (belt driven compressor) would probably be better than a turbo - which depends on exhaust veloicty to drive the turbines and compress air because your exhaust velocity will be rather low (not boosting) when you're crawling.

I agree with what was stated before - gearing and suspension first.
