im a jeeper and a hot roder so i want to turbo my 93 xj 4.0L H.O. just to see what it will do i already have my import buddys findin parts but will the motor be able to handle boost i have 180000 miles the motor still strong what is the compresstion and can i put the turbo off the header or by the muffler.What is the most boost i can push if so i know what i need to run a turbo but just dont know if its possiable to put on a jeep.not lookin for insane power just more dont want to chip or crap like that i made my own air intake and i can get it tuned just need to know if the motor will take it.I know about putin a 350 in but to much work and money

try this part of the forum (street Cherokee) http://www.jeepforum.com/forum/f97/

there are more members on that bord that have used Nos and such on their XJs to make them smoke tires

the most boost the I6 can handle is 18.334 PSI.

no but really talk to Bryson, he probably knows 10x as much as 99% of the members here about turbo'n an xj

u need to re-map the fuel and timing plus run larger injectors, or you will detonate, run lean and brake ring lands. i made my own kit for my car. and i can run 12 psi without detonation and i drive every day to work no problems. my friends think they can get away with the stock timing and fuel map. they blow up engines all the time. you have to put more fuel because you have more air! just pay the extra money so you don't have to replace your engine which is a pain! i have 170k miles on my engine!fyi you must get a wide band o2 sensor cause you don;t want to go below 11.5 to 1 under boost! there are alot of other methoods to get more fuel, but the best way is to use the factory computer with a tuned map for your application. other methoods are chancy at best. they might work for now,, but why take a chance?
