Me and a friend are gonna turbocharge his 1993 jeep wrangler... Its got the 2.5L 4 cylindar engine... Were thinking of a reliable low boost system to add a little more pep to the car, but we need some suggestions on how to do this!
I know most of the basics but any suggestions would be great!
Thanks
someone came through here a while back with a basic turbo 2.5 wrangler and ran 14.9 with it.. thats a lot of pep for a 4 cylinder wrangler..
his username was turbojeep or trrbojeep or something along those lines.. try the search function and see if something comes up.
how similar is that 2.5 to the one in a 90?
my friend has a 2.5 jeep too and we hate how slow that thing is
It should be the same engine. I believe they were all the same even into the new body style for the most part with only minor changes.
yeah i was looking at it
it all seems the same
if it was mine i would do an easy T1 swap
Plenty of options. Not hard to push 250hp and actually increase your fuel mileage!
If it was me I would swap in a 4BT cummins turbo diesel!!!! Then run it off of veggie oil. Nothing like extremely cheap fuel and a ballsy Jeep to make things better.
haah that would be sweet but i know nothing about diesel that would be the biggest mess and the longest project if i did that
That is the best part. The 4BT is practically stand alone as is. For 2500 usually it better be;)
The cummins 4BT would be awesome but were a couple of mechanically inclined high school kids... The jeep with 33" tires is just slow as hell and it needs a major power boost!
We were thinking of fabbing a crossover pipe off of the end of the header to bring the turbo back to the right side of the engine bay then running the exhaust through the fender (LOUD AS HELL!) and then plumbing in a decent intercooler!
For fuel we were thinking of getting a slightly larger injector and lowering the fuel pressure and then using a rising rate regulator to increase the pressure as boost increases providing enough fuel... We might throw in some meth/water injection for added safety...
Im pretty sure 10PSI would be doable with 93 octane and some meth injection...
Thoughts?
are you sure its not port injection? i didnt think tbi went as far as 93 on that motor.
The piping setup sounds exactly like what everyone else does on 2.5/4.0 so you're on the right track. Exhaust out the fender wont leave room for a muffler and will probably get old fast. Leave yourself some options before you decide to cut it up....
Yea its multi port injection, I checked it out tonight!
what tranny? Might not want to add too much hp.
For the amount of power I am predicting on this one trans should be fine as long as it hasn't been beat on and has had a few fluid changes in its life. Sounds like a really cool idea on the turbo setup. Wish I could picture a Jeep engine bay. Its been a while.
Bumpity
Find a 91-95 Xj with a 4.0l auto and swap the drive-train and harness in
I have done this swap 4 times now the owners never regretted it
once you have 4.0l in and running then turbo it !!
