Ok guys im a noob to this forum so if im mistaken in any info just help me out... Ive got a 98 jeep cherokee 4.0 L6 and i want put a turbo ofcourse..

i have a big 16g turbo EvoIII w/ adjustable internal wastegate. dont remember much of the specs, it been with me for about two years and not been used after i got rid of my eclipse..i need info on what the best management systems i should use, what size injectors.. etc.. also goin to have a FMIC installed behind the radiator. took out clutch fan and aux so have plenty of room. put two electric fans in front as a pusher...

if this turbo doesnt work with the application im going to just get a T3/T4 but bigger is better. I'm up for all answers and suggestions im in this all the way even if its a slow process....

so your going to blow hot air radiating of your radiator into your intercooler? does sound very efficient to me

yea, you should probably put the inter-cooler in front. And when the hell did the 16g start being classified as "big". Its in the "tiny" category for me.

turbof22a

well there is a 16g and a big16g thats why he said he has a big 16g

ah i see.

Still not a big turbo lol, but i get where the name comes from

well there was only two places i could realy mount it either ther or on the top of the engine and put a hood scoop but either way im still getting 50/50 cold and hot.. i would mount it directly under the radiator but i dont want it to be seen its goin to be a sleeper... im not a trail rider i want horsepower... anyways would this thing work im looking at i and i think i would have to mount it upside down since its not a top mount and the down pipe i have would be cummin up.... or fab up a new one... so give it to me what the hell should i do.?

And yea there to classes even though i dont know much the different but this is a big 16g.. and i think its big enough for my app.

I realize the 4.0L Inline 6 from Jeep is pretty inefficient when it comes to breathing and revving, but lets do a simple break down of displacement vs. turbo sizing.

Stock eclipse engine - 2.0L with a half way decent breathing DOHC head.

Stock jeep motor - 4.0L with an obsolete head that dates back to the 1960's.

I think you need a little more turbo to get started, I'm not saying it won't work, just that your manifold will be glowing at cruising speeds because you will have her backed up with a small turbo. If you did do this it would make great torque, just not much more power and would probably fall on it's face up top big big time.

A turbo jeep with a 4.0L used to hang around the drag strip near Pittsburgh and the owner ran a 60-1 with a stage 5 turbine wheel. That is almost double the size of a Big16G It ran 12's and was reliable to the best of my knowledge.

Ok makes sense... Can you give me a couple i names i should look at cuz im trying to keep away from any nokoffs.. ive been looking at some garrett and turbonetics.. but the price range is a lil out of reach... when it comes to everything else i think ill be pretty set even though the management system might be a lil tricky... im not to good when it comes to the electrical part.. i know the basics..

And thank for everyones input... keep it comin.

Disregard the prince range on those im sure i can handle it...

Most of us guys here on HMT run Holeset turbo's from Cummins diesel trucks.

You can run the stock turbine housing from a Cummins if you like or try to source a smaller one that fits which I never had much luck at. I have always gotten turbine housings like these to help me out.

1. Find a good condition HX35 or HX40 from a junkyard, ebay, craigslist, etc.
2. Get this turbine housing cut for the appropriate turbine wheel.
Tim's Turbos - Turbo Rebuilding - Steel Turbine Housing - T3 Inlet
3. Rock out with your **** out for less then $400 bucks if you get lucky.

Holeset HX35's and and HX40's can also be rebuilt on the cheap as long as the compressor wheel or turbine wheel don't get blasted and the turbo shaft doesn't get scored.

ok what would i be looking at when it comes to how much boost i can run on the stock internals as well as what do u think the spooling rate would be.. dont mind the slight turbo talk dont know the specifics about these things..
