The guy on Ebay who sells the turbo "E-book" is making me a bracket. That is the only thing I am waiting on. It has been about a month and a half and I am getting itchy!

I have everything I need to do the whole turbo set up except for the the oil lines, now I just have to wait for it to warm up a bit outside. I hate working in the cold if I don't have to haha

I never recieved the bracket or a response from the Ebay E-book guy. I sent him $60 2 months ago now. Stay away from this cat.
I made my own bracket to mount the turbo and will start more work on it today. As long as the temp is in the mid 30's i'll work on it. Otherwise it will sit. :)

What do you guys think the best way is to add extra fuel? I plan on using an FMU with 19lb Ford injectors. I hope it will run like stock off boost, and the FMU will add extra fuel by pinching off the return line under boost.
I hear of others using larger injectors and an adjustable MAP sensor.
Since all MAP sensors have a 0-5 volt output, I wonder how well it would run with double the MAP sensor (2 bar) and something close to double the stock injectors (36#ish)
To me, the FMU seems like it would have less driveability quirks. I've built several supercharged Mustangs and the simple set-ups were always the easiest to drive.

I have also noticed something about the turbo cartridge position on the Jeeps i've seen. Most don't have the oil inlet pointing up, and the drain pointing straight down. I always thought it was a good idea to have the oil drain pointing directly down. I reclocked the cartridge and the scroll on mine to make this possible.

What version of the 2.5L is this on?  OBDI or OBDII?  That will make a big difference in which injectors you need to use.  You'll probably want to run a wide band O2 sensor as well so you can monitor the flow.    You could try using a adjustable MAP sensor or changing the pressure of the fuel rail as well.  Another option is what Rimmer Engineering did and run a 5th injector.  Another option is to get a stand along computer to run everything and toss the stock unit.  There are a bunch of different ways to get it done.

OBDI, 1995 YJ. I don't want to get too crazy with it. I want to keep it a cheap as possible.

Where could a guy find an adjustable MAP sensor?

Make one or else check Turbocity.com

Turbocity wants like $130. Any idea how to make one?

[chardrc]

google "how to make an adjustable map" and there should be some good info... and i think there was a thread about it hear about a year ago.

Found it. It looks easy enough. Playing with that stuff without a wideband is kind of a crapshoot though, at least when tuning with boost anyway.

Just be carefully when making it.  If you don't it will be an expensive fix.  A member found out the hard way a while back.

I found this link online...  Maybe it will help you.

Hey Rob What size FMU did you pick up i am putting together all my parts for my Turbo-TJ im gonna run 36# injectors an FMU, debating the adjustable MAP. the turbo will be a T-25 and all the exhaust will be madrel bent and MIG welded, just trying to figure out what size FMU to pick up.

Thanks
John

I am using a 12 to 1 FMU. That is the disc used for 19lb injectors (which I am running) on a 5.0L Mustang. With 36's you would need something like a 6 to 1.

thanks alot rob, do you think that 36# is too much, i just dont wanna starve the engine for fuel and blow it up.

thanks again
John
