I have bigger injectors and a walbro 255 fuel pump. my question or need help with is. I need to find a product that will allow me to piggy back my computer, so I can have it properly tuned, I have been looking into  the AEM fi/c ?. any suggestions or comments would help nobody in town has ever tuned a jeep or anything like it.

Check out Sean's turbo project and see if that helps...  He's tried a lot of different things.

[chardrc]

best thing so far has been sean's turbo thread which he is now using the split second system which has worked well for him...

[phillsam]

So what do you think the overall price was to turbo your yj?

[Darksurfr]

Does anyone know the thread size for the oil pressure sending unit into the block?  I imagine this is where everyone is getting their oil feed line from and was looking to buy some lines for my setup. 

Sean, are you running a -3 line for the turbo?  -4?   I am going to be running a -10 for the drain which goes in at the back top side of the oil pan in line with one of the main caps to prevent it from rubbing on the crank when the crank comes around. 

I will shoot some links in another thread for my turbo build or maybe in this one but really need to know about the feed line right now so I can get that all taken care of.

Bought LS1 injectors off of ebay which are close to the same lb/hr that the cobra mustangs use.  something around 24# injectors.  If anyone needs a set I have 8 and obviously only need 4.

Also does anyone know the stock fuel pressure.  I dont have a gauge setup or the YJ in a running state that I can test what the stock pressure is at idle.

i'll just answer the general questions, don't want to hijack Sean's thread on the ones meant for him

i'm not 100% (more like 93.7%) but i think it'd 1/8'' NPT (got a mechanical oil press gauge but it was about 3 yrs ago, that should be it but you might want to wait for a second opinion)

Also does anyone know the stock fuel pressure.  I dont have a gauge setup or the YJ in a running state that I can test what the stock pressure is at idle.

39psi without the vac port adjustment (this is for YJ 91-95). 31 psi at idle but depends on you vacuum input (so it will vary with it) - for your calculations you need to use the adjusted fuel pressure (most likely static + boost, but you should verify if that is the case with your FPR)

[st.chevrolet]

Sharpxmen has already answered your oil pressure sender thread size and fuel pressure questions.

My oil feed line size is -04.
For the oil return line do not go any smaller than 5/8" ID, unlike the oil feed line the oil returning to the pan is in the form of foam and depends on gravity to flow back to the pan.
So the oil fitting on the pan must be welded on ABOVE the oil level in the pan. The oil return line must slant downwards until it meets the pan connection, no sharp bends. If you look on page 2, reply #23, 4th picture down you can see where I welded my fitting to the pan.

[phillsam]

So i just read through the thread.

I plan on gathering my parts and wanted to see what you thought

I am going to run only 5-6lbs of boost:

-psc1-002
-19# injectors (have them installed already)
-boost gauge
-air/fuel gauge

Questions-
Im going to use a td04 turbo from a wrx (got it free)
How would i turn down the boost? would an aftermarket wastegate do it?

Also Is the Hesco FPR necessary? Would it run well without it after tuning with the psc1?

Sounds good....um  is the Oil sending unit a male or female fitting?  I'm not at home and I need to start ordering parts? I think there is an elbow down there.  Is the elbow a 1/8" male NPT X 1/8" male NPT and the sending unit a Female?

oil sending sensor is male, you have a threaded hole in the block. i did not have an elbow but yours could be different - check the FSM, your answer should be there.
