Save Time! Upgrade The 2.5L 4Cyl Jeep YJ Intake Manifold To a TJ Intake Manifold 

Thanks! It's new. I'm impressed that you watched my video, which has absolutely nothing to do with your vehicle.

You may end up with too much throttle body doing that but I like the creativity! Thanks for watching!

They must have gotten rid of it by 95. I have seen some 95's with the newer style intake manifold.

I'm not really sure, I have heard that megasquirt works well

When you say 9psi with the key on, is that with the engine off? The fuel pump runs for a few seconds when the key is on then turns off if you don't start the engine. With that said I wouldn't expect there to be much pressure if the pump has run then turned off. 31 psi sounds fine when running and it should go up around 39psi if you open the throttle. A loss in power in higher gears is pretty normal for this underpowered engine. My best advise is to clean everything, valve cover (inside and out), intake manifold, throttle body, injectors, etc. Check for any vac leaks. There is a vac line that runs under the dash to the heater, those leak sometimes. Move the inlet air sensor and shift gears at like 3500-4000 rpm (or higher). One thing I noticed is that when shifting gears, often times if you shift at 3k it will drop you into 2k-2.5k rpm in the next gear where this engine has no power and it will take a long time to work its way back up to 3k+ where it makes power again.

Lol Yea, this pretty much doesn't pertain to you. Unless you are upgrading to the serpentine belt, then I recommend taking parts off of a TJ. (Hence the video)

I didn't have to, but I did because theoretically, it should be better to have matching hole sizes.

@@JeepSheepTV Excellent, this month I start with my modifications, I will follow your advice 😃

Oh yea, running great

Not likely, they are pretty different

They are out there

I would think that you would want it on CCV (the big one) It seems like many of these engines have quite a bit of oil coming out of there onto the air filter

@@JeepSheepTV ccv valve is on the side of the cover with a small hole in the brass fitting and the pcv valve is in the back I’m going to try hooking up a larger diameter hose to the ccv into a catch can and then to the intake . I have no leaks Just a smell of Burt oil here there , more often when Traveling and slowing down

@@Drake621 I was thinking of the PCV then. Did you see my video about cleaning the valve cover? It helps with the oil smell on decel. They get clogged up pretty easily

I forgot about power steering being an option. What does yours use to tension the belt?

@@JeepSheepTV it’s essentially just a pulley on an arm, I will verify tomorrow

Junkyard or ebay

I know a lot of buttheads. To whom are you referring?

@@JeepSheepTV just prior to the one-minute mark, 50 seconds maybe 55 somewhere and there I could swore I heard Butthead of Beavis and Butthead Fame

... nope
