My buddy just got a '98 Expedition. I have a blown up 2000 F150 at my house. Is it worth swapping the intakes? Any other parts revised on the motor? I thought I'd give him the parts if anything stands out worth swapping.

I know, more dumb questions. I'm not real wise with mod motors. I've always had 5.0 and 5.8 windsors.

 

What engine? 4.6 or 5.4

If they are 5.4's, your buddy's 98 is a non PI motor, yours would be a PI. Which means it has the performance improved heads = more hp.

And whats "blown up" about yours

 

intakes are not swapable between PI and non PI engines. If he took the heads and all its possible lots of work though.

 

Yea, doesn't matter what's in the Expy, - Swap in the 2000 heads up.

It will only happen if the 2000 heads are good.

And if you add LT's and E-Fans at the same time (spend a little money) , it would be nice jump in horsepower. At least 60 HP 70 Torque.

 

 

fixed it for you, and YES HPS offers the adapters...

 

Still, what gains would just a manifold provide ? Now that I think about it, there was a guy who did this on a Stang. From what I recall, he did have gains.

I believe he had to re-route the heater core tube for some reason. Might be just a Stang thing tho.

 

Jbrew, the PI heads will work with the NPI manifold IF the OP uses the adapters

however, with the OP blowing up the PI motor, who knows how much damage has been done







they are the ones doing the work and I have no idea why swapping over the intake manifold came up but if they want to do it, it's thier time thier money and effort

 

I thought you were referring to bolting a PI manifold to NonPI heads. I've seen that done on a Non PI Mustang engine. I thought you sent me the link lol. That was a awhile ago tho.

But yea, the heads MIGHT still be usable from 2000. When mine blew 1/3 of the piston ended up in the lower intake lol.

 

yeah that was me that sent you the link, but I have no idea what the OP of this thread is trying or wanting to do...

 

Probably more power and whether or not it can be done. The 2000 would be getting a new engine anyway, I expect. Trying to find a use for the old, - maybe.... ?

So, IF the engine didn't over heat and the valves are okay, - should be able to use the heads as is.

But yea, OP needs to fill us in.

 

The 2000 truck is junk. Half of the sheet metal is rotted away. The 5.4 out of it had a rod bearing spin and come out. However, it had everything gone through and rebuilt 60,000 miles ago(including the heads).

My buddy, whom which I trade parts back and forth all the time, got a '98 Expedition with the 5.4. I didn't know the heads were different. Only thing I recalled hearing is the intakes were slightly better.

The 2000 has some shorties on it, too. So, looks like I'll pass the info onto him and let him decide if he wants it. Otherwise the motor was just going to get ripped apart and parted real cheap, or scrapped.

 

I know on the car 4.6L. Swapping the PI intake onto the npi block and heads is a nice gain about 10-15 rwhp. add the pi cams advanced 4 degrees and you look at 30rwhp gain. I can't see why you would need adaptor plates to make it work.
