'95, thanks.  I'll get some wiring diagrams.  Right now I have no documentation.  Are the Hayes/Chilton any good for this vehicle?

'97, thanks for the '04 shot.  The '02 2.7 I'm getting has the high-flow pre-cats attached.  Not sure if the main cat will be included or not.

JDM, what vendors are you looking at?  Those are the exact mods I'd like to do since I'll be messing with all those parts anyway.

Here is a shot from below showing the y-pipe removed. Had to unbolt the front drive shaft to allow clearance for pulling out the exhaust.  The 2x4 is meant to keep the tranny balanced once I pull the engine.



All belt housing bolts have been removed, but my "angle" doesn't allow me to pull the engine assembly off the transmission.  Perhaps I need to remove them as a pair after all?  I did remove the rear brace holding the tail end of the transmission, which gainded me some relief, but I still got a ways to go in order for the oil-pan to clear the front diff.

Here's a shot showing the most angle I can achieve right now (which still isn't enough to allow the oilpan to clear the front diff.

Just pull the front diff out of the way. It's only a few bolts and will make your job a lot easier.  
While it's out find your self a steel housing and carrier ;D.

Do you have a pic of the Y pipes on the motor. I got a friend that did a custom wpipe for the 2.5 and a 2.5 cat back and he said it woke that motor up big time.

More pics thanks if u want i can host them too

Dropping the diff made all the difference.  Here is the engine being pulled out:



And here is the empty engine bay:



And finally a shot of the engine w/ the y-pipe bolted back on.  The pre-cats are bolted directly to the exhaust manifolds.  A set of long-tube headers along with a custom y-pipe and exhaust sure would make this engine breathe a lot better!  Look at that sharp 90 on the passenger side pre-cat outlet.  A nice smooth y-pipe sure would help.

I can not wait to get my truck saturday.

Now does the 2.7 have the same size manifolds and downpipe??

I know the cats are part of the manifolds.

Are u interested in selling the whole motor compete the blown one??

That is a very good question and one that I should know the answer to once I sit the 2.7 next to the 2.5 and try to mount the 2.5 y-pipe too it.  I'm hoping the 2.7 comes with the y-pipe, but it may not.

Sure.  It will depend on what is included with the new engine.  Thinks like the starter, alternator and torque converter, etc.  Once I get the 2.7 up and running, I'll be happy to part with the 2.5 along with whatever is still attached to it.

It is the connector coming from your 2000 dash harness to the ECU E61 connector.
On the XL7's,the MAF and IAT sensors are part of the under hood harness,not the engine harness.


Are you sure about that '95?

Below is the wiring diagram for the 2000 2.5, and it shows the MAF going to C51-3 pin 23, and the IAT sensor going to C51-3 pin 8.



And here is the 2002 2.7 diagram showing the MAF going to C51-3 pins 5 and 10 and the IAT going to C51-3 pins 1 and 10



A lot of other stuff appears to have been moved around.  I'll need to study this a lot more before re-connecting the battery from the looks of things.  :-[

 ::)Ok wait until you have it all together,then tell me how many wires you have to swap around in the harness.
You do see that they have different Mass air flow sensors and the wires go to different connectors.
But it's still a easy swap.

I picked up the 2.7 this afternoon.  It's the rusty looking one on the right.



It looks like it has been sitting outside for quite some time.  I'm sure the internals are just fine as I can turn it over by the flywheel by hand.  I'll move all the pulleys, shields and brackets over from the 2.5 since nothing has rusted on it.

Here is another shot of the 2.7.  Notice the complete harness with the computer attached.  It is very fortunate that the harness is complete because I think I'll be better off just replacing my GV harness with this one.  The main reason being that one of the 3 ECU connectors are different.  In addition, the 2.7 has different sensors in different locations, so just retaining the 2002 harness will likely make things easier.



I'll need to move the flex-plate/torque converter from the 2.5 to the 2.7.  In order to do so, I need to un-sieze the 2.5 so that I can get to the 4 bolts holding the torque converter on.  Looks like I'll have to drop the oil-pan, unbolt the rods, and the pull out the crank in order to accomplish this unless someone got another idea.  Even my 600 lb/ft 3/4" impact wrench isn't able to turn the crank on the siezed 2.5

Btw, the 2.5 y-pipe fits the 2.7 perfectly, although I'll be looking for something that will flow better at some point.

I think you got your user names mixed up I never said anything about MAF or IAT sensers.
I *think* it was 95XL-7 that was talking about those. ;)

STUNT do you have MSN messanger?

So whats the differenece between the 2.5 and 2.7 outside? same size manifolds and so forth??

Also is there a secondary o2 behind the second cat?

Yep, you're correct, it was 95XL-7.  I edited my post.  I guess the 7 in XL-7 made me mix up the user names.  :-[

JDMCRX, I don't use messenger.  Here is a quick run-down of the obvious visual differences (going from memory from last night):

* Exhaust manifolds are idential
* 2.7 intake manifold is taller near the throttle body and appears to be lacking an EGR like sensor on the left bank.  My 2.5 had California Emissions.
* The A/C compressor bracket is different, so I'll be moving over my 2.5 bracket.
* Power steering brackets are the same.
* Other pullies and the belt tensioner are identical.
* There are O2 sensors before and after each pre-cat, I don't believe there is a 5th O2 behind the main cat.
* Fuel line paths are identical.
* Misc sensors are different and in different locations.
* Oil pans are identical, so I suspect the 2.7 came out of a 4x4.

Yeah u will probly need to switch the intakes maybe.

I may be interested in the down pipes and exhaust manifolds if u willing to sell. also the fuel pressure reg cause my truck needs one .
