Just read this thread http://www.jeepforum.com/forum/f11/8...e-swap-853642/

Can I just swap headers and intake and everything onto the 88 head? That would save me a lot of trouble.

Headers if aftermarket should be OK. Well, 87-90 headers have a bung on them for the EGR tube. You could have a bung welded on. The latter intake ports have a different port shape. They can be welded up and recut to match the latter ports.

Thanks a bunch Tom, sounds like I will be using my 93 head then.

Hmm... I rebuilt my 2.5 from top to bottom in my barn. lol.

However, I am not really going to lecture you on how to do things since that would just crap up your thread. Anywho.. heres what it cost to do what we did with my 2.5 (now 2.7L and puts out as much torque as a Renix 4.0)..

-Head Work was about $170 (New stainless steel valves, new springs @ 65lbs,new rockers, lifters and pushrods)

-Block Work & Parts was about $500 (bored and decked, stainless freeze plugs, forged rods and pistons, new mild cam from Melling, high volume melling oil pump, crank was turned and reused, it was stroked a bit to improve torque)

The entire block and head was boiled, then boiled again after a flush to make sure everything was out. It was then painted with high temp engine enamel to prevent rust. As a result, this engine is as clean as a whistle.

Keep up the good work, thanks for keeping a Jeep alive also. :-)

There should be a temp sensor on the 91-95 heads on the drivers side. I don't think the Renix version (87-90) uses it. So, you should probably plug it. You might look into porting your heads. Probably a days work. The intake side keep rough, about 80 grit. The exhaust polish as best you can. They do make a porting kit.

The head on the 88 does have the sensor in place like my 93 head. I'll definitely take a look into the porting kit. I noticed that in your post on page three, #40, you recommended that I use my cam or a new one. Is the cam in my 88 block different from my 93? I really appreciate everyone's help so far.

The cams should be the same from 87-95:

Okay, finally updating this thread out of necessity. Cylinder 5 only has 30psi. I also have a great dependable job (Go Bulls!) that I can walk to. So time and money shouldn't be a problem.

Now to decide if I should use my current block or the '88.

I'll up load some more pics soon! What does a white coating of powder on the exhaust manifold on the inside of cylinder number 2 and three mean?
