It's probably just my heavier foot, but it seems like my car gets a little bit less mileage with this explorer engine. I am quite pleased with the extra power and I like to feel it!! I know trying to read mileage by the gauge is stupid, but my odometer isnt in working condition so I can't actually test it yet. So, anyone else get crappier mileage with the new engine?

CR is still the same I think. The PI engines have a bigger piston dish to make up for the smaller heart shape on the head.

yes the compressionof the non pi and pi engines is the same. smokey i think you confused it with a pi headswapped car. pi heads on a non pi block = higher compression

I noticed a little less gas mileage after I put my Exploder motor in. At first I thought it was due to me enjoying my extra power. I tried to drive like a sane person for a tank of gas or two, but never got mileage as good as before. That was with the stock EEC BTW.

My around town mileage has gone down a tad, but still averages 18 or so. I blame more on the new converter. Haven't gotten a solid road trip to establish if I'll pull 27.5-28.5 again like I did on the old motor. Now that I've got the chip we'll see if it goes up at all.

BTW, C/R is higher on the PI motor, approximately 9.4:1 on the PI vs. 9:1 on the NPI.

I get about 12mpg. But I only drive the car on weekends so I could care less what it gets.

It needs a good tune though.

Exact opposite, a higher compression motor will be more effeicient (but require better fuel).

2.03 for 93? You got it pretty damn cheap, thats nothing. I live in central cal, where gas is usually reasonable, and i pay more than 2.03 for 87! Most places are 2.03-2.11 for just 87.

He swapped in an entire PI engine, not just the heads. As for the compression, yes, NPI shortblock + PI heads = high compression.
