we have set a record for the times "old" was used in a thread title................ and it is appropiate!
Alas--when you buy a used engine the maintainence history is unk. All I do know was the milage and that it was not taken to a dealership on a regular basis. It did have good compression numbers when I received it.
The gas starvation was on the back straightaway at Road Atlanta. Short version---gas line spacer came out and starved the engine before I knew what was going on--I was doing about 100mph at the time.
I drove the car approx 100miles home on one rotor after the rear rotor let go.
Maintainace ---
once i received and installed , it was good. I pre mixed 1/2 oz to the gallon , high test gas only of course, i run a pettit s.c. with no more than 9lbs of boost, it nevers sees coolant or oil temp over 210F. Usually it is around 170-190 range, I also run an intermitent w/m system. It is not on all the time. I will use maybe 1 gallon every 2 wks or 250miles.
I was pulling 320 g/secs maf flow so the engine was in fair shape.
After I received it there was never anything under a 40W oil in it. I used Castrol GT 10/40W on the street and 20W 50 on the track--this was before i discovered deisel oil. It has about 4-5 track events on it. That = to about 1K miles of track use?
Changed oil every 3 K, along with filter. Filters I used were either mobil 1's or a Pure one Purolater, + 1 K&N.
It was decarboned once with the mazda stuff about 1 1/2 yrs ago.
I do not drive that hard on the street--dont redline once a day
Oh yea since I have had the s.c. up and running my redline is now 7.5 K with super max redline of 8 K
My s.c belt is adjusted to normal tension as the other belts on the car.
It also has a dedicated belt for the s.c. only.
The engine is clean--oil pan--really clean.
Pretty good shape if you ask me.
Thanks Paul---a bunch.
The new engine rocks also---Rick E/Paul engines are a good way to go.

the bottom seal is the warped one, right Paul? Did it lose that end bit in the engine or later?
btw- was anyone else going through these pics trying to find stuff in the backround? like the engine under the table....
