Nice. I would've painted the oil pump silver too.

The filter pedestal? I took it back off and will paint it eventually. The engine is empty at the moment waiting for funds to become avalible.



These are 13B rotor housings, but it shows the different spark plug shrouds over the years.

Sorry, I call it a oil pump, cause oil gets pumped to it and through the filter.

FD(93-95) vs GTX(89-91 TurboII) rotors.



Besides being equal in weight and compression the FD rotors will show the vertical machining lines thru out the compression sides while 89-91 turboII will only show them on the "bathtubs" only as BDC mentioned earlier.

I bought a US s5 core engine and the rotors had the vertical lines on the entire face, like the fd rotors. The engine came out of a 89 TII. Not really sure how this happened. Since all my other s5 rotors only had the maching lines on the bathtub area.

i think they have 2 different machines. sometimes the rotors are beutiful and some arent. even if you compare new vs new. also some have deeper grooves machined in the face than others. i'm talking about s5 and fd only here

Which one is more desireable, the smooth one or the one full of lines. I would think the smooth face one would be better.
