I have someone offering a friend a "reacently rebuilt" TIV engine and two things stick out to me that give me pause.

1) The current owner claims that the engine was reacently rebuilt, but does not know what size it is. He "thinks" is a 2.0. (IMG:style_emoticons/default/WTF.gif)

2) Claims 110psi more or less on all cylinders. Sounds low to me for new rings and honed cylinders. I am assuming that they are run in, though.


Waht are your thoughts? What values would you expect form a reacent rebuilt?

What you need to do, Rich, is either rebuild the 1.7 stock (not my first choice) or locate a good core 1.8/2.0 and rebuild it to what you want.

What = a 1911?
What = a 2056?

I forget which rod, crank, p/c combos go to each. If you get this info you can start to plan your attack. Is Leo keeping his engine?

For the record, what the guy wanted for the unverified size, rebuild and compression engine was not worth the parts.

Andy was talking about the case. You would need different heads (either 1.8L or 2.0L) then 96mm pistons w/either matching cylinders or get the 1.7L's honed out to match the 96's.

You'll see all of this first hand this w'end as my setup is 96mm p/c's, stock 2.0L crank/rods, 1.8L heads all built off what *was* a a1.7L case. The 1.7L case can be used for the other sizes...
