oh, no no no,i meant going with parts that would be stock on the different engines, instead of aftermarket hi performance parts. I know i'm going with the ld28 crank and 240z rods, but i'm not quite sure which pistons to go with. i'll need 88mm pistons with the right pin hight to get me in the neighborhood of 9:1 compression ratio. a lot depends on which head the 240 i'm getting has. I'll have to wait and see which one it has. (is there a stamping on the head for the model?)
I know as a fact the car i'm getting doesn't have the stock head. the head on it gives less compression, but apparently it performs a bit better, so i would have to assume it means a bigger combustion chamber with larger valves. the E88 doesn't have much bigger valves compared to the E31, so I'm thinking it might be an N42/P90
funny thing, the site you gave me, i've had bookmarked for a month ^^
I'm not really looking for cost savings, but if the car i'm getting has a good set of internals, i'll rebuild the engines and put new rods in it (i've never liked the thought of putting used rods in an engine) and have the head rebuilt. i'll deffinetly get stronger rods if i can find them.
thanks for the help. I've already decided to do this engine build in the next couple years. that way i can save up a massive amount of money to build a nice l24 turbo
