quick question- will 2L barrels fit on a 1800cc engine without machining?

I have no sympathy for my car, only the wallet that pays for it!

But...

you will need to either machine the pistons for the 66mm crank (not sure how feasible this is?) or use the 71mm 2l crank (different wrist pin heights)

The following is from http://www.tunacan.net/t4/tech/

"Plan carefully if you are thinking about mixing and matching stock pistons, cylinders, connecting rods, and cranks. The wrong combination can give you too much deck height or move the piston out the top of the cylinder. For instance, installing 94mm piston/cylinder set on a 66mm cranks with stock rods will yield way too much deck height. Installing 90mm or 93mm pistons on a stock 2.0 bottom end will push the piston out the top of the cylinder."

(94mm is stock 2l piston/cyl. 66mm is stock 1.7/1.8 crank stroke).

very simply a mate has a 1800. the valves have all burnt out. he does have a spare 2L which needs rebuilding. he is getting teh 2L heads rebuilt to go on the 1800 engine, and was thinking of also putting the 2L barrels and pistons. so this will increase the compression to much?

No too much deck height, ie not enough compression. Could machine the cylinders down, but not a cheap fix.

Probably better to get the 96mm P&C's from aircooled.net that fit the 66mm crank, gives an engine size of 1911cc.

But if he has a 2l engine why not use the 71mm crank? With 96mm P&C's, 2056cc... nice, apparently gives 100 - 120+ horse with the right stuff, that will last for a lot of kilometers.

he will be rebuilding the 2L fully with new barrels and pistons. just looking for a quick fix to get the car back on the road.

Fair enough,

In that case I'd stay with the 1800 pistons and barrels
