I'm thinking about taking my stock 1.7 to a 1911. Some old threads seem to suggest that you can't do this with the 1.7l heads, while others seem to suggest it's fine. Can anybody set me straight on if I would need new heads, if they'd need to be machined, or if I'm good to go?
Also, I've got 2 engines all with original german cylinders. Am I better off taking the best 4 and boring them out or going with new chinese cylinders (local shop recommends QSC). I've been thinking if I've got 4 decent ones that the OE cylinders would likely be better than the chinese stuff. anything else I should be thinking about? |
