Thanks!! I think the recent big bore kits are definately a viable option for anyone who already owns an RX3. With the recent sale price of $111 (reg $300) it would be a no-brainer!! I would think it would be a no-harm-done, it's worth a try type of deal. For myself, I was committed before the big bore kits hit the market. I have no regrets what-so-ever, the big bore might net 5hp and 6 ft/tq ? (no idea, just a guess) The engine swap has gained much more power than that, and was alot more fun to put together. I'm not going to lie.... half the fun was just seeing if it would work!! Obviously, maybe not something everyone can tackle, but not terribly complicated or costly either.
