Actually I think you need to know which direction you intend to go with engine modifications up front. Turbos would require going a different direction regarding cams, compression ratios, exhaust flow and ignition. I don't think the Houston engine would benefit from a turbo because their direction for increasing horse power and torque, while great and accomplishing what they intended it to do, wouldn't be the best approach for super charging. I've had a turbo for years and it has required periodic tinkering. I enjoy it ( I like to tinker ) but the Houston engine is very close to the original regarding reliability.
