the os engines would be the ones to go for, cause they're easier to tune and have a good reputation for reliability. as for ports , a 3 or 5 port refers to the number of inlet slots in the piston sleeve that feed the fuel mixture into the combution chamber, generally an unmodified 5 port motor will have a little more power than the same type 3 port motor , hope that helps you out

Go with the OS TZ 3port. I believe it will be easier to tune and its torque and speed should be controllable. Its about $5 cheaper, and if you ever decided to sell it, it would be easier since 3-port is standard for racing sedans.

ditto. nothing is easier to tune than an os motor. the tz is pretty fast also.

I don't want to burst your bubble but have you tried to lean it, most engines aren't gas higs unless there .32's. Also the OS line is the best 100%.
