Yea, as soon as the TZ Speed showed on the market I bought a TZ 5 port and did almost all mods that the TZ Speed shows in pictures...except for the crank....which in the TZ Speed has about 8.5mm bore.....the TZ 5 port has 7.5mm.
Performance of my engine is AWESOME!!!!....I will try moding a crank as the Speed's when I get the proper tooling
