may i know is os tz 5port with the black case can be fitted with 3port tz or xz speed crank shaft,p/s,conrod? im abit of confuse since some say yes and some say no..

yes you can with tz 3 port, but por performance, do so with 5 port as that crankshaft is a little bit wider if i remember correctly, besides it costs $7 more in tower

for the performance i do beat it will be low then the original os speed right?i do see 1 of my friend using tz 5 port with os speed crank shaft and p/s but not yet test it and he away for offshore..

no idea for this, but then, a speed crankshaft is expensive compared to stock 3 and 5 port, and then, you have spec 1 and spec 2 speed!

the price for the crankshft much expensive and i just check with our lhs,as he askng me to buy new os speed 12xz as i could spent around the same price if i rebulid the tz 5port to 3port speed tz spec 2..

this is right way to go!
