hi guys,
other than gearing, is there a difference between an NA and TII 5 speed? thanks.

 

They're completely different. What are you trying to do?

 

different weight.(about 30 pounds difference),structural integrity..different sized output spline for the driveshaft.
Seeing as one trans will only hold about 225 hp(N/A) and the other is Made to hold more(TII) ,it is like night and day.

 

can i am looking at has NA 5 speed but 13b w/ street port. making sure it can handle it or if i will have to upgrade in the future.

 

It's fine for an NA. A TII transmission will have better internals, but using one with an NA engine and rear end requires a custom driveshaft, TII trans crossmember, TII starter, TII flywheel, TII clutch/p-plate and TII slave cylinder.

 

so i should be safe w/ an NA 5 speed mated to an NA street ported motor. thanks rocket.
