I'm going to try and pick up this TII but I want to go ahead and start planning my rebuild. I want to try and use N/A rotors, for a little more torque/driveabillity but I understand the problems with the high compression. So what would I need to do to get it to work "reliably"? Would it just be a matter of more fuel?

 

anyone?

 

I believe you would also have to play with the timing, so motor dont go boom

 

what series?

You should probably just use S5 TII rotors, they've got enough compression

torque isn't an issue with the TII's above 1800RPM..

 

....well, on top of the torque idea...I'd like to have the rebuild ready before I need it and all I have on hand are S4 NA rotors...:P

What's the difference between S4 TII rotors and S5 tII rotors?

 

S5 TII rotors have slightly higher compression. I "think" they may be a bit lighter too, but not sure.

 

S5 TII rotors are 9.0:1 S4 tii rotors are 8.5:1
S5 N/A are 9.7:1 S4 N/A are 9.4:1
