S4 and S5 refers to Series Four and Series Five motors.

- Each motor had a slightly different turbo setup on them.


lwnslw you have 383hp to the wheels in your FB? If so, WOW...i would be scared out of my wits to drive it hahah. =]

Do you have a build thread i can research? If not, you should make one so i can get some ideas. I don't want to hijack this thread but my plans for the FB, power-wise, is 300-350 RWHP.

How much boost can a 12A take? Are their seals weaker/stronger than 13B seals?

How much more torque is added with the small increase in displacement the 13B has, compared to the 12A? I'm sure i can search this..off to search again. =]

Feel free to chime in though.

Yes I relocated the drier lower and foward in order to mount the intercooler. Did not to change AC lines to do it. Need that a/c in tampa even if just to clear the window on a steamy rainy day.

Very nice build. Nice to see there are other turbo fb`s out there.
