ok, i read up on some procedures in doing this and supposely the point of all this is too make the ECU still think the engine is a S4(while its a S5).

i got the intake/exhaust manifolds and TB... TII fuel rails, ECU, AFM

what else do i need?

i know i need a TII tranny and upgrade the fuel pump... what about the driveshaft? any changes in that? or should i get a custom made one? well... i was thinking if i needed one, i'd get it from this place... http://www.pstds.com/

well, after all that, would everything be plug and play.

 

not doable?

 

If you are keeping your n/a diff and using a TII trans you need a custom driveshaft. You can get it at mazdatrix.

You don't need a tII tranny but you would be wise to use one, with a TII Tranny you also need - TII Clutch Slave Cylinder, TII Clutch and PP, TII Flywheel

 

so i'll need to replace the master and slave on the clucth, and what's PP?

and i'm hoping it works out because my diff is the lsd diff... i have the 88 GTU

 

You don't need to change the clutch master, just the slave. PP means Pressure Plate.

 

oh haha... i was trying to figure it out... think power steer, p, p, p.... pp what? :P
