Custom trans gears
 

Has anyone ever changed their transmission gears?

Who could do this type of work? How much hassle would it be?

My premise for this thread is the thought of going with a higher rear end and changing only 6th gear to pull your highway RPM down. (no SRM discussions)

Thanx for all helpful input!

Pfitzner Gears in Sth Australian list a conversion for Nissan 5-speed and the R35 6-speed transaxle but have no announced plan for the 6-speed trans in the Z34.

You can expect this to cost well north of $9K (AUD) plus labour to strip and re-fit .... based on the PPG Gearbox web-site prices for the 5-speed.

The other alternative is to get Holinger to put a box together - gear ratio choice found here:

but expect that to cost north of $20K (AUD).

Remember that you need to change the layshaft gear as well as the main-shaft gear as they need to be compatible

Whatever you do, it will not be cheap.

Research the threads one guy on here did a trans job with ford syrncho's

Great video on how they work.

I believe he did all his for 3 grand
