Hi,bit confused myself i have a 91 uk tt and that has a cat ,didnt think they had cats on the earlier cars?

here you go.... from the parts list....

 

for a mid year 91...

http://nissan4u.com/parts/300zx/el_z32/1991_7/type_1/exhaust_and_cooling/exhaust_tube_and_muffler/

All Z's have at least 2 catalystic convertors (Uk's have an additional pre-cat as well for a total of 3).

 

All pre-95' Z's are tested using the standard non-cat emission rules for MOT's, becuase the Z is not in the emissiosn database.

 

Which means, providing there are no other problems with the vehicles emissiosn a pre-95 Z will pass the Mot emission test with the Cat removed.

Thats good info, if i removed my cats would that make much difference to performance ie bhp.

there will be some bhp increase but i dont know how much on a zed. i think i read somwhere that on some cars a cat can takeaway up to 10% of the power of the engine?

 

Thanks, i'll leave mine on i think ,i wouldn't want to de cat unless there was a noticable difference.

mines a 1992 na decatted asked vosa to send me details so could show mot tester passed no probs

Being a turbo'd car yes, can be very noticeable on acceleration mate.
