If i was to put a C20XE in my 1995 corsa GSi,do i by law have to keep the CAT,if so will the existing one do?
Although early XE's dont have provision for a lamda sensor so would i have to get a later engine with lamda sensor?
I might just remove the insides of my cat and use that so it looks like i have a CAT for the MOT,as long as it passes emissions.
What have other people done?
Originally posted by astraderv Not neccessarily- it goes on the age of the engine, whether you need a CAT or not. It's up to you to satisfy the MoT man that your lump comes out of a pre '93 motor.
I used to think this too.
The rules are, the car is tested on whichever is older, the engine or the vehicle.
If it's a pre-'92 car, with a '99 engine, it doesn't need a cat.
Likewise, if it's a '99 car with a pre-'92 engine, it still doesn't need a cat.
so what is the best thing to do?
A. Get a pre cat 2ltr 16v
B. Get an engine with cat,remove cat so you are still using the lamda sensor?
Also,on a nova you have to modify(bash with big hammer)the drivers side of the engine bay to make it fit,do you have to do this on the corsa gsi,and is the shell of a corsa gsi weak like a nova so you have to stitch weld and strengthen it?
