In what years was the 52mm tb fitted to the MG ZR ZS ZT?

All ZR160, no ZS or ZT, (but there is one on the engine I am striping).

Got one on eBay for £28 which seemed reasonable.

I've found a fitting 'how it' but if anyone has any tips that might assist me it would be appreciated?

No tips needed. Just bolt it on and enjoy the fun!

Fitted my 52mm TB and a new Pipercross air filter.

It was a bit of a pain as the bolts are tricky to reach and I got the new one on only to realise I'd forgotten to swap the TB position sensor so had to take it off again!

Once sorted took it for a spin and the throttle response feels better especially at lower revs...a nice improvement for £28 would recommend to anyone who hasn't done it...

Think you're also supposed to re-set the throttle position for the ECU by pressing the pedal four times in succession with ignition on ?

Interesting, what does that do?

Didn't mention it in the 'how to' that I followed...

Switch to ign 2 but don't start it.
Firmly and fully depress the gas peddle 5 times in 30 seconds.
Wait for the stepper motor to stop adjusting.
Start engine.

The process allows the ECU to learn the position of the throttle body butterfly.
