I'm curious to know what the differences are between the Rover BRM and the MG ZR 160. I know that they're both based on the same Rover 200, but what are the differences under the hood that give the MG that extra power ?

52mm TB in stead of 48mm, other exhaust, other injectors, other ecu and some headwork.

Cam profiles, ecu and injectors are all the differences (inc throttle body) IIRC

I would love to give my BRM a bit more power. What's the best (read 'cheapest') route to a faster BRM ?

I also wondered how these type of modification affect insurance ? Do you have to pay a lot more to insure a modified BRM ?

First mods i'd go for are the 52mm throttle body and a decent panel filter, probably around £180 altogether. You wont see amazing gains but its the best starting point.

mg zr 160 only 5mph faster top end but slower on acceleration brm's are still better

zr 160 is missing a torsen, this to some is a pointless addition, but I certainly noticed it when I moved from a 1.4 25 to the BRM.

Some people say the torsen doesn't do anything. Personally i agree with you Jon, when pushing the BRM into the twisties it alloys for a lot more power to be put down onto the road than my standard 200 ever did.

A common misconception is that the VI is quicker in first gear, the inside wheel will spin easier when, for example accelerating while turning out of a junction.

This doesn't happen on the BRM (as much) but this is down to the torsen. I test drove a Rover 25 GTI and have to say the BRM is much better when cornering.

I haven't driven a ZR 160 so cannot comment on that so only going on how the 25 GTI drove.
