160bhp mk2.5?

[treadstone]

It's my understanding that the Japanese 'RS' iteration of the mk2.5 came with 160bhp as standard. If I'm not mistaken the 'RS' was essentially our UK 'Sport' model, but the UK car was de-tuned to 146bhp in order to meet emissions requirements.

Does anyone know what steps one would have to take to get a UK mk2.5 Sport up to the 160bhp it was originally designed to produce?

It's pretty well documented that the mk2.5 RS has 160bhp. The mk2 RS however didn't.

From my limited research it appears as though the S-VT (VVT) was tuned for emissions rather than power in the UK.

I agree it would certainly be interesting to find out how the RS made 160bhp.

On a different note has anyone here driven both the mk2/2.5 JDM RS and UK 1.8 MX5's? Would be good to hear how the RS compares in terms of driving.
