How did Toyota get the engine up to 174bhp from 158bhp and could this applied to a Rev1 like mine??? I have no doubt this has been asked before.

I wouldn't worry about trying to get the extra few horses that the rev 3 car has. The changes from rev 2 to rev 3 are quite a lot and more power can be had by spending the money elsewhere.
Power gives the ability to sustain high speeds. Torque gives the ability to accelerate. So high power means a fast car and high torque means a quick car. Rev 1 and 2s have T-VIS which effectively lengthens the inlet tracts, increasing the velocity of the incoming charge and thus the volumetric efficiency. Basically T-VIS increases torque at revs below 4300 and the system automatically switches out over that range. Rev 3 on cars have ACIS which does a similar trick but doesn't give quite so much low down torque as T-VIS, which is why the early cars are quicker 0-60.

The delimiters mainly work by converting KMH to MPH by dividing the speed by 1.6. Unfortunately this has the effect of making the speed sensitive power steering think it is going slower so instead of diminishing to zero assistance at 50mph (80kmh) it will stay in until 80mph. There are clamping types available but they are quite expensive. I am working on my own design clamping delimiter, waiting for the prototype PCBs to come back at the moment, but they will be on sale on www.twosrus.co.uk in the near future at around £60. They will correct the speedo from kmh to mph, make the ODO count in miles and will not effect the power steering.

you can get december93 rev 3's.

Sorry, don't know the specs of NA's

You can indeed - Mines outside (fingers crossed!)
