with 0 overlap at normal drivng load , an not looking much different than a normal sr the big problem is the egr but it doesn't need one it runs clean like a VTEC(no egr).
We don't have anywhere near as stringent emission testing for older cars in the UK,though it's getting tougher on new cars.I've got an Ecotek valve fitted to mine which basically creates a controllable air leak off the inlet manifold and leans the mixture out as much as I want.At my last MOT(An annual test of cars road worthiness)my CO level was about 8% because my car is decatted.When I adjusted the valve(by opening it),watching the readings on the diagnostic machine I got it down to decimal places!When the test was done,I closed it again.
Does this Ecotek thing do any good for mpg or performance on a U.K. Primera? Their website claims miracles, but there are a lot of testimonials from reputable magazines that seem to substantiate their claims.
SteveB,it doesn't on mine as unbeknown to me when I bought it,they don't work on turbo cars.When the car comes on boost,it closes the valve,stopping it working.It works at idle though as there is no boost.
