You should decide what bhp you want from your car before spending any money on the engine, if you are happy with 250bhp then try and get a complete low mileage z22se engine and fit that.
But you will need to replace both chain kits on any engine you use, unless they have been very recently changed (they are all due for replacement due to being at least ten years old), look out for the later spec z20net chain tensioner with the bulge.
If anyone knows of a low mileage 2.2 for sale please let me know
Would you be interested mr Vock in a rebuild,
It's a m62 charger
So 250 bhp sounds ok
But you always won't more
Does anyone no what you can get from the charger
