I have change my stock manifold to a extractor with and a two half muffler system but wonder if I could use a sr20 computer on the sr18 engine it's nice a agressive all when I use just extractor alone without muffler feels good but take petrol what else can done to sr18 engine

You don't say,but I'm assuming this is a Nissan from your details.

A sr20 ecu won't help.
For a start it will be set up for a. 20 not an 18 so even if it did plug in ( which is very doubtful) you will need to tune it. This Needs some clever electronics with different boards and if you can do it to the 20 ecu you can do it to yours.
You need to go to a forum specific to your car to find out exactly what to do
If it is a primera this will be easy to find as there is much detail about this car on the internetty
