2.0 8v exhaust bore
A mate is putting a cav 130sri engine is his nova, he's getting a custom exhaust made and asked me which bore he should go for.
He's going to put a c20xe in when he can afford it so will want the exhaust to be good for this.
Whats the standard bore on the cav?
What would the best bore be?
Something like 2.25"?
2.25" would be fine on the 8v and pretty much perfect on the 16v IMO.
I had a 2.5" on the 16v but it seemed to hesitate quite badly at times. Its much better now with the 2.25".
