Its not about knowing an engineer, if you do it properly and work with an engineer they will sign it off,
It is their name that can be tarnished, and be served with severe penalties
In saying that there is a TG gemini with a 1J in it, yes the years differ from ADR's
I have a mate who is puttin a 2J in a 1200 coupe and will look to be signed off
And there is an LS3 KE70 getting around Redcliffe also,
If you have the money any engine can put put in any car, also look into the ICV laws also,
