fuel tank has a swirl pot in it plus if the car ur putting it all into isnt fuel injection then u need to change the fuel lines, plus all the other parts like ecu mounting brackets, boost hoses, water hoses, air box, fuel metering unit, injector pipes, antiroll bar, header tank, dizzy and lots of small clips and other parts plus you will have to uprate your brakes & suspension, its so much easier to buy a rotten erst park them side by side and swap everything over that way u can see where everything is ment to go and it will work out alot cheaper in the long run
