I done some ringing around and found out that emmistion testing is 700dollers a pop at regency. You can engineer coilovers but they must have 2,3/4 travel so that puts a lot of brands out, bigger rims can be done but must have tyre size chart sticker on the car(cost more)
After talking to a few Engineers i found out that Emissions testing in adelaide is still going thro some loops but will be sorted out soon
So i recon im going to machine the rb30 of the block lol and change to a stock plenum put the power fc in a stock ecu shell for now
