Thanks Lukezen, Thats heaps more helpful.. Seeing $2k scared the crap out of me...
So the price of engineers cert. is different compared to how heavily modified your car is?

Lets say we had a EK with a K20 in it with coil over, asr sub frame, struts, ctr swaybars and some aftermarket LCAs... Stock K20 though .. ?
Wouldn't be as much as $800 right?
