BTW, youj can fit a bigger filter if you want. The flat surface the filter mates onto is quite large. Just get one with same thread & bigger body & it will work OK.

Might want to check to make sure you can drive a VQ35de Stagea.

Can't legally drive a VQ35de Skyline in Vic and NSW, so maybe SA have followed suit?

VQ35 Stagea should be fine, over here the regulations are

High-powered vehicles

A high powered vehicle is a light vehicle with a Gross Vehicle Mass of less than 4500 kgs that has:

  • 8 or more cylinders
  • a turbocharged or supercharged engines(except diesel powered vehicles with less than 8 cylinders)
  • been modified to increase engine performance (link to vehicle modifications section below)
  • been nominated high performance vehicles - refer to the list of Included Vehicles in the High-powered vehicles notice below.

And the high powered list doesnt mention the VQ Skylines thumbsup.gif

    • Yeah, you are right. It seems easier and more reasonable to boost the engine. And as you said the blocks are very similar but the cylinder bores are different.
    • Sound logic, but in actuality way more illegal than just having the wrong pipe. Normally, doing something like that would be forgery. Meaning you may have certain documentation for vehicle parts, but the actual parts are different ones and you just assign them the numbers and badging from the documents. But nevermind that. Nonetheless, I AM curious if this pipe was ever made by any official manufacturer this way, because I honestly am not familiar with this pipe layout and shape. As I will be putting on the HKS Silent Hi Power once my exhaust gaskets arrive, as long as it sounds right I will just roll with this front pipe. I can always order the actual Mines part if I run into legal issues. It would be an unnecessary expense as there is lots of other problems I have on this car as of now.
    • So, weld a plate with the Mines logo laser cut into it, onto it. Instant Mines pipes, whether they were or weren't originally.
    • I don't know if the blocks are "the same". They will be very very similar. Obviously, either the bore or the stroke is going to be bigger on the 20. If the bore is bigger, then the 18 head is unlikely to fit properly. If the bore is the same, then you can almost certainly fit the CA18 head, but there migth be a few fun things you have to do to make water galleries (or other things) line up properly. Or... it could just be real easy. Is it worth the effort? Almost certainly not. You can make nearly as much power on a 2 valv ehead as you can on a 4 valve. There's not any "magic" in a 4 valve head.
    • Yes, me too!!!!  I need to find a something that has all the abbreviations for what these cars have LOL
