How much effort was it to fit the 18G. What else did you need t make it fit?
Well because I changed from a vf38 twin scroll, so there was a couple changes.
I had to replace the headers, which made the air intake to the turbo slightly clash with the intake manifold. It was okay though because I have a complete silicone intake already which I slightly manipulated.
The pipe for the cooler was obviously different, I used a specific process west one. this matched up well with my existing process west tmic.
I made a braided line up for the turbo oil feed and connected it directly behind the pressure switch at the front of the block and I just capped the old feed. the turbo and right hand intake OCV solenoid shared the same oil feed, which wasnt a problem with the vf38. But the 18G is a ball bearing turbo and my the theory is that the oil would flow through the easiest course, so I moved it to prevent an issue of starving the OCV. I'm not going to say that it was necessary, but it was just a precaution I took.
The turbo flange is different on the 18G than the vf38, so the dump pipe had to be different. I used a Invidia turbo back exhaust system anyway, so the flange matched. I did have to modify the "bolt on" dump pipe though, i dont think this was related to the 18G turbo though. I think the "aus spec" dump pipe that was meant to be "bolt on" was just plain wrong, nothing lined up on the horizontal with the gearbox. I had to cut, extend and change the offset to a more aggressive angle.
So that's my story.
