Wouldn't have believed it if you hadn't posted the photo. Seeing it as it was at 2.30 and you were heading out to what it was like 4 hours later is unbelievable

Awesome work

I'm pretty stoked with them, For me its a huge milestone since i started the design of this system about 5 years ago.

To many its just a set of pipes but nobody has made a proper set of equal length headers for one of these that go around the back of the motor like mine do.

I have just ordered some 2" flexi bellows so i can finalist the crossover and turbo feed pipe.

For the mean time i need to do things like

Make a new mounting position for the coil
Do something creative with the dipstick
Thread tap the catch cans to BSP
Make a nice single piece bracket for the catch cans
Make up the push lock lines now that i have the correct mounting position for the catch tanks.
Buy some M6 threaded rod to make new bolts for the V bands.

And for good reason too! they're pretty sweet. Not quite as sweet as mine but pretty close. Adding points for making them yourslef also.
Are you going to coat them with any heat repellant?

How come you have to tap the catch cans from 3/8 NPT to BSP

Oh because I'm using JIC / Pushlock fittings the adaptors are for BSP to JIC - so its just convenient to throw a BSP tap through it and I don't need a mixture of fittings
