Great job putting this together.

So few interesting builds going on right now.
I think you're making believers out of your skeptics!

Sorry for the snapchat video. I was too lazy to record another one.

The turbo's knock a lot of the dB's down.

Truth, I remember when I started my focus ST with just the down pipe it was super quiet.

Thank you guys! I will be sticking with this exhaust for a bit until I can afford doing a GT-R style exhaust.

I have the whole driver side wrapped up except connecting the BOVs to the manifold.
I was wondering if it's possible to just tap the brake booster hose instead of having to drill the manifold? If anybody knows let me know please!

Only thing left aside from BOVs/installing the fuel pump is this. I just need to connect them together. I think I'm too lazy to figure it out slowly so I'll just have the shop do it Monday for me.

There is a vacuum port for the EVAP system right behind each throttle body flange on the intake manifold. On each side is a short 90 degree vacuum hose connecting the EVAP pipe to just behind the throttle flange. I remove the 90 degree hose and install a T fitting with a couple 1" long sections of hose. The straight run leg of the T left open, I send to each BOV. Years of testing, works perfect.

Thank you so much! I ordered the T fittings and they should be here Monday!

Only major thing to do is to install the 340 fuel pump and the wiring kit bought from you

I agree! Thank you phunk for this idea as it saved me a lot time

Still waiting for the tuner. He tunes GTRs and his license didn't work for my Z so he has to buy the 370z license. Hoping that happens ASAP so I can drive the darn car!

I just wanted to post this separately. I've been struggling with the steering rack spacers as doing it like GTM makes it so one of the downpipe bolts wouldn't fit due to the tiny clearance left.

I've discovered that Fast Intention's kit also uses rack spacers, but they are at an angle so there's more clearance for the turbos. Obviously they aren't willing to just give me these spacers so i have to figure it out for myself.

The problem is, the rack doesn't like being angled at all. (It either going on straight or angled the wrong way)

I could technically finish using the regular flat spacers but then i would have one missing bolt on the driver downpipe and i don't like doing things halfassed.

Does anybody have any ideas? Thanks guys.

husam2012 · 06-22-2017, 12:26 PM

Been busy with life but i'm almost done with the fuel pump. Should be finished tonight along with the inlets.

Only thing left is to find a permanent solution to the steering rack (Fast intentions gave me the basic idea which actually solves my problem) but they weren't willing to give any details or sell it for me.. So i will have to make it myself. I could actually tune the car as is since the downpipe doesn't leak when it's missing 1 bolt but i don't want to leave it like that.

Another exhaust video for you guys! The tone actually changed somehow and now i love how it sounds.

Jayhovah · 06-22-2017, 12:42 PM

Getting close man!!! Bummer that FI wouldn't sell you their spacers...
I agree it's a good idea to to make sure you get three bolts on the downpipe... don't want it to start leaking when the motor is rocking and rolling.

Is the spacer something you can have machined?
