I made 341whp/271wtq with the following list of power or power related mods:

Z1 Intakes
Z1 Plenum Power Mod
Motordyne LTH
Fast Intentions Exhaust
Stillen Lightweight Pulley
Z1 Lightweight Flywheel

The next round will include the following list of upgrades:

Z1 Race Intakes Upgrade (Installed)
Z1 Ported Lower Intake (Installed)
Dewla Dezign Cold Air Intake Guide (Installed)
Z1 2-piece Lightweight Rotors (Installing this weekend)
Jim Wolf C2 Cams (Pending installation and tune at Dynosty)

I was also going to do EPS Big Bore Throttle Bodies but both Z1 and Dynosty have recommended staying away from them due to poor idle quality and reliability issues.

After the tune is done, I will be going back and upgrading the LSD and final drive to 4.08s. At which point my N/A build should be complete... yea right.

I will share with everyone the results of the C2 cams once completed.

How about an exhaust video. I want to see if this car sounds as good as your old one. LOL Your old car was the best sounding 370z ever. That is why I opted for the Carbon Fiber mufflers on my 3" exhaust.

For all that have never heard it before.

I have had one in the works for awhile now. Hard to say if mine now is better than in the video. The Motordyne Headers w/ Hemholz resonators produce more of a high pitched exotic noise where the setup in the video was a very deep sound. Also my FI exhaust is non-resonated now as opposed to 18" inch resonators in the video. Below is Dynosty's video on facebook of my setup but doesn't do the setup complete justice.

I will try and get a video put together though for my current. The weather is supposed to be nice tomorrow.

How much of a pain was it to install the z1 intake upgrade with the dewla air guide? I was thinking of doing the same, but wasn’t sure there would be room, even with a modified crash bar.

I was worried as well but it was not an issue whatsoever, they do not interfere with each other.

I'm actually running the FI tow bar. I'm not entirely sure how they mounted them when it was reassembled at Z1, but Injust had them resting on the bar. The air guide was bolted in at the top. It screws into the bottom of the stock bar, but that's not an option w/ the FI bar. I used a stainless steel zip tie through the hole in the bottom of the guide and the tow hook hole, pulled it as tight as I could and hit it w/ some black spray paint. It was pretty solid that way, but I imagine Z1 screwed it down a little better.

Nice! Glad to hear the intake upgrade and air guide work together with either the Z1 bar or the tow bar. I may have to add these...

They're a pretty easy mod to do also (the intake upgrades, I can't speak to the air guide).

241 hp?

I have most of the same mods, E85, ported upper & lower, etc..

I have not installed the headers or cams yet...planning on both at same time.

Not optimistic that I can pick up THAT much power with the cam and headers.

But now I am having concerns with my EcuTek tune. Maybe I will goto UpRev...

The guys at Z1 have stated that the newer Zs, 2016+, have consistently been producing higher dyno numbers, both stock and with upgrades. Not sure if that carries any weight or not but will be interesting to see.

Ecutek is fine. You are over thinking this.

I hope you are right, but:

My 50 plus track runs, 20 data log files and three dyno sessions say otherwise..

I’ve built and flywheel dynoed lots of NA motors, some over 1000 hp.

I really think my 370z motor has a bug somewhere...I just need to find it.

What did Z1 and Dynosty mean by poor idle quality and reliability issues? I've been running the EPS TBs for almost 2 years without any issues and I was remotely tuned by Seb.

They didn’t go into a lot of detail other than what I stated in the post above... just that they ve seen issues with them on occasion. I don’t want to believe them because I want to try and squeeze every last hp out of it but the fact they both stated it without me asking when I mentioned installing them has me shying away.
