Header mod or no?

Honestly any more mods past what you have aren't worth it. I wouldn't spend more money on anything but injectors to run E85 if you have that available locally. You can probably make 320whp on E85 with a good tune w/ your current mods. Going from 320whp to 350whp will cost you as much as FI and it will still be slow.

Staying naturally aspirated will cost you a small fortune and is not worth to most. I would not do anything else past what you have done to your Z already. Save up for forced induction and go that route if you really want more. Nitrous oxide is one of the best bangs for the buck and can be safe to use. I would go with nitrous kit on your Z!

A lot of us ask ourselves this same question at one time or another.

that sounds like a quitter mentality

I thought the same until I did the common mods (HFC, intake/exhaust, tune) AND bigger rear end (gears) and it's definitely worth it! Shut up with your generalizing suggestions!

Interesting, I'm NOT on e85 and its on UpRev making... look at my sig.
I'm not even looking at E85 options until I go boosted.

If I add the M370 intake mani and retune on Ecutek, 335+whp should be doable with my Tuner.. again, without E85.

It's because you guys already have the good gas (93? 95?)

Over here in california, we have watered down gas. So E85 will be felt more for us

Yeah, good point that's true. Cali has 91oct so I guess in Cali upgrading to E85 would be beneficial.

93oct here btw.

btw from the videos and reading i've done, headers with tune will add on avg +15whp and similar torque.
