Thinking 13:1 compression
Jun Exhaust Cams
Ti Valve upgrade along with a port and polish

I bet I could make 350 with just the cams.

From what I hear there have been no issues with the TT kit as long as the boost is not set too high...

Are you referring to SC kits? TT's use there own turbo manifolds. You can't use headers with them. Or you talking about something totally different?

Spohn, what does your exhaust note sound like? Any rasp?

Anyone know if there are good resonated hfc/tp for the 350 that could eliminate rasp with this setup and a non resonated exhaust ?

SPOHN · 12-13-2012, 09:24 AM

There is rasp. But I always get told how great my car sounds. Always! But sitting inside of it can be a hole different story. But I love it. I'm not picky as most people here are. I'll try and get another sound clip up today when I get off work.

this is what they sound like inside the car with straight pipes and two glasspacks.

As you requested, sound clips. Sorry for the shaking camara. First 30+ sec. are cold startup and the second bit is revving.

Myron_Nismo · 12-13-2012, 04:15 PM

^nice!! Doesn't sound that raspy IMO. Definitely not like a civic or anything. Sounds mean

How much are these? How much do places typically charge for install?

You will need Z1 test pipes also. Call them for best pricing. To install can be costly also. Headers take some time. I'd guess about 7+ hours. Then a tune after.

I'm just glad I do all my own work. But I've done this several times. I know our cars pretty well.

Sound awesome, congrats.

Why are the test pipes needed? Were these headers designed for the 350Z?

djtodd · 12-14-2012, 11:51 AM

yep

Yes. The flanges are different.
