what next? headers?

370Z JT

I know meganZ had bored throttle bodies and saw nice gains. I believe 7-9WHP?

9whp being the max seen.

but there is more than just boring out to 62.5mm
the shaft was cut in half and the arrow edged the butterfly plate

im pretty sure there is a picture in one of my album here.

edit; to see the true power potential of this mod , the intake tube,specificaly the MAF tube has to be bigger than stock to maximize the Hp gain.
the OEM MAF tube size is 60mm with the big MAF sensor in there so there is a restriction ,,, the MAF section has to be able to flow more than what it is at the TB to see the result.

ok I was looking at headers and was wondering kind of what has been touched on here. I'm running stillen gen3's and exhaust ,so I was thinking stillens HFC and headers was also a good route? I want to stay legal as this is my daily driver so does that mean LTH are out of the question?

Yes LTH are out as well as TPs. You need a cat to be able to pass smog if they smog test in your state

I'm surprised at how much people do headers compared to the previous VQ motor. Most could not justify cost and installation for the gains. Is the gains that much better than the DE motor?

SPOHN

Yes it is. I've seen three cases where they are, so I went this route to. I had no luck with headers on my DE motor before. But with the Momentum headers and the way there designed with the collectors inside makes them better than most. So when combined with our new motors it just works.

I bought the same headers along with 350z Berk TP's. SPOHN, I'm assuming you are going to do the install yourself? I'm not sure I'm brave enough to tackle this since I'm in a corporate apartment complex... however since I'm in Texas, UPREV is right down the road so I may see what they'll charge with install and a tune

Sure am. Tomorrow. It's the third time I've done it so I know a lot of tricks and certain tools to help a lot. Course being the radiator core support is off it's a lot easier. The stock manifolds are off already so I just have to slap these on.

Not really. I smell raw fumes when at ideal or coming to a stop when windows are down. But I love that. I guess you could run HFC from a 350 but dont remotely expect the gains.
Yes.

I know TPs would be better but would HFCs really be that bad? Would momentums not even be worth it at that point? Not trying to argue but I really just don't have to much knowledge on the subject

It wouldn't be that bad at all just a little less. There's a lot to gain from these headers from what I've seen so they would be worth it.
