That's a good combo, but to be honest I go back and forth with cold air intakes/short ram/etc. Sure with the hood open or a great air source they can add a bit of hp, but with the hood closed, in theory they can rob power or give you 0 gain.

The cams, exhaust, pipes (or better yet hi flow cats), and Utec are all a good choice.. You'll need the utec and a good tune once you have everything on.. It's a great piggyback system.. Not sure if/when it's available for the 07... But I can find out..

I'm going in the same direction really.. I may put the pop chargers on, but I'd personally just see what happens, I know intensepower has a beta cold air intake system they are working on, so does nismo...

And you didn't hear this from me, but Nismo techs have already installed 2 Cold air intakes (just put the 07 maf in the 06 adapter (fits the same).. and it runs fine without any CEL, but they haven't dyno'd yet..

 

^^ where is your source for that Nismo info.?

 

2 friends that are helping me along with CAI fabrication who work for Nissan/Nismo...

 

do you have an auto or manual?

 

It cant be all that difficult. I would love to look at one up close and see what I could come up with! i just really want to see if they are going to respond to mods well, or if they are just all tuned out!

 

I remember reading (I believe from Sharif) that the UR crank pulley that's out for the pre-07 cars will not work on the 07. More waiting...

 

They come factory tuned pretty well, when the stock 07 kills a bolt-on 03-06 it's not doing too bad.. I'm sure some sort of air induction would yield a 5-10whp gain if done properly... there's no need to change out the headers on this car, though things like the cats/pipes and exhaust really are key.. that and good engine management seeing as how the Nissan ECU is so finicky.

 

did u put in the cats yet? if not, can u take some pictures of collector inside the headers since u'll have the cats off, i'd be intresting to see

thanks

 

Read my other posts (warning to 07 owners)... the cat's flanges don't fit.. it's a waiting game or a custom job right now...

 

so no pics???

 

Sorry but they went right back to Jeff @ WCN. There's a thread link here that shows the difference from Forged performance.

TQ seems low IMO

 

my '06 hits between 150-155 in fifth....with the extra 500 RPM's, I think it'd go past 160 without the limiter

 

Trust me... a clutch job for a Z is NOT hard. You want hard... go change an Evo's clutch. Like bacalhau said, it just takes a bit of patience... and some plastic baggies, a marker, the RIGHT tools and a good memory.

I'd like to see what it takes to get the HR over the 300whp mark.

 

Yeah I'm getting some Turbo XS test pipes installed at Performance Factory (Audible Mayhem's shop) and he already knows there will need to be a custom welding job to install them as the flanges dont match on the header side. Can't wait for before and after dynos.

 

I cant wait to see the difference as well.

Yea, bboy, I was going to change the clutch on my EVO, the write up on EVOm was really good! It wouldnt have made the actual install any easier though. Pulling out that center diff. looked like a pain in the a**!

 

i got my 07 dyno at school and in my 5th gear i hit max 267.33 hp and 263.96 max tq and my 4th gear was 245 max hp and 235.01 max tq i did three runs cuz the first run got messed up when the tach fell off off we had no speed limiter on ours i pinned the mpg gauge at 160 in 5th gear will try to post up the chart soon

 

What kind of dyno and what correction factor? No way your stock Z is putting down nearly as much TQ as HP...

 

holy crap ure making almost as much as mine with my mods. nice numbers

 

He musta hit the 6 key instead of the 3.
