Anyone else understand that?

Say what? :icon14:

Well just went to the dyno Saturday and made 300 WHP 233 wtrq 7spd auto
Untuned X coupe .
Mods FI RHFC'S
Takeda longtubes
Exoticspeed cat back .

306.7 SAE WHP
253.2 SAE Ft/Lbs Torque

Mods
-Stillen G3 Intakes
-Z1 PCV breather hoses
-Stillen UD pulley and belt
-Motordyne ART Pipes
-Fast Intentions SS TDX CBE w/12" resonators
-NGK Iridium Spark plugs

I thinking on buy soon some upgrades to my Z at the moment i want this upgreades:

1- Stillen Gen3 CAI
2- Invidia Gemini CBE
3- Some headers
4- Tune

I put some headers cause i dont know what are the best. I read that Stillen dont work... what headers do you guys recomend me to buy???? that the mod list that i want for the moment. Im going to be more than happy with 300whp for now:) In the future im going to buy the GTM Turbo Kit ;)

Any recomendations are welcome :)
Thanks!!!

Z1motorsports/momentum headers with test pipes are making the highest gains as of now. so those would be on my list... the G3s seem to be making the most power intake wise. CBE is probably motordyne or FI hp wise

if your going with a turbo kit, forget the intakes and save that 500$ toward the turbo kit, same with the headers ($800) thats a good chucnk toward your turbo kit right there. both Motordyne and FI CBE are making 300+ without any other mods. so choose one of those and your "ill be happy with 300" will be met, and save the rest for FI. maybe some K&N drop-ins and post maf tubes will help you peak that as well and is only ~$200 vs 500+ for stillen G3. Good luck hope this helps. :tup:

My friend thanks a lot for your recommendations really helps ;) well im going to start searching where to buy that CBE :) well I think that im going to do that and maybe i think im going to buy the headers cause i think that the GTM Turbo kit have to wait maybe 2 years because im planing to get married and i have to buy a house too looool!!!!:icon14: let see what happen bro!! Thanks a lot!!!

The best long tubes are PPE's. A lot of race teams had these exact same headers. I've written a lot in the past about them if you want to do some searching. The Z1 (Momentums) are the only shorty headers that are worth spending money on. If you plan on going turbo, and stay under 550whp, don't worry about trying to buy a dual 3" exhaust. While it is true Motordyne and Fast Intentions have seen the highest gains, we are talking a few hp difference compared to others. Remember that turbos will act as mufflers too so don't be afraid to go aggressive. With the headers though, if you do get Fast Intentions, opt for the 12" at a minimum if you don't want rasp. The Motordyne exhaust should be good. be aware that header will change the pitch of your exhaust to something higher. It will SCREAM. Shovelman has vids with PPEs and fast intentions with no resonators. I have mine mated to a Tanabe exhaust and a HFC in the Y pipe. You'll notice even with completely different exhausts, you can hear similarities because we run the same headers.

The intakes imo, again they are within a few hp of eachother, especially after everything is tuned. I personally like the AAM intake design. They have a sleeve you can insert or remove to adjust the pipe size at the MAF. Once you go to get the car tuned, just remove the sleeve. As mentioned above the Stillens actually have a good rep for their intakes.

I have vids and dynos in my journal. Some newer vids are in the last few pages. Best of luck, it's like Russian roulette when trying to figure out what your exhaust will sound like when you add headers.

Thanks a lot again bro!!! you are help me a lot in this thread and the Forced Induction Thread ;) well im going to check out those parts... the only thing that i know for now is that im going to build my car first in N/A and in the future im going with a Turbo kit hahaha!! if i win the lottery of course im going turbo for sure hahaa!!! For now i want some power ;)

Thanks guys or the help!!!

There was a post on Zatlantas facebook. A nismo made 357whp with e85 and 346 on pump. Apparently Z1 and TSM is starting to put GTR injectors and a fuel pump.

What dyno/correction factor? The gain of e85 is nice but 346 seems awfully generous!

Yeahhhh... that's pretty high.

This time I'm going to be the one to say "impossible".

want to know the mods..... have to be interesting

Not on Z1's dyno. Theirs is very optimistic. Helps to sell parts to have one that reads on the high side. ;)

note to self: dyno my car at Z1 next time.
