Christmas in August!!
Well here they are and these are AWESOME!!
if you want to see what gains are to be had for the Z1 headers I would suggest you subscribe to this thread!
while it is a few months out OCT 12 is install date I just wanted to let everyone know how I plan on doing this!
1. the headers are being ceramic coated next week to keep the temps down under the hood.
2.Monday Oct 12 there is going to be a dyno run before install.
list of my current mods on car Stillen Gen3 Berk HFC Ark Exhaust Ported Plenum tuned with UpRev last dyno done when car was tuned 320whp-268tq that was with M370 which is now gone and I have switched over to my ported stock plenum.
3.dyno run with new Z1 headers and HFC for baseline..
4.GoodBye uprev Hello ECUTEK im switching over to ECUTEK for hopefully more power..

 

subscribed.. always wondered what differences if any were to be had with this setup...
not sure if im diggin the bends on the z1 headers.. doesnt appear from these pics to be smooth

 

Seem pretty nice.

With all your mods, you should have of of the fastest N/A Gs. Theoretically.

Looking forward to the install/tune/dynos.

 

Pics don't do these justice they are smooth as can be!! Here is what I'm guessing..switching over to my ported plenum headers and ecutek.. Im Going big here and saying I'll be close to the 345whp..2 months and we will see..wish I could do it sooner but work has been super busy and that's the soonest I can get down there

 

Sub for results. Betting number is 345hp.

 

In for results I'm trying SO hard to wait to but these , I wanna see if there worth the $1300 it'll cost.

 

1300 LOL i wish the cost was 1300.
by the time i get done the total cost will be more like 2450
they are going to get ceramic coated next week.
plus i bought 2 new oxygen sensors since the ones that are usually in the headers are froze..
here is a cost break down to keep in mind.
headers and hfc 1300
ceramic coating 200
oxygen sensors 250
install 700
not cheap but hope that are worth the cost.

 

$700 install labor? Wow. The extra o2 sensors yes. Are you gonna be there for installation? Want more info on where the header meets the steering column.

 

$$2400!! YIKES, I have the HFC's already so It would just be the what$850 they cost plus 300-400$ install. Price I have already

 

Chuckie do you have a X or are you RWD? Details would be good. I wanted headers for a long time. All my inquiries here have resulted in they are a waste of money. I hope you prove them wrong. I would jump on headers if the gains are worth it. I'm sure those of us that are tuned would need to get re-tuned though.

 

i am RWD..all the threads i read about headers are of bashing them on you don't get any gains from headers.i have found very few before or after dyno's on either..but this is where i go and get my car turned and worked on and there are a few before and after dyno's of both...
the few i have talked about Z1 headers that actually had them in the 370z forums one saw a 15whp gain from them..
that is why i am doing to to prove if they make power or not..

here are some long tubes installed by Seb and a dyno run..long tubes picked up great mid range but 0 on the top end..

Stillen headers installed in a sedan with nothing else.. so their's proof that they can make power.

you're HFC wont work unless you change the flange.. they use DE flanges from the 350z..
i am running berk HFC now but will sell them when i switch over to the headers

 

yes ill be there for the install Seb says they are more then likely a all day job..
i will update though out the day when i'm there and get pictures if i can as well

 

roughly 160 per whp if it does come out to be a gain of 15whp..
wonder what the net is for goin FI.. of course I realize the 15whp is just headers.. but still seems high
not lookin to start a debate here.. just wonderin since im still tryin to see what path to go.. NA or FI..

 

It's more expensive to go fi if you are automatic vs 6mt.boost is always fun if you can afford it. I can't justify spending 6k+ on stillen supercharger to live with a 420 whp cap and I also can't justify a 10k TT kit. I'd rather buy another car with that money. In my defense, I'm staying na for that specific reason. If you are 7at or even 5at. The transmission will be needed to be rebuilt for approximately the same 5-10k. .. if u can pay to play then go boost.
