Hi cost to fit, round 6 to 8 hours

needs tune to get the most out, Will help though to get the most out of the tune

may be LHD, hard to fit with RHD

 

 

Stay tuned for my update!!

 

Tasty stuff. Are you buying them or have you already got some?

 

 

these 5zigens look a bit smarter...

Not the nismos, but fujitsubo ones :teeth:

 

Envy have that 5zigen set in stock, PM sarah or Gaz for a good deal ;)

Nah, not for me, I don't much care about what it looks like under the bonnet (I had an Alfa v6 and after that no engine looks good). I`m banking on a cheaper ECU reprogramme for a few more lb/ft

 

You cant see them! ;) They are more for flow reasons... Stock ones are 3 unequal lengths, aftermeerkat ones are 3 equal, any tuner / reprog should be telling you this is one of the major holdups and are worth changing to prior to flash / chip!

 

BTW you still got any wtee on your car?

So no torque loss with all that free-flowing?

wtee??

wtee??

 

Nope, non if you are getting it mapped etc

 

wtee = warantee..

Just to add....

 

Q: Does my exhaust need some backpressure to work properly or make more power in a N/A application?

 

A: HELL NO!! This is a myth. High exhaust velocity is good, backpressure is bad. The way to achieve high exhaust velocity is by picking the correct sized exhaust for N/A. If your exhaust is too small, it will create backpressure. If your exhaust is too big, the exhaust gas velocity will be too slow. That is why people do not drive around with 4" exhausts for N/A.

Might lead to it running on the lean side though. Nothing a remap wouldnt sort out though I hope ;)

 

Point is on the remap that it totally invalidates your wtee and any chance of proving them wrong.... unless you can get it back to whoever did the remap and get them to put back your original image... If piggyback then at least you can remove PDQ and everything looks "normal" on the ECU side... that was my question about any wteee!

Sorry I wasnt refering to anything about which way you were remapping (piggyback or reflash), just meant that on OEM it might start to push it lean.

 

WRT a reflash and it invalidating your warentee, they (Nissan) would be hard pushed to tell its been done if you use multiple maps and switch it back to normal map when its in the garage. I've seen it loads of times with the SEAT with a seperate map, they cant tell its on there. All their stuff behaves as it did before. They would physically have to HEX dump the ECU firmware to prove its been modified.

Me thinks that you may be thinking that the Nissan 350z ecu has the power to hold more than one map.... :wacko: perhaps it will suprise us!

 

And yes, agree that if you dont remap then you may have an issue on stock...

Its on the UpRev site. Cars with cruise control can use the controls to switch between multiple maps when used with their reflash. According to RSTuning its the same ECU as a Renault (makes sense given they use the engine too) and seeing the remaps possible on them, I dont see multiple maps being a problem. You dont need more power for multiple maps, just more space on the ECU memory to store them ;)

I thought that was only on the JDM's or USD cars though wasnt it?

wouldn't a Haltech sort out this issue. disconnect it before heading to the stealers and your back on OEM ECU?

 

does ceramic headers offer superior performance to stainless steel ones (putting heat resistance issues aside)?

 

which headers have 3 equal length pipes and which ones dont?

 

I also noticed some companies on ebay US offer a complete system from headers to back box for reasonable money, although I never heard of the brands, its seems interesting to say the least.

 

 

it would also be interesting to see how you get on with fitting LHD headers versions on your UK car. keep us posted :thumbs:

Haltech yes, but costly and there are other options :) Haltech / HKS vcon good if your going FI. And yes, they are easy to turn off but because of the mods your car prob wont be running too well!

I think ceramics are better, remember reading about them on a forum somewhere

Most if not all are based on equal

Are we talking longtube manifolds (headers)? got any links? The best are pricy, and more expensive than standard to cat ones... I wouldnt as you get rid of the cats and come MOT your looking at a lot of cash to put the cats back in!

Am fitting RHD japanese manifolds so am sure they will be fine! But will update you :)

these are ceramic coated

this one is interesting as it claims long tube headers are better than short tube ones :wacko:

this is the full works

I know we are talking about fleabay but the concept is interesting in principle

Noooooo dont say that! Got any links where they confirm it? :cry:
