512_z, you said you had to upgrade injectors, how much of a restriction were the stock ones?

 

I have a long tube headers, but I must extended the A/F (drive and passenger) sensor to install. What type of A/F sensor extension can I buy?

Sub'd for more DE dynos. I've read through this entire thread just now and I am still not 100% clear on what the benefits/advantages are over stepped/non and reducer/no reducer. I have a non-revup, that is a track car only. A road racing track car; not drag. So anything under 4k RPM's means nothing to me.

I would be looking to make mostly top end power and mid/high end torque.

Would I go with non-stepped with reducer? I have MD XYZ pipe and 3" single shockwave.

Thanks

 

Is not the same connector that I have in my pre cat sensor. The connector have 6 pin like this: http://www.autopartsnetwork.com/cata...r_make:Nissan_
I need a female - male cable to extend this sensor.

Excuse for my language, but I'm from Italy

 

Just installed mine over the Thanksgiving break. Loving em so far.

They're dumping into the stock y pipe flanges (kept them in my custon 2.25in exhaust) no doubt its raspier than it should be. Ordered a 2.5in muffled x pipe to replace my current one. Trying to anticipate if I'll need some down stream resonators.

Once I get my exhaust straightened out I'll be getting dyno tuned @ Z1. My before from Z Nationals was 231/224.

 

Anyone want a set? I have a set for the 06 DE Revup that are Non Stepped, Coated, and don't have a reducer. I'm never going to get around to installing these...

 

Could someone do a sound test with their exhausts and see if the decibels ever increase past 94db from 50 feet or so away? SCCA and some tracks restrict the noise levels to that. I really want these, but need to be sure before I buy! That is the reason I didn't originally sign up for the inital run.
Thanks!

 

How much ? Pm me

 

It depends on your setup. If you have the oem cats or hfc its definitely going to be louder.

 

What's the overall consensus of these on DE again? Terras?

Also what y pipe are you guys getting to match up good?

 

^ To second that, has anyone retuned and dynoed vs hfc/test pipe by comparison of gains? overall and delta?

 

I wish I could do that comparison but I'm afraid of negative results.

 

Same car as above, pretty sure we should have stepped

 

Feels good, no dyno yet. Finally got my wideband up and running, I am running lean and need some tuning work.

 

Unless you run Lime Rock, your closest db restraint will be 99db at 50'. Last time I checked as long as you didn't go over 106 summit and VIR is about the same. That said, my car with Tomei shorties, test pipes, and nismo style exhaust consistently blows 97-99db (depending on weather) at 50' during national events.

 

Thanks man! We will get these soon enough

 

first drive impression....



video pending!

 

WTF is taking you guys so long to get good vids

im about to shoot myself

 

I wish I knew what this thread was about
