Z1 smooth tubes worth it?

LakeShow · 03-15-2012, 01:15 AM

I think it's something you feel as the responsiveness of the car rather than numbers on paper or computer.

Maybe others have had better luck then I did with this setup.

Other mods to the car? Dyno chart please?

Did you remove the negative battery terminal and reset the ECU? Or get a tune afterwards?

The ECU bases WOT response on closed loop look-up tables + MAF input in every other car I have owned. This wouldn't effect that.

Even if it did, after a certain number of key on/off engine on/off cycles, it should adapt, no?

I gave up on making mine fit also. Plus on my Nismo the breather tube on the driver side is different than the passenger side but on the tubes they are set up the passenger side way, if that makes sense. Just stuck my K&N drop-ins, in and called it good. I Get my Fast Intentions exhaust tomorrow tho

I get my FI exhaust tomorrow, too!
I did finally get the tubes to fit - had to trim about an 1/8th of an inch off the passenger side. There is a noticeable difference in throttle response. A lot more than I would have ever though possible just going from the corrugated tubes to smooth tubes.

The ribs tend not to be on the inside.

Ya I know, way to dig up an old thread but was wondering about the oem intake tubes myself. Installed Z1 post maf tubes today and the oem ones ARE ribbed on the inside. For her pleasure. Made me feel better dropping a hundred bucks on these knowing they are smooth vs stock ribbed.

I think it's worth it. Makes it a little cleaner under the hood. Put the air box side on first. It's a bit of a wrestle, but they will fit. I did not have to cut them. For a little help, you can get some cheese & crackers & use the red plastic spreader to help get them onto the throttle body without marring them.

Hey Tony, I'll swing by in a couple of weeks & you can see mine if you want. A little busy right now, so it will be a couple of weeks.

Put red Z1 tubes in this morning along with drop ins and the fang vent mod. I must've gotten a good set or something cause my tubes went on no problem (I did remove the strut brace and air boxes before installing, though). I've only had the car a week so idk if i could really distinguish a hp gain, but it definitely revs faster. Overall totally worth it imo

they arent that hard to install. People need to quite whining, These things are strong and not meant to bend alot, so yeah it might be a lil tough to get it on, but if i can do it (and im a weak mother fucker) all of you can also. Want to do it without much effort, pop the who intake off and do it that way.
