[@ICT.350Z]

It does give a power advantage, but perhaps also a change in the curve. Takes a good few hours, even a couple days for the ECU to adjust and compensate.

[@AnthonyJ350]

I'm interested to see if the midrange fattens up a bit. Torque still doesn't come on till about 2,800 rpm

[@DadeBoi_Czer]

Had my 75mm for bout a year and it’s awesome 🎉 totally complements my cold air intake system from Z1 my bigger Plenum from kinetics and man 😊love it

[@AnthonyJ350]

Thanks for sharing your experience!

[@benny6712]

Yup, this setup makes a bigger difference with the 3” intake pipe from the filter back

[@robertmedina6875]

You're welcome, and thanks for watching!

I’ve had mine about a year now and it’s one of those mods that you instantly feel the difference! 🔥

Totally agree!

[@kmk1195]

do you need a tune to run it?

[@jewllake]

I put a simple ported and polished kaytech TB on my 2018 6.2 Sierra. It eliminated a slight hiccup I had under light throttle acceleration.

[@AnthonyJ350]

That's interesting. Hope you're doing well!

[@stealthg35infiniti94]

I agree, if you want the Maximum Benefit from a 75mm Throttle Body, the throat of the upper plenum must be enlarged. Otherwise you will get the same effect as 70mm at WOT. The exception would be Forced Induction.

[@AnthonyJ350]

It offsets the volume the butterfly valve occupies in theory.

[@stealthg35infiniti94]

@@AnthonyJ350 I agree.

[@mikewaite3746]

It seems like you really do know your stuff about cars. Love some of your bantering back and forth with Anthony. I had a little bit of bantering back and forth with the engine wire harness cover.

Between our experiences, we can disspell most myths/exaggerations/false claims. Don't believe everything you hear. Go to independent experts that have nothing to gain.

[@neterosrose]

Love your vids brother, quick question tho. Can I run a plenum spacer and the V+ Kinetix Plenum simultaneously without modifying anything? The black one that you did a heat comparison video for with that G35 a while back.

[@AnthonyJ350]

I think you would run into clearance issues. I would chose one or the other. In theory it might pick up a lot of top end but might lose in the bottom and down low. I'm just speculating, I've never seen the combo done.

[@larrycampbell6133]

I had that same exact question and haven’t found anyone that’s tried them together. The hood clearance was my primary concern. And if I had to choose one or the other, AND never planning on going turbo - I’d probably just get the spacer. But that’s just kinda going off of what I’ve seen other people do

[@TheGamerJalen]

Can you do the high coils packs next from z1 motor sports.

[@AnthonyJ350]

That's something we can definitely look into.

[@maqsoodnsx]

We need to do an idle air re-learn

[@AnthonyJ350]

Not a bad idea to do an ECU reset and take for a long drive

[@freeyourmind8849]

Nice video. I wouldn't recommend larger TB unless your using forced induction. Never by a TB spacer is snake oil. The heads and lower intake manifold flow well. Just the front cylinders stare for air under WOT so porting or use a spacer helps.

[@AnthonyJ350]

Even if you're trying to compensate for the volume the butterfly valve takes up and trying to squeeze everything you can out of the engine from a bolt on perspective?

[@Michael-ty2uo]

Most people get bolt ones like this to support their upcoming forces induction kit. Or they know it’s not going to provide an insane amount of horsepower they just want a small bump

[@dylan2g]

nicee aree you going to get a re tune?

[@AnthonyJ350]

Yup I plan to, because of all the changes we've made.

[@ninobulfa]

Do I need tune if I install one? Or its okay for ecu to relearn and continue to use it daily? I am in vegas and I dont have access to a tuner for z.

[@AnthonyJ350]

You should be able just to do the ECU reset and take it for a long drive.

[@leakyjeep5.9]

I wonder if this would benefit a 6spd Maxima with NWP spacers and a vias delete.

[@AnthonyJ350]

If you have other intake and exhaust mods it will.

[@vjf3337]

Do you have the throttle body relearn procedure my car been acting up time to time and I believe I need to do the relearn more times …… could you plz give me steps if you know?

Hi Anthony, seeing as you are the go too guy for the Nissan 350z cars, could you help me out please, I need to get a new/used ECU for my 2001 350z and I'm wondering if they are like BMW, where you have to have the VIN number changed to your original vin in the ECU before it will work, do you know if the 350z ECU stores the vin number? Cheers

[@AnthonyJ350]

2001 350Z? Check the VIN to verify the year. Also see if Z1 Motorsports has any ECUs available.

[@JohnSmith-wb6kq]

@@AnthonyJ350 Thanks for the reply, Sorry mate it's a 2002 (fat fingers) model, I have a second hand ecu here for the car, (down in New Zealand but not sure if you have to write the original vin into ecu, I had to have it done to a BMW a few years ago, does Nissan store the vin number in the ecu?

[@AnthonyJ350]

@@JohnSmith-wb6kq That I'm not sure, I've only had my car dyno tuned. I haven't done an ECU swap on this chassis.

Will you be going back to the dyno to adjust the tune?

[@AnthonyJ350]

Yes definitely, want to make sure everything is correct.

Does anyone know if this mod will still be able to pass smog check as everything else is completely stock and cat are still on.

I see no issues, provided there's no check engine light after. Make sure to do the relearn procedure and drive the vehicle. kzbin.info/www/bejne/a6W0nmVugJhlibMsi=ZCsHif9uof6FIyQD

[@user-dd8hj3ls9d]

By any chance is your tube sitting on a coil pack as in the hose under got any clearance issue since for some reason mine just lays on a coil…

@@AnthonyJ350 yeah after watching your video I did greatly appreciated no more issue I just didn’t turn it enough because the tube would pop off so after leaving it overnight the tube expanded so easy to fix thank you

[@Vonie2Geeked]

Would this work with the the rev9 turbo kit ?

[@AnthonyJ350]

I would contact the manufacturer on that one.

[@littlez3325]

Is this basically the same for HR?

[@AnthonyJ350]

HR has 2 throttle bodies and uses valve timing to do everything.

[@autoperformance503]

I have a 350z while driving car stalls no engine light ?

Use the clutch better?

[@sportsmansparadice42]

Did you loose any low speed torque?

Didn't notice and the dyno graph showed peak torque coming on the same way at the same RPM. If anything the low end felt a little better.
