I haven't seen anyone with the ZDX throttle body yet, but had I known it was cheaper and was compatible I would've 100% bought it instead. I would've saved $200. That could've went towards my new intake lol.

Let us know how you make out fenda. Definitely excited to see some more people do this swap. And I agree with ANX, definitely do ported/polished runners as well. With that said, you may want to gasket match the new manifold to the OEM gasket since the ports are ~1mm smaller (I believe they were 43mm when I measured the lower TL ports). The gasket matched PERFECTLY with my polished runners, so now the transition from IM to lower runners is smooth as glass.

Seriously, $200 is a good chunk o' change! What is your intake set-up gonna look like? And thanks for the heads-up on gasket-matching the ports...I guess a nice Dremel job should do the trick?? I'll definitely keep y'all posted when I pull the trigger! It may just be tonite!

Sonnick

I'm not sure what I'm gonna do with the intake yet. I think I'm going to use AIRAID. Someone linked me on V*6*P and it seemed pretty legit. Still undecided on whether I'm doing 3.5" or 4". I'd rather not have to squeeze the piping/filter in for the 4", but I do want the most power...not sure yet. I'm assuming a larger intake will make at least another 5-7whp on my setup.

go to 4 inch !!!!!!

I should be getting the 2012 Tl-sh Awd and 2012 rdx tb this week. I'll see how it goes

Still don't see this as being a good idea unless someone can prove otherwise. I just see excess turbulence when the intake is considerably larger than the TB opening, thus slowing intake air velocity. It'd be a different story if we were dealing with a 100 mm TB. Excess turbulence is what causes VQ cars to lose power with an aftermarket intake. I think the TL might escape this issue though since it's speed density rather than MAF, but bigger still isn't necessarily better. 3.5 should be ideal.

Hi!

I have not played with manifolds/TBs on TL but I have a quick question, would a zdx tb fits a oem type-s manifold bored to 70mm? Any pros or cons of doing this?

hondazex

iTrader: (1)

not fits dom !!! only with 3,7 manifold !!! or adapter

DomGSR-T

iTrader: (1)

ok! would I loose the runners from the intake doing this then? and will the idle be the same as oem?

pearlUA7

I see recommendations for the ported runners, and what about the manifold (3.7 swap) , sure port match but what about a full port and polish?.... Overkill? I I just ordered my parts and just trying to figure it out.

hondazex

iTrader: (1)

not over when you have full exhaust mods !! after get a fine tune , with your mods hit 300 whp for sure !!

What size coupler is needed for the zdx/shawd TB to work with my CAI? Also, is everyone relocating the IAT on the CAI?

hondazex

iTrader: (1)

3.25 to 3.5 approx and yes iat in cai

Sonnick

I have to assume a 4" will work for these cars. The K series, H series, and even B series have all seen gains going from a 3" intake to a 3.5". I can see the J gaining some power with a 4".

I plan to cut a part of v2, 4 inch starts to the corner 4 inch all the way

iTrader: (5)

^^^ the problem with a 4" intake is that it wont fit through

I know Andy made it fit but cutting the pipe/various bends/couplers and making it fit but i just dont see any metal pipe which will fit as a direct bolton

Sonnick

Hmm. I'll have to ask the guy on V*6*P take some pics. He said the 4" AIRAID tubing fit in his fender. Seems to be a good product. Won't get as hot as the aluminum

iTrader: (5)

^^^ wrap your tool

wrapped alum intake = lower intake temps

Sonnick

Lulz. AIRAID isn't aluminum ftw

pearlUA7

including boring out the already much bigger zdx TB?

pearlUA7

also would a port matched tb spacer be unnecessary with the pnp?

Sonnick

^ I bored out my TL throttle body to 81/72mm. It's definitely worth it. These motors love air and the more you give them, the more power they make.

NVA-V6 is making a dual TB setup that will surely outflow the 3.7 manifold/TB. He hasn't dyno'd it yet, but it looks promising, especially for the 3.5-3.7 guys.

I would skip the spacer when doing the 3.7 setup. It's never really been proven to do anything.

^^^ THIS

now i feel like an idiot arguing with IHC about it

Damn I would have love to see a sae CORRECTED dyno of before and after

Sonnick

^ That's exactly what my dyno shows. Both runs were SAE Corrected.

anx1300c

iTrader: (2)

That is SAE corrected. If it were uncorrected, it would read "uncorrected" where it reads "SAE Smoothing".

JL-TL_07

Hey guys, I was wondering if this mod of the 3.7 (intake manifold and throttle body swap) is compatible with.the 3.2?

DomGSR-T

iTrader: (1)

From all the runs I made on winpep software dynos since 1998, the applied sae correction factor was marked at the end of the run names like on my last runs with latest winpep 7 software:

http://i1108.photobucket.com/albums/h405/DomGSR-T/DynoTL-SPart2.jpg

Smoothing lets you to show six different levels of
detail in the graph. Level zero shows the most detail
while level five shows the least detail. Level three is
the default setting. (-----taken from winpep pdf.

So maybe there's a way to show or not the temp/humidity/pressure/sae correction in the run names. That must be why it don't shows on your dyno. I just thought all winpep7 were the same.

Sonnick

If you're talking about CF, I have that as well at the bottom of my sheet. My pic didn't get it. I can post it if you'd like, I believe the 'before' run was .96 and the 'after' run was 1.03. It was much hotter and humid for the after run, hence the CF. it was something like 65 degrees with minimal humidity compared to mid 90s and 40% humidity.

oh ok! no I did not see the bottom of the page so sorry about my post then

iTrader: (1)

yes, same shit.
everything in this thread applies to everyone that has a 3rd gen TL.

Sonnick

Not sure why the same question (answered more than once already in this thread) keeps popping up. Thankfully there wasn't another thread started about it, but jeez....does anyone do research on their own anymore? I loved researching about the Venturi collector when I was doing my exhaust, and keep doing research with each part. It's part of the fun!

^lol why do you think IHC's doesnt post in the performance section any more!?!?!??!?!?!

lol because PEOPLE SUCK and dont know how to read.
Butt, i bet they'll read that and get angry at me.

*edit
I do thank you, Sonnick as I've learned a lot from you.
keep up the good work and push for 300 on that little 3.0!

pearlUA7

.... sooooo does this fit the 3.2?

pearlUA7

but seriously now, 3 and a half years ago racinghart03 installed and removed, said it wasn't worth it. that was over three years ago and the parts werent on for longer than a day. im already committed to this swap but just want to know which one is it, worth it or not. there are talks back then bout losing too much at the bottom, talks now how a full 3.7 pnp along with runners and a bored out tb is way to go. i leaning towards goin all out but am still conflicted with old news. can someone shed some light please. stillhere, justinspace, etc (azine veterans) just a plain yes or no would be fine, 3.7 swap fully modded (ported runners, matched and pnp mani, bored tb)?

Sonnick

Thanks Justin. I've learned from you as well We'll see about that 300......

I concur with mr crabby....i wish people read a little more and not only on this section but also in other parts of the forum....they still create threads with "where do i buy switchbacks" and "whats the best CAI"

Dom, Sonnick is legit he is not a guy who bloats numbers....i trust him
