So what do you recommend Keith? Do we just install both P2R IM gaskets and leave it on or should we use a different gasket underneath where it gets hotter. This will leave the P2R in between the IM and spacer which I think it where it's mostly needed and should withstand the heat.

Any comments on your IM spacer and turbulence? It looks like a damn fine product.

Yeah I wish I knew this before ordering both IM gaskets.

They work. Just dont take your manifold back off. If you do you will prob need another set. Or you just run 2 steel stock gaskets and you can take it off and put it on as much as you want. You will be fine. They are non reusable remember that.

OK, that makes sense. If the gaskets melt, will the bolts need to be tightened again after a certain setting time?

I'm opening up my parts just now and noticed a few things:

1. One of the runner openings is not completely round, it has a slight notch in it:



2. The IM spacer isn't port matched to the IM. Isn't it supposed to be? Here's a picture of the spacer sitting on top on the IM. The IM spacer has a wider opening.



3. All of the parts where air will flow don't appear to be completely clean and free of fine metallic residue. Should I just clean with isopropyl alcohol and proceed?

where did you buy the runenrs from? Here is what mine looks like. Very little of the seam is left. Get a dremel and sand it down some what


as for the spacers. Look at the bolt holes... They aren't even lined up. Line them up correct and they should be mostly match I think.
Clean the parts with brake fluid cleaner. You don't want any those of residue inside of your engine.

^^^ i agree with that azn boi

this is bound to happen when you get parts from 2 different area....am guessing the IM spacer is from KPP which has a 46.xxmm opening and the runners are from Andy which have a 44.xx opening....

The runners are from my car; I sent them to be worked on. Everything else is fine except for one runner opening in the pic. The seam only shows in this one opening.

Even after lining up the IM spacer holes, there is still a difference.

Everything is from MPP.

@ Swoosh Thanks man

@ Hacura its probably a casting issue with the OEM runners since because usually the welds stick outwards. your is sunk in, and I think Ethanol didn't want to overbore it. It happened to a set that I was finishing up a few mins ago. I just couldn't get it flushed cuz there were really bad casting imprefection which also caused it to sink inwards. But its not as bad as yours.

Ahh, that makes perfect sense. I'll clean up the little notch and clean everything with brake cleaner before installing.

Thanks for the help bud.

Yes that tube casting was pretty bad. Your runners had a lot of casting issues. The spacer is overbored for a reason. It will always have clearance for all size tubes. Your casting lines were very deep on that set. It does happen I am not going to oval out holes just to remove a slight casting imperfection. There is no horsepower loss because of that. How does the TB spacer look after the long trip?

Keith, I appreciate the quick follow up bud. I don't care how it looks, I was only worried about the function and since there's no HP loss, it's a non-event. Both spacers freaking look awesome man. Everything else looks great and I'll be taking pictures for this thread during the install.

It feels like a slurricane outside right now so I'm contemplating doing the work today.

Actually the re-install was going great until I broke one of the 5mm bolts that secures the injector housing to the runners . Called Acura and Honda dealers and it had to be ordered out LA so it's taking a week to arrive. Should be here tomorrow.

On another noob note, I dropped a bolt right next to the timing belt harness and heard it hit a few things and land on metal. I spent 2 hours fishing for that shit with a magnet and still can't find it. Would suck if it's stuck in a pulley.

Does anyone know if the 09 TL manifold has the same size "ports" as the 3G? Basically my question is, if I were to *hypothetically* get my stock runners ported and *hypothetically* purchase the 09 manifold, would they line up as if I had our stock manifold? (Accord V6 and 3G TL manifolds are identical).

^^^ so he gained only 21WHP and 11WTQ with the following mods:

PCD V3
2011 Acura TL-S SH 3.7 TB (max Bored)
2011 Acura TL-S SH 3.7 IM
P2R Acura Tl-S SH Thermal Gasket
Outlaw Engineering IM Spacer
07-08 TL-S Cams
WOW !!! thats ahem sucks !!!.....you should I remember the test car with Rodney went from 224 to 249 (25WHP) with PCD's and Jpipe.....

also we cant really point out what he is gaining from what mod.....if you ask me, he lost some power there.....PCD's + Type S Cams + Bored TB should gain you ~30WHP....

He also had a CEL with the intake leak. So I am guessing his losing a lot of timing. He has new dynos and the numbers still don't add up compared to Cubano accord.

He needs to fix the CEL and get the car tuned.

Cubano is awesome.

Thanks swoosh/ken for the links. And yes, Jiga has a leak in his injector O-ring, hence the CEL. Once this is fixed I think he will be in the upper 260s SAE untuned.

I refuse to believe the 3.7 manifold lost power. He is the only person said to have felt a decrease. Civicdrivr dynod 6whp/tq more throughout the powerband untuned on a ported 71mm TB, and a vacuum leak on his 3.2 CL-s before he went 3.6. He had I/H/P at the time I believe also. With a tune I think this manifold will make 10+whp over stock. Add the TL big bore throttle body and I'd guess an additional 3-4hp on top or the manifold. Plus the heat soak will dramatically decrease due to the Magnesium shell. Magnesium ftw. 09 TL manifold ftmfw.

why do you say the 09 TL ? isnt there a difference between the 09TL and the 11 TL SHAWD manifold and TB ??? (assuming you mentioned the SHAWD as well)....

i am thinking about it, but it will be an expensive deal....400 for manifold + cover....another 500 for TB then another couple hundred to just get em polished....

i might look into this after i get my cams/head work done....
