TSX Intake Manifold DIY / Q & A

[timot_one]

You can bore your TB, or you can pick up a K20A2 TB and get an adapter.  I think Karcepts may make one.  Another option would be the Hybrid Racing 70mm TB, but you're going to need to machine the inlet of the TB and port match them, otherwise you're wasting your time and money.

Tim, I'm just curious, but do you think an 04-05 TSX intake manifold would work on an 06-07 Accord? I know the 04-05 TSX IM has the IACV notch, but the 06-07 Accord TB doesn't have one, so it would be blocking it off anyways. The only thing I can think of is the bore of the 04-05 TSX IM being too small to match the 06-07 Accord TB. the 04-05 TSX IM is what, 60mm, while the 06-07 TSX IM is 64mm?

I was just wondering because I've still got my 05 TSX IM from my old car haha.

If the bore of the IM is smaller than the bore of the TB, then you would need to get it machined.  If you don't, you will lose power because of the turbulence created.  Only other thing I could think of is the TB bolt pattern being different.  I don't have one, so I don't know if they are the same or different.

Good write up Tim! I seen this post on DriveAccord.net Keep up the good work Tim!

I can't take credit for the DIY.  It was Skippy that originally posted this, I just copied it over here.

Ok, my bad. Thanks Skippy! =D

Since he doesn't really come on the site that much any more, I'll let him know you appreciate it the next time I talk to him.

Sorry to bring this back to life...finally getting around to tackling mine sometime in the next few days.

Quick question - is there a gasket in between the intake manifold ("plenum") and the engine. I see it says to only pick up a throttle body gasket.

[Jeff Likes Bagels]

There is a metal gasket between the intake manifold and the injector base that's reusable.

Thanks to whoever put this in the right spot and thank you Jeff for the quick response.

Quick question - I was going to install the intake manifold but a buddy of mine suggested I look into the RBC manifold the TSX guys swap theirs out for. Would it fit?

[timot_one]

It will fit, but you will lose power. That manifold is for higher revving motors. Your motor doesn't rev high enough to actually see those gains. You will lose power in the lower rpm range.

That explains it.

Gracias, Tim.

De nada Eric.

So I bout a TSX intake manifold recently. After getting it I could see that it was stored somewhere for a while and there is spiderwebs and other residue inside of it. How do I clean it properly?
