with all due respect, why are you redoing the job? did the last guy screw it up?

you can do an oil catch can if you so choose. and throttle body bypass.

im spacers dont do anything. just get an oem gasket to replace the old one if you want

u could always put in injectors

if you make sure to warm up your car in the winter, there should be no problems with it. but its your choice

and the tbb also makes removing the upper im easier

wut for? save your money for real performance.

BSR for one.

you could install the Outlaw enginering intake manifold spacers,  I've got one of these waiting to go on with my ported and polished IM and ported TB

I thought it was just proven that spacers dont do anything at all...

They are heat resistant spacers, made of plastic not metal.  The theory behind it being less heat soak from the motor to the IM's and TB.

Not to be confused with a notorious 'Angled Intake Manifold Spacer'.

FYI.

if you are worried about the thickness of the Outlaw Engineering spacers you could just get the Hondata IM gasket that reduces heat soak just between the head and the IM

Im cleaning the TB and the IM, should i get TB cleaner, carb cleaner, or both?

So I guess TB cleaner will be better for the TB obviously, but can i use that on my IM too? red02v recommended i use carb cleaner to clean my IM since i will have it out.

Sweet, thanks. Hey Marc, did you ever install those Outlaw spacers like you said you might?

when I installed my ported and polished IM I  also wrapped the fuel rail and injectors with Thermo-Tec wrap to reduce temperatures of the fuel and the coolant hard pipe that runs under the exhaust manifold.

Does anyone know if there is a how to or any help for removing the lower IM? The upper is easy because of the Butterfly how to.

Here, a sample of my write up.


6. Remove your fuel rail. This is sorta kinda halfway tricky. I believe it's 2 12mm bolts. The tricky part is not losing the two bushings behind the fuel rail where the bolts go through. Do NOT lose these. Remove the rail from the lower intake manifold but GENTLY tugging at it to break the o-rings free. I normally start at one side and work my way down. You DO NOT need to remove the injectors from the fuel rail. Once it is remove, verify that the o-rings are on the injectors. If they are not, then dig them out of the manifold and put them back on the injectors. You may want to wipe them down. *optional* Use a fuel line quck disconnect and remove the fuel rail from the fuel line. I didn't need to do this. I simply set my entire assembly off to the side around the transaxle.

*optional* Remove the lower intake manifold. This is not really that hard to do and I did it. There is a couple of tricky parts but nothing too bad. First, you have to remove the 2 12mm nuts on either end. Then if I remember correctly, you have 1 12 mm bolt on the top in the middle, and 2 12 mm bolts on the bottom. The 1 on the top is easy. The two on the bottom required a 8" extension and a 12mm deepwell to get to. It's easy enough. Break them free and you should be able to get your hand inbetween the runners to turn them out. Then you need one of those e-torx to remove the one stud on the passenger side. Don't lose this guy. I removed both of them for the hell of it.

7. Remove the 4 bolts holding various equipment to the lower intake manifold. These are fucking PMSing BITCHES! First, remove the 10 directly on the back side. Not so bad. Then, get the two that are underneath and to the passenger side. These suck. Remember, there is FOUR total.
I'm pointing to the two brackets here in this picture.

What was your opinion of the PnP IM after you got it on the car?  I have been considering this for a while.

I was really impressed it felt like the car was just faster to respond and really pulled I also installed a ported TB, TB spacer, TB bypass and the Hondata IM gasket at the same time so I would say it was an overall great combo.  I am planning on redoing everything under the hood so when I remove the IM I am going to finally install the outlaw engineering Kit that has been sitting here for over 2 years.  I say if you have an extra IM to send to be ported it is well worth it I had mine done about 2 1/2 years ago by Wperdigon But there is a company listed in the group buy section I think that is doing it now.
