I was planning on thoroughly cleaning my intake manifold to eliminate the carbon build up and serve essentially as a walnut blasting, just a little more elbow grease. Then I was going to purchase the Koala intake manifold spacer for $239.
But somethings have changed.
I heard from another individual on this forum that the spacer doesn't do anything, after realizing this he took it off. I figured that for all the supplies to really give my intake manifold a good cleaning would be about +/-$50.
Since the spacer does nothing (according to one person) and the cleaning can only do so much...Would it make sense to just buy a performance intake manifold?
It will cost more, yes, but I am also starting the build in preparation for a stage 2 tune.
Would it make sense to pay the money now and open up a few horses in the meantime?
Will I need to have one later on if I am doing a stage 2 tune?
What intake manifold would you guys recommend?
There are no replacement intake manifolds out yet. We have one in prototyping right now but it will be a fabricated sheet metal manifold with a very high price tag on it for fully built engines with over 300whp.
A carbon cleaning is never a bad idea on N14's engines and can add back a few lost ponies. I would recommend doing that even if putting stock manifold back on.
Keep in mind with a walnut shell blasting you're actualy cleaning the intake valves and not the intake manifold.
While yes you take the manifold off to do the service, and you can manually clean the manifold, the things you are blasting is acutally the intake valves on the cylinder head. I just wanted to make sure there is no confusion on what you're doing with a walnut shell blast service.
Like EuroTechzAZ said, no manifolds out yet and I wouldn't worry about the Koala spacer. Good in theory for N/A cars, but less results with a DI Turbo car.

Right right, I realize I missed that. I have been toying with the idea of just doing the cleaning of the valves myself. I'm not a mechanic and have little experience with these things. I want to do everything I can, myself, but it's a bit scary when getting into the motor and am certainly out of my comfort zone.

Here's a great walk through for you on the cleaning process.
This is exactly what I have been looking for. Thank you for sending me this, helps astronomically.
It sounds that walnut blasting is the only way to do this. I was thinking of just scrubbing with wire brushes and using chemicals but that would essentially require removal of the actual valves which is probably harder than it sounds.
@MarioKart does this fit with N18 Engine + AEM Intake?
You say port injection or methanol...Whats the difference?I mean..when you inject you inject methanol.
It looks DAMN GOOD.!!
