987 v 986 Air box

Thank you for the clarification buddy...

For all you with children you know how difficult this is. I had a about a 2.5 hour window while little Lily was sleeping this morning. So out to the garage with some tools and the baby monitor.

Recap - My motor is a 996 3.4 so not the nice bolt up situation because of the cable throttle body. So I had to do some extra slicing and dicing. Here are the photos so far. This is as far as I got until the baby monitor called me in for sandwich time.

First slice

More cutting needed. The outer plastic around the main tube had to go, maybe didn't but It sure makes it a bunch easier to work with more space



After the extra was gone

To catch you up to speed I did some preliminary test fitting. I removed the drivers side intake manifold and the fuel rail was removed also on that side. I probably not need to remove the fuel rail but I did. You will notice in the pictures to come that all the open ports were taped over and filled to keep the crap out while working in there.



After I fit the box in there I test fitted my mass air housing. I am using a bmw housing, talked about elsewhere. So being that is not a direct fit I chopped off the oem connection point on the air box tube and fitted a silicone coupler that was previously used on my IPD piping (for sale now) and secured it with a T-bolt clamp.

I did clean up all the edges with the cutting wheel and a file so now they are all pretty. Sorry I didn't take a pic of that. I have not made a a patch piece for the muffler section yet. When I head out today I will pick up some apoxy and use a piece of the cut up box that is readily available right now on the floor of my garage.

In the car


Test fit of the maf. Still needs a clamp on the maf side.


This is where I am at for now. Maybe later on this evening after hours (baby sleeping) I will head back out and put the manifold and fuel rail back in.

Side note:

Anybody know if it is ok to reuse the injector o-rings? There in good shape, they were replaced when I put the motor in. If they are reusable, should I oil/lube them or anything?

Thanks for the info on that.

Nice work Jaay.....suprised you didn't just use the cayman MAF housing as you are a 3.4......unless your tune requires it

Actually they are really pricey so this may just cause and your reasoning

[JAAY]

BMW+Ebay = cheap :O) .. Not that I am trying to do my car cheaply but I have spent enough on this car. These are just the finishing touches right now. Thanks for the kind words.

Can you calculate the flow area of the grilled ellipse leaving the box going to the elbow section?
