Right Click Save As :) haha that guy is a man after my own heart - yes I remember his car all too well and would love to one day see it.

There might be a little something to isolating the IC from the engine bay...hehehehe *cue mad scientist laugh*

Is there any possibility / room to bolt the air filter straight onto the turbo's in that location?

The K16 compressor cover has a 2 1/4" inlet... wondering if I could just bolt two K&N filters straight onto the turbo's, instead of stuffing around fabricating intake pipes up into the engine bay?

I guess it'd get dirty pretty quick down there eh?

Have been sidetracked with work, family and life in general...am so close to finishing, need to take a week off of work...however, happy having a job right now with things as they are in the economy

I have been meaning to start a thread with my project...

As for the question of air filter placement, there is plenty of room to mount them directly to the turbos (see the pictures). However, I was concerned about all the heat in this area.

Just beautiful! You're right on the amount of heat down there for leaving the filters with a rain sock on the turbo, not a good thing down there. Even the 935's had piping to get to a distance from the engine bay to an area of controlled air intake.

Good luck with getting her buttoned up - she's absolutely wonderful to look at.

With the height of the turbos bolted onto on the 993TT headers, is it high enough to actually run 10AN drain lines line down into the oil sump drain port under the motor, via a 10AN "T"? How much downward slope is there?

Just trying to get away from having to buy an oil scavenge pump, that's all. That's how I drain oil from my existing single GT35R setup.

I dunno if this helps any but on my 964 based motor (custom equal length headers though) the turbos have a drain setup and not a scavange pump as they're above the height of the oil return I believe. So its possible.

Thanks. On the 3.2 Carrera motor, the oil sump drain plug is THE lowest point on the motor. It's unlikely the oil port on the K16 is lower than this point when mounted on the OEM 993TT headers. It may just require some round-about routing of the oil drain line such that it's a downward slope all the way, but I guess I'll have to determine the feasibility of this solution once the turbo's are mounted in place :confused:

Gravity drain is such a simple, effective and reliable solution :cool:

Gravity drain won't work with the 993TT headers in stock form- the 993TT has large drip-tanks under the turbos that are pumped dry by a scavange pump acting off the intermediate shaft. The drain plug is the lowest point on the motor, but the oil level in the motor is higher than the turbos' center housings are mounted. The stock twin has upward battles with this very concept- there were a batch of bad oem filters going around a few years back that allowed the oil in the motor to drain into the turbos and past the seals on shut down. This is the reason that porsche installed check valves on the 996TT. Notice that My3.6Turbo has a Tilton pump pumping the sumps dry.

I hadn't noticed. Is it a single Tilton pump, or dual pumps?

Is it this one? Wonder if it has enough scavenge capacity for two turbo's, or if I need one for each turbo? TurboWerx pumps can be used for twins ;)

Ooops! Ah yes, I see it where the distributor is usually located. Looks like he might be using two pumps? I heard these are not suitable for hot turbo oil scavenging and will not last?

I do not know how long it will last with the heat- never tried one before. I think one would be enough to pump both turbos, those things really suck...

Pump was purchased from TurboWerx has a flow rate of 1.75 GPM and will support two turbos with sustained temps up to 300F...should be fine.

As for gravity drain, if I removed the catch tanks and attached a line, it would run nearly horizontal to the sump plate...not sure it would drain properly. My headers are 996tt, not 993tt, but placement is nearly identical. Definitely can't drain into the valve covers. Also wasn't confident that the factory cam driven pump could adequately support two turbos.

Here is the pump description from the TurboWerx website...They also have another version (Exa-Pump) with higher specs that was not available when I bought mine.

Electric Oil Scavenge Pump

No more limits on turbo location!

Proven, powerful, and quiet. Manufactured exclusively for TurboWerx, this custom engineered pump is designed to scavenge hot turbocharger drain oil from anywhere to anywhere in automotive applications. With its 1.75GPM (105GPH) scavenging capacity, it is powerful enough to scavenge oil from two turbos. It will self-prime/draw from over 5 vertical feet, and pump the oil as high as 20 vertical feet. The custom black anodized finned heatsink lowers operating temperature, further enhancing reliability.

Whether the application moves 1 oz of oil a minute or up to 1.75 gallons a minute, 'under-flow' applications are no problem. In fact, the TurboWerx pump may be run dry indefinitely.

This pump will fit inside a 7.25" x 4.0" x 4.0" box. It weighs less than 5 pounds, and includes anti-vibration mounting hardware. It is specified to handle a maximum oil temperature of 300+F, and the power consumption is 12 volts @ less than 3.5 amps. Pump inlet and outlet fittings are standard 3/8" NPT. Also suitable for other fluids, such as transmission, engine coolant, and water.

Ah yes, TurboWerx. That is the route I'll take with my setup and just pump the oil back into the left lower valve cover. I'm running 10AN oil lines throughout... probably overkill! :confused:

I ran mine into the chain cover...didn't even need to tap or weld on a bung. Also was able to fill the empty space where a distributor once was and provide plenty of airflow for extra cooling

Absolutely perfect location with good airflow for the pump... Unfortunately, I won't have the luxury of having that space as I'm slipping in a 964/993 twin distributor for my twin plugs.

Need a nice central location for the pump... hmmm?

You going to be running custom heat exchangers???? There would be plenty of room forward of the engine by the transaxle if you were not.

I'm using that same pump on my transaxle cooler setup. It'll pull plenty of fluid even if it's not balanced between both turbochargers(centered)

Nope, I'll be using factory 993tt heat exchangers. Good point! Ahead of the motor would be good. Or even under the parcel shelf, where I have my Crane ignition system located :)

I'm running a 993TT race car in heat of Florida with a stock intercooler. A Seacan is way outside my racing budget. Is a Protomotive better than stock and how much better? The $3500 is much more workable. Are there any other good I/c out there that are readily available?

Something could be fabricated to work with the stock throttle body, yes.

Usually, we convert to the '95 non-turbo throttle body, similar to the GT2 Evo engines.

Here's one we recently finished for a ~600hp 993TT street/race car running in BR, conditions hotter and more humid than FL. The IC supports 800whp.
