That's a fairly common problem for oiled filter elements with MAF cars. I would be hard pressed to put one into much of anything with EFI due to this issue. Carbureted, no biggie, gummed up electronics, no thanks.

Most of the problems have surfaced from folks who "clean" their elements and re-oil them with too much oil. But how do you know what's too much oil to cause the problem? It's not much of a science with a spray can applicator.

Just my $.02.

Will look into the turbo S oil cooler. Does anyone have comparison data for GT1/hybrid turbos vs. K-24?Thanks.

Unless you are going to take it to the track as a main function...hybrids are the way to go.

You "might" be right (depends on how you drive it on the street), but ... it was a recommended addition by the factory when upgrading even to their 450 hp kit, which is not the most aggressive of upgrades. Good insurance.

My understanding is that you won't see any "problems" without the extra oil cooler, but in hot weather, it is almost certainly pulling timing and thus pulling the extra power of upgraded turbos.

For street use the 993tt is much more than adequate. My favorite mods:
(1) SSK, completely changes the 'feel' of every shift. Unquantifiable improvement.
(2) PSS10s. lower the car if nothing else. Corners like heck to boot.
(3) RS front splitters and side skirts: much more aggressive look.
(4) 130 cell race CATS. incredibly deep rumble exhaust note after wards.

If you really want performance, then get Kevin's high flow hybrid turbos. They are superb. But once you touch the power 'switch', the endless slope begins.

Our aggressive look comes in the form of a WIDE ***. Besides, RS body parts don't work with the turbo bumper/widebody.

Could well be true. My Ruf is a NB.

The side skirts should fit though.

Though the NB and WB front bumpers are interchangeable, the N/A front bumper and the Turbo front bumpers are different, so the splitters are out. Also, the WB cars have different side rocker panels (where the side skirts mount).

Looks like you live in cooler climate. Ambient temps above 90 deg. will need aux cooler with 450 hp upgrades.

I drive my daily in 95F temps here in Houston without heat issues so far. K24's, no 2nd cooler - though I will be adding one soon for the sake of it

Ambient certainly effects performance, but the biggest heat issue w/a TT is the cats....too bad you're here in SoCal...be great to run the car w/o cats....those cats simply bake the engine....I've got Kevin's 100 cell 130mm cats and no mufflers...sounds good....but maybe not DD material.

Does removing the Catalytic converters not trip the CEL?

I would look into changing exhaust system. Fabspeed, has a good one, just replaced my old modified exhaust with the one from Fabspeed. Will post results in few days.
