am getting ready to do another rms and wondered if I should use a different seal and tool from prior jobs? this is a 00 996 not gt3. thanks...should the IMS bearing be replaced always as a matter of caution on a 40K engine?

This car is odd in that temp rises to about 195F and tends to stay there. I've checked with PIWIS and fans can be operated through the tester-low and high, yet the fans do not kick in over 180 degrees. the ECU sends the signal to the fan relays so I'm a bit confused. Coolant level is ok and engine performs fine. Temp is accurate according to PIWIS. Cleaned radiators of debris also

WOWEY WOW...I thought I was the "chosen one" when it comes to these types of problems....I am following this to the end...one of the more challenging ones in a long time. PLEASE allow me to feel your pain! You did not mention if the car was tested by piwis when visiting the dealer and what it detailed. were behind u on this-good hunting-Mark the ***** is that no one on earth has had this problem!!

Has anyone used this height sensitive setup-I've used other but may change to different manufacturer such as KW which advertises this system?? thanks Mark

I applaud this thread for it's lack of discussion respecting HP GAINS! As a shop owner, I'm so disgusted with that BS! I can understand and support an alternative sound theme though. Many of the current "muffler merchants' (those built in US) are crafted of craptanium also. Today's Porsche has real quality incorporated into their exhaust parts. havefundriveporschetakechances-Mark

If you can get a code reader and post the codes, that will help a great amount. I had a similar problem and it was the coil pack. They are very picky and even if they are new, they need to be installed vey carefully. I would guess it can be as simple as removing the coil pack on 5 and then reinserting the coil. Cylinder 5 is acutally a tough one as far as the muffler bracket being in the way, so it is probably just the way that they put it back on. Easily can be an intermittent problem.

It could be just a bad connector to the coil that is causing you grief!

I would NOT DISCOUNT the intelligent comments of RFM-that guy is spot-on. :)? Marvel mystery oil--ha ha ha ha. Please, Im not taking a mickey on that but, with these machines! that cracked me up.....enjoy-Mark

Hi Guys:

Someone placed a call to us this moring (early) for an "urgent" Pre-Sale Inspection? I heard the "renntech" list named but the rest was garbled, no call ID. Sounded "time constrained". Please call again-FORMULA MOTORSPORTS-MARK-718-482-0515 THANKS

Anyone have the check engine lite come on for "engine Missfires"...If so, what codes and resolution has occurred. thanks Mark

I've degregulated the seat belt light by bypassing the plug....ANYONE know how to bypass the airbag light or jump the plug under the seats? thanks in advance

What wheels are these?

that's easy-they're RUF "Boat Anchors"! anyone ever weight them?

according to factory info, changed both the cam timing hydraulic unit and the com position sensor on bank 2 -4-6...all to no avail. download reveals same problem immediately after startup. anyone have this code problem?? Car runs fine. thanks BTW 03 996 tip

M9670-643 with X50 is a 340 KW (or about 462 HP).

Why are there so many different horsepower specs with cars that are all supposed to have the same engine?

With the later cars, we find it very important to have a pre-sale inspection performed. Many people (buyers, mechanics) overlook seamingly minor issues that may result in costly repairs...get it checked carefully...best few bucks you will ever spend on your new baby! There's a million stories that come with these cars. Mark My Two Cents.

What I do find interesting is the concept that it's all tied together and in order to get more power you need more air to mix with more fuel, bigger/better fuel pumps, larger turbos, bigger valves etc etc. All that simply means a lot more $$$$ so that you can get from stoplight to stoplight faster?

I guess this is reflected in the prices of the stage 1/2 vs 4/5 kits available today....

Even though I have a Porsche service business, ECU programming and my opinions tend to put a burr in peoples saddles. I mean no harm, just reality. The Turbo has always benefitted with a "small" increase in manifold pressure due to the way the factory is conservative with OEM pressures. The factory runs their tests VERY hard prior to introducing a new model. A "typical" increase of 2-3 lbs makes a very nice improvement. Many of our clients run hard at the track, where ambient temps can soar....this few pounds has not caused typical detonation problems, especially with higher octane fuel.

The normally aspirated engines have a very good program(s) built in. I've seen minor improvements on engine dyno's, yet on the track or street the improvements are very marginal. ANY time you increase boost, there will be a noticeable improvement. This has been the typical case for decades on the Turbo. More aggressive manifold pressures MAY be tolerated in short bursts with a cold intercooler on the street, NOT on the track under strenuous driving conditions. We have changed many P/C sets and heads on 996 Turbo's due to that particular set of circumstances. My biggest "peeve" with the 996 Turbo is the lack of limited slip and the continuous brake application necessary with PSM under rigorous driving. With all the money people spend on upgrades, why they don't get a GT2 is amazing. NOT to mention, trying to sell it after all those mods. Mark

How can a retailer know more about a product than the own manufacturer?

Your best bet is really to contact Remus directly.

Hey ChucK-can we see a picture of those wheels-price sounds great

We tried that with GT2 wheels...not even close

I'm concerning if 345/30R18 MPSC tires on 12" alloys fit GT2 wheel arch?

Maybe somebody has experience with wider tires. I would like to improve traction and one size up from standard 315 is 345 which is within Michelin recommendation for rim.

Thanks

I'm running in a DE this weekend. There is fuel available at the track up to 110 octane. I usually run premium in my 05 987S 93 octane.

Will a higher octane help my performance? I read earlier posts that say the engine will automatically adjust to the fuel. Is there a maximum level the car can use effectively?

The use of "higher" octane fuel in performance environments have been persistantly discussed by my clients as well as peers....with the ultimate, undeniable/PRACTICAL conclusion THAT.......use the "pump" premium, it's more than capable of propelling you to track euphoria!

does anyone know if Fabspeed headers will add power and torque if i keep the stock exhaust system? ultimately, i want the increased pep with aftermarket exhaust systems, but i don't want to loose the factory sound.

any info is appreciated....

This type of subject, unfortunately, come up on topic all too often. The simple reality of the Porsche line is that they are already an engineered, HIGH PERFORMANCE machine....out of the box. Almost to the total aftermarket suppliers, they offer products that do NOT INCREASE true performance from these ENGINEERED machines. Deception in the advertising and inferior manufacturing processes often lead to a car that has become a pariah....NO ONE wants to buy it anymore. Funny, when we logically think of the REAL, bonified engineers who put science and technology into each and every part of a Porsche 911?....well, how can we believe that some of the aftermarked "wizards" can beat the factory at the factory's game! PLEASE.....They border insults in the ads in eurotrash mags!. Headers? What do you think you have to begin with? Stack the two headers together, look, think! Which header will stand up longer, which header is "fitted" to the engine management better? The aftermarket should be smacked! the buyer of this crap should be smacked for being so stupid! Do you homework and you will conclude what thousands of others do, without throwing your hard earned cash in the garbage. Sorry, I do this once in a long while, the educating thing...REALLY pisses of the guys that make this junk:-) AND. let's NOT talk about AIR FILTERS!#$%^$^$% havefuntakechancesdriveporsche

This problem is why I reached out. It seems unusual. Client bought car in Fla then drove it up North. obviously on highway it's ok. But, with fan speeds not working car overheated as they slowed down in traffic. Tester cannot get speed one or two to work. engine fan works. fuses are ok. WAS hoping someone heard of this problem. ****, one day I'll get a break on one of these diagnostic problems, without doing the work myself:-) thanks for helping anyway-Mark

we cannot get the fan 1st or 2nd speed to work, even with systems tester. Anyone with a similar symptom? thanks Mark

I would first check the relays and pin out the connectors to the fans, making sure you have good ground and batt supply. If the relays are both not working

then you need a wire diagram to analyze the circuit and determine if ineed the dme is the problem. Dme is very expensive so you must be sure of your

diagnosis.

To bad you arent close to san pedro ca. Id help you out, I used to work at the dealer.

will the 996 GT3 Seats fit a 997 GT3?

so there is no way in the world you can have the roll cage and a sunroof either.. does the sunroof not slide within the roof?????

Cannot order a US car with Sunroof Delete!!! Means no factory roll bar either....dumb cement heads screw it up again, just like the RS which really is a BS deal, Oh I forgot....you get the single mass flywheel and pretty wheels!

I am just about to take delivery of my 3rd GT3 which is a 997 RS ,

The cars are used for Tarmac Rallying in Australia.

Problem : currently in Aus there are no "R" spec tyres suitable for use in competition that will fit the rear of the GT3 or RS (305/30ZR 19).

The standard tyres are not suitable for competition as they are hybrid compounds and to "hard" for fast competition use.

Does anybody have details of a competition tyre that will suit and where I can buy them from. They must be "DOT" approved for road use.

Any assistance would be greatly appreciated.

We're looking for the good fit for BBS in 18" with R tires too? any info would help/ looking a slicks now

Hi guys

there seems to be a question on what is the proper size and offset in 18" and what size slicks to run with that wheel configuration for track events-ANY one have similar setup? We'd appreciate input very much. thanks Mark

Ian talks the talk: I walk the walk-we both agree that HP improvements is expecting the wind to pick up the sails...all smoke and mirrors. Save the dough, blow the ride for a better one! Don't be a schmuck like a lot of guys do on that "other" site. How the hell does some bumf==k in bumf==k idonknowwhereville sit back a say he can beat the factory at their own game. Same thing said for all that additive crap we see on the idiotbox that does wonders(****) for the longevitiy and performance. If this garbage was so spectacular the OEM's would be using it, or buying the guy out!. SOOO SICK of the bull**** artists out there. Todays Porsche engine cannot see any appreciating performance gains from bolt on ****, period. Unfortunately, it's what I do too!-M

BTW- a product called Ventil Sauber does help clean the intake/fuel stream, as well as the valves. I say this to validate that I do suggest some things-

If you want more power from a stock 996 C2, you should consider Exhaust and intake, other than that sell your car and get a turbo or GT2- GT3.

Forget aftermarket trash for the 996 Carrera. You'll only waste fortunes getting very little power for a lot of outlay and make the car impossible to sell - Porsche buyers seem to be particularly anal about original spec. etc. In reality there is nowhere to go with this engine apart from supercharging which is very expensive. Intake kits simply don't work. Mufflers give 2-3 BHP at best - the rest is lies. Headers, 200-Cell cats and mufflers with a re-map will give you 15 BHP absolute max. Porsche's own power kit requires gas-flowed heads, headers and intake plenums plus much more aggressive cams and mapping just for 25 more BHP. Even then the performance of the cars when measured is almost no different - go figure! Every reputable tuner will tell you there is no real extra power to be had from the M96 engine.

One thing it does like however is very high octane gas. Put 99-100 RON in the tank and reset your DME. You'll be surprised.

By far the better route would be to sell the car and put the hard-earned towards a Turbo. Even stock, a Turbo has way more performance than you could ever realisitcally and reliably achieve from tweaking a Carrera. And of course, the Turbo CAN be tweaked enormously for modest outlay by virtue of being able to increase the boost pressure.
