I know of the after market solutions.

Scca changed their stock rules allowing camber modifications that the manufacturer describe in either a tsb or fsm.

Any tsb or fsm camber allowances I would appreciate.

Has a Porsche tsb or factory shop manual ever suggested on the 996 using crash bolts, shims, or slotting to adjust the camber? Thanks!

Yes, it does -- item 13

1 - Mass air flow sensor

2 - Engine temperature sensor

3 - VarioCam valve

4 - Ignition coil

5 - Tank venting valve

6 - Secondary air pump

7 - Throttle potentiometer

8 - Idle speed air control valve

9 - Injection valve

10 - Knock sensors

11 - Hall-effect sensors

12 - Engine compartment temperature sensor

13 - Oil temperature sensor

14 - Resonance flap

I ask because I got CEL P0197 along with some misfire codes.. Any idea what the part number might be? Thanks!

Does the mk2 996 have an oil temperature sensor?

This is probably what you're looking for.

I've read alot about the ims and ems issues. Can a mechanic check the ims to see if it needs to be replaced? Would it be better to put the 1500-25oo into buying a 2002 911 turbo with 80-90000 miles?miles due to the engine being more"bomb proof"? The owner of the c2 is a friends relative so that is why the good price.

996NA low miles. Probly almost new car. I would anticipate no disaster other than IMS/RMS.

996TT high miles. No IMS problem, but maintenance costs more for a turbo, and much higher likelihood of parts breaking.

I would pick a low mile known history 996NA over a high mile 996TT.

996 mk1 stock size is 225/40/18 on 18x7.5, 265/35/18 on 18x10

996 mk2 stock size is 225/40/18 on 18x8, 285/30/18 on 18x10

996 mk2 widebody stock size is 235/40/18 on 18x8, 295/30/18 on 18x11

other sizes that will fit include

245/35/18 / 285/30/18

255/35/18 / 295/30/18

believe it or not, any of the above sizes will work on your aftermarket rims.

what size depends on what you're going after.

if you want better gas mileage, go thinner (e.g. 225/265)

if you want more comfort, go higher sidewall (e.g. 225/40 and 265/35)

if you want better traction, or appearance on the rim, go wider. (235/295)

if you goto the track or autox, try my alternate sizes.

good luck.

I have dedicated rims and winter tires for my C2 w/ PSM.

Driving in the snow is very doable, but requires more throttle modulation than summer driving to prevent oversteer.

PSM is also very helpful in the snow.

Get dedicated snow rims. Every time you mount/dismount tires, you risk injury to the tire sidewall.

Get the narrowest rims that fit your car. (e.g. if 8"/10" was stock, look for that width or thinner, e.g. 7.5"/9.5")

If you get used tires, get winter tires with lots of tread depth.

Wax the car well prior to winter.

Find a location to wash your car. I personally use Griots spray on car wash in my garage.

Have fun this winter!

what was your alignment before the X74?

you should be able to get more. -0.5 most stock cars can get.

it is possible that something could have been installed correctly.

also, sometimes the car needs to "settle" after suspension installation.

When I turn mine off, it stays off.

Like loren

assuming you have a C4 narrow body...

stock wheels are 18x8 et 50, 18x10 et 65

assuming stock suspension, stock tire sizes, stock alignment on a C4 narrow body

popular wider sizes that fit are 18x8.5 et 45, 18x11 et 60

slightly more aggressive fitments are possible depending on suspension, tires, alignment, etc.

good luck

See part CPT19 for dimensions. The old part number was 273-1P

Thank you. I got both CPT19 and CPT19x. They both appear to work.

Oops. Ignore my post above. Thanks

I got these on ebay. They look fine.

The seller and wheel repair company are named here.

http://www.6speedonline.com/forums/996-turbo-gt2/239523-kinesis-f110-wheels-cracked-must-see.html

18x11 et 60 +/- 5mm should fit, but depends on your alignment, tire size and type, suspension, etc.

who said 18x11 is a no go?

Loren,

I have a 1998 996 Carrera and want to know if I can run 11 x 18" rims like mk2 GT3 rims. Some say yes will fit no probes, others say no go.

Please let me know if you can help.

Regards

Justin

Hi - See TSB 7/04 on tyre sizes and wheels for a 996 Carerra under the DIY Menu. Gives you many options.

Loren,

Why couldn't I access the TSB's?

Thanks,

Scott

All fixed now...

That is terrible.

If I had sold you those wheels unknowingly, I would immediately accept a return and eat it myself.

Wow. I hope the seller does the right thing.

First of all, for anyone out there thinking about getting an oil sample this way, don't do it. If you want an oil sample, change your filter and you will have about 1/2 quart of used oil to play with that is in the filter housing.

That picture explains why I could not successfully use my oil extractor to change my oil.

Can you change the oil filter without first draining the oil from the pan?

I too plan to send my oil to Blackstone, but would be nice not to have to do a complete oil change.

Sounds like PS2s are hard to get in that size.

If you're going to replace your tires, consider:

Hankook Ventus V12

http://www.caranddriver.com/reviews/comparisons/09q2/tire_test_nine_affordable_summer_tires_take_on_the_michelin_ps2-comparison_tests/hankook_ventus_v12_evo_page_10

Sumitomo HTR Z III

http://www.tirerack.com/tires/tests/testDisplay.jsp?ttid=93

I've used both and they're a fine daily driver tire. Probably not the quietest, but performance in dry and wet is good.

If I had to pick between the two, I'd pick the Hankook. It was a little quieter and a little more durable. Good luck!

Does anyone know if modifying the exhaust this way increase or decrease power? I know that Porsche uses this same idea in their sport exhaust, but would they tell toy if it actually cause a power loss due to a decrease in back pressure?

the partial bypass is so small, the few that have dyno'd the PSE have not found any gain in hp or loss in torque.

I thought that this remedy for the "fast-reading" speedometer would have been investigated for a 2002 C2 by now, but I haven't found a thread that addresses this issue. So....I gather that from the lack of definite answers that no one here is sure whether the 235x40x18 and 295x35x18 tire sizes will cause a problem (such as rubbing the fender in a turn especially while the springs are compressed or cause an ABS problem of some sort); nor does anyone know for sure where the speedometer sensor gets its input. Maybe the reason that Porsche makes the speedo read fast with OE tires is so that for legal reasons it will not read slow with the largest diameter tires that can be accommodated??...just thinking out loud.

speedometer error is common in several cars, both american and foreign.

for the manufacturer better to err on the side of too fast than the opposite.

in some cars, you can trick the ECU to show the correct speed.

i don't think anyone has desired or found a way to do this on a 996.

your dealer is incorrect.

those tire sizes are for a 997 which has a larger overall diameter.

nevertheless, i'm running those exact 997 sizes without problem on my 996 40th, so they will fit.

i typically like to run larger sizes on my DD cars as it both corrects the speedometer error, reduces by 1% or so the actual miles driven, and cosmetically reduces the "wheel fender gap" making the car appear lower.

http://www.miata.net/garage/tirecalc.html

I recently did the "Gundo" or the "PSE" or the "Fister" hack.

Gundo may have been one of the first do it on a 997, but Fister has been doing it on 993s and 996s for quite some time.

In fact, you can buy it from Darin Fister at his website. fisterdmotorsports.

Since you have a mk1 w/ a 3.4L muffler, you will need a Fister stage II bypass. DO NOT get a stage I or PSE like bypass for a 3.4L since it won't work.

for a stage II bypass from inlet to outlet pipe:

-1.75" diameter, 16G stainless steel w/ bend, anywhere from 2 to 6" radius.

-if you buy the pipe online prebent, you can get a U-pipe and divide it in half for each side

-if you want louder, increase the diameter to 2" or more.

-ideally TIG welding, but MIG welding is ok if you're shop knows how to MIG weld stainless

-don't let the bypass pipe intrude into the inlet or outlet

-plasma cutter may help cutting the inlet / outlet pipe

note: the diamter of the stage II hack is not the same as the diameter of the stage I hack which was 2.25".

other note: the hack will note affect emissions.

Read this article from Panorama Magazine about suspension differences. The article is not specific to the 40th Anniversary cars but it does a good job explaining the US/ROW M030 differences.

996 Suspension Analyzed

http://web.archive.org/web/20030707142009/www.pca.org/panorama/sample_article_3.html

the link above didn't work, but I think this link is the article. if anyone could help me answer my questions regarding the US 40th AE springs, i'd appreciate it! thanks!

Whoever posted the 996 order guides, thank you.

Quick question.

I have an '04 996 Anniversary. Theoretically, could I have ordered options from other '04 996 order guides (e.g. PCCB, short shifter) that were not in my 996 Anniversary order guide? If so, would those options have been installed at the dealer or factory. I ask because the SCCA stock autox rules are pretty strict. Thanks.

Thanks both for your input. The logical conclusion therefore appears to be that US cars have US M030 suspension and Euro cars have ROW M030 suspension as standard although there is one other post that makes reference to M095 on the back of a Euro car but from what I can tell this would be the same ride height as a ROW M030 set-up (slightly stiffer perhaps?).

I will try the car and see what I think of it and base the purchase decision on that bearing in mind what I know about the suspension and costs associated with changing it.

Thanks again.

Still a little confused about the front springs. I have the US 40 AE.

Were there any differences in springs / shocks between the European and the U.S. AE?

I thought my car had a 10 mm drop all around (including the front)?

Does my US front have the US M030 (no ride height difference), the ROW std (10 mm lower), the ROW M030 (20 mm lower)?

Does my US rear have the M095 (10 mm lower) which is stiffer than the ROW M030 (10 mm lower)?

Thanks
