Engine

Good morning!

If one were to upgrade their base level C2 with performance bolt-on upgrades with a combination of headers/intake/exhaust, would a tune be required to bring the cars potential up to par?  I understand the cars ratios might also be affected.  Assuming no CELs are tripped and the car responds fine to the upgrades... I am asking purely on the standpoint of bringing out the cars potential from that point forward.  

I also understand building a vehicle like this would only be legal for track use and there are street legality issues, etc. etc.  

I've done some research on this topic but can't really get a good answer as to the benefit of Porsche Classic Oil for the 996.  I'm not a fan of zero weight oil's but I currently use the 0W-40 Mobile 1.  The car has been to one 2 day HPDE event and is mostly used for spirited driving during the warmer months in New Jersey about 2,500 miles per year with 31,xxx miles on the odometer.  I change the oil in the spring  annually due to the low miles driven and can pick up the 0w-40 really cheap at Costco. 
 

Hi , Trustworthy mechanic in the Midwest Chicago area?  I am 99% sure I have a cracked cylinder head or 2.  Oil in coolant. Engine runs fine,no overheating. I have replaced the AOS,Oil Cooler an associated hoses. I understand this will be expensive just do't want to get ripped off.

Thanks in advance

How do I locate the sensor?

Oil pressure drops to one bar with engine at operating temp at idle.

Oil level is fine.

Hi. I've recently noticed the smell oil hot/burning oil when I return from a drive. There are never any drops of oil on the floor. Do you think the spark plug tubes might be the culprit? Other ideas? Thank you. Tony

Hi Guys,

Can you tell me what is involved in swapping my 1999- 996-3.4ltr for a 2002 -996-3.6?  

Thanks a bunch,

I am trying to determine exactly what motor I have in my 2000 Carrera. I imagine the VIN would indicate that but I do not know which digit(s) deal with the motor type. VIN is WPOAA2992YS621965. Thank you.

Looking for a great repair mechanic for a cracked #6 cylindar.

I recently ran my first 2 day HPDE event on fresh 0w-40 Mobile 1.  The oil was changed a month before the event and had less than 100 miles on it at the start of day one.  I know its always good cheap insurance to change the oil often but is it recommended after running the car on the track?  IMS was done before I bought the car and the filer was free of any debree upon the change leading up to the event.  I work with a guy that changes before and after every autocross event but that is on a STI.
