Track use can bump that to over 300F\. The LN Engineering Billet \(not cast\) 2 QT Deep Sump Oil Pan Kit inc\. pickup tube extension for 2016 and later four cylinder 982/718 Boxster and Cayman models with the MA2\.20 or MA2\.22 can reduce operating temperature \(may require modification to underbody cladding to direct airflow to the pan's integral cooling fins\) while extending oil life\. More capacity means it takes longer for oil to get overheated and longer for oil to breakdown and shear out of grade, both are situations which can lead to increased wear or engine failure\. \Tatum Racing\ was the first to run the BRS 2 QT deep sump on one of their 718 race cars\. Where they would regularly see the car get hot enough to go into limp mode on track, the additional 2 quarts of capacity dropped oil temps enough to solve this troubling problem for good\. It is a must for every street and track car\. \Note: Includes oil pickup extension; designed to work with the factory oil baffle \(not included\)\. \ 718 GTS/GT4/Boxster Spyder models with the 4\.0 liter engine \(with plastic sump pan 9A2 107 309 00\) use part number 106\-00\.12 designed for the 9A2\. - [Bilt Racing Service BRS Billet 2\.5 QT 9A2 Deep Sump Oil Pan Kit for 991\.2 992 718 \(6\-cyl\) Models](https://lnengineering.com/bilt-racing-service-brs-billet-2-5-qt-9a2-deep-sump-oil-pan-kit-for-17-19-991-2-models/): The ideal engine oil temperature for a modern water cooled engine is 220\-225F\. Track use can bump that to over 300F\. Besides higher oil temperatures, the factory oil pan on 991\.2 Porsche engines is plastic\. Yes, plastic\. We've already seen many vehicles with damage to the plastic pans and even one engine that failed after the pan was damaged\. The LN Engineering Billet \(not cast or plastic\) 2\.5 QT Deep Sump Oil Pan Kit inc\. pickup tube extension for 2017\-2019 991\.2 and 2020 and later 992 models with the MA2 engine can reduce operating temperature \(may require modification to underbody cladding to direct airflow to the pan's integral cooling fins\) while extending oil life, not to mention being stronger than the factory plastic oil pan\. More capacity means it takes longer for oil to get overheated and longer for oil to breakdown and shear out of grade, both are situations which can lead to increased wear or engine failure\. A must for every street and track car with the MA2 engine\. Custom stainless baffle as shown is included in this kit\. Also fits 718 Boxster and Cayman models with the normally aspirated 4\.0 liter 6\-cylinder engine\. Replaces factory part number 9A2 107 309 00\. Please verify this is the correct part for your Porsche before ordering\.

Also fits 2010\-2013 Porsche 911 T and GT2RS 2nd Gen as well as 2010\-2016 Porsche 911 Turbo / Turbo S models\. A must for every street and track car with the 9A1 engine\. Baffle in photo not included \(utilizes the factory oil control baffle\)\. You can reuse the factory profile o\-ring or replace with new factory part 9a1\-107\-325\-02\. Instructions for installation of the oil pickup extension can be downloaded \here\\. Does not fit 991\.2 or 718 4\-cylinder models\. For 991\.2, use part number \106\-00\.12\ for 718 4\-cylinder models, use part number \106\-00\.13\\. Our billet 2\.5 quart deep sump also adds a second drain plug to allow for faster and more complete draining of used engine oil at time of change\. Both LN Engineering magnetic drain plugs are include in the kit\. Kit also includes a pickup tube extension to ensure added oil can be utilized\. Factory oil control baffle and oil level sender bolt on without modification\. No other deep sump on the market allows correct measuring of oil level through the dash interface\. - [102\.00mm 996/997TT, GT3 Machine\-In Nickies Mezger Sleeves \(Aluminum\)](https://lnengineering.com/102mm-996-997tt-gt3-stock-replacement-nickies-aluminum-machine-in-uses-105-4-sleeve-registers/): LN Engineering's billet aluminum Nickies sleeves optimized design provide superior strength and cooling over the factory cast aluminum Nikasil plated sleeve\. Typical specifications for our proprietary alloy provides 50\-60% improvement with a similar increase in thermal conductivity over the stock 100mm cast aluminum sleeve\. When Porsche increased the bore size larger than 100mm, they switched to Nikasil plated steel sleeves which have significantly lower thermal conductivity\. Our machine\-in Mezger cylinder liners use the registers of the steel 105\.4mm sleeves, but are made out of billet aluminum for increased strength and cooling over factory steel cylinder liners\. The water jacket and case both need to be machined to accept the 108\-102 Nickies Mezger sleeves\. Requires the use of factory 102\.7mm head gaskets or custom Cometic head gaskets \(both sold separately\)\. ## Lists - [FSI \- All Engine Customers](https://lnengineering.com/ctct_lists/fsi-all-engine-customers/) - [Current Air\-cooled in works customers](https://lnengineering.com/ctct_lists/current-air-cooled-in-works-customers/) - [FSI \- Class of 2023](https://lnengineering.com/ctct_lists/fsi-class-of-2023/) - [IMSS Certified Installers](https://lnengineering.com/ctct_lists/imss-certified-installers/) - [LNE \- Wholesale Store Newsletter](https://lnengineering.com/ctct_lists/lne-wholesale-store-newsletter/) ## Documents - [Coatings, WPC, and Surface Treatments Inside a Porsche Engine](https://lnengineering.com/document/coatings-wpc-and-surface-treatments-inside-a-porsche-engine/) - [Fall is coming\.
