WHEN REBUILDING AN M96 OR M97 ENGINE, THERE ARE MANY CONSIDERATIONS WHEN EVALUATING YOUR OPTIONS.

Re-ringing your M96 or M97 engine isn't even an option for most rebuilds, however most engine builders re-ring engines after only doing a visual inspection of cylinder bores rather than measuring the cylinders for ovality and taper. It is a guarantee if the engine has not been sleeved, the bores are out of spec on even a "fresh" rebuild.

Through our exclusive Nickies sleeving process, we have overcome the d-chunk, slipped-sleeve, scoring, as well as taper and ovality issues associated with Porsche 986/996 and later 987/997 models.

The price shown is for all six cylinders on the block process. Includes custom Mahle Motorsport pistons, rings, pins and clips sold exclusively by LN Engineering. Service applies to M96.03 and M96.05 engines.

Additional Notes

We do not flat rate pricing on cylinder head rebuilding for VW Type 4 / Porsche 914 / 912E or Porsche 356/912 engines; we do however offer new replacement Porsche cylinder heads. For engines that have or will see track or race use, we recommend replacing all valve seats, valves, springs, and retainers. For M96/M97 or 9A1/MA1 cylinder heads, cam covers can be sent with the heads if you would like them to be cleaned. Additional fee applies. Please be sure to remove your camshafts and other accessories such as lifters, lifter valley/cradle, Variocam components, etc. from the cylinder heads prior to shipping. If additional disassembly/handling is required, you will be billed at shop rate. If we are twin plugging your aircooled Porsche 911 cylinder heads, we can modify your lower valve covers for twin plug. Additional fee applies. Each head should have been individually boxed with rigid padding on all sides then each individual box put into a larger box with more padding on all sides. Use of plastic cases, bubble wrap, air pillows, peanuts, or shredded paper is not acceptable. Package your cylinder heads assuming they are going to be dropped or possibly launched out of a cannon. This service does not qualify for free shipping.

Bilt Racing Service's newly revised electric power steering kit includes a 100% new electric power steering pump (not re-manufactured), custom CNC machined rack fittings, lines, reservoir, wiring, P/S pump delete pulley, and an OEM belt.

Reduces parasitic horsepower load from engine and moves weight to the front of vehicle. Eliminates power steering lines going from front to rear of vehicle as well as the problematic plastic power steering reservoir and factory mechanical pump for added safety.

NOTE: Due to mid-2019 update of the kit some components shown in pictures and in the installation manual are no longer necessary and included, like the fluid reservoir that is now integrated with the pump body. Functionality and installation steps remain unchanged. Not designed for GT3, Turbo, GT2 models.

Bilt Racing Service Power Steering Cooler Kit.
No cutting or splicing required. All lines come pre-assembled with custom fittings and hardware making this kit truly plug and play.
Fits all Boxster, Cayman, and 911 models from 1997 through 2012 including Turbo, GT3, and GT2.

Custom billet aluminum rack stops used to limit the amount of steering lock the car has to prevent rubbing when using wider than stock front tires to help minimize sidewall rubbing. Sold as a pair.

When positioning your foot back onto the throttle sometimes a small stumble on the pedal can lose time. Sometimes this can occur when cars have removed interiors which can leave large openings to the left of the pedal. Our foot stop ensures your foot will land in the same palce everytime.

2009-2012 Cayman pedals have two recesses on the backside that correspond to the holes in the stop. However, this can easily be adapted to any pedal.

The Bilt Racing Service carbon mount holds a Motec C125 datalogger and attaches to the plastic column cover right behind the steering wheel. Mount can also be modified to fit numerous other vehicles as long as a flat surface is provided for attachment.

Installation Method for Porsche Head Stud Kit

Part Number: 204-4210
Application: Porsche 3.6L Turbo Water-Cooled Engine

1. Always verify the part number for your application with the part number on the side of the box and the part number on the instruction sheet.
2. Clean and inspect all hardware prior to installation. Look for obvious defects or shipping damages plus proper fit, length, and dimension.
3. To ensure proper thread engagement and accurate torque readings, clean ALL threads in the block. Chase if necessary with ARP Thread Chaser part number 912-0003 (M10 X 1.5).
4. Screw the head studs into the left-hand and right-hand engine cases "HAND TIGHT ONLY". NOTE: LOCTITE MAY BE USED IF A PERMANENT MOUNTING OF THE STUDS IS PREFERRED.
5. Install the cylinders and the cylinder heads as described in the Porsche factory service manual. Check for binding or misalignment.
6. Lubricate the stud threads, nuts, and washers with ARP ULTRA-TORQUE FASTENER ASSEMBLY LUBRICANT. Then install the washers and the nuts onto the studs and tighten them hand tight. ARP recommends using the ARP ULTRA-TORQUE FASTENER ASSEMBLY LUBRICANT that is provided with each kit as opposed to motor oil. This is due to higher friction on the studs as well as inconsistencies in the clamping force of the fasteners when motor oil or other low-quality lubricants are used.
7. Following the manufacturer's recommended torque sequence, tighten the nuts in two equal steps to 38 ft-lbs with ARP ULTRA-TORQUE FASTENER ASSEMBLY LUBRICANT. Note: ARP Ultra-Torque Fastener Assembly Lubricant has been specifically designed to reduce tension preload scatter and eliminate the need to cycle high-performance engine fasteners before final installation. ARP Ultra-Torque far surpasses all requirements offered by previous ARP lubricants in terms of fastener preload repeatability and performance lubricating properties.

Part Number: 204-4707
Application: Porsche 3.4L Non-Turbo Water-Cooled Engine

1. Always verify the part number for your application with the part number on the side of the box and the part number on the instruction sheet.
2. Clean and inspect all hardware prior to installation. Look for obvious defects or shipping damages plus proper fit, length, and dimension.
3. To ensure proper thread engagement and accurate torque readings, clean ALL threads in the block. Chase if necessary with ARP Thread Chaser part number 912-0003 (M10 X 1.5).
4. Screw the head studs into the left-hand and right-hand engine cases "HAND TIGHT ONLY". NOTE: LOCTITE MAY BE USED IF A PERMANENT MOUNTING OF THE STUDS IS PREFERRED.
5. Install the cylinder heads as described in the Porsche factory service manual. Check for binding or misalignment.

ARP recommends using the ARP ULTRA-TORQUE FASTENER ASSEMBLY LUBRICANT that is provided with each kit as opposed to motor oil. This is due to higher friction on the studs as well as inconsistencies in the clamping force of the fasteners when motor oil or other low-quality lubricants are used.
7. Following the manufacturer's recommended torque sequence, tighten the nuts in two equal steps to 60 ft-lbs with ARP ULTRA-TORQUE FASTENER ASSEMBLY LUBRICANT. Note: ARP Ultra-Torque Fastener Assembly Lubricant has been specifically designed to reduce tension preload scatter and eliminate the need to cycle high-performance engine fasteners before final installation. ARP Ultra-Torque far surpasses all requirements offered by previous ARP lubricants in terms of fastener preload repeatability and performance lubricating properties.

Installation Method for Porsche Main Bolt Kit

Part Number: 204-5001
Application: Porsche 3.4L-3.6L (Non Turbo) Water-Cooled Engines

1. To ensure proper thread engagement and accurate torque readings, clean ALL threads in the block. Chase the threads if necessary.
2. Clean and inspect all hardware prior to installation. Look for obvious defects or shipping damages plus proper fit, length, and dimension.
3. Make sure there is an adequate chamfer around the bolt holes on the main bearing cap housing to clear the radius on the under head of the bolt.
4. Install the bearings and the crankshaft into the main bearing housing and assemble the housing halves according to the Porsche factory service manual. Check for binding or misalignment.
5. Lubricate the under head of the bolt and the bolt threads with ARP ULTRA-TORQUE FASTENER ASSEMBLY LUBRICANT. Then install the bolts into the main bearing housing and tighten them hand tight. ARP recommends using the ARP ULTRA-TORQUE FASTENER LUBRICANT that is provided with each kit as opposed to motor oil. This is due to higher friction on the bolts as well as inconsistencies in the clamping force of the fasteners when motor oil (or low quality lubricant) is used.
6. Following the manufacturer's recommended torque sequence, tighten the bolts in three equal steps to 50 ft-lbs with ARP ULTRA-TORQUE FASTENER ASSEMBLY LUBRICANT.
7. When changing from factory fasteners to high-strength fasteners, clamping force and tolerances will change; therefore, it will be necessary to check the main bearing bores for proper size and out-of-round condition after installation of the bolts and align hone the cylinder block if necessary. The main bores should always be align honed using the same fasteners and lubricant which will be installed during final engine assembly at the recommended preload.

Installation Method for Porsche Rod Bolt Kit

Part Number: 204-6301
Application: Porsche 996 / 997 / 986 / 987 (M9) Cap Screw without Washer

1. Please check the part-number(s) for your application against the part-number(s) listed on the instruction sheet.
2. Make sure there is an adequate chamfer around the bolt hole on the connecting rod cap to clear the radius under the head of the bolt.
3. Use ARP Ultra-Torque Fastener Assembly Lubricant to lubricate the threads of the bolt and the under head of the bolt. Then install the bolts and tighten them hand tight.
4. ARP recommends using the STRETCH METHOD when tightening rod bolts. Following the instructions for using a stretch gauge, stretch the bolts to .0095 - .0100.
5. If you do not have a stretch gauge, torque the bolts to 45 ft-lbs using ARP Ultra-Torque Fastener Assembly Lubricant.
6. The connecting rods should always be re-sized after new rod bolts are installed.
7. A log should be kept on the original non-torqued length of each bolt. Bolts that have any permanent deformation or have increased in non-torqued length by more than .001 in. should be replaced.
