Motor Sport Parts

This 2mm spacer ring allows for a much easier setup when retrofitting some differentials and or crown wheel and pinions within the 915 family.

Note
Longer ring gear bolts may be required

Our spray bar, made from stainless steel, is an excellent reproduction of the factory RSR spray bar. It allows for gear lube (presumably from a remote pump and cooler) to be returned directly to the gear mesh, including the final drive gears.

** This requires machining to the front "nose cone" housing.

We have updated our 915 spray bar kit to include an improved oil return port that will not interfere with the torsion bar tube and allows for better routing of the oil return line.

Fits all Porsche 901/911/912 aluminum case transmissions.

Precision machined from 4130 Chromoly
Better supports both main and pinion shaft bearings
Improved design captures the main shaft bearing 45% more than OEM
Substantial clearance provided for even non-standard tall 1st gear ratios
Perfect fit for bearings and assembly

The original Porsche 930 transmission differential side cover is made of cast aluminum, not to mention it's pretty thin.
Under load there can be a tremendous force applied to this cover, and it can break, sometimes resulting in a damaged ring and pinion-or worse.
Upgrading to a billet side plate will add significant strength and increased reliability to the differential section.

Our design features include:

A ring gear thrust bolt to reduce ring gear deflection under load
Ports that can be used for an oil cooling system
Cross drilled oil passageways for the differential bearing

Comes with (3) 3/4 - 16 O ring plugs.

We can provide bolt on hydraulic slave cylinder for your Porsche 911 915 transaxle eliminating all the woes that come with a clutch cable. It can be used for both upright and inverted applications - especially nice for mid engine conversions.

Includes clutch arm, cable clevis, slave cylinder, spacer, seals and our billet slave cylinder bracket with bolts. This requires the use of the 1978 and earlier clutch fork pivot shaft.

Note: This requires a portion of the rib on the bottom of the transmission that holds the original clutch cable to be cut away on 72-77 models. To go back to a cable configuration if one so chooses can be done with a bolt on bracket.

A 3/4" clutch master cylinder is recommended - not included.

The weakest and most commonly broken shift fork in the G50 5 speed transaxle is the cast aluminium 1st/2nd shift fork.
Our newly designed fork is CNC machined beautifully from aircraft grade billet aluminium and offers the most strength over any fork in the aftermarket. Our fork will also promote enhanced lubrication to 2nd gear as it better captures the idler gear when engaged.

Fits all G50 5 speed Porsche transmissions '87-'94.

This update will allow for use of the late style 915 main shaft seal and o-ring on early transmissions ('72-'75) where the seal installs from the inside and the guide tube is not removable.
The update is a also good repair for those whom have loose, damaged or worn out guide tubes.

** This requires machining to fit

The original is machined off and a custom steel tube is fitted. It's further retained from the inside of the diff case with a high quality snap ring and sealed with the factory o-ring.
