LS1 Alternator Conversion Kit for Nissan SR20

Ditch that tired SR Alternator that is almost 3 decades old and step into a world of reliability. The alternators on the Nissan SR series engines came with an output of 70-90Amps. The LS1 alternator itself are 1kg heavier when compared to the OEM unit due to the extra windings to produce a higher amperage output but overall the complete kit including the block bracket, adjuster and hardware are 1kg lighter inclusive of the 2kg weight saving of the PRP kit over OEM.

With today's technology and horsepower figures being constantly pushed, an average street car can easily consume even the full 90amps by making even the most minor modifications such as, Aftermarket ECU's, Additional Fuel Pumps, Upgraded Ignition Hardware or even a simple set of headlight upgrades.

Platinum Racing Products has specifically designed this kit to eliminate the requirement of both alternator bracket, conversion bracket and the rusty old engine block bracket when upgrading to LS1 Alternators. Our kit comes fully integrated with a new 5 axis machined billet block adaptor bracket and the adjuster bracket making for super simple and amazing looking installation which mounts the alternator as close to the block as possible.

This kit can be installed in a short amount of time with ease and comes with:

• PRP Custom Billet Alternator Bracket
• PRP Custom Billet Block Adaptor Bracket
• Adjusting hardware to suit
• 20% Under driven Alternator Pulley to suit SR 5 rib belts
• Optional LS1 Alternator (either OEX or Genuine GM/Mitsubishi [GM92058857])

*When you select the colour we assume you want the block adaptor, adjuster bracket and pulley the same colour. If you need a custom colour kit please leave a note in checkout*
