Platinum Racing Products – LS1 Alternator Conversion Kit for SR20
As you know the Nissan SR series engines came out from the factory with between 70 and 90Amps alternators in the later model Rb26. With today’s modern builds and horsepower figures being produced out of SR engines you can very quickly consume all 90 Amps of the OEM alternators output. Dual fuel pumps, motorsports ECU, ignition system, modern headlights, and a set of fans need more Amperage than the OEM Alternator can supply. Ditch that tired SR Alternator that is almost 3 decades old and step into a world of reliability with the LS1 alternator, which produces 140 A and is the perfect upgrade for the SR Engine using the PRP conversion kit.
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. 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.
