One of the challenges of installing an SR20DE or SR20DET into any chassis can be finding enough room to use the stock SR alternator. In the case of a Datsun Roadster, the stock alternator and bracket would hit the frame– a solution for this problem needed to be found!
After much research, a 1985-1995 Subaru Justy alternator was found– this is about 2/3 the size of the stock SR20 alternator, and with 55 amps of output, still works great with a EFI powered conversion– with enough power left over to power the rest of the car.
This conversion kit allows you to install the Subaru Justy alternator onto your RWD SR20DE or SR20DET engine mounting the alternator high and tight to the block– you won’t find a smaller setup on the market for this price!
Our kit includes the mounting bracket, a modified (used) water pump pulley, 6061 aluminum pulley spacer, a new OEM Honda alternator belt and the mounting hardware. This kit is laser cut and TIG welded from mild steel and is sold in a raw finish.
This kit has proven to be popular with people putting SR20-series engines into just about anything– we have sold them to people building Lotus 7 kits, MGB conversions, or just about anything else that this awesome engine has been installed into!
Price is $255
