87 Toyota 4runner is a 70 amp alternator, part number 100211-7570. 87 Toyota pickup is the exact same alternator

CS130 puts out 105 (stock) good power on the low end for street but not a good choice for racing, small bearing in the rear has always been a problem, you sure don't want it on your race car. CS130D (D is for double internal fan) is a much better choice for street, and race, it has a much better rear bearing (and probably front depending on alternator) and double internal fans for street. Makes it stay cool a lot better.

A good Denso is your best choice, and better yet their new style Hairpin alternators are just amazing
