I need the starter on my 1993 NISSAN D21 PICKUP L4 2.4 Liter FI replaced. I want to have a friend install it and save some cash but I'm wondering which is the right one to buy. I go to the Advance Auto Parts website, click on all the right buttons identifying my vehicle and it gives me a list of starters and prices. But some are 8-tooth, some are
9-tooth, some are 0.8kw, some are 1.2kw, some are 1.4kw. What's the difference? Will they all fit my truck equally good? Also, how important is it to replace the inhibitor relay? Much thanks for your help.Regards, Nick
