Alternator Relocation Version II

As you may of recalled from one of my previous post regarding the alternator relocation.

I used a Mazda 3 alternator to move the alternator to under the inlet to free up room on the exhaust side for big turbo things! 😜

Useful information;
Mazda 3 alternator part number: A3TJ1091 110A 
Mazda 6 alternator part number: A3TG1391A 90A

This required a new belt route, I retained the OEM tensioner which you can see below and it worked well.

But on the built 2.5 engine I’m doing I wanted to tidy this up & make the routing far simpler.

I hunted for a eccentric tensioner with a similar size to the OEM units to go in place of the lower idler pulley that is used on NON-AC cars.

I found a GATES T38231 to be the perfect fit. You can get much cheaper tensioners but I’ve always had really good luck with Gates products, you need to fit a small washer behind the tensioner otherwise it will catch on the timing cover where there is ribbed section. 💡

I’m planing to get a bulk of these tensioners in and modified so you don’t need to run the washer and provide as a kit including the alternator bolts & belt, let me know if this is something you guys would be interested in?

The belt I used was a GATES 6PK1470 It’s a good fit and you need to slide it onto the water pump last, otherwise you will struggle.

The end result is a very tidy setup.

You can see it’s a big improve over the old setup I had and makes thing a lot simpler & cleaner install.

It be great to hear your thoughts on this! 😃
