Hi everyone I'm fitting a bigger turbo and really need to change the alternator for a smaller one with the same or more power output any ideas as to which one will fit with the least amount of modifications ?
Regards john

I remember there being a Nissan one that fitted. I think it was mentioned on Rennlist

Nissan Quest alternator fits apparently, whatever that is. Alternatively removing the aircon compressor frees up some room to lower the original alternator using the mount from non aircon models.

I have seen an "aircon delete" bracket marketed in a few places. Anyone know if this is any different from just fitting an OE alternator bracket from a non-aircon model? And is there any advantage over just removing the aircon compressor?

So you don't think you're over doing the bigger turbo just a bit?

AFAIK the non aircon alternator bracket works fine and a used one is cheap.

That's it ! So someone has done it before !But I'm struggling with the inlet manifold and getting the 2foot exhaust down in front of the bulkhead also I think I might have a seeing where I'm going issue (hasn't mattered before!)

I've swapped the brackets on mine to delete the AC plus I'm currently considering changing the alternator for a smaller, lighter unit. Lots of Japanese cars seem to use a design that would be ideal (later Nissan Micra for example) but it's probably going to be a case of taking a punt on one and making it work...

Certainly though just relocating it frees up a lot of space around the compressor area!

I'm going outside in a bit to continue moving the alternator, the plan is to fit an original non a/c bracket without completely removing the alternator.

No that the bracket is heavy but I did notice a Lindsay racing air con delete bracket on ebay for £65 which looks like it would bit lighter if you are on a weight saving mission as well.

Is it bolt on turbo? Had custom engine/turbo mount on mine moved turbo lower and didn't need to change alternator. With 4"/3" induction

Well the genuine non ac bracket works fine however you will need to use two longer bolts as a pair off the ac bracket are much shorter and the non ac bracket is much thicker. Also there are a pair of brackets that bolt to the brackets, when using the non ac bracket thought I had to come up with a couple of spacers as the brackets wont sit flat on the replacement.

Depending how much you intend on stripping down the engine to fit the bracket the rear bolt can be a PITA to remove.

It's a Lindsay racing turbo and Maf kit including injectors hopefully 350bhp when done ,had a look at the quest solution but the alternator is from a American van and not easily available in the uk ? So I'm looking at making a special bracket for a Yaris unit which is tiny 90amp and has the correct pulley .i want to keep the air con .
