Ive been looking all over and i cant find what size APS uses for theri turbo and twin turbo set ups....does any one know...they look like 16 or 20g's but im not positive. i am thinking about going turbo but cant decide between singel or twin...plead your case so i can make my decision easier...thanks

 

I don't remember the exact size of the APS turbos used in their TT kit, but it is not a mitsubishi turbo (meaning it is not and "g" size as in 16g or 18g). Their turbo is a Garrett turbo that is custom spec'd for APS, but I will let someone else tell you what turbo it is sized close too, i just can't remember. But they are smaller than 18g's which are what are used on the Greddy TT kit.

 

The APS turbo is a GT35 series, water cooled, ball bearing unit. Very nice piece.

 

Thats for the single turbo though right? What were the sizes of the twins again?

 

The APS TT uses two GT35/28R turbos, custom made for this kit by Garrett.

I am not sure what the APS single uses, i'd have to check.

 

I believe APS use twin GT25/35R turbos with their out of the box TT kit.

GT25 turbine with a GT35 compressor not the other way around.

Dont know the exact specs with regards to A/R etc.

Peter mentioned the turbo size in one of his old threads when people had asked about it, i'd have to find it again.

 

It has been mentioned by Peter before and I believe its been GT25/35, if it is GT28/35R now then it has changed.

Here are two articles off the APS website which mention the turbo sizes.

Replace XXX with air power systems.

 

Well, apparently I am wrong. I thought I had seen Peter say that somewhere, maybe I was mixed up.

 

The aps turbo are not mitsubshi turbos so they are not measured by "G", I would guess the aps turbo is around small t4. Its a garret custom turbo. Greddy uses all mitsubshi turbos. Did you know that the srt-4 turbo is a mitsubshi turbo, the srt-4 engine is very similar to the 95 eclpise!!! Quick fact!!! lol

 

i knew they werent G's but i just compared it to those for the simple fact that i know abut those cars and those turbos more than any other just b/c all my friends have EVO's and thats all we talk about, i was just thinking of something comparable
