Anyone know the "a/r's" of this Mitsu turbo?
I just picked up a td07-9. Some people say they are like a greddy t-78 but that's BS. I have a t-78 on my rx7 and it's much larger than the td07-9.
I'm trying to figure out if my 2.0 prelude can handle it. It's one hell of a step up from the nissan t25 I'm running. I'm building another engine on the side for higher boost and I'm thinking about using the td07. Ideas? |

Nah?

Re: Anyone know the "a/r's" of this Mitsu turbo?
I am unable to locate a/r's for the housings of the tdo7. MHI uses cm^2 instead of a/r's. I did find out that 6cm = .41 a/r
7cm = .49 a/r 8cm = .57 a/r I think a 14b has the 6cm turbine housing. Supposedly mitsu turbos have such efficient turbine wheels they can get away with smaller housings. Anyhoo, I don't know the "cm^2" or "a/r" of the tdo7 so it would be a huge gamble since I would have to fab a new manifold with a t4 flange in order to run it. Here is a link that compares the td07 to three other turbos. I was unable to compare it to my t25 since it's on the car. The t25 is .42/.48 from what I understand. The turbos pictured (left to right) are 1. Huge cummins unit for my "jet engine" project 2. Greddy T78 for my rx7 3. Td07-9 4. One stock Hitachi ht-12 from the twin turbo setup originally on my rx7 http://webpages.charter.net/7heath/t...ed%20to%20t78/ I threw the big one in for fun. The ht-12 is smaller than the t25 so maybe that will help with size comparison. The t78 has a much thicker turbine snail than the td07 as shown. Hell the whole thing is much larger. So, whatcha think....can a built 2.0 huff enough at under 7k to run this thing? |

If it does spool at 7K on a worked motor itl be insane..

Well now the link isn't working.
