Well i've just recently tried to dyno tune my 13B-RE extended street port, with the mitsubishi TD07-18A, mostly just to see what this turbo could do, I bought it nearly new on ebay a couple years ago with hks log and hks wg. With the hks wg and 7 psi spring the turbo makes 15 psi with my profec spec b 2 controlling the boost. The worst thing I have to say about this turbo is that it runs out of breath at 6k and boost drops to < 4 psi, which in a rotary is just not acceptable.

Thought I'd share this for anyone who see's any of these turbo's cheap and thinks they want to give them a try DON'T! Stay away from the 18A the compressor inducer is tiny and the turbo is not efficient past 6k on a rotary. The 25A/G are much better and can make 20 psi til redline.

 

My TO4s does about 400hp at 14psi with similar setup. Is your hks divided? Find a TO4s, GT 3540, or .....

thanks for the good info.
I'm working in Langley and I saw white fc on 200St many times..

BTW How do you pass aircare with single and microtech?
I have red FD and about to go with single(t04s) and worried about aircare..
also you go to Forcefeed ? for dyno tune?
I think I'm gona buy microtech from him..
good to see local rx7 guy on the forum..

my fd is off road now but soon will be back..

 

The 18A wheel ist realy to small for Rotary. Greddy sold the TD-06-19C (which is way larger as the 18A comp) as an entry turbo for Rotary rated at something like 330-350 hp, which are still not compareable to 25G compressor which is able to push up to 500 hp on Rotary. You will be happy with a TD07-25G.
On Mitsu Tubos, not only the series with exhasut size das matter (TD06, TD05, TD07) but more the compressor size (20G, 25G, 19C, 29D, 33D, 34D etc)
