I have a stock ported 13b RE with non sequential stock cosmo twins on it. Everything else is upgraded (fuel system, exh, IC, EMS, Ign, the works), so what is the maximum pressure I can push out of the twins without becoming too horribly inefficient or causing extremely premature wearing of the turbos?

I would assume that it is the same for seq and non-seq twins but if not maybe post your experiences with both. If you have power #s it would be awesome to see what other cars have made with these turbos.

Thanks!

 

I have this setup except that my engine is ported. Actually it boosts 11 psi, but the car runs way too rich. I guess you can boost about the same as with fd twins. Something like 15 psi, maybe a bit less since they are smaller.

 

I am now running 11-12 with no increase in air temps and only a slight egt increase (now running about 700 *C).

 

I have some FD twins for sell for $70 plus shipping. I got them for my cosmo but I'm gonna leave the stock turbos on until I get use to them (I'm young havent driven too much boosted cars)...

 

Well I have a 60-1 turbo that i may put on, but Im just trying to get what I can out of the twins. I am very impressed so far.
