hey, I have put a single turbo on my third gen. which has left me with these twin turbos....My next project is going to be putting a honda b16 into an old mini. I am turbocharging the honda motor and I have been looking at the gt28rs, but I was thinking....it would be baddass if I could get the twins from the rx7 to work on the honda motor. I would leave it seqential and I would have no trouble making the header or boost tubes. I know it would be easier to just put on a single turbo, but I would like to try it out. If anyone has any input, ideas, or objections about how I could do this it would be greatly appreciated.

P.S. sorry about where I posted this, I didnt know where else to put it

 

i would say do it, but do it non-seq and by the way, good choice of chassis there!

 

Stick with the GT28RS. You'd be getting into way too much complexity with the FD twins.

 

You would want to connect the exhaust headers of the honda to the exhaust manifold of the stock turbos, for starters. And locate the solenoids, and some sort of ECU to control them, etc. Probably not worth it, especially for an engine without the RPM range of a rotary.

Just start with the piping - I doubt it'll get that far.

stay with the gt28 because
-more reliable
-flange support more turbos than the fds

 

I had (just sold it today, now I have more money to drop on the 7) a crx with a B16a and the redline is 8000 rpm stock, so I would have to say the rpms are there. I dont rev my FD past 8000 rpm. Or maybe you mean somthing else when you say range?

 

it would have the rpm range, just not the exhaust pressure. thats one reason I would leave it sequential. If i ran them parrallel it would take to long to spool

 

Trying to run them in sequential mode in a car that's not an FD would be a MASSIVE chore. The stock ECU has to control all the solenoids and actuators that make the sequential system work - you would have to have the stock ECU to run the sequential system, then somehow fake it out about there not actually being a rotary engine in the car. That would be FIENDISHLY complicated to even make work, let alone work well.

I'd sell the twins and use that money to buy some other toys .

That does make sense

 

i think that I might be able to make it work with pressure activated switches and some solenoids, but then I still dont know if it would work well enough for it to be worth it. I just remeber how good they felt in the rx7 and I want to feel that in the mini. If anyone has anymore ideas on how to make it work please reply.

thanks

 

What solenoids are used in controlling the twins? I know there are a few vacuum/boost operated actuators, but what do the solenoids actually do? Thanks,

are there any optomistic opinions?

 

 

They control the air going to the actuators.

Take a look at the vacuum hose diagram.

 

Forget it.
