Here is a dyno graph of a 8374 borgwarner turbo kit with v-mount intercooler set up, 1000cc, 2000cc, hks twinpower and 2 bosch fuel pumps, this was on a stock motor with pump 93 octane. The car was tuned @ 15lbs of boost, I took the car out for a drive and I must say that I have tuned and driven T04s, To4r, To4z, GT42, Greddy T78, Gt35r and must say the Borgwarner efr turbo's were meant for rotary motor.

 

That's a whole lotta pump for that power/boost level

How did you like the boost response?

 

What ecu are u running?

 

Adaptatronics ecu, we will be switching over to E85 and running 30lbs of boost

 

Broad powerband. I like it.

 

Nice powerband! Be honest, how long did it take to make that compressor discharge pipe?

 

He had it express mailed to Japan, they knocked it out for him in 30 minutes

 

Actually it was pretty easy once I figured out the degrees to cut! We are going to change that in the spring for more of a straight 90 degree

 

Hero! i have almost the same setup.. still getting the car finished
i have a single gts450 walbro, efr 8374 1.05 ewg, dual wg, custom equal runner manifold, 3,5"dp to 3" exhaust, cx racing LIM and aem smart coils.

could you describe how the car is to drive? how boost is etc.. i'm all hyped up and cant wait lol

 

I've driven and tuned rx7 with, Greddy t78 & 88, Gt42, GT35, To4Z, To4s, Apexi and I have to say the Borg Warner turbo are the best. The boost response is great and I really enjoy this set-up, I would recommend these turbo to everyone. The only drawback was not hearing the turbo spool, you can hear it a little but not like the others.

 

^ Was your setup EWG OR IWG?

 

Iwg

 

so boost lag is pretty much non existent right?

 

Yes! pretty much best turbo for FD
