I was thinking of going single, but I don't like the lag of the big turbo's. I was wondering if I could buy two Apexi rx6 turbo and get a custom manifold made along with a down pipe and all the other parts, and run as a twin set-up. How much horsepower would this set produce for an FD. Your thoughts please!

Project RX-7

1 RX-6 will get 400RWHP @ 15-17lbs of boost (correct me if im wrong). But i have no clue what 2 could do......

maybe 500RWHP+ ?

YOu will have to see if the turbos will fit into the stock turbine manifold.

I think a settup like that might produce serious lag.

no I said I would have too see if i could get a custom manifold made and a street port will have to be done.

Have you ever been in or driven a single turbo 13b? I suggest you do one or the other before wasting thousands on a complex twin turbo system. The lag is NOT that bad.

I agree...you should actually drive a single turbo 7 first before you make an assumption about lag. Not saying that you can't make the manifold but it will be expensive. Custom manifolds like that usually run 1000+ even the FEED manifold is like 1500 and i'm not sure it has the same flanges that the IHI use.

400 rwhp is a fassssst Rx-7. What a rx-7 does with 400 rwhp takes a supra 600 so don't think let that number fool ya. Our cars don't need a hell lot of power to be fast as hell.

dude, youve got bigger problems to asses before even thinking about turbos. for example, running an intake, downpipe, midpipe, and cat back, on a stock ECU!

its people like you who give the FD an "unreliable" title.

No i don't have bigger problems, I have the pfc install aready with an upgrade fuel pump.
thanks for the concern's, I guess I will have to go single I thinking
of t78 or t88. yes I have ridden in a single turbo to4 and t78. I was just have something different than what everyone else has.

JoeD

good...cause that wasn't in your sig.

These turbos are very good choices. That may be the reason you see so many using them. Different is cool, but also having s setup that is known to be good may produce less headaches.

You have the wrong idea here... The stock twins spool very quickly because of their size, they are very small. Putting a single turbo setup will give you some lag... full boost by 3500 on the rx6?...but you cannot bolt 2 rx6 turbos to the stock manifold, and if you made a manifold, it would only increase the lag even futher... You would need a heavily ported motor, street port is not enough to run 2 rx6 turbos. And just because you add another turbo, doesnt mean you will make twice the power... The turbos will be able to support more power than one, but running two will not decrease your lag of running a single turbo.

zyounker

Um, NO.......


If you want less lag then a single turbo, why would you think running two of them would make it spool faster???????????


The apexi rx-6 is suppose to be a great turbo where you get full boost by ~3-3.5K.. Where do you want boost by???? How much RWHP do you want?

A t04 60-1 1.15 A/R will spool about as quick as the RX-6 and produce a little less horse power... the RX-6 is a medium/large size turbo, that spools very quick..

Dude the Apexi has same or less lag than stock setup, what the hell are you asking for? Dual RX6's wouldn't really solve that ;-)
If it's more HP, thats understandable, get a T04r or some other t04 setup if you want more hp.
Or you could take a look at my VATN turbo post, very interesting yet still seem in somewhat baby stages.
