hey i am a 93 fd3s owner and i have a new engine, and a rx6 single turbo, but i really want to break into some good times, and although i am close to done i have not taken it to the track yet, due to the fact i still need a new ecu and fuel systema and a fmic, i own a frankenstein fd, lol, newayz i have been hearin alot that the rx6 turbo is dissapointing in power, i was wondering if neone had ne experiance wit making a twin rx6 or twin ne turbo other than the m2 and such, like custom work???cost?? time??

 

not worth it dude, just get a larger single turbo, GT 35/40 or T78 for drag.

 

check out the single turbo section some guys are making close to 400 horse. not to many people though. if you want a 1/4 mile car get a turbo that is so big you have to lanch with nos or you will stall. J/k i agree with skunks get a bigger turbo if you like the quick spool try the gt 35/40. and the t78 for even bigger power with a little more lag.

 

yeah i know there are bigger turbos, by myself being a apexi fan would like to make more than 400 hp for drag, i really want a good time and i was wondering what i could pull with a rx6 turbo, i like that it spools fast, but im also really power hungry, u know gotta have the fastest thing around, and somthing unique is also what im lookin for, but thankz for the advice,

 

The Apexi RX6 is somewhat like the T04e - it's an alternative to stock turbos with a little more power advantage. I've heard of someone from Japan making 450 rwhp on the RX6 but most make less than 400 rwhp. It is not rebuildable in the states so if an apex seal flies through the turbo then it's around $1800 for another turbo. I'd go with the GT35/40 or even consider running the new BNR twin turbos non-seq - someone pulled 465 rwhp at 16-17 psi with these turbos - full boost by 3800 rpms - costs $2K for a set. people are creeping in the mid-high 400 rwhp with the GT35/40

 

if you want smoking fast and unique, V-8... enuf said

 

I dont think you would be able to spool both rx6's... you should have directed this question to the single turbo section as there are quite a few turbo guerus that browse it regularly.

Moving this over to the Single section, as those guys have a little more experience with the singles.

IIRC, the RX6 in Japan is actually a larger turbo than the RX6 we get in the states.

But like everyone said...it would be too much hassle to try and get twin RX6's to work, and your little 13B wouldn't be able to push them. Go with a good single setup like the T78 or GT35/40. If you must have twins, Border Racing makes a twin kit that uses Apexi turbos (each smaller than the RX6), and A-spec tuning is coming out with a twin Garrett GT25 or GT28 kit.

A-spec kit

 

I think it was Turbostreetfighter who had custom dual turbos on a drag car that were much larger than RX6's and he never stated any spooling problems. I don't see why this would be a problem.

 

Aside from the fact that he's running methanol, and it's a drag-only car with a really high stall torque converter on an automatic? I mean, really... that's sorta a different application

 

Hey, I got an idea...why don't you try out a twin RX6 setup and tell me how it goes.

Maybe I should clarify...his little 13B wouldn't push them very efficiently. Better?

i also built a street kit with turbos that are bigger than the RX6!! they would work perfect especially since theya re BB!! i say go for it! the street car makes full boost by 4.5k and is not BB. they will work especially since you are going to drag the car mostly.

I need to check this but I am pretty sure Ferrari F40's that came out in europe had 2 RX6 turbo's

2.8lt V8 and they have a very good power band.

I would go twin singles as well in the future, the only concern is lack of space, especially for right hand drive vehicles.

 

ITS THE WAVE OF THE FUTURE :-)

Yes rotational Inertia is a bitch !, only one way around it, smaller diameter and less weight of turbine/compressor assembly........how? = 2 x smaller turbos.

Now how to fit them You guys in the US have it too easy ! No brake booster, no steering box. Lucky SOB !

 

Huh, really? Dayumn... and here I was tossing around the idea of twin RX-6s for a 20B (yes, I know the manifold would be a bitch). Hum.

Damn you guys and your twins; I need more money. Someone help an NA brutha out? Or at least be near me so I can drool over your engine bay...

Seriously though, I've not yet found a map for the RX6s... is there any GT series that they're close to?
