I've had sequential, non sequential, 62-1 and a T-66 on all different FDs.

I really enjoy sequential and also enjoyed the power of the single turbos. My single turbo FD was 10 years ago. I was never really happy with the power output and spool of either.

Is there a new badass turbo out there that everyone is blown away by haha?

I won't run racegas so I'll only be running it at the max safe psi on 93 octane which I'm guessing is 16-17ish? I'd like to make as much power as possible, any way to make 500rwhp at that psi?

Is there a turbo out there that can do this and when would it start coming into boost?

Or if you guys can suggest a turbo that is just a blast to drive and has outstanding characteristics I'm interested.

Thanks!

EFR 8374 is the new hot turbo.

You will see what I mean when you look up the videos on Youtube and then see the power numbers. Very good spool for 400hp+ on the boost you want to run.

I've got the baby brother EFR 7670.

500rwhp on just pump gas. Have you thought about a built LS V8?

400hp or rwhp at 16psi? The t66 was doing that on the original stock motor.

I mean the stock sequential twins at 16 psi might make 360rw...

Looking to make some power.
Guess you havent seen my thread on v8s, im not a fan in a japanese rotary designed vehicle. Thanks for the help

As mentioned the EFR units are the latest hit. You can read more about them in our blog( see links in signature.

Yes- with crap spool/power band.

EFR 8374 you can do 400+ on pump with more torque at 3,000rpm than the stock sequentials at the same boost.

Like I said, watch the videos that show the response of the EFR 8374 (and what a difference it makes to acceleration) and you will see the appeal.

In drag racing on my old turbo the V8 cars used to jump ahead when we shifted and I would reel them in/pass through the gear.

With the EFR I get the same instant hit of torque as the V8 when we shift, and then still get to pull on them through the gear.

Sounds like you need a turbo 3 rotor in your life.

If you do a 500hp single 3 rotor, it still won't have great low end torque because of the 500hp turbo surge line, but if you keep it above 4,000rpm it should be a monster.

If you did a 3 rotor on stock hybrid sequential twins at 500rwhp, then you could have a (heavy) monster with a really broad power band.

The 3 rotor is too expensive and too big of a project.
Car is set up now and all I need to do is switch turbos.
3 rotor will happen on down the line if I'm successful in life.
Thank you for suggesting the efr I will look into it.

Any more suggestions guys?

Not everyone can be using the same turbo

EFR 8374 or EFR 9180.

The technology behind these turbo's are best for street driven or track cars (power under the curve).

If you want shear power without any regard to spool times and what not, then even the old turbo's will do.

Turbo's are measured by absolute power or power under the cruve.

Pretty much everyone wants an EFR these days. Nothing comes close in response, and power under the curve.

The EFR 8374 is a bad *** turbo and currently probably the best fit.

I think the EFR8374 really would be the "go-to" turbo if only it was more affordable.....I mean, I would have it I could afford it, lol..

I would consider a go-to turbo, a good middle ground, good price/performance ratio that is within most people budget. Its not a go-to if 90% of people cant afford it, or are unwilling to spend that.

The EFR costs about $5k down here. Just converting full - race's price into NZD = $3726 NZD, not including shipping, or import tax's which will total another $1k+ on something that expensive.

Awesome turbo yes! The best rotary turbo!? Probably! Go-to turbo? Im not so sure about that.

unwritten-dinasty

EFR for sure. If you cant afford the EFR, Precision 6266 or 6466 are great turbos with good spool and can achieve your powergoals.

For 500whp it can be done on 93 but adding a water injection kit injecting 100% water.

If you want a broad power band I wouldn't use the 6266, The 8374 in terms of low end grunt is off the charts and pulls all the way through the powerband. It's like running a turbo with variable A/R turbine housing that has light weight wheels. I think the 8374 probably outspools smaller 55mm compressor wheels with smaller turbine wheels yet puts out more power than those. its a great fit all around. You also don't go into surge too band and stay on the map at upper rpms and flow for efficiency. its a great design and size that fits a rotary 13B rew engine.

My GT3574R doesn't compare, the first thing that makes you wonder if the car is a turbo or a supercharger is when you hit the 8374 in 1st gear the boost is there, typically on all other inconel turbine wheels you wait for a while and pray you get something by the end of the rpm range for boost.

On a budget the current go to turbos are the Borg Warner s360 and s366 both available for $575 USD each.

I'm looking at your previous responses and the fact that you're not a rotary fan so I've got to ask: Why even bother? It seems as if you've made up your mind, two people who I respect very highly are giving you spot on answers and they don't seem to be what you want to hear. Maybe that should be telling you something?

You can lead a horse to water, but you can't make it drink.

He wanted the "new badass turbo out there that everyone is blown away by haha?" but probably doesn't want to pay the price, thinking a v8 is cheaper.

Guys, take it easy on him. There's more than one way to skin a cat, and not everyone needs to agree with your opinions.

Is every FD that's not running an EFR an underperforming P.O.S.? I sure as hell don't think so

I'm very happy with my PT6466 setup. Along with an IRP ported engine, A-spec V-mount and A-Spec manifold, 3.5 inch DP etc I'm seeing very good response.

The turbo is ball bearing, air/oil cooled, billet gen 2 compressor wheel, 1.0 A/R hot side:

http://www.precisionturbo.net/news/P...r-Released/124

If I lug the engine at say 1800 rpm in 5th gear and floor it, I see 5 psi by 2000 rpm, 10 psi by 2500 rpm and 15 psi by 3000 rpm. Not too shabby for a turbo that supposedly can put out ~700 rwhp on a 13b

My setup will (should? lol) make 500ish at 20-22 psi on pump gas and water/meth injection with my AEM system. I've always been a Garrett guy, but I've been pretty damn impressed with these latest Precision offerings.

its not horrible, but the 8374 with the same configuration does that in first gear except it hits max boost by 2500 rpms in first.

I recommend not getting a ride in one, cause you'll want one.

yea, unheard of.

the efr 7670 hits 7PSI boost free reving.

So, it appears that reading comprehension may not be the best friend of some (wink).

OP is clearly not a fan of V8 swaps in the RX-7. He is simply seeking friendly & genuine input of the latest/greatest single turbo upgrades for the FD. I appreciate the inquiry myself since after 22 years of owning mine, I'm finally looking to go single myself.

For those on a budget, the BW S360 or 366 seem like a potential fit but prolly not at the HP you are looking to generate.

I like the Precision 6266/6466 series since if it is good enough for Rich's setup, then I'm pretty much sold.

The EFR 8374 appears to be the best fit overall these days, though, in terms of low end torque & spool response very similar to the twins, but with the significantly added HP and much broader power band at elevated RPMs. This is the turbo that I really want but will likely have to pass on for the time-being because...

If you are in need of passing emissions, the GTX3582R kit offered by RP in Garland, TX is the way to go. I'm currently in that boat living in ATX. Plus, I'm not willing to give up the creature comforts of A/C. If that makes me "high maintenance", so be it (ha). Now if I could only get Chris & co. to take my money and work on my car (sigh). But that is a topic for another day.

Anyway, I hope the varied responses are helping the OP, as well as others that may be curious about the same. Best wishes in whichever single kit you ultimately choose.

unwritten-dinasty

I was the first to mentioned it and i will say it again, to not break the bank, 6266/6466 best damn turbos bang for the buck (awsome power and good spoool, BW S366 WAY too laggy).

OP, i think with a 6266 you would be pretty happy.

Surprised that nobody has mentioned the S362 FMW

s366 is a little laggy but is sure does pull nice.

Keep in mind that my opinions all happen at 6000-10000ft above sea level, these turbo's that people are talking about are super laggy up here. We are stuck with a catch 22, we need larger turbo's to make any power, but at the same time the thinner air gives you less spool up, so you really need to good medium to larger turbo with excellent spool up.

This is off topic but Rich did post a big engine pic so I'm allowed to study it as its a very nice looking engine bay.

Rich, what is the little tube I see on the intercooler piping above your BOV. At first I though maybe water injection, but it look like both sides are connected to the same pipe? Am I seeing that correctly and if so, what is it?

Looks like they are boost reference nipples that were one time used and now are just looped/capped.

What strut brace is that? FN awesome!!
