Thanks buddy. Appreciate that. I likely will make another thread at some point with more lengthy details. But at this moment they are out of stock and I expect them to be back in stock HOPEFULLY in less than a week. Latest order appears to have been caught up in a backorder situation. They are $45 shipped to paypal rob.rbturbo@gmail.com though if interested, and there is more info about tech on n54tech.

By the way, how do I get my hands on your PCV fix and what is this discounted price on turbos you speak of?! haha. If you don't mind, could you shoot me a pm please!

If you have recently ordered you are still probably stuck waiting as well, I think, but glad you are happy with the RBs!

Terry helped me alot on getting everything set up right but once its tuned in, the car turned into a absolute beast!! STILL NO WASTEGATE RATTLE WHATSOEVER!!!

Replied sir!

Great question and thanks for the compliment. I've always just try to be cordial yet factual. It can be a tough crowd out there sometimes though with a lynch mob mentality. It is a shame because we all have much to learn from others.

As for the product and revisions. Not many. The actuator ends I started making my own, I didn't like the source I was working with on them and felt the materials were cheap. After the first maybe 15 or so sets I started using Step Gap seals, although I don't think they amount to much at the end of the day at least I can say they are used. There has been some changes in the machining processes, but nothing that should affect performance. Overall its the same wheels and internals and materials that have always been used. I've used these combinations of wheels in past lifetimes (with other platforms) and they are a great match for an engine like the N54; I just didn't want to ruin what I know is a proven combo.

Can you give us a quick rundown of how your product has improved from the original version?

Thanks

I believe the N54 map sensor is limited to about 21psi but that is pushing it. These turbos can be boosted much higher in the midrange but at high RPM the housings and wheels get tapped out much beyond 19psi. Ideally Id say a midrange 23-24psi tapering down to a 18-19psi redline would be the way to get as much as possible out of them. Just need the fuel and tuning to support that obviously. A 20psi to 17psi tune though should be pretty smooth sailing, at safer ends of the efficiency ranges.

Welcome aboard. Curious, do you have any overlay of the stock vs. your upgraded t4 wheel for the efficiency map?

[Tiago@VRSF]

Welcome! Great to finally see you on here

[Rob@RBTurbo]

Not my specific map, pretty sure I never located it and MHI is not much on releasing much data. You can kind of improvise with the 13T and 16T maps- they are easier to find out there. If I dig it up though I'll post it.

ur turbos were installed a week later I needed anew axle then a week after that I needed a new transmission Dat power

[Rob@RBTurbo]

Sorry dude! Either bad luck, bad roads, or harsh driving! Not sure if its all about the power haha. But, that's the name of the game sometimes!!

Bad luck yes
bad roads no
harsh driving hell yess
Power yes
E93 yes
doubt anyone has an RBd e93.. I guess pushing the extra weight takes its toll but absolutely love da power.

Just curious, no worries on digging one up.

[mithiral67]

Mine went in last week, waiting on tuning from ptf. I have dyno time at the end of next month when the maps are complete for results.

Welcome Aboard!!!

[Rob@RBTurbo]

Thanks much! Means a lot from you ST warrior guys. Mad respect for that path, and it's a super sexy setup.

Good to see you here with official vendor status.

I've had my RBs for over a year now and the car drives very well with them, together with a dedicated map from ProTuningFreaks (20.6 to 18psi on 98 octane gas, for the record).

Welcome & Congratulations!
I purchase the RB PCV valve and their great compared to the oem.

What is the powerband?

spoooling from 2000RPM?

[JamesM3M5]

Nice! Can't wait for my stockers to go out so I can upgrade, but then I'd need a better clutch. And Flexfuel. And upgraded rear suspension and diff. And...

[JETmn]

Any plans for an upgraded N55 turbo?

Look around there is plenty of info.

[poloace]

Hey rob- id be interested in forum pricing too! Welcome. Glad to have you!

Basically, the car takes off at 5000RPM and the powerband between 5000-7000RPM is much better. Until 5000RPM you can achieve similar power with maxed out stock turbos (however, the IATs on stock turbos will be much higher requiring the use of methanol - so again RBs also have an advantage until 5K).

About the spool: Keeping the low-end torque was one of my top priorities in choosing the RBs. You can make the car feel *almost* like with stock turbos but you have to employ some tuning tricks at low RPMs, and your wastegate tuning must be done very well. I made huge progress on RB turbo spool from the first maps after I had them installed until the latest map iterations with my own ATR maps. I am at the point where I am *almost* very happy with the low-end torque.

I would say more power from 3000-7000 although I shift at 6,200.

Hey Rob, couple questions. Since you're local, do you have a shop and do installs? Or just primarily a machine shop of some sort? Also, curious about this PCV. Is there a link about it? Any benefits to a non rb turbo'd car (stock turbos)?

[Evolution Racewerks]

Welcome

We've installed quite a few of your turbos for customers and they were all very happy. Awesome product you have!
