Yes, I have completely removed and blocked off the stock valve on my EFR. I utilized every built-in option the EFR has for simplicity.

Any help would be awesome! Thank you.
You are correct, the installer can block off the valve on the TMIC -or- block off the valve on the turbo. I typically prefer to utilize the valve on the turbo because it is so simple and redirects the vented-charge-air to the compressor inlet. but your call entirely.

Here are some photos from this thread of our kit with TMIC valve blocked off:

Geoff, I've stopped by your shop before(I live locally) and although I didn't get to talk to you directly, the staff was great there. Do you guys install the kits as well? Probably a silly question but I don't want to assume anything. I'm conflicted on the stock location vs. twin scroll/rotated configuration. I'm not sure how much modification is necessary to do the twinscroll configuration but was curious to see if you guys will do the work(when I'm ready).
Thanks.

hey thanks for stopping by Full-Race and checking us out. The choice between twinscroll and stock location really depends on what are your longer term goals? Will the motor stay stock or will it get built? Will you run mostly pump gas or mostly Ethanol?

We originally thought the stock location kits would be more popular than twinscroll -- Stock location is an easier installation, its RHD compatible and allows for most existing modifications to remain unchanged (TMIC, intake, etc). Surprisingly Twinscroll has been more popular... Twinscroll kits are more work to install, but still fairly straightforward and similar to most other rotated kits - requiring a PS hose modification. Typically we do not offer installation services. However since youre local, I might be willing to make an exception. email to [email protected] and [email protected] when you are ready and we can either give you a green light or refer you to someone else. thanks -Geoff

Please share opinions on the oil drain. Does not quite follow the instructions. But at the same time, the length of the oil drain is small and the cross-section of the tube is sufficient. Will it work correctly on EFR 7163? I also assume that the oil flow through the ball-bearing turbine should not be greater.
Thank you in advance for your advice.

it could have problems due to the welded 90 degree bend. it might work, the test is to roll a 1/2" ball bearing through the tube. if it doesnt get stuck you will probably be fine

Thank you very much for your answer. The ball rolls, but I also do not like the welded turn. Made from the fact that it was available, but apparently need to find a smooth turn and remake ...

Since I had to get the IWG actuator out of the way to replace an oil feed adapter, I added more preload when I put it back on. I am up to 7mm preload now... Before driving, I went in and made a new map to lower the WGDC and I got pretty close on the first try. The difference is pretty nice. It'll now hold like 22ish PSI at redline, but I am overshooting by a PSI'ish. I have 3 logs; 2nd gear, 3rd gear, and 4th gears (below):

This is about 6,000 ft above sea level on a .85 housing.

2nd Gear


3rd Gear



4th Gear


4th Gear with Target Boost and WGDC (not sure why Target Boost is jagged in the beginning as the map is not)

Thanks for sharing, yamaha. I'm about to add more preload to my IWG actuator also. How much have you scaled your turbo dynamics? I had to drop my proportional and integral TD tables down by A LOT with the dual port IWG actuator.
Any reason you start below 50% WGDC before boost threshold RPM is reached?

I don't get any better spool with more WGDC and I don't want to deal with spikes, so that's where WGDC sits.

I haven't adjusted TD in a long time, but I think I've taken around 30% out across the board.

Get one of these and a quick grip clamp.

You will also need to load the actuator up in a press or vice to take the spring load off the threads so you don't destroy them removing the ring. I found with mine that if you do that you can actually loosen and tighten the ring by hand and no tool is needed as all of the load on the ring is from the spring.

its hard to put it in vice with all the things sticking out of the bottom
but I'll give it a shot

and a special tool?? man, turbosmart is a real extortioner

I use these on this actuator as well as when I had a TiAL EWG....



You don't absolutely need the special tool, but it makes it easier. My collar did not just come off by clamping the halves together.

ended up using wise grips and put two pieces of wood to protect the actuator, the collar was tight so I used adjustment wrench from my coilovers



purple and pink... according to the manual it would only give me 14 psi
the table is confusing with the mix and matching, I want to run 2 bar peak and be able to drop to 1 bar for failsafe map

however I don't see a single 21psi spring in the chart

So leave the 14 PSI springs in... It is the boost controller that allows you to get higher than spring pressure.

I'd also go to 8-10mm of preload to make it work like it should.

I don't think I have enough thread to allow that much preload, possibly the actuator is meant for another frame
