Last time I checked the leaders are Borg Warner and Garrett.

So they're only good if they build for OEM's? That's right, all OEM's ever care about is putting the highest quality part on the car, not the price or anything. Maybe Garrett has economies of scale, which I'm sure they do. Doesn't mean they produce a higher quality part.

Has nothing to do with having engineers and a proper facility to actually perform r&d.
Precision is backyard in comparison.
Just curious do you see any precision turbos in lemans or WRC ?
Precision has come a long way and have started making decent turbos but to say there the best in the industry is a joke.
Just last nite I took a PT74 off a car and put on a GT37 (which is only 67mm) and made 75 more hp. Precision for the win.

Sir Braps A lot
i run a HKS 44MM with no boost creep or problems, but if i were to build a kit again i would but a Tial kit that Jason caries. from the cars that ive worked on the Tial is flawless and gets the job done. also as Jason stated the Synapse is a great unit just a little confusing when routing, but you cant go wrong with any of the choices that you have listed.

i took the 50mm synapse i had off since 1. it was extremely confusing to use with an EBC, 2. the 2 halves separated and i had to send it in to synapse for refurbishing (great customer service btw), 3. i just wasnt happy with it.
like i said, Synapse has excellent customer service and they helped out a lot and explained to me in great detail how to use the ports, and all that jazz. it sits on my shelf now.
i went with the precision 46mm and it holds rock solid. i changed out the springs and i am running the 12psi setup (no ebc, straight off the compressor) and when the car hits the 12 it opens flawless and no matter how hard i run it, it will hold. i am looking forward to putting the EBC back on and letting Steve Kan finish off my tune with this WG. I am very satisfied with the precision kit and it is a well built unit. and i am not getting paid for this!!
i cant say anything about the Tial but a lot of people use them with no issues, so they gotta be good stuff too!

I used a synapse and it is not so good.
The piston is loose... and doesn't shut perfect anymore.
When you push the piston in you feel a point where you need to push harder... and after that point it slides bether.
I used an AVC-R at first and it was hard to get the boost smooth.
The I installed a Link RX ECU. Boost controller function off. It was stable.
But with the boost solenoid at lets say 30% duty cycle the boost was all over the place.
This is the seccond synapse in 3 years.
Now I'm going for a 44mm MVR.

I have a different experience with synapse gates. ...Had no problems what so ever and the car came with a synapse 50mm gate... put 11K hard miles on the car.. Held boost perfectly till I had an oil control ring failure. Previous owner put 15K on the car...don't know how hard he drove it..but I sure as well beat the crap out of it...
Now i'm runningdual synapse gates on my new set-up =-)

I might as well add JGS to the debate. I can only personally compare it to tial (only two brands I've had), but the JGS 50mm I had on my last car was very good build quality and solved my boost creep issues that the Tial 44 mm had (both use the same input flange). I personally like JGS over Tial. I also like that it doesn't use a diaphragm.

I have also heard good things about Synapse. Jason sells them with his kits on Rx7store with no issues.
With cost, Tial is American made. As such, they may be a little more expensive. Their customer service is top notch. I just did a spring swap on my 50mm BOV as the 10psi spring was causing surge. I mailed them mine and they sent me another for free. They even included a spare allen bolt.

You added a larger wastegate. Despite the flange, it will still have more flow. I don't see how this relates to the Tial not performing. Are they cheaper?

JGS used to be cheaper than Tial, but now I think the smaller tial MVR 44mm gate is ~$20 cheaper now. I asked a lot of technical questions and JGS got right back to me as well as sent me springs quickly, etc. So they have good customer service too.
Here's a link to some comparison pics: https://www.rx7club.com/single-turbo-rx-7s-23/50mm-jgs-wastegate-vs-44mm-tial-pics-894682/
Just thought I'd toss another gate in the mix; it's a good quality, high flowing, gate that few people ever mention on this forum. I don't have any issues with Tial (I have one now), but the JGS gate is better IMO.

That's my point. With the same flange as Tial, you can get a 50mm, non-diaphragm, American made gate. The piston also rises higher, and the body of the gate is larger, both of which I think helps.
