And thats the TLDR version of why my car has a turbosmart actuator. Also, with that (low) actuator good luck getting much more than 15psi without running enough preload that your runout of actuator stroke and the flap wont open all the way. Then you either need to step up to the turbosmart dual port or a higher spring normal actuator.

Bitchin' thanks Leafy. ![Biggthumpup](https://www.miataturbo.net/images/smilies/biggthumpup.gif)
Amazon.com: Turbosmart TS-0620-1143 IWG75 Borg Warner Twin Port B1 Twin Scroll 120mm Rod Internal Wastegate Actuator Black 14PSI IWG: Automotive
I'd consider buying and trying it if it was prime eligible and I could get it by tomorrow. I already have the 4 port EBC to go with it.

</p><p>How is that for a price on the 4 port mac valve?</p>
</p><p> You recently sent a request for pricing of a Mac valve # 46A-AA1-JDBA-1BA. The current price is $ 32.55 each. We do not stock this item. <br />Delivery is about 5 to 6 weeks. Please let me know if you have any further questions.</p><p id="41">

Alright, so I found some little volt meter thing in my garage, and did a bit of testing.
There is power being supplied to the soneoid.
I also removed the MS unit and checked the db37 plug: the correct pin is being used for the EBC, and it seems to be soldered decent.
Next I'm grounding the ebc wire from the solenoid and listening for if it clicks per Rev's suggestion.
if it doesn't the solenoid is defective.
if it does there must be a problem with the MS unit.

Just buy it now and get it over with, you don't want my other actuator, trust me.
What it I told you that a T25 flange 0.85 A/R IWG turbine housing existed for the 6258? For reference, current turbine housing is 0.64 A/R.
or would 4port EBC + 2 port IWG actuator + 0.85A/R housing = Honda power?
Instant spool sounds fun, but always always always being in boost kinda sounds like a pain
I mean, if it turns out that's just how this build decides it wants to be I can deal with it. I understand I have ALLTHEFLOWS and its not like its a huge turbo, plus ye canne change the laws of physics.
Another thing: why do we ALMOST NEVER see companies talk about the fact that this turbo indeed does creep on a miata?
Gotta admit though: it does sound really cool and it does hit boost really early on. Goes from vac to boost in an instant, literally with the movement of the throttle.
This setup is gonna suck at gas mileage lol, it's always in boost![Party Kitty](https://www.miataturbo.net/images/smilies/birthday[1].gif)
