didn’t want to pollute your turbo thread; I agree with your feeling about not choosing Pulsar/copy-cat turbos over Garrett, but it is worthy to note that according to Pulsar their turbine housings are directly interchangeable with Garrett and for someone considering a less powerful but more responsive street engine they do offer a 0.72 A/R T3 housing that I feel could serve this purpose.
.
Just checked out their page..... daym , they offer so many options for that turbo .....
They do look like reasonable quality and have some good reviews. I know at least one person that will use one so that will be interesting.
What I do know about them
*inferior turbine (cast iron?) housing material .G30 is cast stainless - although a downside to that is they are ridiculously heavy.
*Inferior turbine blade material
I know there's some pictures of the turbo at the beginning of the thread, but I wanted to add one with something that might be familiar to show just how impressively compact it is for the amount of power you get.
Next to it is a standard Starbucks Grande (16oz / 473.17mL) cold cup.
That's the recommended .83 housing.

That really is the crux of it .....for it's physical size.............. it really can't be beat.
well for sure a good stainless housing is better, but not really a huge deal on a street car imo.

Agreed . The big thing for me would be that I wouldn't trust it to fit properly . I've had a few experiences with Chinese knockoff products ..................
Also something I've noticed with the cast stainless manifold vs the old steel ones I made ..... they really do hold the heat in much better. Everything that can be done down there to stop heat getting to the LIM and into the engine bay ...is a good thing.
Kinda relevant, kinda not. You are using a backpressure sensor correct? Can you describe the parts and tubing you used for this? Just curious on what I am piecing together vs what others have used.

I've used a 90 degree stainless fitting- 1/8"NPT into manifold and 1/8" flared steel tube exit. From there there is approx. 1m of steel tubing leading to a point beside the ECU . It then goes to silicone tube and I have used the VFAD plastic reservoir as a pulse dampener/ moisture barrier . From there it goes to my gauge . I don't dedicate a permanent gauge to EMAP as you really only need to look at it when you are analysing your system performance. Plus, a lot of moisture comes through the line on startup which can damage the gauge sensor.
Well ... I had a heart to heart with my engineer and managed to convince him to............ maybe one day, if he's not busy ....do the low comp rotors .
Accidently turned up da bewst ... Still only 11.5ish on stock engine but damn ............ I'd forgotten how quick these things are! 2nd 2500 to 8000 ................3rd to 7500........................ zero to 11psi in 0.5 seconds in 3rd.

2nd to 3rd was with the turbine blade carrying momentum right?

Still 2500 11+ was only ~1.5 seconds 0.0
Yeah , and remember ............... you don't typically start from 2500rpm ... I just did that because I was tuning. At any rpm over 4000 the spoolup is much quicker.
It would seem now with the G30 that the 0.83 housing might be what you’d want to have with the latest turbo manifold to provide the best spool without the emap becoming too high.
