need to make a post on my trans. bought it new. maybe i can get a buyer and get a built auto. id be super happy.
Dipp's 74mm @ 38psi (with auto tranny) did 615WHP on a Mustang and trapped 146mph. So I guess it's not really an "800WHP" setup...

Yeah, all the S400's should be the same size, right? Basically GT42R sized? I really like how the PTE 6466 and 6766 are so much smaller physically and still flow 90+ lb/min. I could swap either of those in no problem. Trying to wedge an S400 in would be more work.

i got the 67mm thinking it would spool the best out of them all. with the textended tip technology and the billet wheel.

Why a single 6766 is good for 1000whp...

I'm happy with my 65 lbs turbo so far but its getting pretty boring @ 15 psi. I think mid 20's boost will bring the smile back for me. I can't mess with any of you big turbo guys.

Unfortunately that's the range where Subaru's start to explode.

You can get the Precision turbo's with a large variety of housings. Single
scroll or twin scroll T4 are available.

I don't really like the feeling of having a turbo that's not being pushed. That's just extra lag. I hope to push mine a little more someday. Or I guess I could get the 6466 or 6766 and run similar boost to what I have now. I just wish Subaru's like higher boost. I'd love to just crank mine, lol.

i think in time subaru will step up more. I agree the blocks are really a hold up to huge power. Im going to try p and l's block mods shortly and see if i can get to the 40 psi area. if not ill stay on my sleeved block and be in the 33-38 range

How do we know they don't like 30psi+ of boost? I don't anyone has been willing to push the subaru motors other than P&L. I wish I had a better motor

I want to do the same. My next block will have the P&L block guard..

I think we should look into the cheap and available H6s. Like the guys overseas..

funny you say that. i have been on ebay and the net trying to find an h6!

and yeah p and l doesnt give much info but they seem to be running those modded blocks hard.

i coated my valves to help with heat and knock. hoping to let the boost run wild.

Agreed! Not necessarily the tuning expert here, but with the subaru 4eat's there seems to be significantly more drivetrain power loss than the manual set ups. Even with a fully built 4eat.
Hence my comment... 800 awhp "capable" is very different statement than achieving 800 awhp. I also agree, because of this, there are very few subaru's in this category.
My setup is probably 500 awhp "capable", but i'm not actually making 500 awhp.
Therefore, I would never advertise as making 500 awhp...
