Got your PM. I'm still curoius about the flange though. I'd like to see it.
You have my email.
Keep me posted.

Not sure why you guys think a T25 is small. It will make more power than our internals can handle.
because it is small. granted for our motor it may not be small, but a t25 is a small turbo. just because it can flow 16psi before losing efficiency doesn't mean that it is flowing a lot of air. each turbo at the same pressure will flow a different amount of air, so 16psi on a t25 is far less air than 16psi on a 16g, and a 16g is still a pretty small turbo. that is why people say it is a small turbo.

If you compare it to other turbos it is small. Just like a T60-1 would be small compared to a T88H. But we're talking about Mazdaspeeds, on a Mazdaspeed forum. Like I said, a T25 will make more power than our block can handle.
for any 2.0l motor, a t25 is small. just because we may have trouble handling the power it can produce doesn't change the size of the turbo. i'm not trying to say it is sized incorrectly for our application, because it is not, but the turbo is small.
our block will have no problem handling the power (it's iron), our rods might though.
this is an enthusiast site, and many people here like to perform modifications to their car, which address the weaknesses that are present in stock form. the turbo is small and should be replaced if you are looking for decent power on a daily driven car, but you are right for our car in stock or relatively stock form the turbo is sized just fine. many people like to go beyond stock though. the turbo is good to about the same levels as stock internals, but stock is no fun anyways, and with a proper fuel system the internals will most likely be able to hold more power than the t25 can produce.

When I say "the block", I mean everything in the short block.
The T25 should be the last part changed in the course of modifying. Intake, downpipe, exhaust, front mount, hard piping, engine management, injectors, boost controller, clutch, etc is far from "relatively stock" and CAN yield 260whp+. If you want more power than that it's time for new pistons & rods.
I'll have to disagree.
it's ok to disagree
i have my way that i would do things, and i know everyone will have a different way to go about things, none is necessarily right. but at 260whp, you're past the t25's peak efficiency, fine for every once in a while, but i wouldn't push it that much daily driven. but either way, i'm poor and am going to be completely stock until at a minimum next summer, so i'm not gonna worry about it

I don't agree proper tuning is everything. Piggybacks are more effective than you think.
If I end up getting a Mazdaspeed the first thing to come off is that tiny GT25 turbo. Why would anybody bother with any T series turbo unless they were trying to save money? Also why invest in bolt-ons when I would be re-engineering the whole exhaust from turbo to tip? Buy the bigger turbo, run it at low boost (stock ECU) and build the exhaust ONCE.
There are some custom hybrids using a T2 housing, based on the GT25 hotside. You can get a GT25 based hybrid that will push 400-440hp *(82m trim). GT25/40R is available direct from Garrett and maybe of it's dealer network.
The fuel and block are the least of my worries, its the tranny holding together after all the horror stories I have heard. Like I told somebody else -
Guess I'll have to keep a couple of spares around. Maybe import the Turbo-Diesel tranny from Japan. Because of the diesel's torque it should have no problem holding the power of a highly boosted FSDE.
The GT25 starts whezzing at 225h, you can force it to run high enough to get 250-250hp but it isn't going to like it.
I just about got it all figured out budget-wise anyway. Stock block should do 300hp without blowing up. Not forever, but until I can get some rods and pistons.
Mayne why does the 'speed have to be so HEAVY! (2840lbs)

during mazdaspeed development they had a t28 on it. too bad it didn't go into production. just some info for ppl.

Who did your front mount?
I was looking at using a good Spearco core or doing Air to Water with the intercooler mounted where the stock unit is and heat exchanger out in front. I need to get under the hood of one (might do that today) and see what's going on down there.
