is there any other turbo charged P11 running around? i've seen a couple with turbo kits, but havent see anyone dropping the DET in it yet...just curious.

Nah haven't seen any of them in NZ but I am curious why the hell bother with the expense to fit a KIT?? It surely must be cheaper and more reliable to do what you have done G22det.
Everything is stronger and configured already in the SR20DET for a turbo, you would have to get piping and I'm assuming a new/modified ECU to run it (You can't run the same boost either). What waste of money. In Nz people have added turb's and can't generally exceed 7psi boost.

I've seen "kit" turbo SR20 engines (stock bottom end) run 350+ front wheel hp on a dynometer (20 psi, pump gasoline). "Kits" can include much larger and more powerful T3-04E turbos than the stock DET engine has. Yes, you can add the T3-04E to a DET engine, but then you will need a new manifold and piping too, just like a "kit" SR20 turbo engine has.
This has been debated lots of times on the SE-R mailing list, you can read up on it at SR20DE.net

Those 350+hp stock bottem end SR20's are also running water injection too, right?

Yes, water injection is achieved by using the windscreen water resevoir!
One of the better writeups on a "kit" turbo SR20DE is at

Also a good read if you're interested in SR20 turbos in general.

Oh my god I think I know that article by heart! :) Much of my insperation for buying an SR20DE car came from that article alone.
