What did I buy?
So I just picked up a S4 turbo from a website. they advertised it as stock, but it is clearly not completely stock. I have some questions on what it is that I ended up with. I posted this on the first generation forums, but I suppose the 2nd gen forums would probably have more info.
Here is the link, so I don't have to post the whole thing again.

It's defintely a hybrid S5 turbo. The 0.60 A/R housing looks to have a small inlet (~2.5"), so it almost looks stock, but the compressor, compressor housing, backplate and WG actuator have all been swapped. Stock turbos have "HT-18-2S" on the compressor housing.
For the injectors, 199500-0830 is not a stock PN, so they're aftermarket Denso. The blue color makes me think they might be Greddy/Denso 720cc injectors. Mine are light blue on top like these: http://www.frsport.com/GReddy-135000...ACH_p_791.html

Sorry for neglecting this post for a while, I have been on the road for work a bunch and haven't really progressed at all with this project. I have been collecting parts though! I have gaskets to put the intake and exhaust back on the engine, I have a fuel pump, intercooler, and now an upgraded radiator on order.
The engine didn't come with the ignition modules or coils, or an MAF sensor. I'm looking at rounding those things up now, but I am kinda stuck on the ignition. Stock replacements are seriously expensive, and after searching the forums it seems like that is really the best way to go. Anyone know where these can be found for pretty cheap?
I got the engine from this website.http://www.jdmenginedepot.com/jdm_engines/Mazda/
Thanks for the info on the clutch/flywheel, injectors, and turbo. Every little bit helps when trying to piece together this puzzle.
