That much turbocharger on a high compression 3.6L doesn't calculate.
I know it's not ready for any serious boost. GT45 is daydream territory ie. after 8.5:1 and cams/head work. I'll probably see what a GT45 will look like under there though just to make clearance for worst case scenario and because I'm curious 
<400whp
Start looking at your net cylinder pressures when you're boosting it that much, the cylinders split.
Good to know; I'll gravitate towards under 400whp then. Is detonation to blame for that picture you posted of the split cylinder or solely peak cylinder pressures alone?
$75 for 1/2in SS flange
We have the oil lines and pump adapters in stock as well.
You may get lucky and gravity drain the turbo's oil, but we use an electric scavenge pump ($400) or an OEM gear pump driven off the cam like factory (requires modifying the cam).
Hoping a big drain + gravity will work at least initially. I have -10AN line + fittings and a 20mmX1.5 to -10AN adapter at work already. Should be good on the drain side as long as I got thread size right.
I will need that flange however + Garrett oil feed kit and 044pump and adapter. What's best way to get an order started since the flange isn't on off-the-shelf item?
The jump to 93-oct isn't that big a difference that you'll get a lot more performance potential.
e85, on the other hand, usually allows you to run a lot more timing, which is where your gains will happen.
80# injectors are alright for low boost on e85. If you end up reducing CR and running more boost, those are much too small.
Glad to hear, that's what I sized them for when I did my math. I wanted enough flow for E85 on low-ish boost to start with a little headroom to turn up a couple clicks or for boost overshoot before hard fuel-cut.
Those cores aren't efficient, BTDT.
Most everything off that website is Walmart quality. Someone put a lot of time, effort, and money into building a good-looking 993 Speedster -- don't cheapen the car by using junk components.
Use Garrett air:water IC cores, and as much high-efficiency aluminum radiator as you can fit on your car. It'll be more than enough for your current power level, and when you get bored and rebiuld the top-end with lower CR because you want more performance (or because you ran too much timing/boost and hurt the high CR engine), the same cooler will support over 550whp.
Yeah, ignore THAT particular one or website I linked as it was the first google result showing the shape I was thinking of. I'll try and fit a larger core though... I checked out the Garrett cores but they're just that... cores only. For at least initially, I wan't something pre-fabbed up that'll at least cut it for low boost and lay down the ground work of coolant lines, pumps, radiators, etc. Stock 993 decklid is a must currently. In-line in the return route of coolant for air:water could be an ice chest in the rear seat area as I have nothing going on there. This could be implemented when the small-ish core begins to need more cooling for higher boost sprints/limited occasions?
A standard 996T clutch will hold what you're doing and is completely streetable, just fine in stop-and-go traffic.
Also good to know, I'm guessing this is a pretty cost effective upgrade too being a OE part? Do I need a 996T flywheel too or can I keep my 964 dual mass and just grab a the pressure plate/disc kit?
