That much turbocharger on a high compression 3.6L doesn't calculate.

Is 500hp/450tq (so ~425WHP) possible on stock rotating assembly? I don't think detonation will be my limiting factor with E85. Will keep the stock redline/revlimit of 6500/7000 due to rods bolts and valvetrain.

<400whp
Start looking at your net cylinder pressures when you're boosting it that much, the cylinders split.

$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).

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.

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.

Something that's easier to modulate and will hold up longevity wise (so maybe kevlar faced?) but that clamps down when I drop the hammer. Does my car being a Carrera 4 vs a C2 G50 make things any different? |
A standard 996T clutch will hold what you're doing and is completely streetable, just fine in stop-and-go traffic.
