Upgraded cooling system componentsYou can make ~540RWHP on pumpfuel with this setup and ~650RWHP on racefuel. Reliability? This is an interesting topic not spoken of much around here yet. Fact is, at these power levels you are going to be taxing the non-upgraded components within the powertrain - namely engine bearings and tranny internals. FWIW, I recently replaced my rod bearings at 17K miles just for the sake of doing so given the power levels I'm running at as well as due to the major modifications I made to my crankshaft. The bearings were showing signs of wear - some showing into the copper substrate a bit. I'm sure this statement will come with its share of contest, but I would recommend that people making these elevated power/torque outputs should budget a rod bearing replacement about every 15K miles or so. I know I will be digging back into my engine around the 30K mark to do it over again. As for drivability, although the turbos I mentioned above are a decent step up in size from stock, with all the other mods listed, you will retain a large degree of intown drivability and response and still be able to turn her up to 11 at the track with impressive results. 750RWHP is really a very difficult amount of power to try and put to the ground. You will also be looking at using even larger turbos to achieve this, which is going to take away an appreciable amount of in-town fun as spoolup response is going to suffer. I personally wouldn't shoot for building a setup with that peak power potential if I also expect to drive it around town. Even at 18psi producing ~540RWHP on pumpfuel, it is a bit much - can't really plant the wheels until 3rd so there's a bit of "pedaling" in 1st and 2nd.... manageable though..
