6766 Build
So I got my hands on Evo shell that came with a 6766 build and I’m currently building it but I don’t want a super drag aggressive car , I want a chill car that can be drivable and give sauce . It’s on 6766 , GscS2s , 2150cc, dual walbro 450s , built head , 2.3L
Is it all based on how much boost I push? Or would it be better to drop the injector size and take a fuel pump, also I’m looking at switching my intercooler + intake mani + throttle body , is there any recommendations for a more “ stockish “ feel when just cruising
edit * thank you guys for the replies I appreciate it

The 6766, although very capable peak power/trap speed wise, is not going to be a fun street car for the most part even on a 2.3. Your cams/injectors/fuel pumps are fine, consider stepping down in turbo size. 6262/6266 or even a 6466 will offer much better response thus equaling a more fun sauce giving ride

A reputable tuner will be your best asset for driveabilty and keeping it together. I also agree on going to a smaller turbo. A gen 1 or 2 3582R works well and can make 700whp or so all in. Spools up well by 4200 with a small housing. Thats about as far as you want to safely take the 100mm crank.
Could also consider a next gen 6266 if you want to make more.
