⟰⟰⟰⟰⟰If you are going to go SC, the DOB kit is really solid, especially with max effort intercooler, lines and pumps. I did this last year and while it hasn't gone smoothly, none of this is really the fault of the DOB kit. When you make a change like that, there's a lot of secondary systems that need to get beefed up to support it and you are adding a bunch of weight to the front of the car. You also changing the handling characteristics of the car pretty substantially due to the way the power comes on. I'm still running slightly slower lap times despite the additional power because I'm fighting for traction in places where I could go flat out before and I have to change gears more often.
SC cars for drag racing or cruising on the street can live with some of the short cuts most people take with adding a SC to these cars because they don't run full tilt for very long. Since upgrading, I've had to upgrade my alternator, radiator, add an oil cooler, replace my fuel lines, and add hood louvers. I had to rewire my fuel pump, alternator and radiator fan to higher gauges to support more amps. It's also likely that clutch and transmission are not long for this setup - they are rated for 300hp and are probably seeing closer to 450.
Jason has a good overview of the various KB kits (biased of course) but it does discuss some of the benefits and drawbacks of the kit. The big concern I'd have with the stage 2 kit is the IC and pump but both have better replacements that just bolt on.
Exactly!
