If you want to race it in a heads up class what size turbo would you have to use? Travis picked 2- 78mm turbos for my build. One of the classes I want to run in will require them to be reduced to 67mm. Just something to keep in mind.

Which was the main reason I went with FI. If I have to make changes from one track to another I wanted to do it with my laptop. Im not a carb expert so I felt a little more comfortable being able to rely on making changes with the laptop.

I used twin 160lb injectors, but Im running meth not gas. FAST has some info on how to calculate how big a injector you will need using pump gas. I would look at the 225lb atomizer injectors if your planning on running pump gas. I've read good things about the ability to tune them.

My twin 160's were tough getting enough fuel out of them at a idle. Im still getting some raw fuel but its the best I can do with a FAST classic. If you look at the BS3 controller I think you can control when the second set of injectors comes in. You have to first decide what fuel and max HP you want to make.

I was told to use Ti intake valves and Super Alloy exhaust valves.

Think about turbo placement as well. I had to raise my motor 1" to get the headers to clear with a std edlebrock head. I used 1.750" header tubes. When I buy a new head I'll plan on using one that has the convertible head option. That would have made my life much better during the header fab.
If you place them lower than the oil pan plan on a oil reclaim pump as well.

See it doesnt take long for the money to start adding up. I spent $1400 on the aluminum tubing for the cold side, carbon steel headers and 3.5" stainless exhaust tubing. I built all of it my self except the exhaust flanges.

I would also recommend using a forward facing TB. My dominator hat is roughly 6" above the fender line. This might require a sheet metal intake but I think it would be worth it in the long run.
