Very good work. Thos Busa's are amazing. I want to get one, but I'm sure my life would be shortened greatly.

What turbo kit are you running on the bike?

They make nice plenum stock that is very strong. How thick are the velocity stacks you are using? I was going to use velocity stacks made for weber carbs, but they are too thin...

I have two sets of velocity stacks for my ...

I have a set of green tops right now and want to upgrade to a set of 1000cc precision injectors. Are they physically the same size?

Yeah, thats what I was trying to link to. People with supras are idling 1600cc injectors at 1100 rpm. 13:1 A/F ratio.

"My car has 1600cc's, idles at 1100rpm, 13.0 a/f. No injector driver and I have enough fuel with three Walbro's and the 1600's for over 1300rwhp with ease.
