Default Cammed LS2 GTO adding ATI D1SC...do I have the right parts...?

Here are the specs for the car so far:

Keith McCord Custom Comp 224/224 .610/.601 112 LSA w/ 918 Springs
2000 degree coated SW LT's w/ no cats
Corsa Sport

I am going with a D1SC kit but I want to make sure I have everything lined up right. Here are the parts I am planning on going with:

D1SC Tuner Kit
Flow Matched Siemens 60# injectors with ev6 plug
20amp Kenne Bell BAP
255lph Fuel Pump (Walbro or Lingenfelter...don't know which is better)
Fluidampr Balancer


Is there anything I am forgetting? Is there a good place to buy this (everything but the ATI Kit) stuff online? Perhaps one or two places that I could get it all at once?

Thanks for the help guys.

The cam is not too SC friendly, but will work. I think you should be good in the fuel department.

Yeah, I talked to the tuner and he said that the cam would be fine with the D1SC. In the future I will probably switch to a more FI-friendly cam but at this point, I think it will be fine.

Is there anything I am not listing that I need for this kit besides the fuel stuff and the balancer?

That is really a loaded question. It really depeneds on what you want to do with it and possible future plans. With what you listed, you should be able to run the D1 safely on the motor.

Also pin the crank while the kit is being installed. It will help save you from headaches later on.

You're right. I meant on the motor as it sits. I just don't want to go to do the install and not have everything I need.

Why would you want a D1SC on a 10.9:1 motor.
If you're set on that bigger SC, then consider reducing your compression via a set of 6.0 heads 72cc, then hello over 10psi.

Also your springs will need be changed to duals, that can be had on the heads.

I'm probably not going to do the heads just yet. Why would I need new valvesprings? These are the ones recommended by the tuner who had the cam custom ground.

Did you tell him they would have to deal with FI when the cam was ground?

If you get valve float with the D1 on there you will have a bad day.

with FI there is that much added pressure to the face of the valve... hence why they say 15 or 20 # of boost....

Do I need the fuel rail adaptors and extensions if I get the injectors with teh ev6 (USCAR) plug on them already?

I am going to switch out the valvesprings to Patriot Duals and going with hardened pushrods. I just can't do the heads right now.

Would roller rockers do anything for me?
