That's to much compression unless you are going to keep the boost at 8psi or less. Make sure you have a good 'tune' shop to burn a chip for it. (that way your WOT timing will be in check)

As far as injectors and MAF, it depends if you are running an FMU or not. If you are running an FMU then you could probably run a 30-36 # injector set. If not, then use a set of 42's with a boost a pump.

Since you are on a draw through setup, I would say either a Pro-m 80 or 87 would suit you fine.

Thanks for the post. I plan to run only 6 psi boost. I want to make most of the power on the motor. The NOVI 1000 is small, the paperwork says good to 500 HP, it might just be a restriction for the build I am doing. I have a performance engine builder doing the machine work he is setting up the clearances and such considering my combination. I am still learning about some of the things like FMU but I think the car has one already with in tank 190 lph pump and 24# injectors. Tell me if I am wrong about the FMU, is it a unti that looks like a fuel regulator and it has a seperate fuel line that goes to the fuel rail?

Update.
I decided to drop the compression ratio to 9.0/1.
I am purchasing 42# injectors and matching MAF meter.
Everything should be ready to pick up from Machine shop on Friday.
Guess I will start putting it together this weekend.

For what it's worth, I spend some time over at www.honda-tech.com and there's a number of guys running well over 10:1 compression with moderate pressure turbos (6-9 psi). They are achieveing incredible torque curves for small 4-cylinder motors and are disproving the idea that you "can't" have high compression and forced induction. It seems to be down to the strength of the components used and the tuning. Water injection also doesn't hurt.
