Your only limitation will be the fuel you run.

Compression isn't high at all. But, the other limitation will be that 18g.. Go BIG or GO HOME!!

you're planning to tune this setup right ?
your tuner can work with that compression ratio.

a built block and only a 18g ?
what is your power goal ?

The compression shouldn't be a problem with a good tune. But the turbo I would upgrade.
