My mechanical preturbo water injection

I'm running an HKS twin power with stock coils, 10 mm wires, and greddy race plugs (rebadged ngk 7420's) heat range 10.

If I was redoing the ignition from stock I would go with a Crane Hi6 and LX92 on each leading plug, and stock coils for the trailing. The twin power does work very well for my needs so I won't be changing it out anytime soon.

I haven't been on a dyno yet but I expect over 500 RWHP. If I was to guess I would say 530 or so, maybe more. I also have a very large street port so that will play a big roll in what you can expect. There's another guy on ausrotary with a similar setup to yours, gt45 on a 13 bt extended port, he made 530 on a street tune and then made 550 after dyno tuning, this was at 25psi. He's going back soon and trying to break 600 with 30 psi.
