780cc / 880cc (found in previous thread)

I went with 780's. I would have got 880's but the race gas I use is only 100 octane so I'll probably run 26psi max.

Depends on the boost level. On a car with a flash and pump gas 680's are enough. With a car making big power on bigger boost levels you will need an 880.

Would 680's be enough for alky injection/flash on pump gas at 25psi?

Ok, this may be a dumb question but im new to the whole turbo thing coming from owning a honda...but my question is, what kind of difference would this upgrade make if i just have the regular evo8 turbo right now with a mail-in dyno flash and a k&n drop in? I mean would it be a massive difference switching the turbos out like that?

You have a lot more upgrades to do before you switch out turbo's like that. Check out Buschur's site. They have an upgrade sequence before you swap your turbo. I believe Dave will tell you he recommends getting to BR Stage 4 first and then doing a turbo swap. That way you ensure you have enough fuel/exhaust flow to even power the turbo.

The 680's are plenty if you have alky injection too.

The 20G going on a car without Stage 4 is silly.
