Which turbo?

I'm having a hard time deciding which turbo to get. This car is going to be a daily driver, occassional auto cross, occassional drag race. I want to make as much power asa possible with out creating lots of lag that makes the car suck at autocross. So far the turbos I'm considering are.
1) Small 16G
2) Big 16G
3) Frankenstien junior 17C
4) Frankenstien junior 19C
Of these, which one would be the best for what I want? If you have any experience with any of these turbos please let me know what you think of them, or if you have any other sugestions please state them.
Thanx.

Id go with the Big 16g. It is the most common so the most parts and general knowledge will be around. Its pulls plently hard too with almost no lag increase.

So the big 16g wont have too much lag for autocross? I had almost talked myself into to getting the small 16g and then if it wasn't fast enough at the drag strip adding some NOS, now I need to think about it some more. Regardless of which turbo I get should I get it clipped? From what I've read clipping greatly increases performance at the top of the power band, but adds some lag. Just how much lag does it add? Is it more than I'd want for autocrossing? Thanks for the help.

A big 16g would be fine for autocross. It would probably be a better choice to pay the extra 100 or so dollars for the big 16g than having to install a N2O setup. About clipping I would say go for it. It will make the turbo pull harder at the top end and shouldnt affect spoolup that much. Your looking at losing just a couple 100 rpms. Either way you go I would definatly get it ported and maybe a 34 mm wastegate mod or external dump O2 if you get boost creep but that mostly depends on how open your exhaust is. Enjoy your new power :)

Thanks, I was definatly going to get it ported. If its only a couple hundred extra RPM's of lag, I think I can live with that. I'll get a clipped and ported big 16g.
