I'm new to all this stuff, but I've done a little bit of research, and if I'm not wrong, the Hahn Stage II setup comes with a 16g turbo, which flows about 475 CFM. I believe that puts it's maximum output to around 310 horsepower right? I'm eventually looking to grab myself a setup that puts around 350 to the ground. I know it's a bit crazy for somebody as new as me to be shooting for something that high, but it's definitely going to be over a very large time span.
Assuming a 5-10% drivetrain loss, that's roughly 390 at the crank, what kind of turbos are able to put this type of power down? Thanks.
The hahn 20g can hold right around there if not more, the only problem with going with a turbo that large is the internals of the car will more than likely need to be modified also. also it take longer to spool a turbo that size if you dont have the supporting mods. but if the engine is built correctly the 20g can easily spool you up to your 300+ mark.

Thanks, I'm aware of the need to build the engine a little bit. I was going to go with this, at the very LEAST;
Eagle Rods
Wiseco Forged Pistons 8.9:1 Comp. with a .020 overbore
Patriot Stage II Heads with Cams
SPEC Clutch (not sure what stage would suit best, any input)
Like I said, I'm very new to all this stuff, so if I'm missing anything necessary or have anything that's amazingly wrong, please let me know. Thanks.
Another question if I may. I was thinking of buying the turbo kit first, and keeping it at low boost, and then whenever I upgrade the weakest link, turn it up a little bit until I eventually reach my goal. Is that doable, or am I asking for trouble? Thanks.
A T3/TO4E 50 or 57 trim with a .63 a/r turbine are a couple good choices for your power needs and should be pretty responsive. Or if you want to spend a the cash to buy the best of the best you could step up to a GT3071R or a GT3076R.

Thanks for the input.
Also, does my minimum parts list looks okay to you, or is there anything that needs changing, or anything I'm missing?
As well, a turbo before the reinforcement is okay, as long as I'm keeping the boost low, right?
Thanks again.
Alright, thanks for the help.
with your build list, the rods, pistons, and such will work perfect, and as for the clutch here are a couple ideas with spec.
They make a stage 3 kit that you can get in a 4 or 6 puck design, the fewer pucks means it will grab better, but it is also a pain to drive on the streets and in traffic. they do make a stage 3 that is a solid disc that will work up to 400+tq i believe that is a lot easier to use on the streets, but still stiff. my suggestion is dont change the clutch till it needs to be changed.
a t3/t4 is a very good set-up and is capable of making a lot of power. if im not mistaken that is what Skilz runs in his 13 sec. cavi. and just remember that the bigger turbo you put in, the longer it will take to spool. but there are also ways to get rid of SOME turbo-lag. and if you really want to get nuts with it your could throw in a GT35R, GT37R, or even a GT40R (like Adam Hahn). and all the GT series are a dual ball bearing so they react nicely and dont loose much spool between shifts.
I am working on my set-up now. But mine is fully custom. Im taking a turbo from the SRT-4 i am building and putting it in my car. It is small enough to spool very quickly and doesnt require much to spool it. It is also very well suited for low boost. I will be posting progress of it when i get a little further into it.

Wow, that was a very helpful post, thank you. Also, I was planning on keeping the stock clutch until it needed to be replaced anyways, but wanted to know which one I should get when I finally replaced it, and I think you helped me make my decision. In light of the information you've provided, I'll probably end up going with a stage 3 solid disc, thanks.
Also, thank you for the reminder of the turbo spool time, I am aware of spool time issues with larger turbos, but I still appreciate that you included that information. This would be a street driven car, and it would probably be better for it not to reach full boost until the higher RPM ranges anyways, to keep daily driving easier. Thanks again.
Lastly, thank you for reassuring me that my part choices weren't totally stupid, as I said, I'm still learning and I had a pretty good idea, but wasn't completely sure. Thanks again.
No problem buddy, and one more thing. With any turbo you can still decide how much boost you want, and you can also decide when it will spool if you put an external wastegate on. just have fun with it, and ill let ya know if i ever get mine finished. first i have to finish the SRT then its on to my car.

Nice, you should do a write up with pictures of the process if you're not too lazy to ;P Also, thanks for that info again, I'd be nice for it to spool around 2.5-3k RPMs, so daily driving wouldn't be so hard, but if I decide to have a little fun, it goes.
Thanks again.
