K24s or Stage II ZC or what???
Howdy. I'm having a hard time making up my mind with what turbos to get. I have a UMW flash, UMW LWFW, k16s and a Tubi muffler. I would like to make as much power under the curve as possible with the least amount of lag. After talking with Kevin at UMW I was set on Stage 2 ZC(~540awhp and ~570 awhp with the race file), but the price is just too much for me($6500 I think). Just hoping ya'll can help with some suggestions.
Should I get a set of K24's and send them into UMW for the wastegates and upgrade tuning for $700(UMW price)? What power would this yield?
If I buy a pair of K16/24's can anyone tell me if UMW K24 programming will work?
I could add a 5bar FPR and upgraded fuel pump to the mix as well.
Thanks for any and all suggestions.

i am biased...but aren't these questions for kevin???
zc is the best solution for no lag IMHO. id save up and do it right the first time or you will spend more chasing your tale. he has packages for a reason...they work best in matched setups vers piece mealing something together trying to save money, trust me...doing it this way, in the end you won't.

Please correct me if I’m wrong, but I understand the UMW K16 Hybrids flow a lot more air than the K24’s. I recently spoke to an Australian guy who upgraded to Kevin’s Stage 2 ZC package. Apparently the package is absolutely awesome !! I hope to have an opportunity to ride in the car before Christmas. At this stage it is highly likely I will take a similar path…..UMW S2 ZC. I also welcome any comments re similar HP for the same $$$ spend.

Not even close. The K24/18g will outflow the K16/24 in everyway.
To compair a K24 to a K16/24 is knowing that you decreased the size of the hot side (k16/24) and sacraficed flow for better boost response. Using a K24 based turbo will always give you better exhaust side flow over any(ZC or not)K16 based turbo.
If the main concern is boost response with less regard to overall power then K16 based turbo is the answer. If max power with still great boost response is desired then the K24 based turbo is the answer.

My lil 2ZC made 540 at the wheels on pump and 580 on race (I wish I had more race fuel!).

Try not to get hung up on the numbers. There are enough cars around with each setup so you should be able to get seat time in each.

Hmmm.... Kevins Stage 2 ZC turbo's seem to flow really good uptop and spool up silly and low (I get .2 bar at about 1600 rpm with moderate application of the throttle). I'm not sure Kevins' 2ZC setup is a 16/24, it may be, but one has to remember that the compressor side has also been Zero Clearance treatment which changes it's efficeincy significantly.

I still stand by my statement. If you were willing to sacrafice some spoolup you will get more power with the K24 based turbo.
Zero clearance on the compressor side reduces compressor temps slightly. Depending on the intercoolers used that may or may not affect intake temps much.
The flow capibilities of the compressor (K24 in this case) are not changed by the zero clearance process. FWIW the Kevins stage3 wheel (super60T3) is a better choice for the K16 based turbo if you feel the need for more and still want to stay with K16's.
You should try to get some seat time in a K24/18G car with proper tuning and exhaust. Its a whole new world.

Another way to put it is with the K16/24 the car feels sweet, nice and quick - an enhanced version of the stock feel. With the 24/18G's the car feels nasty fast. It depends what you want. Personally, I would never go back to K16/24's after experiencing the added power and quick response a K24/18G provides. These turbos are a blast!

Kevin's Stage 1 is a K16/24 based turbo. I am not sure what the Stage 2 is. I just checked his webpage.

Agreed - it is like gaining the increase from K16's to K16/24's, one more time and substantially changes the acceleration dynamics of the car. With the K16/24's, I felt like I had a pretty fast car. With the 24/18G's I know, I have a pretty fast car.

From your experience, how streetable is the K24/18g setup compared to stock or K16/24?
