lol Chris. Trust me I'm still torn on what I want. I'm waiting to here back from a friend about something. I just want to have something to keep up with my friends. All I need to do is go faster than 124mph in the 1/4..

 

I think it'd be prudent to obtain programming from the manufacturer of the ZC turbos (if it really is ZERO CLEARANCE) ...

Also, I didnt know that Softonic wrote software for the K16/24 hybrids ...

IMHO, I'd rather have the proper software for the turbos ... but I suppose that's just me.

TrojanMan ... how did Softronic become one of the options? What did you like about them?

 

I'm curious ... doesnt one need "special" software for the K16/24 hybrids because of the "quick spool" down low? I take it that more fuel would be required on the lower rpm band?

I suppose I need enlightment in this matter ...

 

To:Roadsterdoc...
What mileage are on your k16/24?What price you ask for?

 

Quick spool doesn't matter. It's just boost @ RPM and the X50 flash has the required maps.

Think abut it, the computer can compensate for exhaust, air filter, stronger wastegates, this is no different.

 

They have not been installed. Here is the FS ad:

Thanks,

Agreed. The fuel and ignition maps in K24 programming are plenty broad enough to cover the low rpm boost/hp/tq seen with the hybrids.

 

Saint Ari, the others are correct, I have installed ZC's and used the GIAC X50 program. Runs Great!

how much power are the k16/k24 capable of?

 

I have not dynoed the ZC's but would speculate 550+ at Stage4 level

 

Guys the K24 is the way to go. Even if you just bolt it in there is lots of room for upgrades down the road with larger compressors. Skip the K16/24 hybrid. It is a dead end road. Lag can be addressed with a nice free flowing exhaust. By combining the proper exhaust you will get boost response back to stock K16 levels. Check with Protomotive as he has really taken the K24 under his wing and got the most from it.

 

Your love for the K24 platform is well known and is justified, but I think you are a bit blinded by K24 juju. K24s have their limitations as well. Protomotive uses Garretts for folks ready to go beyong their performance, so one could also say that the K24 is a "dead end road." My point is that not everyone wants more than what the K16/24s offer.

I can think of a few quick reasons why someone would choose K16/24s over K24/18Gs:
maximum goal of 500awhp
budget of $4000-5000 (for turbos and tuning)
wanting to avoid any fuel modifications
wanting lagless response (perfect for autocrossing, etc)

K24/18G can take you up to 600awhp. The 550awhp setup will cost $8K for turbos and tuning. To reach 600awhp fuel pump and injectors are required (>$2K more). They are awesome no doubt but you can't say they are best for everyone.

 

I been thinking about the k16/24 or k24/18g for a while now too. I have pretty much come to a similar conclusion that the k16 housing is pretty much limiting you.

I just don't see how even a k24 w/ all the bolt on's can have SOOO much lag that its night a day difference vs. the k16/24.... plus after you've exhausted the stock k24's you can swap the interals to 18g for $1000 more and have the potential to hit 700 crank hp. As it was said before, the gt2 has k24's and i've never heard people complain that it has turbo lag, and it doesn't even have any bolt-ons.

Most of us arn't driving our cars on the track 50% of the time, or even 25% so the 2/10's of a second more lag and no potential vs. a little more lag but not having to fork out thousands later when more power is needed seems like a no brainer.

Also regarding the injectors and fuel pump, if you have the boost cut out at 1.2 bar, it wouldn't be running at its full potential, would you still need the fuel pump and injectors? (upgraded FPR is a given at this point)

Just a few thoughts running through my mind right now... i'm still listening to what people have to say but as a middle ground I think the k24/18g (or base k24) is the way to go... or with the gt28's.

 

Instantaneous low rpm response is just as important on the street as the track for most people. The K16 turbine will always have better low end response, where are the K24 turbine will always flow better at high rpms. It's not a question of which is better but of where are you willing to compromise.

You will need pump and injectors as you go beyond 550awhp. You can still go lean with the 1.2 bar throttle cut, and most tuners raise that anyway.

GT28s seem to be in between the K16/24 and K24/18G hybrids regarding spoolup and max power. They hit hard and fast, like the K16/24 but have much greater power potential. While the GT28s have quicker response, it looks as though the K24/18Gs flow better at 4000 rpm and above.
Again, it is about compromise. It helps to define what one wants before choosing a turbo. Is it a street driver? Highway pulls? Drag strip? Autocross? Track events? Top speed events? Each has different requirements and there is not one perfect turbo for all. And don't even try to ask who to use for tuning.

 

I feel my K24/18G spool just as quick or quicker than my previous K16/24 set-up that ran 11.5 @ 127 in the 1/4 mile. I did test drive a K24/18G without the fuel system and experienced more lag than the 16/24, but with the P700 package which includes the dual fuel pumps, injectors and corresponding MAF, it is a whole different ballgame. Power is instantaneous and strong. And it is a very reliable package. I logged 15,000 daily driver miles this year, plus a few track days without any problems. This is a very solid package with exceptional power and minimal lag. The 16/24 has more lag than a K16 stage 2. The P700 with k24/18G's and fuel has less lag than a k16/24. The power with the K24/18G, when combined with the fuel system is increased to such a level that the dual mass flywheel revs like a lighweight flywheel. It brings things to a whole different level...

Having had both levels, I tend to agree with K24madness...but they are both dead ends, however, the K24/18G brings you to the end of the stock internals, whereas the K16/24 brings you to an end where there is another option before you have to touch the stock internals, so it is slightly short of the full potential. From my experience - If you want serious power, go for the K24/18G. If you want a little more quickness, go for the K16/24.
