interesting from CRT though that they buy in the K04 cartridges complete from the states (factory spec built) and dont touch them....yet they put a 360 thrust bearing in them somehow.....
When my turbo was sent back to Turbo Dynamics when I was having all those issues with the JBS manifold I spent some time speaking to them as well as Mark at CRT to clear up a few common misconceptions as there seems to be a lot of false information flying around unfortunately
Not normal levels but remapped power levels, only hopefully a lot more reliable with greater scope for improvement.
My thoughts on the matter are simply that Revo stage 1 (as a pure example of a remap) will get 200bhp~ from a stock 156bhp K03-045 powered lump with no extras, the only downsides obviously being the turbos own inefficiency to hold boost and the amount of boost it can handle. I was thinking that with a "hybrid style K03" I could bolt it on, get it the ECU mapped and enjoy the 200bhp~ without having to worry serious turbo degradation due to the increased work load (as opposed to remapping a stock K03).
Admittedly, the extra components would make the deal a whole lot sweeter but I'm trying to figure out whether they are ACTUALLY required or just preferred.
Correct me if I'm wrong, but surely 200bhp @15psi~ is 200bhp @15psi~ regardless of the turbo is providing it? From what I've seen in this post, the only physical requirement is possibly a larger TIP and fingers crossed the forge will stretch

Wrong..
a GT2879R will make alot more power than a k03x at 15psi. Juat an exaple.
quick update mark rung me from C R turbos today. My housing is slightly cracked. He said not so bad defo need replacing but not good enough not to mention anything. He said personal preferance. So I opted to change the housing for a secound hand one that they will supply for an extra 100 quid. Hope clears that one up

sorry but none of that makes sense
why would you bother having a k03 made into a hybrid to only clip the power at 200bhp
why not just stick with a normal mapped k03....
the extra components are only needed if you are going for a TRUE hybrid setup and want the most out of it
obviously if you have spent the time effort and money getting the k03 hybridized, then I would think you would spend out on the mani etc
and NO, 200bhp at 15psi is not just 200bhp....its WHERE it is holding that peak power
a k03 could make 200bhp at 15psi....but peak at say 4000rpm.....as where a k03s could make 200bhp at 15psi, but peak power would be at 5000rpm and so on with the hybrid k03
its not ALL about figures, which is why people upgrade to the k03s or hybrid as its where the peak power is made, not the total figure..you want the turbo to hold onto as much power as possible...all be it the same power for example, but allowing it to rev more freely while still flowing the same amount, shifting peak power and effectively allowing the car go faster
understand?

Well put, thats what i was trying to get at earlier. No point shelling out for a hybrid unit to de tune it and run it at 200bhp, kind of defeats the object imo. Best off just nuilding it al up piece by piece, gettting it bolted on, then mapping it at the end.
Jamie, you've basically just answered my question entirely but somewhat missed my concerns over loosing reliability by mapping a stock K03.
I fully appreciate that a stock K03 will run 200bhp. I've constantly approximated to 200bhp as to try and avoid focusing on a particular maximum power output but more the feasibility of the idea. Obviously more power the better and if a hybrid turbo being directly swapped for the K03 will give more power then bring it on
Tbh, it's not even about the effort or money as neither are anything serious, I just don't wish to go 'all out' if I don't need to.
Understand
Thanks for all your comments though, I've a much better idea now and think I'm going to get on and do it.

I think I am still a little confused
you are not maxing out a k03 by turning it into a hybrid, its not as if a reputable mapper/tuner will MAX out the turbo to its absolute limit and run silly boost, till it blows
a hybrid is fitted with such aspects like uprated oil seals and a 360 degree thrust bearing, allowing for much stronger and sustained boost without maxxing it, or risking it detonating
hybridizing is not just about power, its about strengthening an orignal k03 unit as well as improving its performance to give realiability but a very nice increase in power
you will get bored with 200, and if you are shelling out the money, stick a hybrid on
has anyone had a k03 turned into a a hybrid yet by CRT? as they will have to change the actuator and would they charge extra? as k03s they use the existing one unless you ask to upgrade.

is the actuator different then on the k03 and k03s?
thought it was only the turbine that was different...learn summit new everyday!
the k03 actuator has 2 vac lines where as k03s have 1. as when mine was hybrid'd they kept the same actuator as it can cope..
we will find out when cupra jobe's come back

lol Jamie you do understand, you've just confirmed what I wrote exactly!
Running a hybrid means I can run 200+ without a care in the world, well until, like you rightly say, I get bored and start installing other bits
Does it run on the stock oil feed or does it need the larger one as the K04 does?

so it depends where you are having the turbo done, Robbie knows how the 2 differ as i believe you have been out in a CRT one and a JBS04
Whats that supposed to mean
Share your views.
I used my old k03 for my hybrid and had the actuator changed for an uprated garret style one ~14-15psi.
From speaking to bill the k03s actuator (5-6psi) will not cope with this turbo, i belive that JB had his hybrid sent back the first time as it was supplied with a 5-6psi actuator, meaning that the actuator would blow open under the power.
