There is a GT28 Eliminator Kit that a lot of companies make for Audi's. In fact there is a kit for sale in the classifieds section right now.

I think it's a good product since hot side keep the same wheel size and intake side uses
a bigger wheel K04 or better K16. It can produce a good 400 HP with some fueling mods
+ you dont need to change your inlet pipes --- $
Do some reeding and happy tuning

 

Does anyone have any links to information reguarding building a hybrid myself? Is a ko3/16 a ko3 hotside with a k16 cold side and turbine?

 

ko3 hybrids always utilize theko3 cold side. The hot side is what changes, which could be ko4 or k16

 

Oh, i see. What about the turbines, what is that setup like?

 

I have the k03/k16 buehn hybrids right now. Make good power and come on faster than the k04's good foraround 450 crank hp. Little fueling and you have a fast car for alot less. I'm definately looking at bigger turbo options and probably will have a VAG gt25 setup mid-summer.

 

What do your hybrids consist of? I have some spare time so I thought it would be a nice project to build some ko3/16s. What parts do I need besides a ko3 cold side, and a k16 hot side?

 

When you put in your gt25's are you going to sell your k03/k16 hybrids? If say I may be interested. Also are you hoping to put in the gt25s through the front of the car like you did before with the k03's?

 

I've got a second project that I'm swapping the hybrids into so probably not selling unless I got the right offer. As for putting them through the front, it all depends on the size of the gt25s I still don't have measurements of the housings or the manifolds needed. If they look like they will fit I'll try it, if not I'll just pull the motor. I rented a shop now so I have a place to put a lift in, which always makes life easier.

As far as building your own hybrids, the buehn units have billet housings, the k16 wheel goes in the cold side and the k03 housing is machined to make itfit, not changing out the whole housing. So you'd need a cnc machine which might be a little expensive unless you have a shop nearby.
