Hybrid turbo build

[Ian Simmonds]

I've got here an old Wr Ur quattro Turbo (KKK26K) and a later S2 KKK24K - can they be refurbished into a hydrid with 26 compressor, 24 exhaust and water cooled. And if so, does anyone recommend a turbo builder/overhauler?

Thanks in advance

There's no point doing this. K24 compressor is more efficient and larger than K26 (ur-quattro). K24 compressor, and K26 hot side (for less back pressure) - more like it.

One day I will try this (have few K26's and four or five k24's sitting in garage...).

I can have a word with Grant from AET, if you want?

Oh dear, have I mis-understood turbo's Sorry.

I'll rephrase the question, 2 Turbo's, KKK26K and a KKK24K... Can a hybrid be made of the two to make better power... And if so, what's the format?

Thanks Bry, once I know what I'm up to, It'd be appreciated!

Not so fast my friend . Doing anything from audi petrol K24 and K26 - requires machining. Audi K24 petrol - IMHO uses 6mm nut, and K26 - 7mm.

So you have three ways. First - you need to find apropriate compressor wheel to fit cold side, or find apropriate hot side. Next - you can precisely machine compressor wheel or axle. Third - the simpliest, (and the hardest for me) - just buy proper turbocharger. It's not so expensive. Uu paid around 2k Lt for K26/K27 fast spool hybrid .

Ping ... Thank you Sau.... Will look for an RS2 or GT28...

I like machining. Do not like spending k Lt. If I had K24 on my hand... Then quicker thinking/motivation is possible.

@BRY
Can you please ask AET if an allmost new (some kilometers)large frame turbo needs rebalansing if i change the compressor wheel for a factory new balanced one. i have asked over here and they said that with large frame , holset hx40 turbos like, with no damage, they dont need anything because all the big turbos are ballanced separately. Turbine impeller with axle and compressor impeller separately.

thanks
