K03 Hybrid?

[AGU-TURBO]

Hi looking for some advice on a turbo upgrade, i have a 1.8t agu with a ko3 turbo im wanting to no whats needed to hybrid my k03 using k04 parts.

Thanks

First send your turbo to CR Turbos so they can hybrid it.... then you will need (as a minimum), S3 MAF housing (you will need your original MAF sensor though), silicone TIP, some kind of filter (jetex etc), S3/TT (225)/LCR injectors and a custom map...

Recommended upgrades are... FMIC, 2.5" or 3" downpipe, rods (if you expect to run a reasonable amount of boost as K03 hybrids are spiky on torque delivery)... you may also need an LCR fuel pump too depending how tired yours is as I have seen these conversions run lean due to a tired pump before on Ibizas...

im planing on building the turbo myself. jsut wanted to no what parts from the k04 get use. E.G hot side, cold side

Thanks for the reply

You cant just bolt the K04 parts onto your k03 turbo.

The original k03 housings are machined out so that they accept the larger k04 wheels. Presumably the centre housing is also machined out to take the larger k04 turbine/shaft/bearing assembly, or perhaps the K03 bearing is reamed to take the larger shaft instead. Its precision machining, not something you can slap together in your garage in an afternoon.

Specialised equipment and machining is involved... you can't just throw the turbo together from random parts... AFAIK, the core of a K04 is used and the K03 hotside and comp housings are machined to suit... CR normally upgrade the thrust bearings to 360 deg ones if you ask.... you also need an uprated actuator and sometimes the wastegate needs a little porting to prevent boost creep...

Right yeh that makes sence. so how much do they charge for this to be done. or is there a cheaper and better alternative.

many thanks

Did you really just bump an hour old post?!

You will need, turbo and a manifold, top metal boost pipe, inlet manifold and injectors, oil and coolant lines. Along with a silicone TIP, a suitable filter, potential for the 3"MAF. I may be missing a couple of bits there, but I think thats it.

And then you would have to have it mapped.

I would suggest you go to a KO3S because it is such an easier swap and will cost far less, it'll be good for 235/240BHP which is more than enough for a FWD road car.

lol im impatient. yeh i think you'r right it is looking like it will cost a lot more for not a huge difference

 

[badger5]

the hybrid will be some 40-50bhp more - is that not different enough for you?

 

[AGU-TURBO]

yes i would love 40-50 bhp more but for an extra 50bhp you are talking alot of money,

 

[badger5]

lol - power/performance costs

you think this is expensive?

Its all relative

 

[AGU-TURBO]

lol, yeh i no and ive been there in the past
