turbo upgrade

[archangel_7]

hey guys,

I'm thinking maybe sometime in the future to upgrate to a k03/k04 Turbo... I found this turbo on a site http://www.gpopshop.com/kkkturbos.html

does anyone also know how much more power you would get out of one of these?

It SAYS 1.8T engine, not sure if this would suit a polo gti..

Just out of interest do you have other upgrades to support the bigger turbo?

Just wondering as I would go for a bigger intercooler or charge cooler before a turbo.

You also need a different tune, APR will give it to you for $700 unless you buy the part from them from memory.

Also, you'll need better cooling and induction for a bigger turbo I would have though.

That to me looks like a k03s based on the fact it says k03/k04 so just want to check that

You can get suprising performance results from upgrading your intercooler.

I would do this before I upgraded the Turbo, that should be last on the list.

Its pretty much the same turbo but your replacing the front end of the turbo.. you can run it at a higher boost. you can use the same down pipe, its a direct bolt on, except to get more power an exhaust is suggested...

here is some very intersting info i came across....hmmm maybe its not really worth the swap i guess...

That turbo wont fit the polo unless you run an S3 manifold. The compressed air outlet is placed differently to the K04-001 that is used on the polos.

Thats an A4/Passat turbo , its completely different .
Your running a KO3s , not worth changing to ko4 unless your searching for every last hp !

Hangon im confused, What turbo does the polo run? i thought it was a k03

[Bug_racer]

KKK KO3s ..................

[archangel_7]

From what I understand is the K03s and K04 use same size compressor wheel? K03s has slightly smaller turbine wheel/housing (not sure which one, if not both) than the K04...SO IM ASSUMING the K03/K04 turbo will be a different attachment on the turbine wheel housing assembly? Isn’t that what a k03/k04turbo is? Your original turbo with the different assembly?

Yeh your probably right there mate, I realised now that it wouldn’t be worth it considering its only a 5mm difference on the turbine wheel, which would threrefore mean more turbo lag I would be guessing.

The one posted in the OP has a different housing to the one that is used in the polos.
