swap ko3 for ko3s

[dam088888]

Hi all got a 1.8t agu with stage one map on a ko3 if I do a swap for a ko3s will I see much more power or torque difference

[Dave_IOW]

Yes in a word.

Boost comes in quicker, stronger, longer without remapping again.

I believe you should have it mapped for the ko3s though as everything will be thrown to pot where you got different turbo than mapped with.

This is the exact stage im at right now btw, so i do know lol.

What you may find is that once you come on full boost, the MAF reading gets too high and knocks the boost back to save engine. Mine peaks 21ish psi, hits the cut off point and drops to 10psi, annoying when racing (on airstrip )..

Obviously a map made for the ko3s would sort this.

So do you recomend this or not cos I have one just no t sure wether to install or not

when i upgraded mine i saw a rough 30bhp gain and 40lb/ft torque increase.

Boost on a Stage 2 is around 22psi peak and holds 18 psi, stage 1 is around 16psi peak and hold at 12ish psi. but this can depend on the car as some turbo's are in better condition to others, along with the actuator. I found that i was maxing the MAF out and needed to go bigger maf to get more power after the upgrade.

And yes it is deffo worth upgrading from a K03 to K03s, it will put a smile on your face and make the car feel lods better. To get the most from it make sure you have all the supporting mods like, Larger TIP, Forge 007p, Cat back exhaust, Enlarged downpipe with sports cat or de-cat ( This makes a difference as it lets the turbo spool up quicker. Then get the turbo fitted and mapped. optional mod which would help produce more power is FMIC

Yeah I got forge 007p so is it a straight swap take off ko3 bolt on ko3s

Yeah stick it on now and save up to get it mapped..

Jamie16v had a stage 1 map, 190hp and put his ko3s on, and when he went to get his up to stage2, his 'before' power run was 212hp

You will need some new bolts and gaskets around 50quid..

[dam088888]

Why can't I use bolts for ko3 and where would I get gaskets from gsf ?

[Dave_IOW]

Got mine from VW, think its due to the rediculous heat turbos produce, or they might be stretch bolts   

For the sake of it, replace them, its a big job again if something shears/works loose/snaps..

i reused all of my bolts, only things i changed was the washers for the water and oil banjos.

youll need a turbo intake pipe too
