Mk3 Turbo & Actuator

Just wondering, what is the most bhp a standerd mk3 turbo can take and the most psi the standerd mk3 actuator can take??

Thanks Rab

turbo wise with supporting mods your looking at 200-210 bhp on a k03

as far as the actuator dont go playing with it just get the car mapped so the fueling is spot on also, messing with the actuator is asking for trouble

Another one of these threads :rolleyes:...myki 220bhp on a k03 are you sure...??? If it was possible then surely it would only be with huge boost spike with that power for about a second then not long before it goes pop...but are we talking a maximum reliable bhp for the k03...if your planing on trying to max it out then dont be expecting it to last long...you wont need to do anything with the actuator on stage 1...altho im going to give mine a slight fiddle when i get my boost gauge all fitted...

Yes 220bhp is possible with the right mods mate. There was even talk ages ago of Alex now at backdraft, running near 250bhp on a K03.

250...must of been a freak k03 on steroids...considering most people on stage2 on a k03 only just manage about 210 although i spose it would be mapped for reliability aswell...

Forge do an uprated actuator for the K03, is this really a replacement if the standard one fails?
doesnt look like a bad bit of kit that ver adjustable also able to take it apart for a service which is allways good...:)

K03S has:

8 blades as opposed to 12 on compressor wheel
Compressor housing is 39.5ml opposed to 37ml
K03S Turbos have 0052/0053 in the serial number and they usually are 704D/704S/704T
Larger main vein and larger continuation
Only one vac line off of the actuator (2 on K03)

You can get silenced and unsilenced K03S turbos, but not silenced K03s
