I emailed forge a few months ago and they send me a test valve from the pics i sent them. they also sent a spring tunning kit with 4 springs, blockers which fit and 3 spacers. i was advised not to use the red and blue spring as there were for bigger turbos. so the only springs i can use which is the weakest is
green ( 6 to 8 psi )
yellow ( 10 to 12 psi )
blue ( 14 to 16 psi )
red ( 18 to 20 psi )
The valve blockers etc all fit perfect. but with the combinations with green. ive tried yellow. then green with 1-2 and 3 spacers. but it drives for about 5 mins down the road then the engine mangment kicks is with traction control light/active stability control system light kicks in. Im not sure which system is messing with but i think its the active stability system as it stays on untill the engine is stopped and the valve removed.
I received this from mitsy
Dear Mr Robinson
MITSUBISHI COLT CZT
Thank you for your e-mail received on 7th November 2005.
I have been informed by our Technical Department that a standard value
for the Turbo boost pressure is 39-65 kPa.
I trust this information is of assistance.
Yours sincerely
