ok so had this running a while ago now, the bonnet somehow shuts and clears the motor even though i cant understand how by looking at it... anyway got it tuned on friday and went to drift prac, due to only having a t-sereis in the back i asked the tuner to run spring pressure off the wastegate and she managed 220hp atw on 7psi! once i fit a suitable F or G series diff ill wind the boost up but for now itll do.

Had awesome fun at drift prac, the increase in torque was more than i expected and even with only 220hp she was baking 4th gear hard! felt really good after all the work and long hours staying back late at the workshop.

Although she has now developed another problem. when i did the motor swap, i also fitted the SR vac line from the motor to the brake booster, including the check valve that came with it. what has been happening now is that its locking up the brakes when it sits and idles for about 10-15mins. as in i can jack the car up and itll take a fair bit of effort and both hands to spin the front wheels... so i thought that was it for the night so went and sat down to watch the other guys do their thing. came back 30 mins later and went to demonstrate the problem to a mate and it had now freed itself up! spinning as normal! so went back out drifting only to have them do the same thing (expectedly) once i got back in the pits and let the car idle to cool down. i literally had to spin the back wheels to get it on the trailer.

so the next day i checked that the check valve was the right way around and it is, checked all the hard lines, all good. had the master rebuilt not long ago and bled the brakes so wont be that, checked the slides on the calipers, all good... do u think it could be a bad check valve? it never used to run one before and never had a problem...
