i am planning a suk through turbo package for an a15. i have a few questions though as i have previously never been able to get a setup running well in the way of cold running, throttle responce once its been idling for a while etc. they do make plenty of power from experience though. in previous attempts i have desighned the setup so ther is very few spots for fuel to puddle up other than the compressor. my question to all the guys running draw through kits is can u guys get them to be resonably drivable without stuttering and how can u manage soo much boost without any real form of cooling. eg ive heard claims of up to 25psi being used. any help would be greatly appreciated as i want this to work this time. i no it can be done because a mates factory sigma turbo is like a dream to drive.
