ive got a few questions about the japanese motor, hoping some of you could help me out...
1. does the jdm motor have different specs than the american engine?
2what is the highest amount i can adjust my waste gate without worrying about blowing up my engine or turbo?(not sure how to word this about spacing it)
3.will i have to upgrade my fuel injectors?
all input would be greatly appreciated

 

1. it has less emissions equipment
2. you can't mechanically adjust the wastegate arm. it's not adjustable like on other cars
3. depends what you're doing with it

 

oh i thought i could put a spacer in it, how much hp can the stock fuel injectors hold? i think ive read 250

 

noooo. too high for stock injectors. if you just raised the boost without doing at the VERY least a fuel pump youll pop it. fuel pump and 720cc secondaries and you are good for 250-275

 

1. same. except its missing the AWS, and S4 lacks the EGR valve
2. mazda put the actuator on the BACK of the compressor housing, you can't shim it
3. no idea, it depends

 

okay thank you guys very much
