Been awhile since my last post but recently my car has been driving me nuts. I have a 91 with a S13 blacktop and recently everytime a floor it the car gets to full boost (7 psi) fine then it feels like im slamin on the brakes randomly. It accelerates fine under regular conditions like driving to work but if i really give it some gas it bogs down randomly and it just started doing this any advice would awesome.

Thanks

 

vacuum leak

 

check all couplers and pipes and wastegate

 

do an ohm test on your injectors while you are at it.

 

i think i found it... the coupler on the turbo outlet to the hot pipe has a pretty big hole burnt in it from my megan manifold. anyway of avoiding this again in the future? like a mini heat shield or something?
