I just did a motor swap from a 90 to a 93LE with 110k. This motor 93 motor had this issue when it was in the other car(93LE). Now with the turbo intercooled set up, it sometimes shuts off the engine. Does anyone else have this issue and how do i get rid of it?

Other than this issue, the new motor is running GREAT! I figure i fix this issue before I get into my wideband, new 2.5" DP, and my emanage blue.

Oh, 2nd thing is, i m in the market of a new down pipe, Tonys or Corkys?

 

Is the same MAF being used? What other controls are being used for both?

 

Do you have a blow off valve on it? Recirc or vent to atmosphere? Blah blah blah. I have two BOV's that I had vented to atmosphere, both had stalling problems because they're just big vacuum leaks. When I put the one way check valve on the second BOV the stalling issue ceased.

 

same MAF from the 90. I m using a HKS SSQ BOV. but this engine had an idle droop before in the 93 body w/o turbo. so the problem was there before i swapped it and turbo it.
