1Jz conversion problems

[bryanfain]

I swapped a 1j from a soarer in to my s14, its a auto ecu. runs good until it hits boost, the moment it gets a positive pressure it just sputters and spits and wont hardly run. any ideas?

check your plugs. What are they gaped to?

[bryanfain]

plugs are new and gapped to .8 , changed the coilpacks, map sensor, calibrated the tps.

.8 gap? Usually they say the 2JZ should run a .32 gap.

.8 is too big of a gap. Most NA cars normally run .44-.46. Gap them tighter and problems should go away. I like .28-.32 for turbo cars.

0.8mm is 0.32 inches dumbassess. Is your 1jz map or afm base? If yours afm base, you blew a coupler.
