HI guys

I recently swapped in a ca18det into my 240sx.
engine is completely
running stock 240sx fuel pump

So what is happening is that the car idles ok/rough.
if I rev it up slowly while parked it goes ok.
if I try to rev it up quickly it bogs and fights at 3000rpm.
when I take it out on a drive it does the same thing, but anytime I really hit the gas it completely bogs out and does nothing.

Ive checked the engine codes and I have one for the throttle sensor, and one for the crank sensor. I replaced the tps and it didn't fix anything (and it is adjusted proper)
The crank sensor is still there

Clear the defaults, if they appear again check the sensors and wiring.
If it had been 2500rpm i'd have said MAF problem. 3000rpm is something else, so i'd say massive boost leak and/or dead fuel pump if the sensors and wiring are ok.
