need help with motor

By blk92hb
- Fri Jan 29, 2010 1:48 am #171804 ok i just got my jdm b16a im my eg its been in there for 8 months but ever since its been in there my tach would work up to 4k then bounce around tell the rpms come down. also at high rpms about 5500-6k the motor bogs down then the vtec kicks in and go's. now its a stock motor i have a s2 intake manifold, aem short ram cai, a full tune up new plugs, wires, dizzy, and fuel filter, the exhaust has a high flow cat, a turbo muffler and a dent in the manifold :x i got it like that :x the timing is also on mark. thanks in advanced

also just to throw this out there what would happen if i put my z6 tb on the b16a

He had a loose wire on his ecu plug that went from the ecu to the dizzy. Check those, thats where i would start. Also check your Ignition control unit and your coil :thumb:
