I have a 96 civic dx and swapped it with a ls/vtec engine. The block is from a 90 ls and the head is a 99 civic si. I used my original engine harness from my dx by splicing the wires to fit the connectors and a P28 ecu with a chip and conversion harness, but it runs weak.
It idles up and down by itself and runs like it's got a misfire.
Pretty much is as weak as my stock motor but with a mis. and bad idle.

What kinds of engine harness and ecu should and can i use, and is this also the answer to my problems listed above.

What should the ignition timing with a timing light be set at? I was told at zero degress, is this correct?

Thanks very much.

 

dude if its a stock block with stock head and b16 cams its gonna be weak. dont expect it to make like 180hp. its probably has like 150

 

true dat....hook it up w/ a typr r block

 

dude if it runs as weak as your stock d15 then you've got problems. something must be wrong with the wiring. try using a wiring harness from a gsr. im running a 2000 si motor with an obd1 dizzy, and ive got an obd1 gsr wiring harness on it right now, runs great. i think the only thing you wouldnt hook up is the knock sensor, no knock sensor on the ls block. Obviously your not obd1, but i believe its all the same idea.

not sure on the whole timing thing since its ls/vtec, not sure if somethings different, i just match the lines on my b16. good luck man, sorry these other guys dont wanna try and help you out.

why would you want hook it up with a type r block, thats a waste of money.

yea something is wrong if its as weak as your d15. you should be making more horse and torque than a si. you should switch out the pistons, change the wiring harness and ecu to a si or gsr w/e you can get your hands on. you also need a good tranny. sorry but i know nothing about that timing crap though. i run a si with itr parts and and lsv is obviously a bit faster than si.
