ive read plenty on this swap. so no flaming =P and yes i read the spring break swap.

Heres the situation, have a 89 coupe with a 95ka and a nightmare harness that some retard b4 me did. half s13 sohc part s13 dohc and some fuckin plugs from a s14. Im thinking that i shold try to get a full s13 dohc harness or sohc harness. and redo the engine harness. But i have a sohc HUD. My friend has a 89 coupe with 95ka with sohc hud pretty much exactly the same as what im trying to piece back together since dude b4 me fucked shit up. I guess my question is can i use sohc harness and ecu with 95 ka? i dont know how my friend has the tach from the sohc hud working if hes running either a s13 dohc ecu and harness or s14 harness and ecu. I would take a look at my friends car but he works like 50 horus a week and has a wife so its kinda hard to take a look at it

hud will work regardless of motor as along as it's hooked up properly.
tach has less to do with year/generation than it does with whether or not it's DOHC or SOHC.
I think getting an S13 DOHC harness would be extremely beneficial and would simplify this alot. Does it already have the external coil and coilless distributor?

i have the s13 coil and s13 distributor. so for the tach to work with out switching to a dohc hud tach i would have to use the sohc ecu cuz the signal runs on volts and not milivolts. the harness plugs that are by the fuse box and battery are s14 i believe because there is a retarted triangle looking plug that i havent seen on any other s14. if i cant get it fixed tomorrow im going to try to locate a dohc harness and see if i can use sohc ecu and hud. who ever did this car tho was retarted. but ill take some pics of the car and the plugs and post them so u can get a better idea of whats going on
