ok so my motor(d15b7) is slowly going out... and i head a complete swap from my old dx coupe that only had one original owner before me and that motor has about 97xxx miles on it.. so i figured i would swap that motor into my car.. the only thing is that my car is a 5speed and that motor was in an automatic car..

so.. is there any differences in the longblocks?? would i have to switch anything around?? all help is appreciated.. thanks

Engine is identical between automatic and manual, the throttle bodys are however different between '92 - '93 and '94 - '95 though, keep that in mind, '92 - '93 uses a firewall mount MAP sensor, '94 - '95 are directly on top of the throttlebody.

yeah well the old dx that i had the one with the one owner before me was a 95.. and the dx i have now is a 95 so that means they are completely identical?? or am i wrong?

another thing what do i do about the tranny?? do i just bold the 5 speed tranny to it?

the transmission should bolt up no problem…*however ECU is gonna be something I think you'll need to deal with. not sure if it's going to be as simple as swap it over or not but I'm sure someone on here could answer that.

Absolutely 100% identical.

You'll have to pull the clutch off the old engine and remove the flex plate from the new engine, and the reinstall the clutch, make sure you use the MT flywheel bolts, the ones for the automatic flexplate are too short. then its just a case of bolting up the tranny.

ok thanks alot.. do i have to swap over dizzys?? or do i just leave the dizzy on the newer longblock

ok so i finally got some time off from work.. i pulled the motor out of my car today and was getting ready to put the better motor(automatic motor) in.. i took the automatic tranny off and took off the torq convertor or whatever its called and saw this behind it

jdm.coupe3234

am i supposed to take that off??

what all do i need to do to make my 5 speed tranny on?? i already took the clutch and flywheel off the 5 speed motor

jdm.coupe3234

any help is appreciated...

94EG8

No you're not supposed to take that off, thats the end of the crankshaft, your flywheel bolts to it.

jdm.coupe3234

oh ok so the end of the automatic motors crankshaft is the same to the 5speed motor?? thanks bro.. so all i have to do is take the flywheel and clutch off the 5speed motor and put iton this motor right

94EG8

Correct.

ok so i got everthing together and got the motor in the car!! it took about 5 hours total.. the only thing is that when i turned it on i saw a bunch and i mean lotsss of smoke coming out my muffler... motor was super quiet though..idle seemed fine.. but smoke like crazy... i turned it off and went over everything and noticed that the tps and plug that plugs into it from the harness wasnt connected.. so i plugged it in but it wasnt really connecting i guess it broke when i was putting the motor in.. so i held them two together and used a zip tie as a temp. fix.. turned the car back on and smoke was gone

jdm.coupe3234

so i had it on for a good 15 mins. and after a while i could here like wistling noice from the tps and sure enough it started to smoke.. but then went away.. i drove the car for about 5 mins and it was driving fine.. then went to the store to put gas and about two blocks away it just started to bogg down like crazy in first gear.. it felt like a fuel cut or something.... it bogged in first then like after 5 seconds of boggin it finally picked up speed so i shift to second and same damn thing happpend.. my car pretty much limped home from the store.. anyone know whats going on?

jdm.coupe3234

so far i took off the throttle body off my old motor and am going to switch it to the newer motor that i installed today.. anyone else know anything else i should do??

jdm.coupe3234
