Bought this car a few months ago and it currently has a d15b7, but the engine wont pass smog, which is most likely due to the lower end. Got the top end rebuilt so i know thats all good. The car ran good for a while, but the timing still seemed off, and later on down the road, the car just stopped wanting to turn on due to what i think is a skipped tooth on the timing.

My main concern is if i should rebuild the bottom cause i know the pistons need to be replaced anyways. Or would i be able to put in a b16 with this car sitting as a gross polluter?

Was originally going to swap a d16 from a 97 into the car and make it OBDII, but since the car didnt pass smog, this wouldnt be possible unless i wanted to take the chance of it passing the BAR inspection.

Wondering why you haven't verified the timing is off before rushing to try and rebuild the bottom end.

 

Found out the timing was off after i bought the car.
Got the timing belt, water pump, and tensioner replaced
but my timing issue was still present.

Also changed a few sensors, new filters, plugs, wires, rotor.
Basically did a full tune up while doing the timing belt.

Only thing that is really left is pistons, rings, and rods but at this point i would
rather just swap the engine incase any more problems end up emerging.
Only issue is that its sitting as a gross polluter.

Since the b16 was put into some civic's of that year, i should be able to just swap one in there without any problems, or am i stuck at smogging the car with the D15b7?

 

Er. HOW is the timing issue still present? Did you actually time it? All you said was that parts were replaced. What is off, ignition or mechanical timing?

 

I didnt put in the parts myself, and i know my friend didnt use a timing gun. Just lined everything up how they should be. Looking up the part numbers for the belt, on one site it said it was for vtech, and on another it said it was for both.
So dont know if thats the culprit. I do know that my oils rings went out and thats what causing it not to start in the first place but even before then i was still blowing a lot of smoke at the higher revs. Have yet to do a compression test so might get to that soon.

 

You can rent timing guns or just spend the 39 ish dollars for a cheap timing gun that will still do the job just fine. Also doing a compression test isn't that hard either if you have the compression tester.

Spend a few dollars on your tool kit and it will save you a few hundred dollars in guess work along the way.
