95 Honda Civic Si (automatic)What is a Compatible engine swap???
 

Hey Guys,

I need your help. I have a 95 Honda Civic Si SOHC V-tec and I want to swap a new motor cause it's getting old. What engine can I swap it with that will a directly fit and no need to for any modifications.

I asked around and people say to get a D16Z6, ZC SOHC V-tec or D15B. i'm not sure if I can just drop this in and i'm good to go? Do i need to change anything in the ecu or something?

Please let me know.

Thanks in advance

You already have a d16z6 (someone correct me if I'm wrong).

How many km's on the motor? Still runs ok? Any problems?

No point in swaping for the exact same engine unless your current engine has some severe issues that can't be fixed.

Pretty sure it's a z6 but there were a few auto Si's that had a slightly differnt code that I can't remember but they were basically the same as a z6 just from what I've heard, never shown any actual proof, they had a slightly different intended for use with the auto trans since it has differnt gearing then the manual version.

I would suggest leaving it alone, if your motor is hurting then maybe pull it and have it rebuilt, 92-95 engines are getting rare, in good condition is almost impossible, better to build what you have and know what's under the hood then toss in an unknown motor and hope for the best.

@MPR - My engine just stop working, I was driving home one day and when I turned on the car I felt a constant shake, almost like im running out of gas feeling. I was able to drive it to my cousins house for him to check it out. He said I was running on 3 cylinders and that they other one is not working. We did a compression test on the one that wasnt working and it show 120 lbs. I heard low compression in one cyclinder usually indicates a bad exhaust valve.

I'm not really sure what to do? Try to fix the problem or put in a newer engine. My engine has about 230,000 kms at the moment.

I need your suggestions!

Thanks,
Marc

^Was it blowing white or blue smoke out the exhaust?

If you had a broken valve, you'd have 0 compression on that cylinder. The fact that you still have 120 means either your rings are shot or you have a blown head gasket.

In your situation, I'd at least pull the head off and investigate. If it just needs a head gasket, then it's an easy fix.

Need you suggestions!! PLS. and TY :-)
 

Please reread below. :-)

@MPR - Thanks for the suggestions. I think i'll tow it to a shop and have them investigate a bit more. The reason why i'm resulting to a newer engine is because I don't want to deal with any more issues but in the other hand you would never know what's wrong with the newer engine.

I appreciate your help. All the best!

Exactly what mike said. If it holds no compression then its not a valve. Unless it had tons of carbon build up and was just jamming the valve seat, which is not too common though possible. How were the other 3 cylinders for compression?

Buying a "new" engine is always a headache. All the people drive civics like they are race car drivers, thus beating the living hell out of the engine which was never meant for redline shifts every damn time people shift.

A basic rebuild will cost a bit of cash, especially if you do not do any work yourself. a d15b is basically the same engine as d16z6 as long as you get the single stage vtec model. You can still find a healthy d16z6 that hasnt been demolished, but it takes a bit of patience.

@D.T.P - Thanks for your post. The other 3 cylinders are fine but when we took the spark plug out of the one that wasn't working the bottom of it looked dark black. I'm not sure what that's suppose to mean?

I was looking to just purchase a D15B SOHC VTEC from a JDM Engine warehouse in Toronto. There's actually a couple of them to choose from but the average price was between $450-$600. Plus I also have to pay for labour to do the swap. Which do you think is the best way to go?

Rebuilding the engine, im not sure how much that will cost around or $800 engine swap with installation.

Thanks,
Marc

well rebuild will cost more. You have to pull the engine out, take it apart, surface the head, hone the block, possibly micropolish the crank, then new rings/bearings/headgasket and bunch of other gaskets including timing belt and water pump. Then assemble everything and re-install. Would guess you are looking at about 1500 if not more plus a week at least for turn around.

Just get a new engine. D15b are good engines, just make sure it has one vtec solenoid and not 2. You should be able to run your stock ecu and have it run decent.

What he said. I just swapped a D15B into mine, sourced it from Tiger Japanese for 600, and with only 25k kms.

i have a low miles in sweet condition 95 civic motor out of an old couples car willing to trade for a 96 v-tec in same condition. this motor has everthing still bolted to it. it was due for an oil change and the oil in it looks bran new. it has a manual trans with it but i might keep that. any trades will be straight across but since this is a rare find for you we can do an even trade if you pick up the shipping. i'm near fresno, ca. shipping should be a breeze. also this motor will start and run perfect with out even putting plug wires on. you will know imediatly you made a good deal. i expect close to the same. or $1,500.00
