Well... It finally happened...

Over the last 12 years, I've owned a few Honda Civics, each of which had a d-series under the hood. I've gone through two blown y8's and two blown z6's... The last of which was the most heartbreaking. If you ain't broke it yet, you ain't trying hard enough!

My last build was an NA d16z6 that was making 158hp and 116trq to the wheels on a Mustang Dyno. I had built a custom 5-speed S40-B000 transmission with Quaife LSD and short-ratio gearing with a carbon synchro rebuild kit from Synchrotech. You can find the build details on DSO.

This past May 22nd I took my car to the track like I usually do during the track season and disaster struck. An exhaust valve snapped at the neck and destroyed the head and block.

Initially I was planning on building either a d15b or a d16y8. I already had everything ready to go, I just wasn't going to spend the time and money on internals. Then I got thinking... I wanted the same power, if not more, but with OEM Honda reliability and durability. A friend who deals in swaps had an OBD1 JDM GSR with low kilometres in excellent condition with an S80 LSD ITR transmission. I picked them up and now the swap is complete.

I've made the following modifications:
- Integra Type-R intake camshaft
- Skunk2 intake manifold
- 66mm Skunk2 throttle body
- Skunk2 intake filter with velocity stack
- Exedy clutch
- Competition Clutch 12.3lbs flywheel
- GReddy 4-2-1 single-piece header with 2.5" collector
- 2.5" exhaust
- Innovative transmission mount with 60A poly
- Innovative engine mounts with 75A poly

The intake piping coupler was too small for the larger throttle body so I attached the filter directly to the intake manifold. Once I get the correct coupler I'll be moving the filter to correct position.

I removed the AC and was planning on power steering but the pump I received was not the right one. So for now, no power steering.

It pulls very hard and the VTEC crossover is much more aggressive than my d16z6 was.

I've attached videos of three acceleration tests I made this evening and a pic of the engine bay.

It's been an incredible 12 dedicated years to d-series motors. I've set out goals that I've achieved and although short-lived, I'm happy that I made them a reality. 158whp in an NA d16z6 is no small feat! DSO has been my go-to for EVERYTHING I've done in the last 12 years. I may not be rocking a D anymore, but I'll always come here for information and advice.

See you at the track!

Looks rad in the bay. I have a newer civic now for daily duty and I have to admit the mid range of the bigger motors is nice. Bit I still find I need more.

Thanks! I've been taking it out as much as possible given the fall weather here in Toronto (Canada). I'm really enjoying it. I've started to try opening it up a little more, pushing it to 8000rpm at full throttle. It screams from ~5500 to 8000. As expected with an older transmission there is a grind in third and occasionally in 4th. The short ratio of the transmission feels perfectly suited to this motor. I'm hoping to get it Dyno tuned before the end of the season.

Awesome swap. Had a b16a3 swapped del sol few years ago. I didn't do the work, but it was a fun car. Plowed through the snow and handled well. Sits at 4k rpm cruising down the freeway lol. Would love to have another b series swap. Any other major plans down the line?

Hey EJ8Noob.

I'm surprised that you took your de Sol out in the snow! I bought mine from my brother-in-law back in 2012. He was the second owner and it never saw a drop of rain. I almost never take it out myself. It still only has 167,000 original KM, but obviously not the motor and transmission!

With the ITR transmission it seems to cruise at around 3500-4000rpm as well. Not a big deal since my custom built d-series transmission did the same. I honestly think I'm going to keep it as it is, other than installing the RDX injectors that I still have sitting in a box. I had my fun building my old D but now I'm looking for decent power with Honda OEM reliability.
