1990 Civic with - ZC DOHC SWAP 

That's my car! Massive thanks to LHT Performance for making it run again. It runs great. Put over 200 miles on it the day I picked it up, no issues. After 2 D15B1 engines this 1991 ED6 (Civic base model hatchback) has little bit more power now. I owned it since 1998 and over the years it kept me mobile on a tight budget. These cars were truly 'bare bone' from the factory. Not even a cigarette lighter or right side mirror. Of course it was relatively easy to upgrade it with the features from the higher specs. Swapping the 4-speed for a 5-speed and putting in the SI MPFI intake and fuel injection system made it a lot better. Next I will try to save up for the paint shop....

From high end cars to old school hondas...this channel sticks to its roots.

That engine bay turned out nice! Honestly, these may not make the most money from a business standpoint, but man, these restoration/rebuild/bring back to life builds are awesome to see. You could probably buy a decent shell and throw a clean swap in it once every couple months and do decent on them and it'd be good content to watch. "I bought an abandoned EG, and now it's got 210WHP. Click to see how we did it."

Good job!! I had a civic same color with a dohc zc too. I put b18LS main bearings to keep the crankshaft from vibrating, (not many people know that is possible), D16Z6 rods, DohcZC pistons polished, block milled, head shaved, intake ported and polished with close to 13:3:1 compression, lsd D16a6 with zc final gear transmission, and a 100 shot of NOS. I would smoke B16’s and GSR’s back in the day lol. It never blew up. Take care of that thing!!!

I haven’t seen a ZC is 20 years. Kick ass motor.

This is why i watch this channel love the compassion these guys have I've shared this video with like 4 people already lol 😅

Really old school and cool! I am bringing my S2000 down there next week John! Can't wait!

Ah man, takes me back. LHT TLC for sure.

I am missing the simplicity of these cars! I had a 1991 Base Civic that I swapped to a ZC and man what a difference in power! Gas mileage wasn't all that much different but it was close to double the HP! It reacted well to intake and exhaust as well! That car ended up getting totalled and I moved the ZC to a 1988 4 door with a gutted interior and it was a beast! Loves that one! Eventually I got a 1990 Si with a B18C5 in there and that was so much fun! (I did the work my self on those cars too! ) Thanks for the throw back and I would really love to get a Civic EF 4 door again and make it into a track car!

This hits the heart. I had a 1988 cr-x from Saitama. Stock zc. I put in dual valve springs, titanium retainers, light weight pulley, act street clutch, header, tanabe exhaust with mid pipe, and a 50 shot of nitrous. Drove that car like I stole it for 4 years. Maintained it and it was the only consistent thing and my life. Someone stole it unfortunately.

Ah man, this video takes me back to the good ol days. The TLC shows through with each video.

Ahh, the humble ZC. What a classic. Lovely work as usual, John!

Geez, this motivates me to get my '90 wagon back together and off the jackstands. Thanks guys!

I have ALWAYS wanted to build a ZC and boost it. I have owned a few turbo Hondas in my lifetime. I boosted my 1992 Integra GS with a B18A2, I boosted my 1989 CRX with a JDM D15B that I swapped to OBD-1, I just sold my 1997 Civic coupe that had a FULLY BUILT LSVTEC turbo that made 709 whp at 34 psi from a Garrett GTS3582, but in the past it also had a boosted JDM D15B, and a B18B1 that I rebuilt, gapped the rings for boost, BC Stage 2 Turbo cams, and used alot of K-tuned and Skunk2 parts. It made 412 whp at 18 psi with stock internals.

Just change back to oem tails, oem headlights and oem corners, and leave old blue paint alone (or to further patina)… and I think it’ll look sweet, in a mild rat-rod kinda way. 🙌

Always love when you bring out the scrapbook. The goldern era

Thumbs up before the episode even starts!

This brings back so many memories! Great job on bringing that old girl back to life!

Holy crap! I haven't seen a set of Altezza taillights on a car for YEARS! Even the white face gauges. I always liked the AC Autotechnics 3D gauges. I had them on my EK at one point.

Love the attention to detail you gave even cleaning up the engine bay, class a work.

Nice, nice. Engine bay looked good

My first whip. Beautifully built brother!

Love a build video like this. s2000 and CR-V driver myself

I had a sohc ZC with a Isky cam, magnaflow race exhaust, Greddy header, ebay intake. She was a fun little 89 Si civic hatch

I went thru several motors in my 91 civic Si. Stock motor gave out in 02 on valentine day 😡 had a ZC swapped and used my Si transmission 0:30 in paid 1500 and it lasted 1500 miles lol then had b18a hot garbage then B16a ys1 non lsd. Miss that Si.

You guys really put your time & love into this really nice!!!

Very nice work love from Toronto Ontario Canada ❤🎉

Would love to see this car get a full updated package for exhaust/brakes done!

Watching the end .... rear end.... the tail pipe... 😊

I remember place racing mounts.

Ooooh love this. The old btch pin. Had an 89 Si hatch. Now 88 CRX.

Wish i could ship my em1 to have you guys finish up my h2b

Omg I had the same car in high school I wish I still had it 😢

Great video!!!

Best of the best 👌🏽

you guys are smart

i have an 87 crx i cant wait to swap. got a d16a1 im gonna put in it and try to autocross

This turned out awesome

Im not sure if you will see this or are already aware but i found this trick for timing on i know for certain the b series and h series cams, they have a hole in the cam rail and a dimple in the cam and if you line up them you can put a punch or something similar down to line up both cams in perfect timing every single time, I'm not sure if any other hondas series are like this and would like your feedback (if you wouldn't mind) if they are as i don't have access to any other series.

#LHTPERFECTION

Amazing video thanks for so much info! Theres a zc for sale locally and im quite tempted… any idea of what power you could get from a few bolt ons for improved airflow?

would love one in an EF sedan

I always thought about installing an hf 5th gear into an si transmission that way you get the best of both world's.

wish my ep3s paint looked that nice

dohc zc swap the world!

Amazing job 🙏🏼

Wish ya’ll had a shop in CA aha

Why are you guys so far away from California 😭 my s2000 needs you guys!

I'd eBay boost the snot outta that little ZC motor and see how much it can handle!

im interested in possibly purchasing the zc swap

Good job 👍🏼

Nice ✌🏻🇳🇱

the engine runs well. I would like that motor in my 95 Civic coupe. :) What does it cost to do the job parts and labor?

You got my sub!

🔥💪💯👍🚘🚀

So, I have a 1987 civic hatchback. How easy would be to swap a zc to it ? And what would I need to do it

Where do you get your time in belt on water pump for that ZC Engine

3 pokolenle civik 👍👍👍👍👍 y mnè akkord 3 ca2, ca5 85 -89 ,87 slepoì .xonda⚡.

Was that a maestro???

Dang I have one of these in my bone stock tgp 91 civic si I just got rust free for 2k. Mine is SOHC can I put this head on it?

Hey, I was wondering where you guys order the maxorber struts? I don't see them anymore like I use to unless is under a different name. I use to order those and they are the best brand over ebay stuff

Why don't you guys own a vapor honing cabinet?

When and why did you move to the U.S?

What degreaser are you guys using, looks like brown royal or fury from oreilys

Hi guys, can you tell where did you find a new oil pump and can you give the part number because i've been trying to find a new oil pump.

apologies in advance for possibly a silly question, but this late in the game what would be the main driver of picking to drop in a dohc ZC motor instead of a VTEC b series? I guess just cost if all you're needing is something to keep the car usable since ZC are essentially D series so transmission, engine mounts etc are all the same?

Why didn’t you clean the engine bay when it was empty?
