The Car took more hours than expected, but we're very happy with the results.

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....
Thanks for chiming in Elbert. It was a pleasure to bring this back to driving again and being part of the memory. We really appreciate you choosing LHT.
You picked the best of the best to bring your EF back to life. Thanks for saving another classic Honda and keeping it on the road
@@michaelc5019 Thanks so much for the kind words. We love this stuff and like to share
I did replace the 'new' ACDELCO starter (Denso motor) with the old one I still had (also a rebuild but with a MITSUBA motor) and now it doesn't grind anymore on starting (note that the starters look exactly the same on the outside).
I got and an alignment done and the car drives perfectly straight now with the steering wheel in the middle.
Next I got to address some pre-existing minor issues such as the oil pressure light bulb in the instrument cluster not working, the speedometer needle wobbling and the cat. converter rattling (will probably replace it with the rest of the exhaust).
@@ElbertWR That’s great Elbert. I’m glad I was right about the starter. Easiest fix.
I’m also glad it’s running well.
From high end cars to old school hondas...this channel sticks to its roots.
Thanks buddy. I still love the same cars from when I started the business in 1996.
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.
Sorry to hear the ending. What a fun time that way, the import scene is still alive and well, but those were simpler times.
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."
If the business isn’t making peak money on restos, John needs to charge way more. Especially at this expert level and with the results. It’s legendary motor car without the museum level (which is the best way imo).
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!!!
That's a lot of work. I just hope to drive mine around with a little more power then stock...
This is why i watch this channel love the compassion these guys have I've shared this video with like 4 people already lol 😅
Thanks so much my friend. We are so lucky to do what we love.
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!
I haven’t seen a ZC is 20 years. Kick ass motor.
Ah man, this video takes me back to the good ol days. The TLC shows through with each video.
Thanks 🙏
Geez, this motivates me to get my '90 wagon back together and off the jackstands. Thanks guys!
Ahh, the humble ZC. What a classic. Lovely work as usual, John!
The great little bolt in swap . We did tons of these back in the day. 👍🏻
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. 🙌
This turned out awesome
Amazing job 🙏🏼
Thumbs up before the episode even starts!
You guys really put your time & love into this really nice!!!
Love the attention to detail you gave even cleaning up the engine bay, class a work.
This brings back so many memories! Great job on bringing that old girl back to life!
Always love when you bring out the scrapbook. The goldern era
you guys are smart
My first whip. Beautifully built brother!
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
Nice, nice. Engine bay looked good
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.
Sorry for the novel John, I have always loved my Hondas. They're my favorite brand. My first car was a 1979 Civic 1200 4 speed, and I also had a 1986 Prelude 2.0 Si 5 speed (the first year for PGM-FI) that I bought off of a lady who bought it from MotorTrend Magazine. The title even showed that it was their test car for 1986.
Best of the best 👌🏽
Very nice work love from Toronto Ontario Canada ❤🎉
Love a build video like this. s2000 and CR-V driver myself
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.
Yep. I was never into the tail lights but I did once have a set of white face gauges on my Crx.
They are a little worn now and I can't find the clear tail lights any more, but I did find a set of black Altezza's that I will install after It comes back from paint and body work (later in the year, need to save up first).
Good job 👍🏼
would love one in an EF sedan
I remember place racing mounts.
Omg I had the same car in high school I wish I still had it 😢
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.
Would love to see this car get a full updated package for exhaust/brakes done!
You got my sub!
Great ! Please check out our playlist for more EF content.
Ooooh love this. The old btch pin. Had an 89 Si hatch. Now 88 CRX.
Watching the end .... rear end.... the tail pipe... 😊
Lol
Wish i could ship my em1 to have you guys finish up my h2b
#LHTPERFECTION
wish my ep3s paint looked that nice
Nice ✌🏻🇳🇱
I always thought about installing an hf 5th gear into an si transmission that way you get the best of both world's.
dohc zc swap the world!
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.
Wish ya’ll had a shop in CA aha
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?
We don’t have access to motors. If you’d like to supply the motor we could certainly help you with everything else.
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
Where do you get your time in belt on water pump for that ZC Engine
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
The customer supplied the parts. I couldn’t say
@@LHTPerformance okay thank you!
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?
You pretty much answered the question. It’s a direct bolt in with no need for custom parts or kits. It’s more plentiful than the original motor and makes more power.
When the 2nd D15B1 engine finally gave up, I considered my options. Finding a low mileage B series motor for a decent price is close to impossible these days. This ZC had less than 70K miles on it (documented, because the supplier imported the whole front end of the Japanese CRX it came from). A B series engine would have need a very costly complete rebuild. Plus a lot more specific parts, transmission, wiring, etc.
For me the goal was not to turn it into a super fast racer, but rather a reliable runner with a little more performance with a 'reasonable' price tag.
@@ElbertWR ah so cool, thanks for the detailed explanation! Definitely makes sense. My first car ever was a 1990 Civic DX sedan 5spd and honestly I still miss it for basic commuting. I hate to sound old, but it really seems like cars back then were just more reliable/durable and easier to maintain or repair - but i remember exactly what you said, super easy to upgrade the lower model car with a lot of parts from the higher trim levels.
Why are you guys so far away from California 😭 my s2000 needs you guys!
What degreaser are you guys using, looks like brown royal or fury from oreilys
Trade secret. After many years and trying many different cleaners, it’s part of our TLC.
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.
The customer supplied the parts. I’m not sure where to find one now.
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?
Was that a maestro???
Rover 216
Why don't you guys own a vapor honing cabinet?
When and why did you move to the U.S?
Why didn’t you clean the engine bay when it was empty?
I wasn’t originally in the plan as it was more work than planned for. Just couldn’t let it go without a clean up.
@@LHTPerformance I found an ‘06 Accord Sedan manual 3.0L. 77k miles. What’s your take on that motor? I currently have the 3.5 in my pilot with 190k. I haven’t done the t belt job, our plugs yet and I haven’t had one issue… yet. I like the idea of a manual V6 Sedan.
