Can you K swap a 94 Civic Coupe and how easy would it be? I realize anything can be done but is it worth it? I’m new to cars not so new to JDM my first car was a 97 Honda Accord that got stolen. 😭 At that point though I knew nothing about engines, swapping etc. at this point I’m familiar with most motors from B series to K. My knowledge is all book and forum and no practical. I have a chance to get a 94 civic coupe for $500 it has D15B7 which I know can be a good tuner motor but I like the new tech and a K20A2 is what I’m looking to buy and swap. If there’s already a forum for this please direct me. 🙂

 

Thank you for all the background on who you are and why you want a K20.

Here is a useful guide to doing a K swap on a '94 Civic coupe:

How to K swap a 94 civic coupe

 

k20a.org

Hybrid-Racing has a full guide you should acquire as well off their site.

I would not advise doing this swap if you don't have at least a moderate amount of comfort/experience doing this type of work.

 

Ima newbie and this’ll probably be my first swap I know I picked a hard one but I have a friend who does LS swaps if that’s any constellation… he seems confident. Is there an alternative? I want 200-250WHP daily driver that’s reliable and K series is amazing.

 

Thank you so much for the help both of you. For the links and the direction. I appreciate you not clowning on me I understand it’s like a right of passage per say lol. I wouldn’t have been mad ha ha if you can’t handle a little banter you shouldn’t be in the car community.

 

Also I’d like to add I’d like to avoid a turbo and prefer superchargers. If I could get 250WHP with just a k20A2 new headers, pistons, etc. I’m cool with that.

 

Might want to just pay a local tuner shop to do the swap. You’ll save yourself the hassle. K swapping a ‘94 is nothing like a B series swap. It requires cutting into where an old engine mount goes and replacing it with a new engine mount.
if you want to get 250whp, you can do it with an all motor B series and it would be much more simple.

 

Thanks for the info and I actually have an update on this I ended up buying a 97 Honda Civic with a mostly stock 1.6 B series motor in it I’m not sure what the model is yet. He just told me it was a B that’s bout it. Idk if that’s enough liters to push 250WHP without blowing it up lol. I pick it up next weekend after he raise it back to stock height. Rn it’s on ksport adjustable coilover with a camber kit.

 

Build a B20 short block on the side with high compression pistons and forged rods. Save up for some cams and valvetrain on the B16 head that you already have, and when you're ready use your existing B16 head on the B20 block you just built.

Look up build threads from people who have done B20VTEC builds, or read some of the "All Motor/Naturally Aspirated" subforum, it's a very common build.

250WHP will be out of the ballpark but a properly built B20VTEC can do 220-230WHP all day with no complaints. Paired with a short ratio transmission like an ITR or B16 trans, it'll rip.

If you're willing to give up air conditioning you could also look into the Kraftwerks supercharger kits for these cars. They work well and produce more HP than an N/A setup, but require removal of air con.

 

Awesome purchase. Sure you can make the 250whp, but it will require either a turbocharged system or if it’s all motor then an engine rebuild.

 

Ok… so I have some bad news. The civic that I ended up paying for… The day I tried to pick it up the guy gave me my money back. The went on to tell me he sold the car to a buyer who offered more. So now I’m in a whole different scenario and I feel bad cause you guys have me awesome advice! But.. I’m going to have to abandon or delete this thread not sure how that works and start a new one. Tomorrow I’m buying a 1989 with a 1996 JDM 1.6L Engine (Same Size Motor &#129315 Non Vtec Honda CRX for 3 grand it’s worth 5g’s (body, functionality, and parts). After a long search and a lot of dead ends I’m getting the car I wanted in the beginning. I’ll be starting a new thread or look at current threads for builds for 200WHP-250WHP if possible. I understand that that’s a lot to ask from a 1.6L. Also idk what series it is just know it’s JDM

 

You can keep this thread going and let us know if you were able to purchase the 89 CRX. A picture of the engine bay will help.

 

I actually just got it home an hour ago I can take a pic of the motor real quick for sure. I’m really happy!

 

 

It looks good so far. Do you still want about 250hp? If so, the easiest way to obtain it would be a turbo kit, and would probably require removing the A/C unless you get an A/C compatible kit. You could probably make 250hp on stock engine internals if the tune is good and it’s in good condition, but it would be near the limit of what’s safe for a D series.

 

Ok, so I’d rather not risk the reliability of the vehicle for 250WHP if that’s pushing it’s limit or just about there. I know every one likes to turbo there Honda’s but turbo maintenance isn’t fun is what I keep hearing and costly. What’s the max reliable WHP that can be done if I Pro-charge what I have in my car already. The guy I bought from got the motor from Japan and threw it in this CRX for his son (he’s a mechanic). Lucky for me his son now wants a Nissan Skyline The Godzilla. I’ll add he’s 10 lmao. Also this is my new baby so I’m ok not pushing her to 250WHP tbh if I can get to 200WHP I’d be a happy camper. In most of the forums I read if it’s not an H series, K series, or an insanely put together B people get a lil heated when you want a 250WHP D series especially when it’s a 1.6L. (More displacement would work, 1000lb of boost, & etc followed by roasting) ha ha ha

 

You have a D series engine, and the way to identify which type it is, the engine code is stamped on the front left side of the engine block, to the left of the exhaust manifold.
I’m not sure what you mean by “pro-charge”. There are turbocharger which hook into the exhaust, super chargers which connect to the intake manifold, and all motor which means there are no power adders. All motor usually means upgraded high compression pistons, camshaft, intake manifold, header, valvetrain, etc.
200 horsepower is obtainable on either of these routes. With turbo, you might not be able to keep the air conditioner though, depending on the kit.

 

Gotcha I’ll go take a look. Also from what my understanding is a pro charger is a form of super charger that has some better benefits. I’ll have to find a picture and a model and throw it in the chat. Also once I find out the motor type I’m assuming you guys can better assist me on the type of upgrades I need I’m assuming.
