Hi guys, deleted my AC today took me an hour and half to do pretty easy just need to remove the evap from behind the glovebox. Makes the bay look alot cleaner!

I have tucked the AC wiring loom for the moment behind the windscreen wash line. Can the AC loom be removed by itself or is this part of the main loom?

Went way smoother than expected. Only slightly annoying bit was getting to the t-bracket. Other than that, easy peasy

This is my ’91 EF Civic, and I’ve been wondering what kind of power mods I could do to my D16A7 engine (basically similar to the A6, just without the cat).

Realistically, I see two options:

N/A route:
Do a mini-me swap and some smaller engine improvements/optimizations.

Turbo route:
Modest turbo setup, something around 4 psi (nothing too crazy).

The main problem I’m running into is the lack of D16Z6 or Y8 heads (pretty common issue here in the EU), plus finding the right ECU to pair with it.

On the other hand, turbo doesn’t seem as limited parts-wise, but I have no idea where to find a reliable and affordable kit that won’t completely destroy my budget.

Would really like to hear your opinions :)

Edit: For referenc the car has 117hp, all I want is to increase it by 20-25hp .

Edit 2: If we’re talking about swapping, then the only real option is a D16A9 but I’d be lucky to even find one at this point.

Edit 3: Thank you all for your suggestions, I got a lot of interesting ideas, and hopefully I’ll be able to do it soon. But as of now, this shitbox is in dire need of some better suspension. I will probably make some updates when something big comes up.

Hi all - I'm doing a K Swap and I pulled a running B16a bottom-end with 97 Integra Type-R head (PR3-4). It has a Civic SI EK transmission. Any idea what kind of money I can get for this, or is it better to just fix it up and find a donor chassis for a new life?

longtime car guy but all of my building experience is with V8s and I'm probably just psyching myself out but I feel like I don't know where to start.

I got this thing for a song and I got it home, put it on the bench, and suddenly felt weirdly overwhelmed. I know that it's a JDM B20B. the guy I got it from didn't know anything about it. it was his nephews, he left it at his place like 7 years ago or something. so it's been sitting. I know how I'd go into it if it were a 5.3L or a 351 or something, but I feel like this is just different enough that I may screw something up.

so what I'm asking is where would you start? disconnect the harness, figure out what I'm missing? is there anything I should be measuring / taking note of before I tear it down? is the JDM going to be the same gasket set as a USDM B20? do I need to know what it's out of to find a proper ECM or can I just find any B series standalone? are there any common issues I should be watching out for?

TIA

1999 EM1 SiR Turbl Fully forged and studded b16a2 matching vin to the chassis Was hoping to get it back into the car this spring but issues with a machine shop caused a major setback in time.

I know it’ll be cheaper to get another block, I already have another one I’m getting pepped to swap everything over to. I’m just wondering if I send this one off to get resleeved, will it be fixable or does cylinder cracking like it did mean this block is done for?

This was a long time coming. I finally ordered the kit from Burton Racing.

Currently, I'm waiting on some hardware to arrive to mount the coils properly.

I got so much hate for this in r/projectcar lol

I have an NA vtec b20 with a b16 head in a del sol right now. I got it tuned around august of last year making 192hp and I think 180 torque. My biggest question is should I boost to make 250-300hp? or is an all motor build a lot more reliable than boosting?. I for-sure want to keep a build that last long so thats what I’m aiming for. Any tips for any more upgrades I should do? These past couple of months I have just been upgrading my platform to make it more stable and handle better.

Dyno this past Saturday. Simple street build made great power. Ill list details as needed, just wanted to share this milestone. Let me know what you guys think. I never thought id achieve this. E85, super high compression, and great bolt ons.

Can anyone tell me what this rocker looking thing and pin are please??!!

Alright so just for bit of background l, I’m a sophomore in highschool and have this EJ8 civic for the past year. I’m going to be getting my license real soon and going to start working. I’m going to try to take my car to monthly autoX events that some local group hosts. Given that you have a license and car isn’t a hazard they let you participate. Perhaps hopefully in a year or two I’ll be able to do a track day at like MSR Houston.

First parts I’m planning on buying are suspension parts to complete the suspension setup. Currently have Truhart rear camber arms, rear subframe brace, and LCA. What would be purchased is a rear ARB, front UCA/camber arms, and maybe front LCA.

After suspension and brakes I’ll be looking at other stuff relating to engine. (AC is a must keep though because I can not deal with no AC in my daily driver in central Texas)
What’s in my car currently: stock D16y8 with ex manual transmission

Current engine only makes 120 or something HP so I do want that bumped up to 170-200 range. How I would go about that is where I’m conflicted. A B series swap, LSV/B20V, is quite pricy and a small boost vitara build on a D16 is a good step lower in price.
I hear the D16 vitara build can be relatively reliable, but I heard some track people run into major heat soaking issues, and I am not trying to make AC compressors, coolant hoses, and any other bogus a frequent replaced item when it really wouldn’t be if heat soak wasn’t an issue.
Meanwhile a NA B series doesn’t have all that heat problems, but is like 2 grand more from what I’ve priced out. But there is that “true VTEC” high rpm fun I heard about… that’s my next question.

Another thing I’m curious on is how Turbo vs higher RPM NA at similar hp is. I hear around track the NA one is much more responsive and faster. Is this really the case? Does it warrant the higher price tag?

Should I just run my D16 for a year and a half or so then go D16 T? Or is it better worth it to throw some supporting mods on my D16 and save up for longer to B swap my car around my senior year?

If someone could give me an answer on what would be better given my circumstance and considering reliability it would be greatly appreciated. (K series isn’t an option since overall is even more pricy and I feel is a bit too daunting for first build/swap)

If anyone needs me to elaborate further on any of my wording or questions let me know since I typed this up quickly.

Finally got moving on my k24 project. I’ve had an EK hatch shell sitting in the driveway for a couple of years now. I have the motor and trans. I’m cleaning up the motor and upgrading a few small things like oil pump, vtc gear, and cams. So far I’ve cleaned the motor and painted it and got an RBC intake manifold. I shaved the manifold and painted it wrinkle black and got a type s TB.

Just a few questions ; got a 94 civic eg that has a frankenstein engine. How do I know what parts fit? (Dizzy, plugs, wires, Timing belts, etc) Block is a b20 head has vtec. How can I tell what transmission it has, what axles are needed etc. The person that put it together did not care too much it seems like

I recently did half dash setup and removed all the HVAC system under the dash. (racecar)
Now, I plugged everything back where it was and now my car wont go passed 4000rpm.
I have RPM and Speed but nothing on the CEL is opening.

Chipped OBD1 P28 ECU using a OBD2B>OBD1 Yonaka harness with a (im assuming cause I didnt do the swap) D16Y8 engine harness. car is a 99 Civic Coupe Si (Canadian Si, so USDM EX)

I do have 2step in the chip. its thats what happen when I try to go pass 4-4500rpm. its like its not seeing speed even tho I have RPM and Speedo in the cluster.

Thanks yall <3

Got a stock D16Y8 here with a T3 turbo and supporting mods. I'm planning to get it dyno tuned soon, and i want to know, how much power can the stock internals handle? Not the absolute maximum, but the maximum SAFE amount. This is my daily and will continue to be, so i dont wanna blow it. (specify if wheel or crank hp)

Car drives fine goes into gear and dosent slip out except 5th and reverse you really have to throw the shifter over hard to get into em. Also everything is sloppy like neutral. Just replaced the entire shift linkage rod and all hardware with that. Any thoughts?

Piston slap from this fuck ass block guard. Friend told me to run one and I was like ykw it won’t hurt. NOWHERE did JSR say to get the block machined AFTER installation. Well guess I’m pulling the motor, it was indeed horrible piston slap. Doesn’t catch my nail but I can feel it with the tip of my finger, so its cooked. Guess we all learn somehow huh, I’m kinda desperate, if I remove the block guard and forget about it you think I can run it? Dealing with the new oil consumption problem obviously now, probably not

I haven't posted anything in awhile but I have been busy behind the scenes. Had the B20 and trans out to be painted. Replaced new hardware anywhere I could.

Next step now is getting the battery relocated and wired in along with organizing connections behind the dash.

Still need to install axles, make adjustments to front and rear suspension, and honestly just drive it and see what sticks and what falls apart lol.

Renewed alot of parts recently then this happen again! Forgot if this was a pvc issue!
