Honda waterpumps on these d series are built for life. They only require inspection at timing belt intervals of 100,000km or sooner depending on service regime. If you use the correct oem honda type 2 blue coolant the pump will last a very long time
The 2 IACV hoses don't have to come off. Just did mine and there was more than enough wiggle room leaving them in place. The difference is noticable, gives the engine a little more grunt especially torque down low.
I replaced mine a few months ago, and I took it to Honda to Finish it. I could not get those 2 hoses on the IACV. Getting those 2 hoses off was the worst thing I've ever done on my car, and trying to get them back on was even worse. Taking the fuel rail off would allow more room, but I don't know how to do that, so that's why I took it to Honda. I spent over 2 hours fighting with those 2 hoses, it was hands down absolutely the worst job I've done on my car. My blood was boiling before I gave up. The reason why it's so hard is because the end of the IACV those short pipes the tip is bigger making harder to slide the hoses on, and that damn fuel rail is in the way.
Bro , I hope you're joking. At the same time I wouldn't expect a Marine to be able to figure out how to get a simple hose off either. By far the easiest thing to do on a vehicle of any sort is remove a hose. I hope like hell you are not working on government vehicles
Hi thanks a lot for the video will changing this gasket give it 90 hp or is changing the ecu a must. Pleaserl respond as your the only person making useful content on this engine
Yes it is real! The manufacturer limited the amount of air, thus stifling the engine. The process can be considered complete by replacing the ECU. D14A3 - 55kW, D14A4 - 67kW
We did simthing similar on my step bros bmw 318i had a massive cone style restrictor in the intake couldnt even get it to get side ways on a wet corner near mine then did it again and nearly spun the car 😂 massive difference
I’m guessing this is done because of some kind of government restrictions. I have a 1998 Civic DX with the D16Y7 in the United States. We get all the power ............106 hp.........😝
Some D-Series engines come with 75HP instead of 90HP even though it's exactly the same engine and it probably was due to emissions in some countries. You clearly see a difference in the diameter of the gasket in which the air flows through, much bigger on the 90HP gasket. You can put a D14A2 gasket on a D14A5 engine for example which is one of them that's restricted to 75HP without a problem. I'd personally do it for the extra 15HP in these lower HP cars where it actually makes a pretty nice difference.

You won't be running lean, do this with the ECU unplugged, for at least an hour, so it resets. Then assemble everything, plug it in, and start the car. Let it idle (DONT REV IT!) for a little bit, the ECU will automatically calculate and change fueling after noticing the increase of air.
Great job, please note while this is removed it makes changing out the PVC valve out from swearing like a sailor, to a easy nice job!!!! AhahahHa I learned the hard busted knuckles way from the bottom!!!!!
I doubt it because the ecu can't make up that much extra fuel for the extra air intake. The extra air intake alone would cause the fuel map to go very lean to around 15 or 16 afr. I have this engine in my spare car and hope to bring it out soon to do some testing on this subject
