    D16Y8 Automatic Trans. Check engine came on for my IACV. At this point Idle was fine. I got a nicer looking throttle body and the IACV from the junkyard replaced both and idle RPMs were not at normal. When first turned on the engine rev'd to about 5500 rpms then dropped to 1000 but went up and...

    I got a Subframe Brace for a 94-01 Integra and I wanted to know if it would fit on my 97 Civic EX it is a coupe if that matters. I also have the lower control arms for the Integra that I believe will fit my Civic Thanks for all the help!

    I have a 99 dx auto sedan with the stock d16y7 and trans. I figured since I'm rebuilding the motor I may as well get a little more pep and throw a y8 head and intake mani on my old block. Will I have any issues just plugging the y8 p2p ecu in and running wires for vtec or will I need to get the...

    So I bought a sedan that has an auto trans Y8 in it, once it gets to operating temp, it begins to do a 200 rpm idle jump back n forth. Very irritating. Now I've seen people discuss deleting the IACV lines but I dont think that'll fix it. Should I just replace the IACV itself and the...

    Hello everyone, I have a 1997 Honda Del Sol Si with the d16y8 from the factory. It currently has an automatic trans but I already have the 5 speed, clutch, pedals, shift linkage, and everything ready to swap when I have the time to work on it. I plan on turbocharging it very soon after I put...

    Hi Everyone this is a help thread I suppose. Long Story short, my brother's 98 Civic lost compression on a cylinder in his d16y7. He got a 99/00 EX engine and ecu, and I told him I could swap it for him as I thought he got a obda engine, but that was not the case. Here are the main questions I...

    Hello, So about a month ago I put a turbo on my d16y8. Prior to this, I never really had any issues. After putting the turbo in, I got walbro 255 fuel pump, some off brand 550cc injectors and a p72 chipped ecu. When I first tried to start the car it started just fine. As the days followed the...

    Hello, I bought my 5 spd Ej8, d16y8 coupe about six months ago. I’m considering NOS seeing as I have access to a bottle. Is there a reliable way to have fun in a 1.6 l? I would go k swap or f/I but it’s pretty expensive. I’m aware nos is expensive by the bottle but has anyone else ran it in...

    Hi all, I’m new to owning a Honda and all the bits and pieces that come with it. I am running a stock D16Y4 and while it’s good fun I want something a little more powerful but I want to keep the D-Series motor I’ve had 10+ people telling me “just b-series swap it” but I like the d-series (hence...

    Ever since I installed a walbro 255 I've had issues taking corners with a lower tank of gas. I can get a 200miles before having the issue. I can't take corners hard because the fuel sloshes around too much and bogs down until it settles. The car comes back to life until the next corner or decent...

    Hi guys, I just swapped d16y7 intake with the y8 intake manifold. However the car acceleration is slower after the swap and I can feel something is holding back the acceleration around 6000rpm. Is this something got to do with camshaft advancing and retarding. TDC and BDC is as per the marks by...

    Since high school I’ve always wanted a little Honda since most my friends had 90s era Hondas growing up. I’ve driven quite a few from ef with sohc vtec to a GSR dohc vtec. I had some extra cash and decided I wanted a little project car and found something for a great price. I picked up a 98...

    D16y7 with a y8 IM swap, mostly stock rebuild, MLS headgasket and arp studs(prep for turbo at later date) polished everything I could get a dremel bit on. Slightly upgraded clutch, lightweight flywheel, port and polished head. Sold to a customer dropping it in a classic Mini.
