Hey guys, Ive ran into a problem with the nuts being tightened on the manifold. Some of the nuts seem to not fit all the way down onto the stud, since there are clearance issues. These are the stock d15b intake manifold nuts, which fit good on the studs, but dont fit with the intake. I was...

Hey guys, I wanted to ask for some help, but let me update you guys on whats happening: I have a 97 Integra GSR with a d15b, P2A-4 head, and a P4A transmission. Ive taken off the head, and taken out the block and trans. Bought a used d16z6 head, which I measured with a straight edge and files...

looking for the best possible bottom end bearings for a d16z6 was looking for a way to go roller bearings instead of normal sleeve garbage? Been through 3 bottom ends now went through 2 in one engine and blew a hole through the side of the block and have another on just knocking and thinking...

Hey everyone, I’ve used HTS to street tune my d16z6 swapped UKDM ED2 sedan. In order to maintain my cable clutch, I’ve used the cars original transmission which was originally mated to a d14a1. This is causing some issues with the gear readout to be wrong, which I think is causing the tip in...

Hey all, I have a really strange issue going on with my OBD1 Civic. When driving downhill, the CEL comes on, a few seconds later theres a pop from the exhaust and the CEL goes out again. While the CEL is on I can’t accelerate, the engine sounds like its suffocating. The moment the light goes...

Hey everyone, Long time reader, first time poster so go easy on me. I have a 91 civic sedan. I'm in the UK so it was originally a 1.4 dual carb. After this I swapped in a JDM D15b, since then I have gone to a D16z6. Before going into depth I will explain my setup. Its a D16z6 using the D16z6...

Are they compatible?

I bought a z6 head from someone and upon disassembly there are cracks around the bolt holes for 2 of 5 valve cover bolts. The cracks are less than 1cm long. My question is would the rocker assembly still be safe to use in a high comp mini me build. Cheers Zingle

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...

Hi all, new user here and completely new to Hondas, although I've done my share of wrenching on many different cars. I've been reading through this forum for a few days but I have a sort of specific situation so I was hoping for some help. I just picked up a 1995 Civic EX for a grand and my...

are there any parts of the z6/y8 heads that aren’t interchangeable? cams (with matching gear of course), springs, valves, etc. ik some of this has been covered already but i’ve never found a definitive answer. thanks

I have a ongoing issue I hope someone can help with. Built Vitara Z6. I'm having a timing issue. So I line up the crank with the white single slash and the corresponding marks on the cam gear. So in theory this should be correct. But I'm still only at 11* of timing. Even with the dizzy maxed I...

Hi guys, I'm a new member to D-series and I need help with suggestions or recommendations on parts I've already picked out for a future D16Z6 build. I have never built a car before and plan to build my first Honda very soon. Of course all of my parts are from eBay and I need people who build...

Hello everyone, I have done my rebuild of the d16z6 engine that sits in my civic wagon. I did the proper break-in period. But, what I thought is that I had CEL1 code of o2 sensor, and that my tuner will just turn that off. I got to the dyno yesterday, did the pulls, and the car would just...

Hey guys its been awhile! My previous post is here if you're interested in the build. Just kidding, it wont let me post links. I'll PM you if you want to see it. I did get Skunk2 Pro 1's all around as well as rear disc conversion. Not that it has anything to do with this post. Sooooo, my...

Hey guys, I've been doing some digging and I'd like to pick the brains of people more knowledgeable than myself about real world numbers. My build will be running the following: Complete D16Z6 CP 9:1 compression forged pistons 75.5mm Eagle rods ARP head studs ACL bearings (I think it was?)...

Hello Im new so I thought id show off my build so far. A little Background of the car up to this point. I bought the car about 4-5 years ago in Los Angeles in a mobile home park which is sat under a tarp for god knows how long. She is my daily driver and soon to take to the track when i get...
