    Hi, I have a d15z1 VX hatch civic and I want to do a d16z6 mini-me to it. I read online that with z1 block, z1 internals and z6 head, the compression will be too low because of the dish in the pistons. I wanted to know if I can take d15b2 rods and pistons to make that compression higher ? Or...

    The questions I have is will the p29 pistons clear the y8 head? I ran the math 29+134+84.5/2 gets me to 205.25. The b7 deck height is 207.45 leaves me with 2.2 Will that work with b7 rods and p29 pistons? Will I clear? B7 is 30.7mm and p29 is 29mm of compression height. Reference to compression...

    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...

    Hey everyone. Been doing some research and digging through the forums. But still have some questions that I feel I should ask directly. To help make my swap as smooth as possible. I have a 88 CRX that's had a JDM SOHC ZC swap done to it. I got a Y8 head and manifold from a local machine shop...

    I'm nearly finished with the mini me swap for my 99 dx auto sedan and was wondering if running the p2e ecu for a little while will hurt anything aside from not having vtec. Should I run the y7 injectors til I get the new ecu?

    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...

    1995 civic dx D15b7 with D16z6 head Chipped p28 Aem cam gear. I did the mini me swap about 5-6 months ago and since then I've had to readjust valve lash like 4 times. It seems like every couple of weeks rpms tend to break up at like 5500-6000. However it clears right up with a valve lash...

    I have a 90 civic dx, d15b2 dpfi, I’m doing a mini me swap with a y8 head and y7 injectors every where I look it says to wire injectors to ecu a1,3,5,7 ports and then to the resistor box but my car doesn’t have a resistor box nor a spot for it on my wire harness do I need to run a resistor box...

    I have a p28 ecu,d15b7 block with a y8 head, y8 cams, y8 cam gear, and z6 timing belt. I am a little confused with what I’m supposed to do with the cam gear timing. Do I align the marks with the the arrow on the plastic cover behind the gear or do I align it with that arrow and go half a tooth...

    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...

    i’ve heard that the jdm d15b is better for boost because of better r/s ratio. i’ve done some research on r/s ratios but i don’t quite understand it. would there be any advantages to building a d15b7 minime with vitaras for boost over a d16a6 vitara mini me, because of the rod ratio, and would...

    I'm working on a Dpfi to mpfi swap. I had everything on hand but the dizzy. I have an obd2 dizzy from a d16y7 I bought for another project a few years back. I plan on swapping a d16y8 head and converting to obd1 in a couple months so I don't want to spend any more money than I have to. Can I use...
