Help!!!

Ok so i spun a rod bearing in my d16a6 so im swapping it with a d16a1 are all the mounts and plugs the same and how much more hp will i get ?

The D16A1 won't fit in there very easily - it's actually a different series motor. The motor mounts are way different. You'd be better off fixing the A6 or finding another block than trying to fabricate new mounts and stuff for the A1.

But its possible? and does the a1 have more hp than the a6? And what will i all need?

I don't know of anybody that has actually done this. You'll gain like 4hp and 1 less torque for all the work you'll put in to it, it's not worth it. I've heard of people trying, but gave up because of the amount of fabrication required. You'd do way better dropping a z6 or a zc or another a6. The ZC is over 130hp - which would gain you about 20hp, the z6 is 125hp which is a 15hp gain - way more than the A1 and they are drop in and plug in practically - no fabrication.

So whats the best engine to drop in it without having to mess with the mounts and plugs and that will give me the most hp with dual cams?

And how do i tell if a engine is a zc or not?

Will a crankshaft from a d16a1 fit in a d16a6?

The ZC is the only drop in motor that will drop in without any modification. "ZC" is the actual engine code - you usually have to import them or find somebody that has one - I don't think that they were ever released in any US cars.

The crankshafts are different I believe as well. The second best motor to drop in is the D16z6, but it will require a little rewiring. The ZC isn't as easy to work on because it's kinda the ugly headed step child of the d series motors. The z6 is going to have more support for aftermarket and upgradable parts.

Can i put a twin cam from a d16a1 on a d16z6?

Nope, the head bolt patterns are different. Even the ZC head won't bolt to a single cam block.

Dont get in the mindset that SOHC isn't worth anything, they can put out some power.

The A1 is out of the old integras, its a common swap with the 1g Crx because its one of the only engines that will drop right in those chassis.

Z6 is possible to drop in without rewiring, just use your current distributor and ECU. It performs better if you convert to OBD1 and use its distributor and ECU, but its not necessary.

As he mentioned, the z6 will have more support than the ZC. If you were wanting to build an all-motor engine, the pistons out of the A1 are actually perfect for the z6, will bump the compression up to 11:1-12:1 depending on a couple variables. Z6 is also a good turbo engine, I hear Vitara(i believe) pistons are great for turbo setups, will lower the compression from stock to allow more boost.

Niether engine, z6 or zc, will require different mounts, wiring is just variable. I would suggest switching to OBD1 at some point, if your going to build its almost necessary so you can tune it.

So i swapped my d16a6 with a z6 and i sit in my car to smoke before we tried starting it and i turned the key to on and the check engine light flickers and ticks or buzzes and there is this wire in the engine that looks like it would go in the battery but cant find where it goes maybe the problem idk.....

Not enough info man. There are a lot of wires under the hood. I don't know what all you swapped over, I don't know how I should tell you to check the Check Engine light, etc.,

ok so i swapped my a6 with a z6 but used the a6 head (non-vtec) and stuck with the same ecu from the a6 when i started it today it runs but idle at a little over 2000rpms then after 30 secs or so i jus rev all the way up do i need the ecu from the z6 and if so will it plug right in to my a6 wireing dont have a lot of money so im trying to fix this problem cheaply jus so i can get it out of the garage and does the head from the a6 make a different in it running like shit let me know thanks.....

Read my first post.

Not sure why you swapped the a6 head over to the Z6 block, you just created more work than you needed to.

Your problem sounds like either a timing issue or some other issue that is keeping the ECU in Limp mode. Pull the passenger carpet back and count the flashes.

Z6 ecu will not just plug and play, you would have to convert to OBD1. You can use the a6 ecu with the a6 distributor even with the z6 head. It won't engage vtec unless you hook the Vtec solenoid to a switch yourself, but the engine still wont have the correct maps so it won't run as well as it should, but it will still run well enough.

Again, read my first post.

And try to add some punctuation, makes it hard to follow without it.

Ok yea i didnt have the vtec head for the z6 so i jus stuck the a6 on. and what do i need to do to put a p28 in my car how hard would it be to swap the wire harness?

Thats what you need. You never swap engine harnesses, you just modify the one that came with your car. If you did swap your harness when you put in the z6, swap it back.

You don't need to run the p28 if your not running the z6 head and distributor. The bottom end is basically the same block, its the heads that make the difference between the two engines.

Check your codes and double check your timing, make sure you have it right.

can you explain to me how to modify it so i can put the p28 in cause i wanna put it in with `the vtec head

an another question is there a ecu thats vtec that will jus plug up with the same plug used for my ps9???

Dude, read what I have already posted a couple times, I can't make it any clearer than that.

Your stock PCM plugs will not plug into the P28, it requires a conversion harness: OBD0 to OBD1. Get the conversion harness, PCM, Distributor and add a few wires. Boomslang comes with good instructions to let you know what wires to add.

ok so there are 3 hoses on my pgm-fi in like the middle of the intake i cant figure out where the middle one goes anyone? please this is the only thing is the only thing thats making my car not run...
