A visual for example. Most older Honda engines have the ID plate here:

 

It's a D15Z1 motor is what the guy tells me. If i swap only the motor it wouldn't make my milage drop to like 20mpg or anything would it??

Yeah man! MoPar rules. the 360's are pretty B.A. (aka 5.9) But I run something a lil bigger 440 hehe! My dad has a '68 Dart 505 Stroker. Sexy! I'm currently working on a '66 Plymouth Belvedere 2-door hardtop. She's gonna be a running thing

 

Whoa, hang on. I'd guess you're running a D15b2 engine currently. It has 92 HP.

D15z1 is a different story. It's the Civic VX engine, VTEC-E, made for high fuel economy through lean burning. Has roller rockers if I recall. It's a 90 HP engine.

Oh, side note. Pics of the Belvedere please.

 

Haha, alright. I'll just give you a link to my Car Domain page. My motor is indeed a D15B2
So this D15Z1 is a weaker motor than mine!? Lame. I need to start looking for something else then. I'm not so much looking to beef up this car. At all. I just want it to quick smoking. It would be nice to get some more power outta it tho.

My Belvedere isn't too appealing to those who like more rounded cars. She basically a box.

I loved looking at those pics. Lots of cancer that had to be cured. Good looking car!

Now, don't give up on the z1 yet. It's a minor HP difference and the fuel economy gains are great. You could probably squeeze a couple of HP out of it by adding an aftermarket header and a short ram intake. That would at least give you +2 or +3. And, no smoke.

 

A buddy of mine in Southern Nevada has a 440 in a Demon & races a Demon @ Las Vegas with a 5 something inch motor turning in the 9s.
Really a 400 built is faster than a 440. I drove a former cop car with a stock 400 to 145 mph back in the day with a certified speedo. Don't get me wrong the 440 is a fast motor but the hard core Mopar guys I know prefer the 400s over the 440s.

 

Here's my research for basic swaps.
You have a D15b2, weak, but not the weakest.
If you want some nice HP gains, convert to MPFI. That will get you somewhere in the 100 hp range.
With MPFI conversion complete, it opens up a door of swaps...
D16a6 is the Si motor of that generation. 105 hp, not bad. Direct swap if your car is wired for MPFI.
D16z6 is the Si motor from the 92-95 generation. Retain your stock mounts, wire for obd1, wire up vtec and a couple other sensors... good to go. 136 hp ish.
D16y8 is similar to the z6. I consider it a small step up... little more complicated.

You could always look into getting a ZC motor, either DOHC or SOHC. hmotorsonline.com has a motor mall to look at. Stay D series if you're on a tight budget.

 

The only reason your buddies prefer the 400 is because it had the biggest factory bore. 4.350 i think. And you can slam a stroker crank in it and acheive 520 cubes. It's pretty B.A. But to my knowledge police cars DID NOT come with 400's. 383's OR 440's. He could have put the 400 in it. Or they might have made them. But hey, as long as it is MoPar i love it! <3 A Demon is an A-body, wickedly small and light. A huge fat 440 in a tiny lil a-body is a rocket! My dad has a '68 Dart with a 505 stroker in it rocket baby.

Thanks Hobo :3 i've had her for 6 years and i'm getting ready now to start building my 440. I think that the '66-'67 years were the best for Plymouth and Dodge. I absolutly love those long lines! A '67 Dodge corronet is beautiful! Coke-bottle type quarters <3 The thing is, this guy wants like 600(final price) for the entire car.... But 1k for JUST the motor. I dnt have that much to spend on my Honda. I'm thinking i might find myself pulling a junk-yard motor and going through it to check everything. Do you think that would be cheaper? I can port my heads and all that for better flow. But I'm not looking at spending a lot of money for power. If i was, then the first words outta my mouth would be SEQUENTIAL TURBOS

To Zerojett: Now do I have to swap my intake manifold if I switch to a lil bit bigger motor? Such a a 1.6 of the same generation. I really dnt wanna change my wiring harness. If i can help it. At the moment I cnt afford to have my car down for more than 2 days at the most. Could I swap a D16a6 into my car BUT leave my factory DPFI? Or would that hurt my motor horrably?

 

No it shouldn't damage anything to put DPFI onto a 1.6. Just slower and probably not quite the mileage that the matching MPFI / OBD1 system would achieve. Apparently they always used the same fuel maps for 1.5 and 1.6 anyway.

 

MPFI swap is a simple concept... if you want to do it, read this page a couple of times to understand it. http://www.fourthgenhatch.net/mpfi.html
you only really have to run 4 more wires into the engine bay, and extend a couple more, so I hear. I haven't done it quite yet, but it is something I will need to do eventually.
You will definitely notice a huge difference in throttle response when/if you do it though.

You know, my uncle is into Mopar type building last I checked. He was working on a Chrysler Daytona I believe. He drags it... took me for a ride one day, man, that was a lot of torque. I know nothing about it though, I don't even really know what Mopar is... I always assumed it was basically the domestic Mugen?
