need some clarification

[KhanDST]

im looking at a 92 lx and i wanna kno more about swapping engines or putting in mini me's, wat is the best and cheapest way to go

Best and cheap don't go together. Figure out a budget, how much power you're looking for, and how much power you're going to want down the road. Say you did a mini-me swap and did bolt-ons (intake, header, exhaust). If you decide you want 250whp down the road, you've wasted $ on doing the bolt-ons at least; if not the cost of doing the mini-me as well. Take your time and do a ton of research before you do anything... meaning a lot of searching.

The D15B7 is a very weak motor, one of the weakest blocks honda made. I won't waste my time mini-me'ing that motor...if you want a sohc vtec motor, swap it out for a D16Z6 motor ecu instead of mini-meing the D15B7, it's a little stronger of a block (92-95 EX and Si hatch motor, 93-97 Del Sol Si motor).

How the hell could you ever say that? Maybe if you're talking about racing it or doing some heavy modifications, but not as a stock engine. The D-series motors (for the most part) and bullet proof, and one of the greatest inventions ever made. What other motors could you be driving, pull over, open the oil pan bolt and have 1 drop of oil come out; and still be able to drive it a few miles without any problems? Or how many other motors could you run up 400,000+ miles on and still have it run like it's the first day it was made?

It's a fact that the D15B7 is a weak motor in stock form. Have you ever seen the size of the rods in a B7. They look like spaghetti noodles. Try to get any power out of those things in stock form and you're almost guaranteed to break something. The D15B7 isn't a performance motor, and it's not bullet proof. It may seem bullet proof but that's because it has no horsepower to really cause any major wear on it. Reason why they get great MPG and last a long time. Same goes for all Ds really.

You are grossly misinformed. Do re-search and learn the facts. First, not all D-series blocks, rods, etc are created eqaul. The D15B7 is one of the weakest motors honda made ever. The rods thinner than the other D-series motors, and the rods and rod bearings are very weak. They can not handle much power of abuse AT ALL before they snap. Also, D-series themselves can't handle much detination or pre-igntion before they blow (compared to the B-series) but with the D15B7 is weaker than the other D's. Plugs even one color range too hot will cause the D to pre-ignite and the motor to tear itself up in a matter or afew hundred miles sometimes. As a result, it is VERY EASY for a dishonest mechnic to screw a D. Plenty of D-series leak oil, blow head gaskets, etc...heck...I know members of this site who's D-series went to h*ll. Still,if you care for it and keep the motor sotck it can last a long time. Even modding can be done within reason to most d's...but the D15B7?? Forget ti...abuse it, drive it hard, add much power...forget it...snapped rods and ruined block. This guy wants to mini-me the motor, and then he'll want a lil more power here and there...it's a waste on a D15B7. It's a weak motor, block wise...the weakest motor honda made...He's better off swapping in a D16Z6 if he wants SOHC D power. That can handle more power than a D15B7, the rods aren't quiewt as thin or brittle, and the rod bearings are a little better...and that swap won't break the bank...but mini-me on a D15B7...heck...any mods on a D15B7...a waste of money...period.

I think you should read my second sentence...
"Maybe if you're talking about racing it or doing some heavy modifications, but not as a stock engine."
I also ment that as driving the engine hard or beating on it. And all the other problems you listed can happen to any engine made by any company. I'm not saying the engine can't be broken or that it's the best engine made (the d15b7 is particular). But compared to most engines out there, the d15b7 can last a hell of a lot longer. And it's also how you take care of the engine. As an example, I'll compare my CX engine (8-valve) to my parents Dodge Caravan. I just turned over 180,000 miles and my car is running stronger than when I got it a year and a half ago at 168,000 miles. My parents Caravan on the other hand, the engine seized at around 175,000 miles. Now my parents always take care of their vehicles, even better than I take care of mine. So unless my engine seizes or otherwise breaks sometime soon, I still stick by the fact that any D-series engine is better than most out there. And my crappy CX engine is far weaker than the DX/LX engine.

I've got a D15B7. I have no desire to put even $1 into modifications into the engine. I had no idea that it was considered a weak engine. Plus at @ 220,000+ miles, I dought it could handle it. If I want speed, I jump on the CBR600. That's plenty of speed for me. I will say that I take care of my 4-banger like it's worth $1,000,000. I do treat it like crap sometimes. I tow a trailer when loaded weighs about 1/2 a ton. I call it, my 40 MPG 1/2 ton 4-banger. On a straight road no problem...hills, well you could only imagine.

Your first 2 sentences summed up yourpoint in the first post. You said...

You said racing or heavy modification...well...a mini-me conversion IS a decent mod HP wise, adding a good 15hp+ to the motor. Now, this motor STILL has the SAME weak ass thin rods. You said "The D-series motors (for the most part) and bullet proof, and one of the greatest inventions ever made."

Well, as GScivic7 as I pointed out, the B7 has spaghetti noodles thin rods and weak rod bearing, it is FAR from bulletproof. Pretty much ANY modding, mini-me included is bad, as the motor can't handle it. The thread starter asked about a Mini-me on a D15B7...so I pointed out the facts, it's a WEAK motor with THIN rods and WEAK bearings.

How could I say that you asked? Because it's the truth, and he wanted to know about a mini-me conversion on a D15B7...which IS modifying it!! That makes this a VERY relevant point. As GScivic7 said, they may SEEM bulletproff but it's an illusion. They only seem that way since there is a fairly low redline which will lighten the wear and there is no horsepower to cause wear on it. As he said, this is why you get great MPG and they last for a long time, there is no power and low a rpm redline, both which me minimal wear stock but give great MPG and help it last a long time. However, try to do any hard driving, or much of ANY modding, a mini-me swap, I/H/E...and you'll find these motors are FAR from bulletproof. You said the D-series is bulletproof. If you want bulletproof...get a 6-bolt 4G63, the D-series is NOT bulletproof, especially the D15B7.

[CivicSpoon]

Why did I even bother You're absolutely right on your points. Too bad you can't read what I wrote and understand what I'm saying. If you want to understand, read what I wrote word for word; and only what I wrote. And also look at the 1 sentence that I quoted from your original post. I made a point to only include that single line in the quote. I made absolutely no mention of a mini-me swap. Sorry I guess I just assumed you understood that when I said "Maybe if you're talking about racing it or doing some heavy modifications, but not as a stock engine." that it included any modification (bolt-ons, aftermarket internals, head swaps, FI, etc). But oh well, I'm done with this conversation if you're going to be opinionated and have selective reading.

My D15B7 (Dead now)



Doing too much of this



Caused this



and now have this



I baby it now. I need my car running

[polacek]

sageuvagony, what did you upgrade to? Funny to see an engine exactly as mine. I put in a CAI because I added a small compressor and two air horns 18 inches long thus I needed the space where the intake "box" was housed
