Few general questions about gas engines

I have a few questions about gas (or diesel) engines.

How many moving parts do you think a modern engine has?
How much does a typical, smallish (honda or toyota sized 2L) engine weigh?
In general, how involved is the engine removal process?

A four cylinder probably weighs a few hundred pounds, depending on if it's an iron or aluminum block, and how much crap is bolted to it. Add at least a hundred or so more if the transmission is still hanging off of it.

With all the cruft newer cars have, the removal process is probably somewhat complex. Of course, removing it is easier than reattaching everything.

I believe my Civic's D16Y8 w/ tranny weighs around 400 lbs. I've swapped a D16Y7 before (an economy version of the same block) and it was quite difficult. You really need someone who knows what they're doing before attempting an engine swap.

The engine weighs about 170 lbs for a typical D series which honda has used since the late 80's all the way to 2000.

The transmission on a typical D series is 110 lbs (I know because I had to ship one lol).

They are both cast aluminum so they are pretty light. One guy and a hand truck and its no problem to move around.

Here is a pic of the engine we took out of my brothers car for a swap. Had to bring the old one back home so it rode shotgun in my car (I removed the passenger seat).



As far as the engine removal process its really not that hard. Honda's have such a large following every single problem you can encounter has been solved already. There is really no guess work involved anymore and you don't even have to do any fabrication anymore as companies release all the parts need to put any honda engine in any other honda (or even acura) chassis.

Are you interested in swapping your car?

1. You have many moving parts.
2. Somewhere around 200-400lbs i would say.
3. You need to remove all mounts, remove all lines going to engine, drain coolant and oil, and remove hood.

^^ I disagree. Please show me a company that fabricates mounts for 1986-1989 Honda Accords. No company makes them, there for all mounts have to be custom for these Accords.

Well lets put it this way. From 1988 to present everything is very very easy. When you get into the older cars that still have carbs it gets trickier because not many people own them and there not much of a demand.

Anyway im assuming the car has the stock A20 engine in it?

Since its not as common you can get mounts they will just be more expensive.

Racetek Engineering makes them to swap a B16a in along with the wire harness needed.

here is a pic of it done



Also check out

www.3geez.com

Its all about the 3rd gen accord. But yes it is much more involved then the newer hondas.

Although it is probably not worth your time/money but thats up to you.

Also I have heard you can just swap a b16 head on and get some gains but im not to sure as im not familiar with the a series engines.

if you're ever hoisting an all steel 454 pontiac powerplant and trans out of a donor car and you hear something snap - run away.

just take my word on this.

An engine swap is a piece of cake!

Remove battery!
Drain engine of coolant
Disconnect all wires and harnesses
Disconnect fuel lines
Connect engine hoist to engine and pump the lever enough to have a little lift
Remove the bellhousing bolts holding the engine and tranny together
Remove motor mounts
Remove exhaust downpipe from manifold
Lift engine out of compartment.

Piece of cake!

It took me over a day to get a motor out of an old rusty jeep. I eventually had to give a buddy of mine that owns a welding shop a call to come cut off some bolts using an arc welder. They were the hard to get to bellhousing bolts. Small motors from small cars are easy as hell though

The junk yard I like has a rule, they will never charge more than 100 bucks for any engine. Engines tend to only be valuble if they are very rare and desirable, or if they are part of a functioning car.

In other words, not really.

At old Volkswagen shows, I think it's fairly common to have Beetle engine swap contests. The good ones can do it in about 20 minutes, I think. Of course, it's just four bolts or so, the fuel line, and some electrical before you can jack up the back of the car and drop the engine out.

Did you mean for YOU to buy a used engine? I bought a 4.0L inline 6 cyl. for me old Jeep with 50k miles for about $600 at a junk yard. Those little motors should be easy to find but beware.....little ******** ricers tend to beat the crap out of civics and whatnot.

Yeah, my brother and I removed a 4 cylinder engine out of a Mazada 626 in an hour, but we used a sawz-all just has much as any wrench...

Yep, beware of engines found in cars with huge spoilers or ground effects int eh junkyard. Those are signs of a possible "ricer", which usually means that engine got ran hard.

Best engines IMO come out of the cars that looked like someone's grandmother drove them....yes theengine amy need a rebuild something awful, but at least you know that the block may not have some unnoticed damage from some jacktard throwing NOS on it (my NOS rant is pretty long...basically I think only one percent of the people that talk about it should use it, the rest probably will usually end up killing their engine within the year).

It usually doesn't hurt to separate it from the transmission/transaxle and exhaust system too Also, things like the air intake plumbing, battery tray, radiator, and manifolds can often get in the way of easy removal. Depending on the car, you might be in for a lot of work.

I do believe my VW 1.6L diesel when mated to the transmission is about 350 pounds wet. (Iron block, too.)

I know the tranny itself is about 75 pounds wet.

On these, diesel swaps are rather easy... coolant lines, fuel lines, and two wires for the engine itself.

As for moving parts, depends on the engine.

Crankshaft, connecting rods, pistons, valves (at least 2 per cylinder, as many as 5 per cylinder,) camshafts (at least one, as many as four for a V engine,) possibly rocker arms (on OHV engines or engines with one camshaft and 4+ valves per cylinder,) possibly pushrods, and some more stuff.
