Does anyone know how long these engines are? A craigslist ad has me pondering a potential swap into my 2002. Just wondering how much space is needed from the radiator to the firewall for these.
A quick googling just tells me the bore and stroke dimensions, but not what I need.
Vortec is not LSx. The original Vortec is a regular old Chebby 350 with cool heads. The new Vortecs are LS-based iron-block truck motors (some did have alloy blocks like their LSx car brethren). New Vortec = Hotness, old Vortec = meh.
You're referring to the inline 5 cylinder, right? If I remember tomorrow, I'll measure some over all dimensions on my dad's H3.
Yes the 5 cylinder is what I'm asking about. DOHC 3.5L 220 hp 225 ft-lbs from the Colorado/Canyon/H3.

vortec=truck engine
just like back in the olden days when... ---turbo fire= small block V8 ---turbo jet= big block ---turbo thrift= 250 inline 6 cylinder ---hi-thrift= 194 inline 6 cylinder ---i forget what the 4 cylinders in Novas were called..
Doesn't the 5cyl. have a reputation for premature self destruction?
If that is the case then maybe I'll look elsewhere, The engine has under 50k on it, no idea of maintenance history. If the 5 cylinders have a bad rep, what about the 4 cylinders?

Not that I'm aware of.
Known as an Atlas, they're awesome motors, and very stout.
wait wait wait, this 5 cyl gm motor is going in what car?? 2002 can refer to a few different vehicles
I thought someone built a turbo one of those a few years ago though I can not find anything about it right now.
Just use an Audi 5cyl 20v turbo. 
They just sound so sinister....
Found it:
We built this complete turbo system last fall for my 04 3.5 Colorado Crew Cab 2WD.
This set up made 387 RWH and 400 RWT at 15lbs of boost.
We made this power with 93 octane and 25% 110 race gas, through the stock exhaust and the one rear cat
We are de-modding my truck and putting it back to stock to sell it.
This set up have will make 6 lbs on boost on the foot brake, can be adjusted from 6 - 15 lbs
This system inlcluded everthing to bolt this system on a make big power.
A Real Garret 54mm Turbo with a T-3 .70 A/R ex Front mount Air to Air intercooler All steel 2 1/2 intercooler piping with hoses and clamps High flow cleanable air cleaner Fuel rail with return style with 5 50lb Delphi Injectors, harness ready to plug into main wiring Custom built Turbo Manifold 38mm WasteGate Complete intake manifold modified for Turbo system
Down pipe built to bolt directly to the stock Colorado Exhaust (No cutting or mods needed)
Also available Copy of our Custom Speed Density Tune.
Only a couple mods needed on your truck You will need to put 90 deggree connectors on the Heater hoses You will need to agjust the location for the Trans Dipstick You will need a GM 2 bar map sensor if you used our tune.
I have over $4500 invested in parts and labor in this system,
Asking $2400 or best offer
PM if interested

This is just in the thinking/dreaming stage right now. I am talking about a BMW 2002. Just saw an ad on (where else) craigslist selling a 5 cylinder Atlas engine from a Colorado and wondered if it would fit. It would be more power and funny. I am currently gathering the parts to megasquirt the M10 that's in there, but I don't know the history of the engine. Figured why not make it even more difficult and stick something else in there entirely. I would hate to spend the time and money to get the current engine up and running on megasquirt to find out it needs a rebuild anyway.
Better choice: Duratec 2.3 out of a late model ranger. much lighter and more compact. Decent power, with much more available with simple mods. easily avaialble with 5-speed. I have no problem with Atlas engines - especially the 4.2 6 cylinder. The 5 is too bulky and heavy for a 2002 IMO.
I like the idea of using the 2.3 duratec, but it is rated for a lot less power and there isn't one for sale on my local craigslist.
How similar is the ford engine to the mazda MZR 2.3 and the 2.0? Wondering about after market support. Seems like NC Miatas and Foci would have more available stuff than H3's.
I guess I can just go down to the local dealers and pretend to want to buy a ranger or a colorado and take a good look at both engines.
Maybe I'll just be on the lookout for a wrecked NC miata....afterall that is always the answer.
The early 5cly had head trouble of some sort. Poke around some Colorado forums for better details. The later 3.7 engines and all the 4 cly's are ok.

I have an NC longblock I'll let go dirt cheap.

Slow 
From what I've read on HybridZ, the Atlas is roughly 30" from the bottom of the crank pully to the top of the head. It is a TALL engine, and very, very likely will not fit under the hood of the 2002. It won't fit under the hood of a Z either without being dry sumped, moved back severely/turning it into a stressed chassis member/huge hood bulge.
Great engine...just too bloody tall.
So I measured my dads H3 3500. From bottom of the oil pan to the top of the valve cover was about 28". From the bellhousing to the front of the head (which hangs out past most of the belt driven accessories) was about 25". The accessories were about 26" wide on the front of the engine but just the block/head was about 14" wide. I hope that helps.
Thanks for those measurements. That's quite a bit larger than the M10 that's in there now in all three directions. I'm guessing the 4 cylinder atlas engine has the same width and height, just a little shorter front to back. I think that is too big for the space I have. I'll go look at a ranger or NC miata and see what they look like.
A while ago there was a glut of 2.3 Duratecs. A friend bought two brand-new long blocks with manifolds for $600 each off e-bay. The thing about them is that they're way light. My friend could cary one of the motors (admitedly he's a strong guy). Also they take mods real well. You're cams, headers and a megasquirt away from 200+ HP. The Miata motor takes boost better, but is significantly heavier and doesn't respond as well to NA mods..
personally i say keep the m10 and i like the idea of megasquirt, but why not beef up the bottom end while youre at it? maybe even rework the head, and check everything to make sure it works. m10 is just a cool little motor, build a sweet example. you could also drop an s14 and have an ///m2 >:)
I like the M10 as well. The problem is that this car was bought at near challenge prices and while being a nice 10 footer, it's got some issues. I've got it where it runs reliably and well - way better than when I got it last summer. It now turns, brakes, keeps the oil inside the engine, starts easily, idles well, etc.
I'm not deadset on performing any swap on the car - it was just an idea that came to me from cruising craigslist. My E30 318 intake manifold, injectors, fuel rail, and fuel pressure regulator should arrive on my front porch today. That will just leave me a megasquirt box, a new fuel pump, a throttle body, a fabricated throttle linkage, a new coolant neck, and a coolant bypass pipe away from the next project. I've already converted it over to megajolt and that was a big improvement. Not too worried about increased performance - been using the car as my daily driver, although a 5 speed would be nice in place of the 4 speed. I figure all told going for an all out engine swap that would piss off a lot of BMW purists would cost me about the same amount of $.

Valve seats. It usually happened eaerly, and was covered under warranty.
