Please help - need KL-ZE info

[Baja_Wes]

Please help me with info, I am desperate.<P>I own a pretty wild vw (see my website). It currently has a reasonably powerful engine, and goes well (low 16's 1/4 mile). The only thing is I want air/con, and heating. To adapt both to the current engine would be quite difficult, and it would be somewhat easier and more benefit would be gained by jamming a jap import engine in it. <P>Since the standard engine is a flat 4, I need a short engine. A lot of people have put wrx engines in vw's, but I don't like wrx'es and the sump hangs too low for offroading. <BR>Inline 4's are probably a bit long and would look funny in the engine bay, lots of room either side. So I thought a nice small capacity v6 would be good. Like the 2.5lt 2vz-fe camry motor, or the KL-ZE 2.5L mazda motor. <P>Does anyone have any info on this motor? I need to know the weight of it, which will be difficult to find. I also need to know all the dimensions and stuff. Does anyone have any good links to info on this engine? Is this a good engine or should I avoid it? On paper it seems good. Is it all alloy, or does it have a cast iron block.<P>I asked these questions on toyota forums about the toyota engine, and got no useful responses. Please help me guys. A 200HP KL-ZE motor should give me high 13s 1/4 mile, and good low down performance for lugging about offroad.<P> <p>[ March 26, 2002: Message edited by: Baja_Wes ]

Check some of the links in my sig.<P>It's a pretty small motor externally. Weighs around 380# for the complete assembly.

[Baja_Wes]

how sure are you about that weight? My vw engine is only 210lbs. Does the mazda engine have a cast iron block or something? <P>My engine and gearbox would be less than 380lbs.

[Baja_Wes]

I looked at some of the links, they are very good, thanks a lot. I am still after the weight though. The link emphasises light-weight, but never says what it is.<P>Oh, and I figured out it is an alloy block. Center split crank case like a vw?

[Baja_Wes]

horizontally split, not vertically split.<P>I found a good page for old car engine weights. <A HREF="http://www.aviator.cc/weights2.txt" TARGET=_blank>http://www.aviator.cc/weights2.txt</A> <P>It says old chev and buick engines are 350lb. A rover 3.5 V8 is 318lb. Surely the mazda engine is less than 300lb.

You ask for info and then doubt it. <BR> <P>The Mazda V-6 is heavier than you might think since it is a DOHC. Veedub engines are lighter since they are air cooled, no water pump, cooling jackets, etc. But you should know that right?<P>Cast iron Chevy/Buick small blocks weigh about 550 lbs.<BR>The Olds/Buick V-8 from the early 60's you speak of is the all aluminum 215 in. and is the basis of the Rover 3.5/3.9/4.0/4.2/4.6L engines. This V-8 weighs about 340 lbs (uses a cam installed in the "V" but physically the same size as a SBC) and adapters are available for bolting it to a VW. If you want more info on this engine, then email me to get this non Mazda info off this board. jcork@tcainternet.com<p>[ March 26, 2002: Message edited by: pelado ]

David, you link to pictures doesn't seem to work.<P>I am legally limited to 2.5L as the biggest engine I can put in my car. <P>So a 60's 3.5L v8 weighs 340lbs, but a recent technology designed to be lightweight 2.5L v6 weighs 380lbs? It just seems a bit heavy. What accessories does that include on the engine?

[Baja_Wes]

I spoken to two jap engine importers. One says 265lbs just the engine, and the other says 365lbs engine and gearbox. I think they are both guessing.

This morning I just lifted a Mazda 2.5 V6 engine from a van and put it into my garage. It's very heawy. Me and my friend could not hold it in air for more than a second or two. I estimate it at around 150 - 170 kg (330 - 380 lbs).<BR>The engine was complete but without the tranny and flywheel/clutch.<BR>So add another 60 kg (130 lbs) for this.<BR>(i have a spare tranny lying around and know how much it weights) <P>Now I have a 2.5 KL03 that needs new head gaskets an then we go. MX-3 GSR.

[Baja_Wes]

ok, so you and a friend can only hold it for a second or two. Unless your huge, I don't think it'd be any more than 300lbs. <P>A beetle engine is 205lbs, and me and a friend can hold it for a minute, but you'll be pretty sore afterwards. A type 4 vw engine is 250lbs, and we can only hold it for a second or two. They are quite heavy. <P>So it sounds like a 2.5L V6 ain't much heavier than a type 4 vw (unless your huge). <P>I don't suppose you feel like getting two bathroom scales, putting a big peice of wood between the two, put the v6 on the wood and weigh it?

[David Coleman]

Well, I may not have the figures you want for the engine, but I KNOW the tranny weighs 80-90#.

[pelado]

Maybe you should try for a late model Subaru engine swap. It should weigh about the same as a waterboxer while making more HP. And it weighs exactly 250 pounds.

[vseved]

First I must go out and buy two bathroom scales It's a heavy beast believe me. <P>The V6 version of MX-3 is something like 150 lbs heavier than the 1.6 I4 version. <BR>Most of the weight difference is in the engine.<P>I trust my judgment about the weight. the low 330 lbs estimation must be very close.

[Baja_Wes]

The majority of the guys on the probetalk forum seem to think it is about 250lbs. A few guys there have lifted it no probs, and even put it in the hatch of their probe. One guy has a shipping order receipt that says 250lbs. <P>If I go ahead and buy one, I will weigh it and we'll all know once and for all.

[Baja_Wes]

Well I finally found a good cheap Jap MX6 half cut, which I have purchased. It will be a little while before I get the engine out by itself, but when I do I will tell you guys how much it weighs. <P>I am keeping a diary of the transplant too.<BR> <A HREF="http://offroadvw.net/bajawes/linktoV6.htm" TARGET=_blank>http://offroadvw.net/bajawes/linktoV6.htm</A>
