Two Heads better than 1?

What was mitsu thinking when they created a small capacity v6?
I mean from the con side of things wouldnt it create more maintenance and complications?
If a single head inline 4 can produce just as much power then why a v6 head?

i guess it more interesting, its the Other solution to the problem.

Imagine if every fast car had a inline 4..... pretty boring??

power delivery is smoother in a v6?

I can't quite work out what the purpose of your message was.

If you're suggesting there's problems and issues with the FTO's engine I'm sure we'd all love to know, but history seems to show that the 6A12 is a very reliable engine, has very few problems and doesn't need any extra maintenance.

Was there a 2L 4cyl that produced as much power as the 6A12 does, 10 years ago?

Just for discussion sake is what my message is about. lol

no doubt the 6a12 is reliable as. even I know that.
But say when the time comes to redo the head. things like two gaskets.
Quad cams . More moving parts. etc.
Surely more parts and more moving parts mean more money involved in maintenance and repairs?

A simple Inline 4 that makes similar power technically should be cheaper as less parts to replace? More room in engine bay? less labour involved?

Honda boys change their spark plugs in two jiffies and its all good. We have to take off plenum and put platinum in so it last longer.
yes we do it once but it still has to be done.
Two headers aswell. More gaskets again.

yes i wonder that my self, why use a V6 when a 4 pot does the job? eg integras preludes etc.

but from what ive HEARD, they are more harsher and not as smooth.

but i would like more space in my engine bay and it would be more simpler. but i guess its kinda fun when you tell your friends you have a "vueeeee sixx maaate!"

hahaha lol
Gotta admit though.. for a v6 FWD east west setup the FTO beautifully designed layout in the engine bay makes the most of the space available. Its got a lot of room for what it is. You should check out some of the honda or toyota FWD setups. No room whatsoever.
Makes working on the FTO such a pleasure.

The alternator could of been in bit of a better spot though. I think thats why it dies abit early at times.

Why create 4.0L V8s? Why 5.0L V10s, why? Different layouts different engine characteristics. Manufacturers do it for a reason, not just to make life more difficult for their owners.

below link is a great source about how car engines work and why there are different settings. such as inline, flat and V, also their pros and cons.
http://auto.howstuffworks.com/engine.htm

V type engines are much more smoother and as a result they are more reliable. However, increased manufacturing cost is the downside.
Also, in theory, 2lt V6 engine should be more efficient than 2lt inline. The reason for that is simply doubling up the engine size without adding additional pistons does not provide twice as much power.
For eg; lets imagine an inline 2lt 4cylinder engine.
2000cc/4= 500cc per cylinder which lets imagine produces 150hp overall.
Increasing the volume to 1000cc (4lt 4cylinder engine) per cylinder will not result in 300hp overall.
Due to the reason that efficincy will drop sharply, reving of the engine will be very rough, etc. etc.

I think the main reasons why Mitsubishi choose V type instead of inline is efficiency and reliability.

We have reliable and powerful engines which does this without spending too much fuel.

BTW, I am so not a MeCHANIC

maybe mitsubishi couldnt get the power they wanted out of a 4.... just because honda could do it, doesnt mean mitsu would definitely be able to do it...

Usually high revving engines are a short stroke engine therefore less torque is produced. Perhaps to combat that they used 6 cyclinders to help even out and increase the torque spread. Allowing a smoother delivery of power and torque than an inline four cyclinder would. ie Honda.

I reckon the FTO is far smoother than any Integra or Prelude ive driven. Also the power delivery is more linear than the VTEC YO!!!!!. Hondas have absolutely no power before VTEC YO!!!!!.

apparently my ears like the FTO 6 more then the honda 4's.
*shrug*

and the FTO does?

Yep. Mine has as much torque at 4700 as it does at 6200...

Hmmm if it had been a 4 cyl maybe it would have been a twin turbo... like say the VR4 engine... scarey...

I love it anyway, nice grunty V6... and then the people jump back onto the curb when the mivec kicks in... *tingles*

and im sorry but 120kph in second for a stock engine is enough power for me, but i have to say the engine bay does look kinda naked with a 4 cyl engine in it... doesnt quite have the same appeal

sounds right to me
i tested teh 1.6 VTEC YO!!!!! CRX before the fto, wasnt very smove or nice to punt around. i mean it was effective but when you lowered the gears on a corner your jsut like'wheres my engine response' i only have that problem around 5-6ish k at the black hole point we have :/

the fto even uses less fuel then my bros s15 2l turbo (once apon a time when it was 150kw stock).

only problem i really have with the engine is that we cant mod it to 300kw easily

but then fwd too...
