MIVEC vs VTEC

**Surrufus** · 03-06-2005 04:53 PM

wondering which car would perform better:
Mitsubishi Mirage with 1.8L DOHC MIVEC eninge
Honda Civic with B18C (1.8L DOHC VTEC)
if both are tuned and modified to similar levels

VTEC > MIVEC

*thread locked* lol

Mivec is incredibly over-rated in my opinion. If it were really good then it would have the parts support of VTEC but it doesn't and I don't think ANYTHING is available for the Mivec engines. A perfect example is putting a 6A12 Mivec engine into a Mirage. It is a big V6 engine with Mivec and even in a light Mirage a high 14 will be the best time it will do. Put a smaller K20A or H22A into an EG and it's a different story all together. Another good comparison is the new Colt vs the Jazz. Colt has a 1.5L DOHC Mivec engine while the Jazz has a 1.5L SOHC VTEC engine. The Jazz destroys the Colt on the road and this is proof enough that Mitsubishi sucks and Honda is the king

*How about vtec controllers that are compatible with both systems?

Think about that for a bit- That is exactly the same sort of comment i used to see coming out of all the other car related forums, only it has been levelled at hondas and vtec.

How about some of you give some technical explanations as to exactly what makes mivec better than vtec.

As far as i know they are conceptually very, very similar. I've even read snippets here and there about mitsubishi paying royalties to honda for certain parts of the system. I've always taken that with a grain of salt but you never know...

Feel free to correct me as necessary.

Mate I mean't engine parts. Air filters, exhausts and controllers don't count. The only part I have ever seen for a MIVEC engine was an ARC intake manifold and the gain was crap. I am yet to find any cams, headers or anything internal for the MIVEC engines.

Sir. yes Sir.

Agreed !
I give

a

and Mitsubishi a

I believe VTEC engines run higher compression as well.. correct me if I am wrong.

WRONG, theres 2 factors effecting engine power, that is size and compression, hondas vtec takes the third way of timing. mivec vtec tetech setech shittec is all the same thing on all cars and nearly all cars have variable valve timing elec control but the design of the engine is just different thats why a ferrari costs 200k and a civic costs 25k and they both have vvtec. So you figure it out, do you think a mitsubishi would be faster or a honda with basically same epecs? you think honda got it's name by designing the fastest donkey chariots? its just that mitsubishi engines are inferior to hondas.
