DOHC i-VTEC or DOHC VTEC better?

[aaronng]

in the newer versions of honda the dohc i-vtec engines you get 2 types of vtec. there is the "power vtec" in the k24 engine in the euro for example, and the "economy vtec" found in the k20 engine in the euro also.
the k24 engine in the euro has got a very similiar vtec system to the older dohc vtec engines but with cool things like the vtc added and the k20 engines in the euro and other(crv, us accord and civic si) have similar systems to the vtec-e found in the 92-95 vei 1.5l and vtec-II found in the 96-00 lsi 1.5l sohc engines.
the newer engines have the vtc added so it´s more economical and more torquey through out the rev range.

Civic Si has the DC5R engine.

No, the K-series does not have VTEC-E. There is only ONE type of VTEC in the K-series. The only difference is that the Accord, Integra Luxury and CRV's engine have VTEC only on the intake cam. The Euro, DC5R, DC5S, CTR have VTEC on both the intake and exhaust cams.

Because the S2000 came out in August 1999 in Australia, while the first car with i-VTEC was the Stream which came out in October 2000.
Your info is wrong.

05 S2000 comes with Vtec and not i-Vtec... that tells u why Honda still prefer VTEC for performance car!!

lol thats because its still the same model for the s2000 there was nothing changed except for some minor things like start up engine etc. but everything else is still the same. changing engine will cost them a fortune. s2000 doesnt sell much compared to the other cars in honda. they sold about how many last year? it costs too much

my 2 cents

the first 02-05 si civic and base rsx 02-06 did not have that engine they have the same engine as our 2l accords. theirs is just rated at 160hp.

and yes the k-series does have a system similar to vtec-e/vtec-II. and yes only vtec on the intake cam.

LOL, that's because it has the same engine as the 1999 S2000. The USA's 2.2L is a stroked version of the F20C. That's why it also uses DOHC VTEC.
