All engines have a powerband. Vtec's powerbands are just impossible to find.
No, Mk1 and Mk2 petrol models had Zetec (belt driven)engines. Mk3 petrol models have Duratec (chain driven) engines. All diesel models have Duratorc engines
The VTEC system can not simply be hooked up. It is only found in certain Honda Engines. To install VTEC in a non-VTEC car the engine must be swapped in.
There is a difference in a 2.3 non-VTEC and a 2.3 VTEC head bolt pattern. Since the patterns are different, the engines cannot be switched without modifications.
Yes
The standard engine in a 1999 Civic EX is a VTEC engine. It should say VTEC on the valve cover. there is an engine code printed on the block itself if it is a sohc vtec it will read "D16Y8" on the block, plus vtec engines have something called a vtec silenoied located near the distributor. Actually the D16Y8 valve cover does not say VTEC on it.
non-vtec d16 engines have about 106 horsepower
You can use any d15 series motor as long as it is not vtec. But also it isn't to expensive to switch to a d15b vtec motor you just need vtec ecu and wiring harness that can be found for about $100 on eBay. I switched my car from d15 non-vtec to d15b vtec for about $650 including the price of the motor.
I'm pretty sure it would be a NO considering vtec engines have camshafts specifically made for high rpm use(when it kicks in). normal cars cams aren't different from low to high rpm. certain Honda's switch camshafts from low cam to high cam when vtec is activated
yes EDIT: yes and no. not all D16 engines come VTEC stock. For sure the D16y8 does and maybe some others. you can always throw a VTEC head on a non VTEC D16 and make it one. People refer to that as a "Mini me" engine.
That depends on the engine you have in it. Different years have different engines available. I have accord 1999 LX 4Cyl VTEC has 150hp accord 1999 V6 VTEC about 170hp
Ford recommend 5w/30 for all their latest petrol and diesel engines.
