does this have a vtec engine?
No
Yes, Honda came out with the VTEC engine in 1989. Not all 1991s have the VTEC engine.
A 1994 Honda Prelude S would not have a VTEC engine in it (assuming it has the original engine in it). It should have the F22A1 in it which is SOHC and Non-VTEC.
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.
As far as I know yes.
Your car is VTEC already.
VTEC may or may not work when the check engine light is on. It depends on why the check engine light is one. If it is on because of a problem with the VTEC system, then, no, it will not work properly.
If im not mistaken , this can seen on the engine cover of the car... Big VTEC is normally written bigger than DOHC on the cover meanwhile small VTEC is written smaller which is smaller than DOHC writings on the cover. Big VTEC is normally b16b engine and second generation b16a engine. In addition, other engine such as h22a which can be found in honda accord 1995 and also prelude is big VTEC. Small VTEC is first generation of b16a engine and others. The VTEC engages at the certain rpm and varies for different model of engines. For example b16a big VTEC's swithover is at 5600 rpm where the valves engages. Small VTEC is underpowered compared to big VTEC and is almost can't be felt when VTEC engages. Big VTEC is very powerful, the VTEC engagement has a turbo like feel and it has 160hp or more, depends on the car. As mentioned above, the b16a engine delivers 160hp and 150Nm of torque at around 7000rpm.
No, the only 92-93 GS-R models have the 1.7L VTEC engine; the RS/LS/GS models have the non-VTEC 1.8L. It will say on the Engine if its a Vtec
No. The first Accord with VTEC was the '94 EX model.
From the factory, a 2000 Honda Civic EX engine does have VTEC on the intake side only. It does not say VTEC on the valve cover, and in stock form you normally cannot tell that it is working, but it is there.Unless the engine has been replaced with a non-VTEC engine or you are not operating the car correctly, VTEC should be engaging at around 5000 rpm while the engine is at normal operating temperature.
