okay so I know theirs vtech what's that I think it's just diff heads thats about all.... and then b16 is reg... 1.6l then h22 is a vtech 2.2liter... how does all this work.... thanks much apreciated.....

Is all honda guys do is engine swap these babys? Thanks nick!~

turbo ext..... thanks

 

Well first off it'sVTEC not vtech (thats the toy company), and their's all kinds of motors for honda's. It's just not the different heads on each other, its the whole motor in all. True you can fit every d-series head or block on different d-series motors all protains to b-series, H series, & K-series but youCAN'T mix and match. Ex: D16z6 you can put a y8 head on it to be a d16y8 but theirs more to it than just that, you'd have to change over the wire harness to OBD2 to OBD1 etc. But here's some motor codes thatI could think off the top of my head.

B16A- JDM 1.6L DOHC VTEC
B16A- JDM 1.6L DOHC VTEC
B16A2/3- USDM 1.6L DOHC VTEC

Those are just a fewI could think of off the top of my head.

Now on to how VTEC works?

If you have ever read how a car works, you know about the valves that let air into the engine and let exhaust out of the engine. You also know about thecamshaft that controls the valves. Thecamshaftuses rotating lobes that push against the valves to open and close them.

It turns out that there is significant relationship between the way the lobes are ground on the camshaft and the way the engine performs in differentrpm (rotations per minute) ranges. To understand why this is the case, imagine that we are running an engine extremely slowly -- at just 10 or 20 rpm, so it takes the piston seconds to complete a cycle. It would be impossible to actually run a normal engine this slowly, but imagine that we could. We would want to grind the camshaft so that, just as the piston starts moving downward in the intake stroke, the intake valve would open. The intake valve would close right as the piston bottoms out. Then the exhaust valve would open right as the piston bottoms out at the end of the combustion stroke and would close as the piston completes the exhaust stroke. That would work great for the engine as long as it ran at this very slow speed.

When you increase the rpm, however, this configuration for the camshaft does not work well. If the engine is running at 4,000 rpm, the valves are opening and closing 2,000 times every minute, or thirty to fourty times every second. When the intake valve opens right at the top of the intake stroke, it turns out that the piston has a lot of trouble getting the air moving into the cylinder in the short time available (a fraction of a second). Therefore, at higher rpm ranges you want theintake manifoldto open prior to the intake stroke -- actually back in the exhaust stroke -- so that by the time the piston starts moving downward in the intake stroke, the valve is open and air moves freely into the cylinder during the entire intake stroke. This is something of a simplification, but you get the idea. For maximum engine performance at low engine speeds, the valves need to open and close differently than they do at higher engine speeds. If you put in a good low-speed camshaft, it hurts the engine's performance at high speeds, and if you put in a good high-speed camshaft it hurts the engine's performance at low speeds.

VTEC (which stands for Variable Valve Timing and Lift Electronic Control) is an electronic and mechanical system in some Honda engines that allows the engine to effectively have multiple camshafts. As the engine moves into different rpm ranges, the engine's computer can activate alternate lobes on the camshaft and change the cam's timing. In this way, the engine gets the best features of low-speed and high-speed camshafts in the same engine.

That'spretty much thebasic way an engine/ VTEC works. If you want tolook into more if yourintrested then look it up on the internet.

 

THANKS A LOT!

 

I'm thinking about geting a 1990 Acura integra with the heads off because the piston gotmessed up from the Valves... B16 1.8L DOHC original engine.... I don't know should I put the same engine in or what engine is recomended with not much more then bolt in..... I want ot use the same wiring and trany....... I don't know much about hondas/acura I do know a bit about fords/chevys.....
What should I do while I've got the engine open for turbo in the future I don't know about that though

 

wait it not a b16 1.8 casue there no such thing he said it was a b16 nonvtec i'm not sure I'll get back to you guys on that thanks

 

b18A1 for sure........ like I said no manifold and piston #2 the valves went into piston
