the e-vtec shouldn't matter at WOT. i thought the shutting down of one intake valve was just cruising.

E-Vtec is basically the econo version of vtec as stated in the above posts. The main difference lies in the cam, ecu, and head. (not to mention the intake manifold flows like ----) Until 2900 rpms the engine runs on 8 valves (very lean setting indeed) thus using a signifigantly less gas, mix that with a long tranny and you can show a huge gain in gas milage. Big thumbs down for anyone on reading this on this site. The internals are weaker that those of the y8 and so is the bottom end. As long as you are not spooled up before the engine switches back to 16 valvles (at approx. 3000rpms) your not goin to harm it but it is by far not the most effecient engine for preformance. I started out working with a 96 hx which comes with the D16y5 Vtec E and ended up droping it for a obd1 d15 with boost. So stoked I stoped messing with that ------- vtec e

instead of throwing down for a motec or standalone get a real motor .. hell even a d16a6 would be better than that thing.

ok.. u said the stock motor is 114hp. is that the factory rating? dont forget the factory uses crank hp while when you dyno a car it measures hp at the wheels.

114hp = 100whp
155whp = 180ish

65hp jump is good for such a little motor.

D16z6s made around 100Whp, I doubt the vtec-e would be within 20hp...

88crxSi

either way the nuumbers dont matter its my point that was accurate :P

89dxhunchback

Very true, you point was right, just wanted to make it clear he did add like 60Whp...

you guys are streesing me.
now i feel my car is ---- and useless.
I feel it, as soon as I blow the engine i'll go for a swap.
D16z6 is not bad.
thanks guys, anyway iam mounting a second fuel pomp to increase the pressure on the injectors.
shame that on the VAFC i cant set the VTEC to engage from the begin ( like an all time engage ) or maybe i could play with the selenoid that is on the left of the head?
this is a pic of my engine


and thats my car.
i do races with it and i participated in few championships, once again ill say thanks to all my sponsor because without them i could never afford this sport :P

If you are happy with the power it makes, don't change it.. Just b/c the guy down the street has 800hpdoesn't mean I'm going to run 30psi on my stealth TT to try and keep up... ( or in your case swap motors ).
