Boosting 01+ cars
So i have a 02 w/ VVT and i'm looking at a FM2 kit sense mr. hydra is the only thing I've seen so far that lets me tune vvt. I really have no idea what my chooses are so any suggestions or info on 01+ car running 250whp bolt on systems?
and hustler keep your ball gags to yourself.

The VVT only operates on the intake cam. You can use any ECU you want and simply pin the cam halfway on it's range. The engine will run just like any non-VVT 1.8.
On a GT2860, you should make 250whp on 14-15psi with no help at all from VVT.
And concur... excellent first post. Make this guys a mod.

it's my understanding that it was also timing related and at about 6k it goes from max advantaged timing to stock timing in prep of redline, because of this you lose at lest 15% power. if that no true let me know but if you saying it only works on the intake cam could i just buy a 99 head w/ none vvt cam gear and bolt it on with my 01+ ecu and have the car run like nothing is wrong and no error codes?

the VVT is continuously variable all across the rev range. Great if you can control it, but not the end of the world if you can't.
At worst, you lose a few hp/tq in the midrange (3000-4500 off-boost) but we all know that doesn't really matter because with the cam at full retard (which it is when you unplug it), it makes better power above 5k allegedly.
I say run whatever you want and unplug that SOB.
edit: in fact if you remind me for the dyno day, I'll do a with/without pair of runs and show you all the difference.

The Xede can run on VVT cars. However it cannot control the VVT. You do not have to unplug it either.
Controlling that can yield about a 5%-7% power increase if you use a standalone ECU.

We have a similar problem, I have a 2004 vvt 1.8 engine, I'm thinkin about how to resolve the VVT question to use a HKS bolt on kit.
FM gives you a normal pulley and the engine looses the VVT, that is not really a must for a turbo engine, in fact it gives more torque at low revs and turbo makes it better.
Leaving it unplugged should be Hi revs mod, but if we leave it work?
The stock ECU will command it as usual, could it be good?
what is in terms on retard/advance the two positions differences?
bye

you can unplug it and get a cel light or un plug it, get a vvt controller off a blown motor (or something like that) plug that in and strap it down, vvt is off and no cel. we did this as a test to see if it worked but you car is considerably slower the accelerate and the top end felt the same. i was looking for a way to make vvt stay advanced at all revs or for at lest more revs. the new ecu looks like it will let me do this.

Jeff,
I ******* told you to sell that shitbox blue car and buy an NA. If you had an NA your **** would be finished by now, but you're in love with your gay dude headlights and steering rack so whatever.
