Whiteblocks: Cam solenoids

[frpe82]

I have a B6304FS2 engine from 1998.

What I want to do is to install the intake and exhaust cam solenoids on the head. You know, the ones from the turbo whiteblocks...

Is that possible?

The electronics is nothing to discuss. That is easily taken care of with some ECU programming.

Are the cams different in some way to accomodate this function?
Does the B6304FS2 head from 1998 have the needed thingamapoop to house the solenoids?

It is hard to know when your only reference is the pictures in VADIS and a running engine in a car to look at. It is hard to see the inner workings of it all.

Post a picture of your engine bay. I don't think any whiteblocks in 1998 had VVT on the intake side.

No, the engine in my car doesn't have a VVT setup.
What kind of noob do you take me for :-P (just kidding...)

What I am asking is wether or not it is possible to fit the solenoids.

Or do you mean I should take a picture of my engine bay so that you can see what the head looks like and if the solenoids could be fitted at all?

No, different head casting entirely.

This. Also, you're going to need something more than "ECU reprogramming". Oil actuated cam phasing needs closed loop positioning control--you need to read in the reluctor disc, decode it, and control a PWM output according to your controller. Haltec and Motec I think have the ability to do this, but I'm not sure if it's to an arbitrary reluctor disc. Of course, OEM ECUs off cam-phasing cars have it as well, are you going to retrofit one of those?

[Alex Buchka]

The closed loop system that controls cam phasing on modern OE ECU's is very sophisticated. The MoTeC M800 is one of the only aftermarket ECU's I know of that has tunable VVT maps. Running VVT on anything else is a full advance/retard deal with a switched 5v output.

[the poi]

I just said that.

I know.

And Motronic is the ECU choice. I can get that mapped accordingly (I work for a chip tuning company you know :-P ). The problem is not the electronics like I said, but the hardware.

But now I know that the head is different. That has answered my question. Thanks! :)

Any other hardware that is different as well?

[Alex Buchka]

The VVT block is different as well. The cooling system was revised after '99 so the thermostat is in front of the engine instead of on the front right side of the head.

Amar I'll give you a penny for every post you make in performance that contributes. ;-)

just get the T6 engine already....
:-P

it will only have the exhaust side setup for vvt but you can drill the ports on the head, add the second actuator and install a vvt intake cam from a NA motor

That is my plan for the future, yes. That will be the case when the T6 gets installed.

I was just thinking it could be done on the current engine as well, but I was proven wrong.

If you only run one.. You could get away with AEM ecu setup. I am pretty sure it wont control two. Thats why people dont use in on any BMWs with dual vanos.

Controlling the exhaust side VVT is completely pointless. There are no performance gains to be had. OEMs basically use it to heat the cat up faster.

You're always so ****ing negative

[amargill19?]

is it possible to control the exhaust side sort of like a big rig, where you can hold the exhaust valves open on the upstroke and downstroke like a jake brake?

Motronic will be used.

For others, yes, then AEM will be the way to go.

I don't know about performance, but you can definitely use it to increase efficiency at a cost of performance.

performance wise you can adjust the overlap between intake and exhaust to maximize airflow (a little) at all rpm's rather than just one set RPM

Bump. If you're looking for a T6 motor Fred, we should talk...;-)

cheers

The UK seems to be the best bet yeah, was tempted to pick up one there myself haha. Not that i have much use for one though.... ;-)

Yes, next year will hold a T6 I guess. But now the only thing I have to concentrate on is to be able to survive. I am still poor as hell. The performance related bits for the car will have to wait for at least another month until I can catch up.

[foggyjames]

There's no shame at all in that. I put my performance projects on hold and bought a 'normal' car while I sorted out things like getting a job, buying a house, etc. **** happens.

cheers

I feel dumb: is this a completely camless setup, as in one solenoid per valve, or more like vtec where the solenoid switches between 2 profiles?

[Lord Tentacle]

roller ramp
big spring inside the timing gear holding it at full retard, as the selonid lets in oil pressure the oil flows into passeges in the cam shaft and into the cam gear and it pushes things to cause the cam to rotate in relation to the gear teeth
