boost solenoid fail?

Recommended Posts

and all was going swimmingly well, shields and piping out, exhaust out, undoing studs on dump pipe and snap goes a stud, sigh, draining the radiator and taking a moment to vent before pulling the entire unit out.....slightly bigger job than anticipated, however on the bright side I have hear that a good idea is to port the wastegate so might look into that while the unit is benched. Any other ideas out there feel free to let me know.

ok , quick update, turbo is now benched, going to replace all the studs to the dump pipe as they look pretty shoddy, definitely shot wastegate actuator, had to put 20psi through it before it operated the flap and a pretty fresh breeze was blowing through the centre where the rod comes out the entire time. took some pics but can not paste.

I just leave it off, personally. Never had a problem as long as you tighten the manifold bolts/nuts often enough. :)

yup, how critical is it to replace the "k" brace the sits between turbo and engine mount, seen a couple of comments where they have not put it back on.

 

Its there for a reason, but it back on....

Swap the fuel pump and let us know. I'm sure the mechanic would have listened to it priming or rather the lack of it priming so you should be sweet after this.

 

It should be pretty cheap too as the pump doesn't cost much and it doesn't take long to install.

Yup he has given me the run of the garage so going to pull pump tomorrow can hear it prime but no pressure in the line

 

 disconnected at pump and turned key could hear pump prime but no fuel pressure

Good job on getting it sorted... It's a reasonably common thing to occur when fuel pumps are installed.

ok, well found a local dyno and tuner, prior to this I had fitted the turbosmart 7.5 psi actuator which was sold as direct swap for OEM model,  and took it for a run, max boost is now 9psi,  but still experiencing the engine shut down problem, put it on the dyno and found out the problem was indeed the ecu cutting the motor due to overboost, he said fuel was fine so not the fuel pump not supplying enough, and purely an ecu recognising overboost issue. Decided to have the ecu remapped to accept the extra boost. problem, ecu wont talk to his pc, so off it goes to someone up north who can fix the problem, he is covering the cost which is great, thought this over a bit and decided as it is in the shop for the next few days might as well remove the cat, ( O3 model, as I understand it I am legal by one year to do this), fit new injectors, new high flow air filter, wait for ecu to arrive then remap to the new changes. Have I missed anything, should I also remove my centre muffler? any thing else anyone can think of while its at the shop prior to tuning I should do. Plan to do valve springs, upgrade intercooler etc julyish next year at this stage.

If anything I'd chuck in a walbro 255 so you can wind it up a bit if you choose.

I just quoted that from your post. You can highlight a bit and quote only that bit.

 

Anyway I was wondering why their pc couldn't interface with your pcm and why ordering a new one is the best fix.

Ok quick update found a tuner and dyno have swapped out injectors for 1000cc sards , new cat back 3 inch exhaust (no cat) and high flow air filter, car being tuned to 10lbs dyno broke (coincidence not power) while being tuned so waiting for part from Aussie to finish tune have bought a walbro to fit when I get it back and thinking I might fit external trans cooler any suggestions on location and brand

and duh duh call from the tuner today, did a pull with the new gear and turbo sh*ts itself, limped the car home and back to the drawing board I go, new turbo needed, starting to think the move from Chev to Ford was not such a smart idea, gimme some help here guys, just spent 3.5 k on injectors, exhaust, filter and tune and now staring down the barrel of another god knows how much to replace the turbo, plenty on ebay, bugger all around Blenheim, any suggestions, who to buy off, what to avoid, can fit it myself, obviously got a free tune once all sorted and still looking to up horsepower in the future.

What a farken bastard ay?!

If it's only the bearing, you can get that replaced for about the $700 mark if you r&r the turbo yourself. You can buy a kit (scroll down the page a bit) and do it yourself if you're feeling deadly.

I've got a few stock turbo parts kicking around if you've wrecked the wheels, housings or shaft etc.
