Most likely you've ended up with a reasonably bad boost leak....do you have a boost gauge, and if so what does it show.

Go back around the whole job and check every hose is seated square, and every hose clamp is tight. The easy way to check a hose clamp is to push hard on the screw part - if it turns on the pipe it is too loose. But even if they are tight, the hoses have to be properly seated on the pipes, ie square on and good overlap

Howdy,

thanks for all your input!

I Double checked the hoses and een had a mate of mine come by after I had installed it yesterday to ensure everything had been connected properly. No problem.

I spent all day wiring up a boost guage (Apexi mechanical) and finally got it to work.

on idle: -0.5 to -0.6

driving: -0.7

OK, so im assuming it should be idling on 0?

No, that sounds reasonably normal. Engines are almost always on vacuum (ie less than 0) because they suck air in. the more you open the throttle the more air they suck so the more vacuum you'll see. But with a turbo car of course, as it comes on boost it moves from vacuum (negative) to boooost (positive), but only when the engine is under load.

Unfortunately that means that you need someone to watch the boost guage while you floor it for a while. Up a hill is best because boost builsd more quickly and the car accelerates more slowly.

OK so took it for a drive today and found a steady incline.

During acceleration, the gauge hovered around 0.5 and whilst in 2nd gear at around 3000rpm onwards I could feel the car 'stuttering'.

Thoughts? I think this is getting a bit too over my head for me.

Finished stripping the heads off today and cleaned up the block ready for the new oem head gaskets and L19 studs. It all looks pretty clean in there now, hopefully an oil flush will clean out any residual coolant I haven't managed to get to.

Luckily it looks like just a split head gasket...

Today, i pulled the glovebox apart to investigate what sorts of plug connectors the DVD rom's got, and found the glovebox light was blown. Replaced the bulb, all good now. Also cleaned the pollen filter. Still not able to get the reversing camera wired up as the camera wont work for some reason(ntsc). Also gave it a wash. :yes:

Gotta love how E85 keeps the pistons and combustion chambers clean.

Is that the knock sensor in the valley?

yeh i asked him if it was yesterday and yeh apparently it is the knock sensor

What's this Aaron? A non random post? That's not like you...

Yeh Paul, the pistons were only a little coated in carbon, a light spray with gasket stripper had them polished like new.

And yes, that is the knock sensor, not that the Fcon cares about it much.

In Pic 1 is that a cast mark on the engine mount or a crack ?

could the issues that I have been experiencing be a coilpack issue? I remember experiencing something similar with another car of mine years ago..

It sounds like it, Stuttering is usually either plugs that are fouled or coil packs breaking down. It could also be low voltage/bad connection in the coil loom. Without more information about the car's mods and power level its hard to guess the cause.

Studs turned up today, all went in well bar one, it looks like the thread is a little chewed. :verymad: I will have to buy a long M11 x 1.25 tap tomorrow.

I also match ported the upper and lower plenum halves and throttle, the head ports looked pretty good but the runners were all over the place.

Nope. lol, I don't trust myself around the valves without removing them and I don't want to get a stray piece of alloy in the oil galleries. Do you think it matters? The area of the 6 ports is a crapload bigger than the turbo and wastegate. It should be fine mate. There is definitely a heap of material I could remove there though.

im gonna talk you into it lol..

i think you should.. why not its all apart.. just be a true hampton parker and shove a sock down there and vacuum it out before you take the sock out lol

    • Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.
    • My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though. 
    • Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno
    • Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
    • BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
