    the valve could have been damaged from the initial failing of the conrod, then when they done the rebuild put the valve in a different position in the head so not on the same cylinder.

    this thread is turning into an epic adventure!

    I wonder if the phantom misfire will return once you get the new engine up and running!

    Also, I wonder how the large port AGU will perform with all the APY parts fitted....

    when you say that the agu has large port, do you mean it uses bigger valves?

    how come you did'nt just use the AGU engine with the forged rods?? id definantly have used the larger port head if i were in need of replacing the engine also why use the APY pistons over the AGU's when your using the AGU block??? be quite a good setup with jbs mani hybrid turbo and a nice little map from bill

    just thought what inlet mani will you use then as AGU will use the opersite side intake?? and the APY will be small port so will be no good surely?

    No, the ports are larger :p

    hahahaha. Sorry, that sounded rude!

    The AGU had larger ports in the head. Later engines had smaller ports, which increases speed of flow, apparently helping low down torque, although ultimately, an AGU can flow better at the top end.

    Yeah, the inlet ports are about half an inch width wise bigger. The difference is massive. I will take a photo of the two next to each other before tomorrow's refit so you can see.... The difference is huge!

    Low down torque is the reason I wanted to keep the APY head really. But that's not the way it's turned out! lol. Plus the APY rings look to be in a bit better nick on inspection.

    Prawn, I was only keeping the pistons from the APY as I was keeping that head. Now that I am using a complete AGU engine, I am using the AGU pistons. Interestingly, they seem to have much more substantial gudgeon pins....? Same size at 20mm, but the ends on the APY's gudgeons are coned.

    Anyway, piston refitted tonight, all back to hunky dorey again. Head will be ready at 11am tomorrow. It was ready today - but the head gasket they're providing hadn't arrived so I thought it was easier to get all in one go!!

    So, round two begins tomorrow. Lets hope we have a spot more luck this time.

    Bill keeps a special inlet manifold which is about 2mm+ thick, and fades one to the other. Genius bit of kit. Might look at, in the future, getting an inlet mani made, but that will do as a quick fix.

    Awesome - I'll see it when I drop that block off. I might even bring it up tonight if I can. I've booked this avo off work to really crack on and hopefully get it done fingers crossed.

    to be fair it was a pretty dumbass question on my part, but thanks for the reply :icon_thumright:


    coolio mate, cheers
    how much of a difference in torque are we torque-ing? (im sad, i know!)

    just thought of a question for bill

    would the large port head be a better option for a k04 hybrid setup due to the torque being raised up the rev band thus giving less torque spikes or are these differences in large and small port not going to make that much a difference in the real world,
    looks like your setup could be an awsome hybrid turbo set up if my theroy is correct especially with the forged rods

    wtf? a whole evening passed and Welly didn't update this thread. Either he's fixed it and enjoyed driving it all evening, or he's fixed it, only for the phantom misfire to return mid bend and send him spinning into a tree.....

    largeport head will eat the volume any k04 can produce, hybrid or not.. so I would expect less torque spike but probable lower rpm where its falls off boost as sustained flow will not be possible.. the choke point of the k04 hotside however and exhaust manifold remains tho, so although the head can flow more the overall system is still held back.. will be interesting to see logs once its back together and see how boost abd airflow hold up

    I was sat in the corner crying and rocking whilst..... I didn't even have the strength....

    Last night was NOT a good night at all.

    First, the head gasket got put on upside down by someone who I asked to put the HG on.... Whoops. Bolted the head down and timed up. Filled with coolant. Leaks like a bitch. Realise what's happened. Unbolt head. Replace (now absolutely shafted - bin bound) gasket - correct way up.

    Bolt all back down again & time back up. Fortunately we didn't pull the pin on the tensioner (more on this later).... Bolt the coolant pipe to the side of the head. Fill with coolant. Leaks like mad from the pipe on the side of the head. Take pipe off, inside all cracked. Find the on off the other engine - not exactly the same, but close enough. No O ring for it though. Fill O ring hole with instant and bolt on (hope for the best!!) and reconnect pipes....

    At this point decide it is time to pull pin out of the tensioner to finish the timing belt. Pin snaps leaving tensioner locked down in position. No room to do ANYTHING about it obviously as the engine mount is in the way.

    So at this point, I decided to pack it in. Fitted 2 heads last night basically and was cream crackered!!

    I've got some good photos of the AGU/APY port comparison though which I will post tonight (forgot my camera this morning).

    So, all of that combined with tools seemingly growing little tool legs and running off, made me unhappy.... I must of spent an hour looking for things last night (and that REALLY bugs me!)

    I would of thought that the N75 duty cycle will take a big change from before from where the management is trying to produce the requested boost against that head....? Turbo will be balls out all the time!

    savage. the battle goes on. i get the "cant find a thing" syndrome towards the end of the night when im starting to get tired. thats when you start to make mistakes too which is annoying. id put the front of the S4 lump back together and forget the dipstick tube which basically should have gone on first but managed to wiggle it in somehow

    bet youre looking forward to the test drive sooo much

    Request boost will be the same - ecu will still ask for the same, and control the n75 accordingly
    you will find the n75 is already at 95% max on the high revs before largeport... as the map asks for the max and the turbo does not achieve it

    there may be some spool chnage on big port yes.

    Head Gasket upside down??? c'mon......... which muppet did that?
    Sequence wise, I pull pin and time it up before refitting the mount - not as you did it. (often it takes a couple of bites for it to settle on timing mark)

    A mate of mine you haven't met. And you won't now since he is now dead. Mystery death involving being choked by a large pair of Stilson Grips.... How that happened I don't know..... lol.

    i had a mate of mine "helping out" on a cambelt job a while back. i could hear him heaving away against something, i look down and hes laying there with coolant running down his arm

    "wtf is all that water doing?"

    "dunno"

    he was slacking off the pas pump but was pushing the water pump by mistake and made it leak through the bearing somewhow. 3pm on a saturady so no access to any parts.

    tell me about it, when I changed my steering rack, whilst the subframe was off, i came over to the car to find my mate aimlessly spinning the steering wheel over and over again, asking ''how many times will this spin before it stops?''

    Clock spring obviously broke. bastard.

    Was there a nasty, tool related, death involved there too? Such as claw hammer in the eye? I was so tempted to see if I could MAKE one of the cylinder holes in the head gasket he broke fit over his head.... Would of been a squeeze, but possible in the mood I was in, I have no doubt. lol.
