Ok, I thought it would be a good idea but just confirming things. This is my first Nissan rebuild so parts that are actually easy to buy is new to me.

I can only find 3 pumps, n1, tomei and nitto. I'm pretty sure that the tomei and nitto would be over kill, but what about the n1. Is it too big too?

For future reference. The valves listed in the ferea catalogue are different to the Nissan valves. My machinist ordered one in to replace my worn out one and it didnt have the step down for the retainers, $45 was what he paid for it. Nissan are supplying me with a genuine one for $34.

The machinist was going to replace one valve yes. I didnt realize it was a different sort of valve, I never saw it. The ferea was the only one he could find for the 25neo.

Yep. Also know the feeling of trying to work out a problem that seems so simple to others, and yet in the end has nothing to do with what anyone said. Chocco, not everyone here is an expert on cars, give the guy a break.

Lilcrash, sorry if I missed it mate, but have you explained how you have your breathers plumbed in? I'm assuming you're using a catch can and it's not just the stock setup yeh?

Like when my car wouldn't start, I tried everything then suggested broken camshaft, everyone lold and said no way, in the end it was an broken camshaft haha.

Just read all this thread, when you finally get it running again promise you won't run more than 10psi without getting it to a tuner first, get the tuner to strip out timing and make it ridiculously rich, even up in the load cells you aren't close to touching. Then go play with the actuators and get the right boost, once you have the right boost take it back and get it tuned at that boost.

Remember if you change nothing you will blow the new motor up just as fast, the issue wasn't with the motor, it was with everything else.

Should save a repeat incident. Good luck with it all. :)

I'm still confused as to what went wrong but yeah I am putting the smallest actuator I have here on I think it's about 7psi, depending on if I run it in on the road or on the dyno it will go straight to the dyno for run in or straight to the dyno after run in. I will get it looked over, dyno checked at 7psi and once I'm sure nothing is faulty I will put the original 20psi actuator ( that dropped to 14psi ) on and see what happens. hopefully It will hold 18psi to redline. If not il just put the 7psi on and turn it up to 1 bar and leave it.

Just for future reference, problems I've found so far - head gasket pealing apart, loose exhaust manifold nut( cause for the noise? ), inlet valve number 9 was about to drop as the retainer/valve stem area was worn and worn out rings in cyl 1

You ran 25psi without a tune, that is what went wrong. Even 20psi when tuned for 15psi will almost certainly detonate. I remember telling you in the hypergear thread months ago not to do this, all it takes is 10 seconds of sustained detonation and pop goes your motor is the result the majority of the time.

Don't do anything and see what happens, get it on a dyno first thing and do not boost it even once. Get the tune right, then play with things WHILST on the dyno. If you don't I can guarantee you will blow up your new motor.

Please DO NOT put the 20psi actuator on without being on the dyno. All your problems that you listed are caused by detonation.

yeah i meant i would be doing all the stuffing around while on the dyno. if its all caused by detonation then there is my answer, i didnt realize detonation could wear out rings. but it is good to know that the tune is to blame. so thanx *** *********** for all the problems you have caused, apart from the oil pouring out which was caused by the rings dieing due to prolonged detonation im guessing. that same detonation sound could be heard from the second i picked up my car, thats half the reason i called them 10 minutes after i picked it up, and never got a call back.

oh well new motor and new tuner, lets hope it all goes well.

I was on here asking questions about it when all hell broke lose in the first place.

I was never intending to make that much boost, I didn't really think the new actuator was that much bigger then my old one. Neither of the other actuators make the boost they are specified as so yeah stao said 22/23. I thought oh yeah 18/19.

    • Take a couple of the big ones back to "work", leave them in the big bin.   Will make a good boom when the garbage truck emptys it out... I've heard from another source about the boom when they had put I believe it was a 4cylinder engine in the big bins at Richmond base...
    • That idea has crossed my mind, I do a 5km walk everyday, this does take me past some bushland......I think you may be onto something 😉  That, plus 1 rock on every bin night might do the trick, it may take a year, but it could save me a couple of grand The only issue is the big 'Boonies", I have a few that weigh around 30-40kg, maybe they should be the first to go into the raised garden bed,  and then let the next owner deal with them....my daughter gets the joint when I kick the bucket, mums the word mate......LOL Noice......
    • Wow. Did you call the car a Nissan Skyline?
    • You're retired Mark, on bin night, go for a walk, kind of like you're doing the beep test. Put one rock in the first neighbours, come back, get another rock, go to the second neighbours, repeat over many weeks. All rocks eventually gone...
    • No chop chop of anything mate, it is what it is, plus, I don't want any air that isn't either going through the cooling stack or intake getting into the engine compartment increasing under bonnet pressure  Yeah, the Mazda Speed aftermarket intake above is less than ideal for multiple reasons, the requirement to remove the bumper every time you need to service the filter, and also smaller in diameter than the NC1 OEM one Weirdly, Mazda Speed is part of the Mazda motorsport division, "form over function" and $$$$$ for Mazda from unsuspecting punters I suspect  After some googling about them it seems they added no power, but do increase some induction noise Meh In other news, the electricians have been busy today at the house, and are back tomorrow finishing up all the security stuff and exterior lighting, they also added some lighting on the garage ceiling, which will come in handy when working in the garage when it's not freezing out there My Birdies raised garden bed also arrived today as well, which I'll put together and place tomorrow, it's a big tall Bessie, 74cm high, 92cm wide and 214cm long, this will come in handy as I am starting to get "stockpiles" of good soils from doing landscaping, some of the clean rock, namely the river stone, will go into the bottom of the bed for drainage, as well as the old Apricot tree that was out the back,  and when it's full, I'll grab another one, I will be growing enough veggies to keep me both busy as well as supplementing the shopping list I'm also awaiting another quote for a new Colourbond front fence, as the "1980 style cemented in rock edging" that was there and "fashionable at the time" looked arse, and my god, the amount of cement used to fix the rock was insane, it took 1.5 days for me to break out 12 meters of the stuff by hand, trim the bushes back to the fence line and dump it out the back of the joint to deal with at a later date,I will soon need a skip bin to tip it all Unfortunately they did alot of the cemented in rock around the joint, which I hate, so a few pallets of retaining wall blocks for around the front and back where the cemented in rock is will be required to bring it up to a standard, and look, that I will be happy with 12 meters worth of rock and cement Finished smashing the fence line and ready for a fence to be installed, yes, the lawns need some TLC and thickness, the previous owner trimmed the grass to the roots 😢, the TLC I can provide, and nature over time will do the rest And there's probably about another 40 meters worth of this landscaping abomination left to do around the front and back gardens, I'm guessing maybe 3 or 4 tons worth, tip fees for this will be a killer Meh, all in all I'm having fun and keeping busy, plus, it's good PT
