Imboxed about motor

Hey guys my motor recently blew a piston ring in cylinder 6 it will be taken out and givien to engineer this week it had the following Hks 264cams Hks adjustable cam gears Port polished head Yellow Jacket coilpacks 700cc injectors R34 turbos Std bottom end N1 pump Power fc Tripple core radiator Now im obiously doing the bottom end Whats the best motor i should put together to hold 350+kws maxin at 450kws Names Prices I will not be dpig the head as its already done I will be gpong single turbo this time i pusshed 273 kws last time want to go bigger Go....

Great guys this is much help and i will explain this to my tuner once car is rebuilt and ready to go this has helped me understand rb26s more as im a 2jz man lol but thanks guys will be starting a build thread and askig for sole tips soon

Im pulling the motor out i took it to tuners to double check my results and he cane to the same conclusion 6th cylinder piston ring, but what he can tel is what caused it an injector? A pwer fc fault? A bogged spark plug? Spike in boost we jist dont know

The cylinder didnt die nor f**k any valves the car starts idles and drives fun with. O hesitation just loss in performance and blows smoke. Now what does this build need for it to never happen again i am not requiring some epic 1000hp build i just want a build that will not knock from a stupid bearing and will hold 350-400kws safely to drive when i want to thats what i want!! Forged pistons,rods and acl bearings?

Running apexi fc 18psi hes telling me all AFRS were perfect and timing was abit morw then standard! Hes nowing sayin a blocked cat could f*k the tune (its been punched out and cleaned when exhaust came off) 6th injector could have blocked or not working properly? I dont get that shoukd it not show up in anyway wow or form? Hes saying it might have just been a warn cylinder and lost pressure? Bullshit the car was knocking on the fc after the tune and ao he pulled timing on it and atill was knocking

Just doesnt make sence to me bro hes bot afmitting it i hust had the car at hes garage hes saying he pulled the timing out as much as he could and had it on safest tune but 24hrs later after dyno it drops a cylinder like wtf?

Lol anyone up for mint con 96 gtr vspec with one dropped piston ring

Cylinder comp test on cold i just did one on warm showed those results im not to worried about 1-5. They all show same its number 6 at 70. Now the question remains why it happened and what part went wrong and do i blame my tuner it lasted 2 days of dyno

Ok guys Reading for conpression test Cylinders 1-5 128 Cylinder 6 70 Guess its a piston ring after all

The pinging was only here and there maybe happened 5times worse was 109 on knock sensor but after i changed spark plugs and drove it around stopped happening doesnt happen in any gear now? Smoke accured after laat drive on sunday

The fact it doesnt do it on idle when cold shows me its only on revving down from high rpm and underload on boost and on idle when revving it! I dont think turbos it might be but i dont think so there was a smir of oil in Y pipe i think valve stem seals or maybe a piston ring landin

Nothing no smoke when i remove cap or dipstick! When i remov the hoses for pcv system i see smoke coming out of the hoses? Just a bit like very little smoke. I will rip of all the piping tonight and look closer to the intrcopler for oil because i removed the big ass intercooler pipe near the Y pipe and smir of oil pn the pipe so thats why i discard it from being turbos though ill take of the pipe to the cooler and see if its all hanging down there i want an excuse to go single loll

Ok i am guessing it is valve stem seals as comp test shows all same readings across the board. Turbors are very non responsive but still making boost just not as aggressive so thats 1 problem but im saying valve stem seals purely because it now happebs in 3gear and 4 th when i give it to about 6-7000rpm abd deexcelerate and let the rpms fall smoke gushess out everywhere like a bush fire abd its blue. Its there when im boosting it but jot as much as when im deexcelerating the car so my gues is valve stem seals i put oil thickner with 10/40 and did nothing at all?

Ok 0406456656 text me ill take it

If someone is a skyline tech and can come to my house tomorrow and find me the reason to all this shit i will pay you give me a price and ill pay i just want to know wtf is going on live in sydney

Blows alot of blue smoke when revving it on idle like alotttttt! But not as much under load

Ok my comp were 160s across the board. I changed oil put oil thickner in it and it stopped blowing blue smoke under boost only sometimes and now it just blows on idle when revving blue smoke occurs and when coming of the excellerator underload it blows blue smoke Its now blowing alot of black smoke and big flames and all of a sudden theres no performance in second gear! Third gear is coming on boost but not as it use to very slow and not as crazy. My dipstick is blowing anymore and i checked my pcv hoses including one to the turbo and theres only a smir of oil but theres smoke coming out of the hoses have no idea what that means but no oil at all? Im leaning towards turbos only because the performance of the car is really bad and it all of a sudden running really f*kn rich? Any thoughts i will not purchase a catch can if theres no excessive oil coming out the breather system. Maybe valve stem seals? Any ideas im leanig towards turbos guys but again therre was only a smir of oil in the intercooler pipe nothing crazy

Im guessing it was overfilled by atleast 2 ltrs but it was never blowing as much snoke the. Last couple of days so doesnt make sence. We will see soon what happens but atm still no idea

Yeh my dipstick popped out the other day while driving and im thinking because of overfilled oil and im guessing atleast 2ltrs came out and it was atill way pverfilled on the dipstick and it popped again and let oil out and still overfilled Im going to do oil change tonight and put lucas neil additive to thicken the oil and see if it stops the blowig smoke if it does then we know its rings and if it doesnt at least minimise th smoke then turbos

Im hoping its turbos i will do comp test and put up the results tonight see what you guys think The oil was overfilled by atleast 3.5ltrs my negligence wouldnt that make it blow smoke?

Im hoping its turbos i will do comp test and put up the results tonight see what you guys think

Also my knock sensor shows high knock in 3rd 4 th since blue smoke arrived

The engine was sitting for 4-6months without use on a crate. The engine was never blowing smoke and all of a sudden it just started blowng smoke doesnt piston rings occur slow? Boosting ceramic turbos to 18psi I will check for compression if all good then would it be the turbos?

Ok so if it was turbos that means it wouldnt blow into the exhaust if it blows into the intercooler? So most likely its motor? If its motor and i run a catch can will it fix the issue partially? The car doesnt go as hard now the blww smoke has come
