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
