95 r33 skyline Unopened rb25det Stock Injectors, maf, fuel pump, airbox Power fc Blitz return flow Splitfires Hypergear 21u high flowed g2 profile at 18psi Avcr Maf and Injectors maxing out. This seem alright to you guys? or could I squeeze some more without upgrading Injectors, maf, etc

all done, just had to swap out throttle bodys and the bracket for the throttle cable pretty much, they had slight differences, tps being the main thing. CAS was the same half moon. Cars running good, water temps wont go higher than 70degrees though, guessing thermostat only thing that would cause it?

https://www.facebook.com/stevosautoelec/ This dude for sure, he installed my alarm in my car, got rid of the mess under the steering column and everything looks factory. Unbelievable attention to detail and a really great guy knows his stuff.

alright sweet, changed the coils around, its already got a cas in the new engine so i assume the plugs are the same if they are different? im pulling the engine with the gearbox on it, is there a way to stop the oil coming out the back of it? i know with my mates subaru we just used a lid off a spray can to block it off so no oil comes out the end. Anything similar i can do or do i need to drop all the oil (i changed it recently so would rather keep it)

RB25DET S1 S2 engine difference Just got a new engine to drop into my 33. Came with a s2 engine and engine im putting in is a s1. Wondering if theres any difference between the two beside the coils which i can just swap over. Injectors, intake, accessories, etc all good to just plug straight into my s2 loom? Or should i just swap over the intake manifold side with my s2, just want to save some time.

Haha my last post sounded back but yeah was at tdc and at temp. My tester was just a bit weird and wouldn't go to 0 while still having air go through it. So when I was testing the needle wasnt on 0 so I don't know exactly how much it was leaking but it was moving and the air escaping was definitely more noticeable than the other cylinders. I found a long motor for 900$ good health 155 comp per cylinder. So I figured why not just swap it over. Either way it's burning quite a bit of oil and probably won't be able to fix it without at least taking the head off. swap them over at home with some help from a mate. Get to learn a bit as well. Also have a turbo coming this week so I'll just drop everything in at the same time.

Alright finally got the leakdown done. Bad news piston 1 rings. air leaking through dipstick/oil filler cap. But compression was still alright. No idea how bad the leak is because my leakdown tester is a bit weird but definitely 1st cylinder. Thinking what to do from here? do i urgently get a new engine/get a rebuild done/just drive it for a little while till the first two options happen?

ok boys well this weekend didnt go to plan, saturday didnt really do anything beside weld and wire up my afr gauge. went to do the leakdown today and the bloody kits end that goes to the compressor hose was a different size. so during the week i need to get an adapter or something. and as i was doing all that i left the damn ratchet on the crank bolt and turned the engine on for like 2 seconds before i realised, and it loosend it, so had to put that back in. zzzzzz

Leak down tomorrow most likely, ill check pcv as well. Had to top up oil today again. Ive gone through about 2L in 600kms. Seems like a whole lot especially when im not smoking at all unless under load etc. Checked my catch can, bone dry. Any possibility of a leak somewhere? but nothing under the car so doesnt seem like it. If i leave the car sitting and dont drive it oil stays at the same level. I checked my intercooler piping, pretty much no blowby, throttle body clean as well as my dump. Noticed today as well sometimes when i take off at the lights, not aggressive or anything, but i can really notice the smoke the, its not insane but enough to see out the back window. Anyway, lets see what this leakdown tells me.

Checked the oil. done ~80ks since i topped it up and its lost about 100ml. Cant see anything in the catch can checking window thing but i havent opened it up to see inside. I changed turbo last month thinking the issue was the turbo because it was making some annoying loud whining sound. So i dont think its the turbo again but who knows could be. Turbo i put in has slight in out and back and forward shaft play, very slight. When I say blows smoke. Cold start is very very slight and clears quick. Can't see it in rear view mirror. The only time I can notice the smoke is on a heavy down shift or boosting. But that wouldnt explain my wet compression test not bringing my numbers up, unless the kit im using is shit. I want to do a leak down test but dont have a kit, gotta try see if one of my mates has one. It's now blowing huge amounts of smoke. But just enough to notice if that makes sense.

Yep blue smoke. I can notice it when i down shift sometimes as well. Last topped up the oil was about 50km ago, will check oil level in the morning to see how much, if any it has dropped since then. ill check my catch can as well. Im assuming if its valves, rings, anything the catch can should be picking up quite a bit? Ill have to check that on the weekend when i have more time. I have it plumbed in like this

Intermittent oil burn Noticed past few weeks my car (r33 rb25det) has been intermittently burning oil, some days it wont lose any, others the oil level would have dropped by about 1/4 on the dipstick (this is with about 20-50kms a day driving). No leaks under the car, car doesn't blow smoke unless im under boost, after a cold start theres a slight mist but clears quickly. With a warm engine and in neutral holding at 2k theres a bit of smoke. Put a catch can in last week, havent checked to see if its caught anything but also havent really driven it enough, Car still pulls hard no power loss from what i can feel. Smoke is a light blue sort of color. Did a dry comp test and results were 135, 135, 120, 120, 135, 135. Put some oil down the cylinders for a wet test and results didn't really move. Results arent great but im not sure my comp tester is the best either. But either way im thinking possibly valve seals? i took the pcv out and shook it but only read recently to try blow it and see if it only goes one way or something? Only mods are 3" turbo back exhaust, and a FMIC. Using penrite 10 tenths 10w40.

Fixed all the misfiring and other problems. But that whine is still there, just checked all belts, was none of those, checked the CAS and wasn't that either. Could it be an exhaust or turbo gasket maybe? the pitch rises the more you accelerate

Just put in the new MAF. got rid of the limiter issue, but still have the car jolting on me. Didnt take it for a drive but moved it back and forward in my driveway as a test, was just jolting me forward

ok so didnt fix the new issue and seems to be worse now. Car turns over and starts, then pretty much instantly stalls, if i manage to start it, it doesnt want to rev past 2500, at first though it was coils/spark plugs but didnt fix it, then found the 2500 limit, so im thinking air sensor. Cleaned out the maf, didnt do anything, let the car idle while i packed up and stalled, and still wouldnt go past 2500. going to try a new one and hopefully that fixes it otherwise im stumped.
