Ok mate and wat am I looking for? Wat if there is carbon build up and can't see any munbers?

Is there anyway I can tell if an engine has forged pistons without pulling it all apart? Engine is running 160psi compressing at 151000 ks, but insure of engine history weather it's been rebuilt with forged gear or what the go is. Rb25det engine.

well i just rebuilt the engine and wanted to freshen it up a bit

hey, i have stock injectors in my rb25det and wondering if i replaced them with new standard 370cc injectors would it make much difference or would i be better for just having the ones in it cleaned? cheers, Baldwin

ok thank you, just thought cos oil was going through them when they're supposed to stop the oil that they might of been buggered

well i just would like to know if the turbo seals would still be ok?

well the bottom end was pressurised, because of the rings being stuffed. had to release that pressure somewhere and weakest point was turbo seals so was blowing oil past the seals into the intake.

ok this is the situation, i had massive blowsy, like a lot haha. and pulled it all down and pistons and rings a rooted. and I'm just trying to figure out if i will need to rebuild turbo because oil had been pushed past the seals? rb30 block? i don't think so. because to be sure id still have to put new bearings and pistons rings etc in it anyway, and mod it to fit the rest, more money and time

then risk having a shit ton of blow by in 10 000ks n still in the same situation I'm in now? probably a bit too much of a risk

Title says it all

Well every piston is chipped out between the compression ring and oil ring. However all cylinders are ok except for the fourth, which has a bit of a groove. As for the rings, other than that fourth cylinder the rings weren't too bad. So at the moment I'm on the lookout for a cheap block with cylinders in good nick, if I have no luck there I'll get then all honed out 20 thou to put .5 oversize pistons in it. Would anyone have an idea roughly how much id be looking at to get it bored?

ok im in the process of putting new pistons and rings in. will i need to rebuild my turbo now or will it be ok?

hello, how many cc injectors will suit a rb25det? stock turbo. for a 1996 series 2 gtst r33

i got 9 grand cash?

ok. ill get my mechanic mate do to a compression and leak down test. how much compression is good compression? i seriously can't thank you guys enough for your help

ok so i need to rebuild my engine? so the turbo thats in it will still be fine?

a few months after i brought my skyline (1996 r33 series2) the turbo blew the oil seals (I'm guessing) as it was using a lot of oil, blowing a lot of smoke and had a lot of oil in the intercooler pipe. so i brought a china cheap turbo off ebay as a temporary turbo, but it done the same thing after a month or so. then i found out a friend of a friend was selling a stock one out of an r34 with 70 000 ks on it and i was told it was fine. put it in filed my car with oil and drove around town and it seemed ok. still blew a bit of smoke but i just assumed it was burning some that may have still been in the intercooler piping. drove to visit mum 200 ks away and got pulled over for the car was blowing smoke. popped the bonnet and got defected for oil on the engine coming out of the blow off valve. also got defected for the bov but thats another issue. anyway when i got home i checked the oil again. almost empty so this turbo is no better than the other two. so 1st question; is there something wrong with my car as to why it keeps blowing the seals in the turbo or have i just been unlucky? 2nd question would it be cheaper to rebuild the turbo? or just have seals replaced whatever the case may be, or buy a new turbo? 3rd; where would i get it rebuilt or get a kit to get my mate thats a mechanic to rebuild it, or where would i buy a new turbo? i only want to rebuild the stock turbo or replace it with a new stock turbo. i just want to keep the turbo stock. thanks in advance as i really need you guys help! Baldwin.

thanks mate! ill definitely let u know. any idea where i can get these plugs from? will the local mechanic shop have then?

ok guys so i know there is quite a few threads about this but there are also a lot of different answers, so I'm looking for something more accurate. so i have a 1996 r33 gtst series 2 and a week ago it was fine. one day i got in it and drive it and every time i hit the throttle it has a horrible miss. SOMETIMES if i take it out the road for a drive it may be fine then later ill get back in it and its the same again. i pulled the coil packs off and the fourth plug had water in it so i blew that out n put it back together with excitement thinking id have fixed it but it didn't. i didn't actually pull the plug out, just dried out the water around it. please help me, this is doing my head in! Cheers, Ethan!

hey guys, my r33 series 2 window motor has given up, as they do. i have the problem though, of my window being all the way up, so i can't get the motor out! does anyone have any ideas ho i could get it out? Cheers, Ethan

oh yes "shudder" sorry lol thanks guys i won't machine them ill just buy slotted i think

hey guys. i have an r33 s2, when I'm up ay 100ks and i apply the brakes it makes a mad shutter and steering wheel wobbles etc. i'm guessing rotors? but just wanted to make sure before i went out n brought some. Cheers, Ethan
