hey guys im probably being paranoid however i started my rb25 for the first time in about 3 weeks let it idle til it warmed up (idled fine and reved fine) when i turned it off i heard a slight rattle wasnt really loud and not sure if it was a knocking sound. it could have been something just rattling im not sure. like i said im probably just being paranoid.

if it was a engine knock it would be making the noise the whole time right?

could be exhaust manifold studs as i just a a cat fitted so it was moved around a bit

im going to do a oil change today anyway what could the oil have to do with it tho as the oil has only done 2000kms but i dont like it so im changing it

i let it idle for about 15 mins gave it a couple of revs reved fine then i shut it down sounded like it came from under thebonnet but it didnt sound like a engine knock i dont think sounded like something knocking against something. not sure im just being paranoid i think. im going to change oil today and see how it goes then

ok just started it up and got the mrs to turn it off with my head under bonnet its a slight rattle coming from exhaust side so im assuming its either a stud or my front/dump pipe rattleing against something i will check it out closer as i need to do some work to the exhaust as when i fitted cat converter it shortened exhaust and it touches panhard rod in the rear unless it that rattling and the sound traveling up the exhaust

    • A 1.5 way is a 2 way. It is just a 2 way with a less aggressive ramp on overrun.
    • The ABS and/or TCS being missing/broken will not cause the engine to misbehave. It just casues CEL to come on and annoy you. The CEL is useless if it is always on, so you have to do the things you have to do to get rid of it, so it can be useful. Being a Stag ECU, then yes, it will not expect TCS to be present. But it will expect ABS to be present and working. You will need to either make the ABS CU talk to the ECU (don't ask me what that will take on an NA R34), and make sure the hardware is working....or, you just need to blank it out in Nistune. Do not persist with the stock ECU. You will just have problems. Gte it Nistuned. Start from there. DO YOU HAVE A BOOST SENSOR? The ECU's boost sensor that it. It is connected to the loom at the rear of the coil cover. Usually rides on the firewall on an R34, but is usually bolted down to a bracket along with all the other crap at the back of the coil cover when a Neo is dropped into another car. If you do not have it, the ECU will shit the bed. So, do you have one?
    • So sadly the fuel pump etc was not it. The pump and filter is new and it is still cutting around 4000 rpm. A read something about ABS/TCS (engine is from stagea and ECU too so no TCS) and i dont know for 100% that my car has ABS. It has ABS "cube" in engine bay but i dont think it works(or at least from my braking experience). Can be something like that?  I will be driving the car next week to Nistune tuner to properly see what is wrong...  
    • the Tomei LSD fluid with lsd kit. frustrated that it was shaking the car to crap and affecting everything else negatively, I pulled the diff last night, and removed the lsd carrier, could not find anything wrong, however it seem to be 100 locked up acceleration, and deacceleration, wondering if they sent me a 2 way not a 1.5??  either way I installed the stock open carrier back in place. test drove everything smooth as butter again. no shake, shutter, random, what felt like clutch slip and grab or drive shaft play, etc. something differently wrong in side the lsd. I might bother taking it apart (if possible) to figure out what's going on inside this carrier, as bought too long ago to return.  only draw back is its back to a one wheel wonder.
