LSD and 4.1 final Drive

i couldn't afford the expensive aftermarket LSD for 325i E30 so i decided to get a 2nd hand factory LSD from other BMW Diff... after all its better than no LSD at all...

pick it up for $400AUD shipped...

also i got the 4.1 final drive.... its the cheapest way to get more performance over the stock dying engine... i got it for $250AUD shipped...


here are my rough 'oh so un-leet' calculation using the gear calculator to predicts the max speed differences every gear after the final drive been replaced...

AFM and the broken rubber boot

the car start idling funny.... so i prey open the AFM and fiddles with it... not that i know what i am doing but i do it by marking the original spot then move it to the right till it cannot idle and mark that as one end and turn it the other way until it idles smooth but cannot rev more than 2500rpm and mark it as the other end.... so the rough tune should be in between those 2 ends...

i know its not accurate but it works... hahaha
then just need to reseal the cover of the AFM PCB...




and the AFM rubber boot has leaks where it connects to the idle up causing the rough idle when the aircond on and stuck on traffic for hours... also it has alot of cracks where the clamps were...


so ordered a 2nd one from ebay for $40 and fix that right up... noticed that i used a electrical tape for temporary fix and it melts hahaha

Radiator Hose

on the way driving to bandung (city next to jakarta), one of the radiator hose split and coolant bursting out of creating a mist / fog on my windshield at around 150kmh...

anyway... i was lucky to have a lift from the car passing by to get dropped off to the nearest servo to get a new coolant, hi-temp sealant, duct tape and plumbers tape... walking back is a pain, as highway is one way... and i cant cross it to get a lift from the other side.... so i walked aroun 20 km but the good thing is the car has cool down when i got there.... so i did temporary fix it with plumbers tape, then sealant, then duct tape... and keep topping up the coolant while driving slowly (40-60kmh)

got the hose that i needed near bandung and replaced it right away....
