Changing the oil

Hey Guys

im sure you all have been asked this more then 100 times but i did searching and didnt find anything.
so questions is how much oil do i put in the SR20det and what filter can i change the old one with?

also what oil would you recommend? I used 5w50 full synth in my GTR so im not sure what i should put with the SR.

thanks

i use 5w50 in my sr. because its turbo its better to go with a thinner oil. it takes about 4 litres. and the oil filter number is ph4386 (fram) for the s13 im not sure about the s14 sr.

thanks
