The latest motor, 375 bhp, 380lb/ft. + family toys

The engines are not weak. Bad mapping and bad fuel and low maintenance kills these. Thats all. lol

Aye needs looking after for sho'. Bottom ends have never been a strong point on 200SX's

Might be mistaken but apparently the spray bars on the camshaft are a bit gash, which can lead to scoring, and the swarf gets into the big ends and shags them.

Which leads to this:

Upon inspection we found swarf in the oil pickup, and a spun bearing.

There was also a fair amount of scoring on one of the cam shafts in this area:

SR20 is a very solid motor, that stuff only happens when it isn't serviced properly. If you want real bottom end weakness then try a CA18DET out for size.

Agree to an extent although SR20 bottom end problems aren't exactly a rarity. It would be narrow minded to automatically attribute all these to poor care.

Most of them are though, at least most of them on sxoc are due to that or incorrect modificaiton. I've not really seen many engines on there go bang for no reason, it's certainly not a common thing.
 
from memory the biggest problem the engines had was oil starvation due to the clogging of the oil feeds, thus the general feeling that "bad servicing" was what caused the engines to die - A regular oil change may well keep the oil clean and less likely to block causeing oil starvation

oil change interval on these is 3000 miles, how many do you think miss oil changes? :p
 
They've actually done an oil analysis, pretty sure the outcome was that if you use the correct oil, 3k is simply ott as the oil does not degrade. Most people opt for around 6k.

Well there we go. Nissan say 3k, people then make up their own intervals at double that and then moan when the engine gives up.

No they don't. According to my service book Nissan say 6k. Some people just change it sooner as it's an easy job but a modern synth oil would probably last even longer. I prefer to do it at 3k and use a cheaper semi synth oil.

As Gribs has said already, the normal service interval is 6k miles according to the original service book which I have. I can see why some think it is 3k miles because on the page where it says "turbo charged petrol and all diesels vehicles travelling less than 18k miles" it says the normal service interval is 6k miles but on the bottom of the page it gives the service schedule for a 3k mile interval aswell but that it only for the F23 Cabstar.

I suggest you get a clue. :p Fully synthetic oil and around 6k has proven to be fine. A lot of the people have done this and have had no issues, using the right oil is the key, as well as changing according to how the car is driven.

I do have a clue. What actually is true here is that Nissan state 3k changes, that's a fact. I would quote a page from the service manual but frankly I can't be bothered explaining myself, you can read for yourselves.

I have quoted it from the service manual on post 76. The 3k mile service interval is for the F23 Cabstar diesel. :confused:
 
3 or 6k is going to vary on the car itself to some extent I think, the more emissions placed into the oil the quicker it degrades.
Probably also varys how its used and the season, mostly city trips and 3k is about right I bet but if its used the way it should be and put to proper use every day then it'd be running more efficiently also. I would not take the manual as a bible either way

Anyway looks good enough to put darth vader to shame but I wonder how black or white alloys would go
