Nissan 200sx S13 CA18 and SR20 mpg?

[tom163]

Looking for s13 owners or anyone who had experience with these to give me a rough idea on fuel economy on either the CA18 or SR20 engines when going steady off boost etc....i've been told about 30 mpg and 30+mpg when on runs etc etc.

Cheers

Only if standard, the SR20 is slightly better generally

[tom163]

Interesting thanks mate....would have though the SR being a 2.0 would be worse lol.

Both engines are good and can show mpg in the 30's. The sr is more modern and slightly more powerful in standard trim.

My s14 with an sr can see nearly 30mpg on a run butane is running significantly more power than standard.

Edit: I'm sure you're aware but the uk s13 didn't have the sr fitted. If you find one it'll either be a converted uk car or an imported 180sx.

Just to add,both engines are much more economical when remapped for higher power, my sr20det easily did 5 mpg more when cruising at 280bhp than at 200

In general though the sr is a more economical engine in my experience due to it being newer and having vvt etc...

The man speaketh the truth power upped and matching remap

generally - keep off boost and they return reasonable MPG - well............. reasonable for a 2lt 1990's car.

Basically try to get an SR20 engined one as the CA18 is a bit of a dog of an engine compared to the SR and RB lines.

Having 7 months ago sold my pulsar gtir (sr20) and bought an s13 with the ca engine , to my fairly short experience the ca is way way better on fuel and seem's more reliable too .

Aswell it makes a better noise :-)

4wd vs 2wd probably makes a bigger difference in that case!

I owned a CA18 200SX for a couple of year a number of year ago. Used to get high 20s overall, and would break into the low 30s on a long/easy runs.

I have a 180SX with the SR20DET. Stage 1a, so Horsham Developments chip, intercooler, spark plugs, higher boost on the standard turbo.
My best recorded is 37mpg going from London up to North Yorkshire.

So on the motorway, yeah, they're pretty reasonable on fuel, especially once remapped not to run so rich.

Yep Horsham chip really helps the overall MAP. I've never done tank to tank comparison as I've always pootled, had a blast, then pootled back, but always had a feeling that pootling was mid to high 30's, but with no real evedence to back it up.
