What's the differences between the s259 extended tip and the s257 sxe turbos?

Devin86

Spools like a 256 power of a 259

Canadia

So get the 257

They both flow the same? How much do they flow as in lbs/min

is the 257 water cooled? if so, where would I get the lines for it to work on lnf? trying to email ottp is like talking to a brick wall

Almost no JB turbos are water cooled. The 257sxe spools faster and flows the same as a cast wheel s259, approx 65lb/min

It's only oil cooled.

You would make lines though if it was water. It is pretty easy.

nice. buying all the turbo kit parts from zzp with this turbo is quite a but cheaper than getting their kit with either turbo they sell with the kit. interesting.

is the lnf return coolant port 1/4 npt? seems like the plug I have that size fits it. if not, what is it?

tomj77

iTrader: (2)

well I'm happy I found a cheaper way to do this. nice. definitely going this way. price is actually a little more expensive than the bigger zfr at zzp buying all the parts seperatly with the s257. I know there are some things I'm missing or will need modding , like intake. hopefully I can mod the k&n intake to work with that turbo. if not, I guess ill get one from zzp.

Pretty sure the coolant bolts aren't NPT fittings, NPT gets larger (tapered) the further from the tip you go which makes them great at self sealing. Afraid I don't know what size that is though.

Well I know they 1/4 inch, cause 1/4 inch plug fits in there. Just normal thread I guess. I'll take it to fastnal and they will tell me what it is. I do have a fitting that will work for the feed port. Nice and easy thanks for the help guys.

Shame tom, Justin Paul Calvin just sold his whole 257 setup for like $2200. He really struggled with traction on his Lnf. Think he made 480whp with it and may have gotten more.

Yes they are a metric thread size

The compressor inlet on this turbo is 3.5". Running a k&n thats a 2.25" isnt worth it

The one on the thermostat housing is 1/2NPT

The one on the front of the head is m14x1.5

Excellent , thanks guys. I guess I'll have to get the zzp intake then or something else. Guess I'll be selling my stuff

blueLNFftw

iTrader: (16)

Any bigger intake will do.

1/4 not 1/2 half is huge

tomj77

iTrader: (2)

so they are actually both 14mm x 1.5. I find to plug the collant return an new oil drain bolt works perfectly.

Interesting.
I have a 1/2 NPT for mine.

What is yours; LDK?

tomj77

iTrader: (2)

I don't have my ldk yet but my lnf is 1/4 or 14mm

tomj77

iTrader: (2)
