I have everything I need for the turbo swap on my LNF besides the turbo, but only because I can't decide... My goal is to make 400-425 whp, without maxing out the turbo. The reason I am thinking a 70AR is because I want the power to be as useable as possible. I am trying to avoid tire fire from 2500rpm and up. I just need some advice on which way to go! thanks in advance guys.

 

if you only want 400 then the 256 will be PLENTY.

 

I figured. I just wanted to check with the masses. There is a few people telling me to just go big to save myself some room if I ever wanna go higher.

 

I believe you can get a billet wheel for the s259 so it would probably spool as fast or faster than the s256. I used to have the s256et and it was my favorite turbo out of all the ones I've had.

 

I'm not so much worried about the spool time so much as totally maxing out the 256 to get to 400whp... I'm fine with lag, i'm used to boosted Hondas. That's why I plan on getting the biggest hotside of what is available through ZZP.

 

Problem is, these aren't Hondas and cant rev to 10 million RPM. Your are probably best off with the S256et. It's got plenty of room for what you want.

 

LOL as i feel like a retard in the ecotec world. What is the max the 256 can put down?

 

The S256ET can put down upwards of 550whp efficiently. I think ZZP has put down over 600 with it though. Thats the .55 exhaust a/r as well. I'd stick with the smaller exhaust since you have an LNF. We can only rev to around 7500 before the cam phasers stop working.

 

256ext .55a/r exhaust, small turbine wheel.

 

Not for long

 

I'm sure the s256et will be just fine for the power you want

 

you can hit 400 even with an s252. dont understand why you want an even bigger turbo unless your going for bigger power later.

 

s256et. i'm hitting 19psi at 3700rpm

 

Well hurry up and develop those phasers! I'll be a test car!

 

Any update on the lnf cam phasers?

 

not that im tracking

 

If I wanted about 450-500whp now while on stock motor(lnf) with cams/springs, BUT want to be able to hit 600-650whp later after motor build ect, would the s256et .55 be able to hit over 600whp with build motor ect or should I look into a s259et .55 so I can have that power available later on when I am built. Basically, pros vs cons of 256 vs 259.

 

This statement is not true whatsoever. Don't believe the "billet wheel hype"

Just an fyi

 

What charge piping and downpipe did everyone run with the 256et?

 

S256et will not hit 600.

 

Probably zzps...

 

i would stick to a .63ar max... .55 are will come on fast

i have a pte 5558 bb with a .63ar turbine housing and the power comes on perfect. stock clutch holding on 23 psi havent gotten it on the rollers yet tho,
