It's funny Cus in person Nissan guys are nicer than the Honda cats But on this forum you guys are quick to attack the ones that don't now much. I knew I should have just waited for a response on ka-t.

Dude we are trying to help you, Read my post above.

The nissan people I know are really chill, but the thing about nissan folk is there are 10 of people like you for 1 that actually knows something.

Now I'm not saying being a noob that doesn't know anything is bad, but it gets god damn annoying when 10 people ask the same fucking question instead of taking FIVE MINUTES to find out some fucking answers.

Like I said from the very beginning. This sentence right here " I want 250whp and a Holset" you have failed.
and if you wanna spool at 2500rpm on a holset hx35, better drive in 4/5th gear everywhere

Holset isn't just one turbo. it's MANY different turbos with MANY different setups that spool at MANY different RPMS and flow MANY different HP ratings.

Look.. even the smallets holset is built for more power than you are asking. Holsets were never designed for Small displacement engines, and if you want to use that turbo and low boost, I guarantee you that your BIGASS holset on 5 psi would get ass raped by my 16G on 25psi

but of course, when you pop the hood it "looks" fast.

Also just gonna let you on a little secret dude, Holset + 2.5K rpm spooled is called fantasy land.

How are you going to tune it
what injectors do you plan to run?
wastegate and boost psi?
Intercooler with bpv?
oil lines to the turbo, tapping the oil pan / block?

If you plan on just "maxing" the stock injectors, just stop yourself right now and quit.

if you don't know how you are going to tune it ( which i really don't think you know since you didn't know what a wastegate is / does ) just stop yourself right now.

Here is what you need to do dude. Quit looking at cool pics of turbo's on the internet.
Take some time and RESEARCH, and LEARN everything you can about KA-T setups, NA to boost setups, AFR's in boost, TIMING, KNOCK, ETC...
because guess what, if you think you need a holset for 250whp "with room to grow" you have already failed. there are better turbos, that have better flow rates, better compressor maps, Quicker spooling Hotsides, the list just goes on.
And if you only care about spool time, Why don't you research what the hell causes quick spool or slower spools.. Or how hotsides affect Top HP? or anything for that matter.

You could have a HX35 that spools 6000RPM, or one that spools at like 3500 RPM. Go research and find out why.

If you want a holset cuz it's a big turbo and looks like you gots madzzz hp, Don't be surprised when you add a few holes in your block. Start investing in bus passes.

If you buy a turbo before you know what AFR means or what good AFR's are in boost, you have successfully became retarded.

THE earlier post you made made me upset but this one was indeed funny. Ofcouse I know what else I need.

I'm gonna run rx7 high impedience 550 injectors
I now know that I would need an external wastegate for the holset turbos ,
I'm gonna be getting it dyno tuned , I was gonna go with the Rom tunes , but nv are Dickks about smog so I wanna pass it.

3inch exhaust , I don't like the fart can look so something more

Gladman manifold.

Z32 maf

Ebay front mounts and pipes Cus we all know we can cheap out there.

I found the feed lines u need with the proper restrictor just don't remember the name.

Tial Bov.

Aem wideband

Boost gauge

Oil gauge

I'm gonna run an oil cooler

I WAS JUST HAVING TROUBLE DECIDING ON A TURBO THAT'S ALL.

I hope you realize you jumped to conclusions about my knowledge.

But I actually do read a lot.

I was just confusing my self researching so I figured ill ask. Thanks for all your help. And oh Yea FUK YOUUU

This thread needs a lock. OP, do some searching, all of this info is all over the net.

Yes, it does, but if he was to setup a proper twin scroll set, he would need two gates aswell, and still be out spooled by the ka's I tuned with hy35's.

Show me one shred of proof.

Please show me an HY35 that does this on a 2.0 liter:

Thank you for your help in this thread. I will look more into the hy35.

Ka motor is a 2.4. So your question is irrelevant.

You guys are all silly.

Project S13 · 03-20-2013, 08:48 PM

I did learn a lot tho.

OrangeVirus1 · 03-20-2013, 10:06 PM

since when is a KA24 a 2.0 liter

but you can't say XXX turbo spools this slow on a 2.0 liter, so it would spool the same on a 2.4 liter.

if that was the argument.

True

So out of all seriousness.

Which turbo do you guys think would I benefit from considering my temporary goal of 250whp. I know I have a lot to learn.

With your suggestions I will research further builds people have done and hopefully answer all my questions.

I know I started off asking the wrong questions. But I believe in only the stupid questions are the ones that go unanswered.

Ain't this the reason why forums got started for?

So if somebody could please help me out and not flame me.

OrangeVirus1 · 03-20-2013, 11:50 PM

S15 turbo will do the trick and shouldn't be very expensive.

or a 16G will get you there no problem.

If your dead set on a holset, get a HY35. HX35 is overkill

Thanks ill look into it.

About being set on a holset , i think this is were we bumped heads. I'm not set on it.I just wanted some information oh how this might turn out for me. I guess its to much for my stock rebuild motor.

I know a stock ka can handle 300 to 350 with a good tune.
I'm not trying to push it that much tho.

Just a mild build.

If a twin-scroll HX35 outspools an HY35 on a 2.0 liter, why would it NOT outspool it on a 2.4 liter?

To Project S13: You can get a T3 flanged 16G, I think this is probably better for your goals for simplicity sake if you already have the T3 open manifold. It should allow you to run your 250whp, and let you make another 100whp when you want to.

It's also brand new and pretty cheap here:

This is not a turbo motor. It is an NA motor converted to turbo, which is a hell lot different.

Which is exactly what is happening here; you want it to be true. You want people to tell that you can get more power and less / same mileage.

Well they did it. The problem is that it is not true, simple as that. The head is not designed for boost, which means lower efficiency, the cams are not designed for boost either, which means lower efficiency, and you need to lower compression ratio, which means lower efficiency.

Even if you make "the perfect tune", the engine will have lower efficiency, and thus more fuel consumption.

But you dont want to hear that, so that is the end of my contribution to your thread. I know you will be thinking "good riddance" once you read this, but i can tell you something : if you ever post again on this BBS asking why your engine does not work / blew / is fuel hungry, expect to see me posting "i told you, but you didnt want to read that".
