Help! Turbo doesn't build boost until 6k!

[srblacks131]

whats the point of this

[kpc_0721]

Yea not sure I get what he is trying to tell us....just curious who makes that manifold?

[WDRacing]

The point is simple...holy huge turbo Batman!!!

[C-Kwik]

First thing I saw actually, was the crappy silicone job on the front cover. It's especially bad if it was done that poorly with the engine out of the car.

[Florida240sx]

You messing around or are you sayign it's not at full boost until 6k? which is what psi? Should be spooled before then...

[TheOne]

maybe you need to give me this setup, my ka will spool it faster!

[eazye2000]

Your turbo is bigger than mine. I'm jealous.

x2 on what kinda manifold.

[nelson8708]

he just wanted every one to see his massive turbo.

[onosqv]

I believe it was meant as a joke guys.

Bruinbear knows his stuff. Engine was meant to be functional, not pretty. I'm sure he'll clean it up before it goes back in the car. Last I talked w/ him, it's meant to be a road racing engine, but still spool fast enough for autox.

Are you really going w/ that turbo on the engine? What are the specs on the turbo & manifold? Don't be one of those guys who just posts a pic and expects everyone to know what's going on, haha.

p.s. looks like the compressor outlet is clocked the wrong way

* o yea, it's probably not spooling bcs there's no wastegate.

[bruinbear714]

Haha, relax guys, its a joke. Everyone in this forum is always serious... I'd just thought I'd show'd you guys a large turbo on the motor since not everyone gets to see that setup.

Manifold is a peak boost manifold, although it does seem like it positions the turbo a little higher than most manifolds I've worked with. Maybe it's the turbo, I don't know. I'll find out for sure when I put the actual turbo that I'm going to use on there... it's not going to be that large size, but it will be at the minimal a T3. Turbo in the picture is a GT35R series turbo.

Now getting the engine to put down 200rwhp before 3k RPM and have the torque not drop like a roller coaster past 5k is gonna be a little challenging...

[spooled240]

nos and a giant turbo like that will work like a charm if you want that windmill to spool haha

[nelson8708]

200whp before 3K......GT30 series for the win.

[Florida240sx]

crower cams for the torque drop fix

my new computer background

[spooled240]

lol lag is probably pretty bad on this setup especially with that huge tubular manifold

[nwmrkt]

is there a purpose to all those oval "holes" in the turbo inlet circling the the hole?

[spooled240]

i think it has something to do with the compressor surge at high boost. At first I thought it was just to make it look cool lol

[bruinbear714]

It looks cool, but the main purpose is for anti-surge. If you look at the compressor map, it basically moves the surge line to the left slightly.

[redhb240SXS13]

Think you could post a picture of the backside of the manifold and one from the top? Also could you take a measurement from the head to the center of the inlet flange? I'm making a manifold similar to this and I'm trying to get as close as possible to this manifold. Thanks

[sunnys14]

Thats a peakboost manifold

[turbo2nr]

eh its not that big.. my 62-1 t4 is equlivant.. makes full boost at 4500.. hits you like a truck when it spools tho..

[240sxmech]

to build boost you have to have motor in car and running not sitting on a stand looking at it turning it over with a ratchet...making the noise..lmfao...

[boker240]

in case anybody was wondering, that mani cost 750-800$$.

[WDRacing]

Big turbo's are fun at times...I had a big T4 on my Skyline and the 240...When boost hits it pulls your friggin teeth out. My power curve on the Skyline went from like 150 to over 400 in a very short amount of time. Wreaks havoc on traction...lol. Especially on the coral streets of Okinawa.

[spooled240]

^haha, i bet that big turbo with the rainy Okinawa weather was pretty fun eh?

My t3/t4 is looking pretty tiny compared to some of these turbos lol...big turbos on the freeway are crazy fun-all LAG is virtually nonexistent

Just curious, how much boost are you running turbo2nr?

[240sxmech]

hey WD when and why were you in okinawa i was there from dec01 to june02 Marine Corps we were at camp hansen.

[turbo2nr]

built the car for hi way im a big fan of wangan racing...

the car is on 8-9psi only because im still auto (5sp comming very soon) and i didnt get to install my emanage ultimate yet.. but its pleanty fast i take out evo/sti all day..

it is holding 12psi now b/c my wastegate is not working correctly, but its is stupid fast, its scary... i cant wait to daily it on 12psi..

[steve s14]

I have a gt35r and a peakboost manifold and it spools up pretty quick. Starts producing boost at a little under 2500 rpm and reaches 12psi at a little past 3200 rpm.Because the ka has torque, the car doesn't feel like there is a lot of lag. It kind of feels like a beefy sr.



You should be pretty happy with that setup as i am, and i can garantee you that it will build boost way before 6k if it's on a ka24de!

[turbo2nr]

t3 gt35r? its pretty quick is it ball bearing.... whats the a/r out back?

i might have to change to a 35r...
