Special Turbine Housing T25-EWG-44, 44mm WG on T2x - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

***S14DB*** · 12-19-2008, 01:23 PM

Now you can run a 44mm external gate without having to get a special manifold on the T2x frame turbo's.

My question is would this hit the strut tower / wheel tub?

slider2828 · 12-19-2008, 01:31 PM

WHOLLY SHIET!!!!! GEEZUS.... how much and will it rub? Maybe I will swing by ATP on saturday. They are down the street from me and as if I can take a look at it and get measurements....

importdude · 12-19-2008, 01:37 PM

from the pics wouldnt it hit the block instead?

slider2828 · 12-19-2008, 01:39 PM

It faces out the other way...down and away from the block when you put it on.... Bottom mount of course...

BUT in the meantime, can someone measure like a Tial 44mm?

Sleepy240 · 12-19-2008, 01:41 PM

its tough to visualize but i think it would actually be closer to the strut tower side, and there's definitely some room to play with over that side
EDIT: My setup...

I ran out and did a quick measurement in the freezing cold just for the hell of it and the tial would be VERY close to the strut tower unless I'm visualizing it all wrong

Om1kron · 12-19-2008, 01:41 PM

looks cool but the placement is reeeeeeal iffy

s15specR · 12-19-2008, 01:41 PM

great....i'm very interested.......

slider2828 · 12-19-2008, 01:43 PM

Yah its REAL iffy... Cause it might even hit the tower/rails.... but Ima get measurements and pictures.... to see if it will fit... like I said if someone can measure a wastegate.... that would be best...

slider2828 · 12-19-2008, 01:45 PM

wait... don't you have to fit a dump pipe off the wastegate too?

joefresh · 12-19-2008, 01:45 PM

couldnt a short v-band runner be made for the wastegate? like so you could space and angle it differently? assuming it would hit, i think my idea would be an easy solution.

s15specR · 12-19-2008, 01:47 PM

question: if the 44mm WG wont fit is there any performance drawbacks to remote mounting the 44mm, basically running a tube from the vband on the housing to the wg thats mounted down the line or a convenient location or something ?

i'm considering using this as a replacement to the gt2871r internally wastgated, by keeping my tomei manifold setup with a gt3071/76 externally wastegated using this housing.

slider2828 · 12-19-2008, 01:49 PM

NVM I got the specs off tial....

http://www.tialmedia.com/documents/w3_tial_44_dim.pdf

So it looks like 5" tall with the added flange.... So see if we have 5 1/4" inches from the turbo turbine side...

The problem with that would be buying the special turbo housing would be pointless then??

Yes couldn't think of any reason why that wouldn't work

Also when the freezing rain stops I can run out and actually measure the WG

slider2828 · 12-19-2008, 01:50 PM

If you want it remote... I dunno if that will affect performance as it needs to fill up that chamber of extra "piping" before blow-off.... I dunno....

slider2828 · 12-19-2008, 01:51 PM

I think response on this would be freaking phenomenal....

my 2871r is external and i <3 it. I think the turbine housing is SICK if theres enough room

slider2828 · 12-19-2008, 01:53 PM

Yah mine is internal..... Actually probably 5 1/4 total clearance would be good enough....

Sleepy where did you get the manifold? From Aus? Only place I have seen it...

Sleepy240 · 12-19-2008, 01:54 PM

We switched back to the stock manifold and welded it on, it was so much easier that trying to make things fit. We just honed and cleaned out the runners in the stock manifold

slider2828 · 12-19-2008, 01:55 PM

Damn HKS only makes 50 and 60... I wanted the turkey call sound.... hahahah

No, you can find places that make 44mm to 44mm 90* adapters. You are bleeding off pressure. As long as it stays 44mm pipe you should be ok.

Sleepy240 · 12-19-2008, 01:59 PM

The problem I see with the whole vband thing is this housing is supposed to make things simpler and all you are doing by adding adapters etc is making things more complicated and expensive. Your probably better off sticking with the regular housing and mounting it elsewhere

Something like this might work?

s15specR · 12-19-2008, 02:07 PM

Hmmm I've been talking to steve shadows about the t2 GT30, this would be the best way to go and stay bottom mount. Now I'm between the 71 and the 76,

no this approach helps eliminate the boost creeping internal gates on most t2 platforms, however in the end it will be cheaper than going top mount in my case since I keep all my components except the turbo.

I can't recall it right now but toyota did this on one of there famous old school race cars and had great results...

slider2828 · 12-19-2008, 02:12 PM

or a remote pipe like this? 3.00" 90 V-Band Pipe - Short Leg: atpturbo.com

Doesn't ext. wastegates give more response too?

s15specR · 12-19-2008, 02:40 PM

44mm wastegate port is about 1.75" in diameter

slider2828 · 12-19-2008, 02:45 PM

yah so maybe atp has something like that hopefully.... or have luke weld up something to point it downwards....

memphiss13 · 12-20-2008, 12:30 AM

i think this might solve the clearance problem. The one on the right is a new wastegate from tial. Its alot shorter. The only thing I'm not sure of is if it uses the same size v-band flange as the v44.

Description from Tial:

TiAL will be replacing the F38 wastegate with the new MV-S wastegate. Small was on our mind when we developed this new ultra compact wastegate. It stands only 3.7" in height vs the current F38 which is 4.85" Other features include 3 bottom pressure ports for easy install and a top mount pressure port that can be rotated 6 different ways. No more bolts or gaskets and all configurations are leaded fuel safe. we also altered the way the diaphragm sits so it is virtually impossible to pinch. A late fall release date is scheduled.

usdm180sx · 12-20-2008, 08:38 AM

This is awesome news. No more boost spike due to a weak ass internal wg setup!
