Legit GT40R Twinscroll?

[holeinmypocket]

found this locally should i pick it up...the price is a steal
supposingly a GT4082 T4 Twinscroll...don't know any details on a/r or anything though


NEW PICS

[nighthawk358]

doo ettt

[holeinmypocket]

on a ms3 though ...lol
yeah found it for a bargain just don't wanna get ripped off buying a knock off

[zx2man]

Wonder when the fucker spools lol....but when it does spool, you would absolutly fuckin know it.

[nighthawk358]

if you plan on running the gt40r, you should look into the high rpm big turbo build thread so you can maximize the potential on that huge turbo by revving at least to 7.5k rpm

[holeinmypocket]

I know lag would be crazy put once it spools ...we need streetunitmark to chime in..for the price I should still get it...even if I throw it on or not

[holeinmypocket]

turns out its a GT4082...hopefully I can fit this under the hood

[bmylez]

Move battery and do custom sidemount turbo manifold. Revving high is gonna be your main problem.

Ha I don't think a Ms3 with that turbo would make near the same power or move out as fast as that evo.

OP it's not worth it. Remember you want something that spools fast since you don't have alot of rpm to play with. Go smaller and have a more useful power band.

Also whats the price that will tell you if it's a knock off or not. My boy just picked up a new one for 1250 so if that used going for 800 yeah sure. 600 maybe, 350 its garbage.

[holeinmypocket]

watched some of those vids but those evos are revving pretty high i think i saw one that revs to 8.3K and another one short shifting at 7.5K...I just don't know if i could take full advantage of this turbo only revving to at most 6.7K

[nighthawk358]

nigga run that turbo to 7.5k

[holeinmypocket]

what's it gonna take to rev to 7.5K...headwork?...cams...?

[bmylez]

Valve train work at the very least.

JUST DO IT!

Im revn to 7500-7600rpm. so far this is what i know- U will need to balance ur bottom end with forged internals. You will need valve retainers, valve springs ( have a look at supertech kits). DCR VVT for the heavier valve springs, standard ones will break.

I would suggest oversize pistons at least 40 thou(1mm) this will help with your spool time down low and bottom end torque. Look at a Manifold with shortest length piping for earlier spool times.

DOOOEETTT get it

[zx2man]

I agree with darky...the ms3 is not a evo...we just dont have that powerband...KUDOS and huge props to guys like Wilksy who want to see what it takes to open up the rev range on this car, that gets my full respect.

I dont know what your budget is, or your ultimate goal for this car, but if your trying to keep it fairly real, go with a turbo that will work within this cars powerband.....trying to do other-wise might lead into ALOT of future headaches,time and alot of money...This car is already imo one of the hardest cars to mod for big power to begin with, nevermind trying to go above and beyond and start experiementing which who knows where it will go. I leave that for tuner companies who have the experience and money and time for huge projects like that, not your common day man.

Just my 2cents....Goodluck with whatever you choose

[holeinmypocket]

ok...this thing is a beast went and picked it up today drove 3 and a half hours to pick this bad boy up...took some pics while i took my kids to the park...that cup that i use for comparision is 32 ounces...It's a T4 Twinscroll and the v-band on the hotside is 3 3/4 inner diameter...this was a brand new turbo for less then half the price of retail found on craigslist (some what locally)...








I want a sidemount manifold like this if it doesn't fit between the block and the firewall

[SFWD 1934]

That turbo is a decent turbo. The turbo only has a 58mm inducer, so it is not that large. The exhaust is 77mm. Flows about 55lbs/min. Anything after about 26lbs is just hot air. Should be a good 450-500WHP at 20psi turbo for you.

You're gonna have a really really tough time fitting it behind the motor. I vote side mount. Good luck spooling it, man...

[holeinmypocket]

Spool it w nitrous...i got pauter rods y not

[aaronc7]

help IDing a turbo

here you go. specs match up this.

GT3776

TurboByGarrett.com - Catalog

or just take it apart and measure yourself

[turd burglar]

you might be able to fit it behind the block, but you are gonna run into an issue when it comes to making a downpipe clear the alternator as that things exhaust leg looks pretty ridiculous lol sooooo it looks like side mount it is!

[holeinmypocket]

fyhn 2k on a manifold here I come....oh wait fuck my life 2k...i wanna do it

[SFWD 1934]

Here. Good thing I do not throw stuff away.

[bmylez]

I love how it says "Displacement: 3.5L - 5.0L"....lulz...

I really think you should include beefier valve guides, valve seats, valve springs, and DCR VVT in your build. Run 7500rpm and the car will actually have some semblance of a power band (without nitrous).

[holeinmypocket]

Yeah but who makes all of the hard parts for a cylinder head for our cars? It's gonna have to be a lot of custom parts.....unless u guys got direct links to these

There is a thread in the BT section called "Big turbo and high RPM" I believe. The guy is from Australia, but he managed to get better valve train components. The DCR VVT is readily available and is the first step in revving high. Get in touch with that guy on total cost of the head parts.

thanks for the info...i will check into it...sigh more money to throw away at this car

[Monotonous ONE]

in for results...this is gonna be awesometastic

By this summer Supertech will have a valve train assembly for the MZR motor!

my friend, i hope your are correct. is there anyway they can chime in on this?

[SFWD 1934]

I am sponsored by them for my Outlaw car (Honda). I was asking them about the parts they have for the 2.3L Duratec motor, and they told me just wait, the MZR stuff is coming.

Supertech answered all my emails quickly. Good luck with it, whats your RPM goal?
