GT2871 installation - DIY

[Def]

Again with the teflon tape on a fitting that doesn't need it. Hope that stuff doesn't end up in your CHRA, or you'll smoke your new turbo...

Nice writeup! You should have went the extra mile and upgraded the elbow though. The 2871r needs it! You'll see what I mean when you replace the elbow. Again, nice write up

Great write up! i just finished the same setup except I used the Megan Turbo elbow! HOLY F*CK is the oil return a pain! i tried to use the T25 oil return. Even with bending and heating, it still wouldn't line up the same. I tried to fab a new line and it turned out worse! Good DIY! I would love to see a section on the Tech about all DIY installs

+1 for a awesome guy!!! i wish i can do stuff like that right now =( running stock KA =(

but this is something i can look at in the near future in like 2 years or so lmao

good job !! keep up the good work thanks for willing to help me out with my car problems as well!

[SoguRacing]

i think they have one in the Fabrication section. thanks. the diy isn't that in dept but just having everything laid out makes it that much easier. i'm switching elbows soon. haha. thanks for the rep

[Flybert]

The part I'm confused about is how it took you 10 hours.

[xplicit240]

have you gotten a down pipe already?

[NSR250]

nice write up. I did a similar 2871 upgrade

[((sr)) kelly]

so it wont stall
that looks to be a synchronic bov
they are fully open at idle
the car would not run if it were not recirculated

[SoguRacing]

the recirc has to do with the maf sensor and the bov releasing metered air after boosting. if it were to vent to atmosphere the car would run rich for a split second and bogg down or even stall. recirc keeps this from happening by allowing that metered air to enter back into the system keeping it closed loop instead of open to atmosphere.

by the way, i took off the oil line and cleansed it of the teflon tape. still haven't started car yet so everything is in check. also on the way is a megan elbow that will be installed shortly along with my test pipe.

[driftage240]

Go to any autozone and ask them for this hose S4572 it works wonderful when recirculating....
here's a pic of the hose


and how its suppose to look like after install


just thought id help....good job on the diy..

Thanks man! looks much cleaner than recirculator haha.

Looks good, how are you tuning it?

[SoguRacing]

i have a power fc which i will be getting tuned as soon as i drop in my new injectors and z32 maf.

[aznrib]

can you post up a video or a sound clip for the synapse bov?

very nice.. should be fun!

[SoguRacing]

there videos on youtube where people have used the synapse bov. check it out. plus, my car isn't running yet.

[rps13sr20det]

I really wish I would have read this thread a week ago. Finally I had my turbo bolted up to find out later that the T25 oil return won't work...even with heating and bending. I need to get one ASAP in Canada

[SoguRacing]

you can buy the oil line separate and install it from under the car, its awkward but i did it with my t28 to get the teflon tape off. i just hope you dont have arthritis and just use a small mirror to look at the fitting. good luck. i think they're around 60 bucks.


by the way i added some stuff to the initial page

[SoguRacing]

haha i hope. My car has been sitting in the driveway collecting dust for the past month. still need, oil change, and undented oil pan if anybody has one that is local. i have a s14 waterneck or a pulley set for the redtop if you want to trade. hit me up

Thanks aNskY

[drift into a curb]

+1 for Daniel. This rocks.

[SoguRacing]

thanks man, there's more to come. Have fun in asia!

[s14unimog]

nice work and good job on posting a lot of pictures. As for the teflon tape issue, its really not that big of a deal, your turbo will be fine. If you put the tape on correctly then it wouldn't be on the inside of the turbo and its sure as hell not going to work its way in there. But like everyone said its true you didn't need it.

Props on the turbo upgrade, I've still got my finger over the "buy now" button for mine. Somebody slap my hand!

[SoguRacing]

haha Just do it. Yea, i like to post pictures, helps me out and others too. I'll soon be getting my car tuned and i'll post the dyno. JUST CLICK IT!!!

[SoguRacing]

Ok guys!! i got everything installed today and started up and there is some smoking around the turbo/manifold area. can't locate where it is coming from but as soon as i saw it i shut off the car. do i need to somehow prime the turbo lines (oil and coolant)? any ideas? has this happened to any of you?

[Sileighty_85]

the smoking is from your greasy little hands touching every thing.

the heat is just burning it off it'll go away after awhile

well if ya wanted to prime it first ya should have pulled the CAS and turned it over for a little bit

[surge s14]

maybe a leak in one of the oil lines?

there is only one line and its clean as a whistle. A clean whistle that is.

I suppose it could be from my dirty hands but the turbo was pretty clean when i installed it.

So this is normal for most peeps?
