I have the 2871 and tubbed engine bay, worried about space for the intake... Filter might have to sit behind the radiatior along the frame rail. Im guessing everyone is using a custom made intake pipe?

HKS Super Suction kit. Fitment was damn near perfect.

23 psi all day long
with stock extermal waste gate
anybody can tol me why,i use to run 15 psi and i change some timing cells because i have to much knock 130
and now im run 23 psi with 28 knock.

why people say you have to change the waste gate if you want more the 15 psi and i run 23 psi with no problem

cotbu · 05-28-2013, 04:43 PM

Pictures are worth better words! Post the graph! I don't feel like picking apart you postusses!

Stock external gate?

Not going to comment on the rest of this as its hard to understand and I may be translating it wrong.

jr_ss · 05-28-2013, 04:59 PM

There's no stock external gate, so I'm not sure why you're making that claim.

KA240SX808 · 05-28-2013, 06:15 PM

Pics of said OEM External WG?

sorry internal waste gate

WhiteS12+1 · 06-01-2013, 10:06 PM

Mine put down 352 hp today on a dyno dynamics. .64 with a built head,S3's and cleaned up Freddy manifold, Cody ace external setup, on a pfc at 19 psi. Will post dyno chart once received from the shop. What do you guys think?

KA240SX808 · 06-02-2013, 12:27 AM

On a Dyno Dynamics, that sounds like a healthy setup/tune.

Since your head is built you should try taking it to 8k, looks like it might be nice and flat until then.

JohnnyDrfiter22 · 06-02-2013, 01:13 AM

I can now join this thread.....

My setup
Isis Turbo equivalent to a 2871
PBM Mid mount
Sard 550CC injectors
Greddy IM, Tomei TB
AEM V2
at 16lbs Made 308WHP and 237 ft/lbs
Tuned by Matt Waldin @ Import Intelligence

He said he was highly impressed how much I made and the power curve and torque curve but just climb very smoothly. I didnt want a dyno queen just a nice safe tune.

Sounds like my setup but a little different.
GT2871r
Greddy IC Mount
Tomei 550cc Injector
Greddy IM
PFC
But leaky BOV and when it was tuned the inlet temps were 118F.
I swear there something wrong with my turbo.
this was tuned with 16.8lbs

sil14zenki · 06-11-2013, 03:58 PM

for those of you guys running exwg set ups. where are you hooking up your boost source?
i've searched and seen most people tap into the hotpipe. can't i just tap into the outlet pipe as its cast aluminum and a little stronger? thnx in advance

4-20sx · 06-11-2013, 04:20 PM

I tapped my hot pipe.... Worked great!

What outlet pipe are you talking about?

sil14zenki · 06-11-2013, 04:41 PM

compressor outlet.

EsChassisLove · 06-11-2013, 06:35 PM

I tapped the compressor outlet also. Best place to put it. Nobody can see it.

Hey man, chase down those boost leaks.
Your numbers are kinda low for that set up i feel.
oh and i noticed ur graph said aug/2012, so the summer IAT's might not be that bad

jaysgottaredtop · 06-16-2013, 10:07 AM

I'm getting ready to put in my built SR with a 2871r (.64 housing). The head has BC springs and retainers. The only things left to order are cams.

I was originally planning to go with JWT S3s, but my aftermarket springs/retainers should easily be fair game for S4s or even C1s.

Question: Would the extra lift/duration of the S4s or C1s be worth using? Presumably I'd trade off low end for high end... but with a T2-flanged turbo would the gains even be worthwhile? Would there be any noticeable gains at all?

Car is used for drift events, occasional track events, and reliable street driving. Aiming for a healthy 380+ if possible, but I'm more interested in a useable powerband than peak numbers.

codyace · 06-16-2013, 10:50 AM

You need to see where your RPM's are going to be most often. If you're in need of the 3000-6000 grunt, go S3. If you're going to go with the 5000-8000 run most of the time, I'd go S4.

With that said, I'll be swapping in S4's into my car soon to see the difference. After many years I'm gonna give them a try to see.

jewlz · 06-17-2013, 11:45 PM

Cody why not try the s4HL?

If buying them the S3 or S4 brand new from JWT, then I would strongly suggest the HL variants

However in my case a very good friend of mine has S4's that I'll be able to (almost) indefinitely borrow.

***S14DB*** · 06-18-2013, 05:26 PM

Do the HL's work with VTC?

EsChassisLove · 06-18-2013, 05:32 PM

I want to go HLs so bad.

S4HL.

Who wants my S3s? Lol. 3000 miles on them.

jaysgottaredtop · 06-18-2013, 05:44 PM

^ me! assuming i don't buy S3HLs new, haha

This is spot on! I have/had the s4's and 5k-8k is pretty crazy

but keep in mind, turbo was gt3071

That I do not know. IN that same regard it wouldn't be a major concern for me if it didn't as I'm always above the VTC threshold as it is.

KA240SX808 · 06-18-2013, 07:47 PM

I would belive so because on the Cam Card is says available for FWD, RWD & VTC.

Also Cody, can't you extend the VTC range? Or would it not be beneficial?

sftmb · 07-02-2013, 05:38 PM

Are there any dyno's/info on guys running the S3HL's? I was originally going to go with the standard S3 setup with stock valvetrain, but found out about these HL's today. It seems like with 11.5mm lift and 260 duration they should be fine still.

FWIW, I'll be running the gtx2867 .64 with a DocRace mani and Tial MVS.

Silvi · 07-08-2013, 07:59 PM

I have a good deal for 2871 T3 AR63 version.
Is it swappable with S15 back AR?

GuardianLlama · 07-08-2013, 08:48 PM

I posted this a while back, but this is s3HL vs stock with a 2871r
