Me and him have hands down the best tuner in America.

He's been through every turbo between 2871 to 42r lol

stock motor, and pushes 500whp..

that is crazy. how often is it driven? daily?

[zombiewolf513]

Once

[koukistylejdm]

ok someone want to speculate iam curious what it should make....

iam getting a rebuilt sr at the moment with...

86.5 bore stock compression pistons
eagle rods
head decked
cometic head gasket
evry arp studs
tomei poncams with valve springs
gtx2867
740cc's
stock intake mani
stock exhaust mani
iam going to push it 50/50 c16/91 oct
something like 24psi

any idea yet on the gtx?

ive been pushing 350whp on dynapak last year on a fully stock sr with the gt2871 at 23 psi ( with the same fuel mix)

[Seraphim38]

need to specify which exhaust housing AR for someone to give an educated guess. Otherwise, I am going to say maybe 410-420 depending on how hard the tune is pushed.

[cotbu]

Which version of the 2871r did you have? I say 405-415
Unless you do a re tune, 350 at 23psi? says 52trim, bad tune or beat engine.

Make a build thread and put it in your siggy.

[sr20det_510]

ok you guys think that mani will break?

[zombiewolf513]

maybe, what brand

[sr20det_510]

megan mani look at thickness that thing is heavy

[zombiewolf513]

Those things crack all the time. Just use a stock manifold that has been extrude honed, like CodyAce. I've got one for $40 shipped if you want one.

[sr20det_510]

were do they crack from i want to do a top mout

[sr20det_510]

and for the 510 you pretty much have to run a top mount setup lol

[zombiewolf513]

ive never had one. I stopped buying garbage a while ago.

[sr20det_510]

lol but like i said i need to run a top mount

[zombiewolf513]

You mentioned that.

That SR is not at all like a virgin; more like a two dollar crack-whore that's been fucked half to death and sleeping in a dumpster for the past 15 years.



Also, there's a little edit button down in the corner. Edit your posts instead of double posting.---------------------------------------------------------\/

[801nismo104]

i used a no name manifold for over 3 years with no problems. if you don't have the funds for a new one just use it until it cracks. i would recommend a mazworx or doc race mani though

DOC is legit. Quality welds and materials. Mine isn't driving yet, and I've gotten compliments on it by every single person that has seen it so far, too. es very nice

[sr20det_510]

ok i guess i wont argue

i think they crack because cars are low. the down pipe hits something like a speed bump, and it pushes up the whole exhaust side, and since the mani is already hot, it ends up cracking it.

Get a DOC, quality manifold with real collector! I hit 18lbs around 3700rpm with 2860rs w/ t3 .63AR housing. Collector makes a big difference with spool.

[jamg]

damn, that one looks sick.

expensive though.

[Seraphim38]

bottom mount T3 2860? Well, that's different.

My old GT2871R .64 setup would hit full boost and spin the tires at 3,500.

Slow spool for a .63 AR 60mm turbo. Very very slow.
