Which should I go with GTX2863, 2530, or 2860-5

[Piggaz]

Put a single on it.

[Dose Pipe Sutututu]

Or do what the Japs did, run dual plenums, dual ICs.

That should help reduce the turbos "fighting" each other.

It's just like when you see two cocks in one box.. doesn't work too well, you need one in the pink and the other in the stink so noone is fighting for it.

My stance has been 1x hole 1x goal, ie single turbo!

[No Crust Racing]

I have no idea what those numbers mean.

The path ot successfully running twins has been shown numerous times. 

 

Have a sensible power goal, mild cams at the most, Twin Turbo pipe divider mod, good dumps/front pipe combo and don't use -5s if you value response. 

-9s with all of those bits will get you a healthy figure for the street. 

If you need the better high end power of -5s on a 2.6L and still want response, put a twin scroll single on it. 

What is your power goal?

So what turbine is your rebuilt turbos running? Still the 2510 turbine or full GTX2863 core in HKS housings?

[djvoodoo]

Havent been in this thread for a while [emoji16]. I think he had the full gtx core into the housing, where i just had the comp wheels.

[Dose Pipe Sutututu]

And it was a fail like everyone else has predicted 

[sneakey pete]

Was going to say i get more boost sooner with my EFR but its got .2L and 260x11 cams behind it.

Glad i didnt install these on mine now. Will be interested seeing how old mate whos got them goes using the stock port shrouded front covers.

[Mick_o]

Bet ya glad ya listened now Pete? Twins in the bin single for the win ?

Wouldn't matter what cams or capacity the EFR still woulda knocked the snot out of those frankenfart twins.

At ANY power level!

If you're serious then you're going to need a very good single turbo, like an EFR, with proper twin scroll setup.

The only way you're getting that goal with twins is with a huge displacement increase.

The single turbo swap will be cheaper.

You're also going to want a few other mods so it can live for more than a few Dyno runs.

When are -5s spooling? Can I get 600whp from them?

Is there a reason why you need to stay twins? Personal reason? Law enforcement? Because that's how Nissan wanted it? GTR's "must" have twins?

he was like Paul Version 1.0, twins, lag was life. Paul Version 2.0 is about usable power, better heat management and less homosexuality.

what is better to install Borg Warner S257 or -5s?

BW EFR 8374/1.05.

Be on 500 rpm earlier than -5's and make more power everywhere.

[Mick_o]

5s are f**ken shit! So are journal bearing turbos.

As above 8374 is an absolute beast of a turbo! 

If you want good power and response forget the twins! 

If you need the stock look so you dont get busted sure stay twins. But thats the ONLY reason to keep them!

[Dose Pipe Sutututu]

A journal bearing twin scroll single turbo, I would dare say would perform better than a set of twins that produce like for like power output.

100% ?

Will only suck a dick between gears not everywhere like the 5s do!
