Pulsar GTX2867R meets Kraken Low Mount
I posted this in my build thread but figured I would put it here as well. Recently my GTX2860 that I kinda slapped together last year with a Garrett CHRA and a Arashi compressor wheel and housing bit the dust. I needed to get back on the road as cheap as possible to I bought a Pulsar GTX2867, normally I would only use Garrett but its $1500 and the Pulsar was 1/3 that cost. The Pulsar is a .86 a/r turbine and a larger compressor so its spooling slower than my GTX2860 but its still hitting right around 4k which is honestly just fine. Getting into the powerband is easy with this turbo its way more linear. The 2860 hits HARD in the midrange and then loses steam up top. I was running 25psi tapering to 22.5 by redline on the 2860 to achieve the same power the 2867 is with 18psi tapering to 21psi to redline. I now have an EBC instead of the MBC I was using before. So I chose to bring the boost on smooth to keep the car more linear instead of hitting like a ton of bricks. I want to turn it up more but I dont want to break anything before the gap trip.

You "should" be able to use your old turbo housing from the Garrett. Might be able to get a little bit faster spool.
I am hoping to grab a few Pulsar turbo's in the future. I am also a dealer.

Yea, but my bb cartridge literally exploded and both wheels got catastrophic damage so the housing may not be useable. And it's already on the car and the spool isn't that bad so I'll probably just run it as is. I have 300 miles since the incident and I still don't trust the engine. It saw a lot of metal flakes in the oil after the turbo blew. It's still got great oil pressure but only time will tell.

See now seeing this makes me want to get this turbo. I was worried about it being super laggy but my chins T3 is making 20psi at 5krpm. This thing is a whole 1000rpm sooner than that lol. Granted my VVT isn’t working atm so that’s greatly contributing to my lag. Thanks for posting! Keep us updated on the longevity and reliability of this thing!

Little update I did another VD pull the other day just to check on the car. It's running up to 26psi now, the total hp# isn't much higher but there is a lot more tq. I think in order to make more power up top I need ethanol so I can run more timing, but I'm happy where the car is at. 93% injector duty now so this is about as much as I can ask of it.

I have broken one 6 speed that was from an nb1. It was actually back over two years ago when I had a 2560 making 296whp/280ftlb. I flat shifted it into 4th and grenaded it. Since then I got a nb2 az6 and I'm a lot nicer to it in the sense that I'm not trying to shift hard and fast I try to treat it nicely. I still hammer on my car often but I'm not trying to rip gears as fast as I can. I think the weakness of the az6 is when you try to drag race with it or shift incredibly fast under power.
