GTX2867R on the way! Big thanks to @[email protected]!

Already have the GT2871R of course. Turbine side is identical, so keeping my existing big turbine housing and just swapping CHRA and comp housing. Selling the 2871 guts to local guy, so it works out pretty well. Shooting for a solid 400whp now, no meth/water. This compressor will give me a lot more headroom, ability to run more boost, and more efficient everywhere.

Waiting on a call to go pick up the IM flange. Then off to another race shop fab to get the Intake cut and the flange one.

The flange is being water jet cut.

Also waiting from another shop to go pick up the custom made torque plate, so I can bore and hone the block.

so looks like the turbine is the same, just the new compressor wheel design...been a long time since they've improved the wheel...---- has been the same since the 80s.

yep spot on. Doesnt seem to be a lot of info/dynos with them on the web...literally only 1 video of a dyno with one on youtube, last time I checked. But just going by the compressor map, looks pretty sweet, even up at ~25psi it appears it would still be very happy. My plan is to boost about 20 initially (after break in, etc.) and see what that gets me/how it feels, and go from there. I have a feeling that will be scary enough.

Searching around, looks like another good option for 28XX users might be this HTA upgrade I came across

TU2868RHTA Upgrade customer's GT2860R or RS to a 68mm HTA billet compressor wheel $700.00

Build coming along slowly but surely. Currently Bogus is waiting on drill bits to get the torque plate finished up before boring and honing.

Ordered Supertech valvesprings, titanium retainers, +1mm intake and exhaust valves...

I jumped in on a Web Camshaft group buy, going to be getting a custom set from them. Talked with them today briefly... haven't decided on an exact grind yet, but basically going to emulate a Evo/DSM 4G63 "272" cam.

Gotta get these damn Toda cam gears now too, ugh.

Did he ever post up specs? I recall seeing a thread, but never specs posted. 272 duration (222 ish @ .050") with 11mm of lift should be pretty darn good.

He has it listed somewhere.

Do what he did so you can do this.
