Got my personal Barra setup all bolted together and ready to finally make some power

Quick rundown on the engine combo. decked block honed out to 40 thou, hypertec 40 thou pistons with clips and gudgeon pin upgrades on-top of a fg turbo rod , Acl race main bearings and conrod bearings, mls head gasket with head studs to hold everything together, plazmaman HD valave springs, billet oil pump assembly, factory cams and vct.

For the bolt ons I’m running a t04z turbo 1.05 rear housing should spool up instantly paired with a 44mm wastegate to keep the boost steady, all that is sitting on a custom GR promod manifold utilising 40nb runners and staying equal length. This thing should sing and make power throughout the rpm range.

Keen to get the setup into the vc and start finishing off all the fab work and get it on the track to see what It can put down 👌

Here’s Jacks GR spec Barra setup going into his XD falcon, was a factory NA bf mk2 motor. Came in getting a full refresh upgrading the stock 1r23 rod and pistons to a 1200hp s**t h beam rod with polished Xr6t piston, the motor has be gone through top to bottom getting all new bearings, custom GR spec ring gaps, billet oil pump assembly and heavy duty valabe springs with head studs and a mls gasket. This setup will be in the 800hp range easy on e85 👌

Coming along nicely

Some progress on the Barra manifold going into the VC commodore. full equal length runners with 40nb steam pipe throughout.should be plenty to spool the T04z.

Good start to the year having multiple builds coming in and out of the shed.
This is konar’s BA xr6 turbo that came in a week ago to have a full ground up rebuild to suit 500+hp
Big set of cams, valve springs, upgraded to 3r23 rods and new custom file ring gaps to suit. Should be plenty for his daily.
