R32 GTR CP Pistons 86.5mm 9:0:1 N1 Oil Pump w/ SPOOL Spline Driven Billet Gears Manley H-Beam Rod w/ 2/8" ARP 2000 ACL Main Bearings ARP Head/Main Studs SuperTech 70lbs Single Valve Spring w/ Titanium Retainers ECU Masters EMU Black HKS 2530s rebuilt with billet wheels Radium Fuel Rail ID 1050 Injectors (Resistor Box Deleted) Aeromotive FPR Frenchy's (FPG) Fuel Pump Assembly w/ Baffles Walbro 455 Uni-Group 260/260 10.9mm lift Tomei Adjustable Cam Gears 512 WHP at 15 PSI 357 ft lb TQ(E85) 569 WHP at 20 PSI 396 ft lb TQ(E85)

I originally was shooting for 450 to the wheels and met that goal and some thanks to E85 😈. Low boost 15 PSI 513WHP and 357 TQ. Due to stock tranny high boost is stopping at 20Psi and 569WHP 396 ft lb TQ. I’m very happy with these numbers and cannot wait to learn this new beast.

Long overdue but the journey has come to a beautiful moment. Motor back in and back on the dyno IMG_6867.MOV IMG_6870.MOV IMG_6869.MOV

A little more progression photos: had to order 28 shims from SuperTech to get to this point. But finally both intake and exhaust completely done. Waiting on the head gasket now. (It’s enroute). It’s a tight fit!

Just more eye candy for the meantime...

The head came back and now it’s time to set up the valve train

Not sure if I’ll be able to get the head Into the shop before Christmas but the cams are fitted and ready for the rest of the beadwork!

Block didn’t take long to get built and shipped. It landed this past Friday at the shop. It was a smooth and easy business transaction with the shop in Canada. Also the Unigroup camshafts came in. Got them fitted up and ready to send the head off to get cleaned and the New valves (guides and seals) installed. More to come.... IMG_3442.mov

Make a bushing the size of the head stud hole with clearance for the stud in the hole, than install with sealant, stops any possible transfer of coolant. Bushed holes should have sealant on the head stud instead of arp lube

Bushed, Decked, and Honed. Ready for pistons....

So I’ve contacted Unigroup Engineers about their cams and I liked what I was told. So I’ll be going with the 260 IN/EX with 10.9mm lift. The CP Pistons states: “CP pistons are compatible with oversized valves and higher lift cams” Due to this change I’m going to switch to a dual spring set up from SuperTech (SPRK-M1007D/RB) - 92lbs @ 40.70mm In / 82lbs @40.70mm Ex —232lbs @ 11.00mm In / 222lbs @ 11.00mm Ex Max Lift: 15.3. About to start ordering the parts to get this in my garage by Christmas!

I want results. Who's gonna see "Tomei" or "Kelford"? Brands aren't priority on camshafts for me... Exhaust system different story lol

So I have got the ball rolling on the next step for this build.... I slept on it for a few days and decided that the best option for this would be to start it all from scratch. After sourcing different options and not wanting to "trust" someone's word on the mileage, who built it, what parts were used, etc... I decided to go through a reputable shop in Canada. Saint John Engine Rebuilders. They have done tons of motors and supplies a decent amount of RB builds to the USA. Bottom End As Follows: Rb26 Block w/ bushed decks (for the common head bolt hole crack) New Crank CP Pistons 86.5 9.0:1 Manley H-Beams N1 Oil Pump w/ Spline Drive ACL Main Bearings ARP2000 Main Studs. As far as the head goes. I am still looking at higher lift cams for more torque while keeping the duration in a nice range for the 2530s. (open to input). But the list of what I plan to do now: Metal Headgasket 1.1-1.3mm Tomei metal Gasket set Supertech/Brian Crower Single spring & TI retainers Supertech Valve guides intake/exhaust Supertech valve seal exhaust/intake Intake/Exhaust valves +1mm
