This RB30 build for GC Restoration customer car, LIL H, has been an absolute pleasure from start to finish.
The car came in for a freshen-up and full rebuild, and we didn’t hold back. It’s now running Spool Imports H-beam rods, Ross Pistons, ACL Race bearings, ARP studs, an N1 oil pump upgraded with HSE billet gears and a crank collar, plus an aeroflowperformance high-volume sump to keep everything fed properly.
The head was already ported with cam and springs, but we stepped it up further with +1mm oversized valves, all genuine seals, and a nittoperformanceengineering head gasket to tie it all together.
On the intake side, it’s running a CPC carbon plenum paired with a boschaustralia 82mm DBW throttle body, while the exhaust setup features a 6boost manifold and a G35-1050 turbo, supported by Zoo Performance oil and water lines.
Built right, dialled in, and ready to perform.
With the help of Scott Hoffman from Cleveland Dyno, it now makes a comfortable 581hp at 23psi on 98.
