Top 10 things that make the R18 perfect for boost
ultra-lightweight engine, and transmission, showing cyl head with integrated manifold
Bore and Stroke are identical to the legendary GSR and ITR B18
The R18 uses a full 1-piece main bearing girdle
"Long-rod" Forged Steel Connecting rods with rod BOLTS (not studs - easy to upgrade to ARP hardware)
The R18 has a 10% reduction in friction from a special cylinder wall hone and moly-sulfide bead blast and ion treated piston rings. High durability and low friction.
pistons cooled by built-in oil jets (typically only found on high end honda motors). This is important for a turbocharged engine which has increased piston temperatures.
cylinder head design is an ultra efficient way to deliver high temp exh gasses immediately to a turbocharger
Easy to disable EGR using OE Honda components
the R20 is available for more power and any R18 guys looking for BIG power can do a bottom end swap to the R20 (or sleeve your R18 to 2.0L!)
Hondata FlashPRO is available!! MAF based engine management makes tuning very accurate and simple
