HKS Complete Engine RB26 2.8L STEP2 V2
[Complete engine RB26DETT 2.8L STEP2 Version 2]
Version 2 has improved intake / exhaust balance by adopting a big valve for exhaust, optimized the port shape, and cut the valve seat into an R shape to prevent the boundary layer from peeling off. Released.
- Proven 2.8L STEP2 kit assembled by skilled workers on N1 block
- Improves intake and exhaust efficiency by optimizing the exhaust side big valve and port shape, and measures against heat with sodium-filled type
- Combustion chamber shape optimized by NC processing to suppress knocking
- Super cooling head gasket and head air vent hole processing to improve head cooling
- Adopts a proven large-capacity reinforced oil pump to ensure stable oil pressure in the entire rotation range
- The main bearing and connecting rod bearing are subjected to numerous tests to select the optimum one.
- Measures against pulling out with grommet head gasket and reinforced head bolt
- Assemble a high opening camshaft to ensure high rotation elongation
- Uses reinforced valve springs and titanium retainers to prevent surging at high revs
- A reinforced valve stem seal is used to ensure valve sealing at high speeds and high temperatures.
- Uses a separator that shuts out the oil that flows out from the cam cover together with blow-by gas.
* It is recommended to use HKS Racing Pro 10 W50 as the engine oil.
