HKS GT-R R35 Capacity Upgrade 4.3L Kit
Available for these Applications:
2009+ R35 GT-R VR38DETT
In order to further power up 4.1 L KIT for VR 38 DETT, it was renewed as 4.3 L KIT.
By reviewing the shape of piston and newly setting special oil jet for optimum cooling, more precise balancing of crankshaft, etc.
· Adapted to higher torque (allowable torque: 150 kgf-m)
· Genuine Low level vibration equivalent to level
· Realized the world's highest level long stroke (stroke: 99.0 mm)
It became a kit that corresponds widely from street to circuit.
- By fully cutting out from a forged round bar, we realized the ideal shape without ova.
- It adopted exclusive truss shape, realizing high strength and super light weight.
- Secure squish area and realize high speed combustion.
A full cutting piston ensuring a squish area and realizing better combustion
Crankshaft with 99mm Stroke
- Without changing the bore size, a wonderful 99.0 mm stroke is realized.
- Adopt full cutting out crank from round bar.
- Precise balance adjustment was carried out against the vibration unique to V6. I keep it to a level where there is no problem in town riding. (Can not be combined with kit external products)
- In preparation for an increase in the burden on the main metal due to ultra-high torque, we adopted a structure that improves hitting of metal and reduces the load.
- By adopting heavy metal and adopting highly efficient balance weight, lightweight and high response is realized.
- Along with the long stroke, a dedicated connecting rod is set. Processing on the engine side has been kept to a minimum.
Corresponding to normal bores 95.5 mm
- Adopting genuine bore size which is ideal from the viewpoint of heat conduction so as not to drop the block strength which is a part of the performance of the engine itself.
- In terms of cost, you can reduce the cost of parts, liner processing costs, block top polishing etc that are required for liner processing.
Exclusive Oil Jet
- Dedicated oil jet for optimum cooling of dedicated piston for kit was newly set up.
