In Technical Information
The low compression type FA20 2.1L Capacity Upgrade Kit for high boost tuning.
Featuring newly developed high durable low compression pistons to take FA20
engine to the next level. Now available with Step2 billet I-beam conrods. The Step2 I-beam billet conrods was developed for the TRB-03 to deal with high output and high torque (approx. 700Nm) The buckling strength of the conrod is increased by approx. 30% when compared to conventional forged conrods.

The Engine compartment dress-up part; “Fine Tune V Belt.” Latest technology protects vehicles’ conditions while improving engine compartment appearance.
Using the latest in-belt technology gives the following benefits:
Increased durability at high temperatures which can be found in the engine bay of tuned vehicles.
Increased performance in cold weather and condition.
Lightweight and good friction tolerance properties which means that excess tension is not required while anti-sound properties reduces belt squeal.
Colored nylon fabric used for good anti-color fading properties.
EPDM (Ethylene Propylene Diene Monomer) Rubber was selected because of:
Better durability and performance in hotter or colder conditions with improved friction tolerance.
Much lighter than previous version of belt.
Short fiber mixture in rib rubber improves the performance over previous version.

The return of HKS Drag Specification Dampers! Introducing the latest technologies to suit modern drag racing requirements.
The MAX IV SP Drag suspension is based on the advanced HIPERMAX SP range and experience and know how gained from the ever-popular MAX II Drag Suspension.
Parts such 300mm long spring, helper spring, etc. are selected for each vehicle model to
maintain sufficient stroke amount and traction.
The shock-body length adjustable type is chosen to widen the vehicle height setting range and stroke distribution.
This drag suspension guarantees its performance in drag racing!
