Purchase VAC - 4AG 1.8L Stroker Kit "8AG"

VAC - 4AG 1.8L Stroker Kit "8AG" After the success of many of our stoker engines in international competition and street performance in our various BMW applications, the goal of creating the ultimate 4AG Stroker Kit (aka "5AG" or even "8AG") was naturally well within our reach.

Over the past two years, development of this kit was honed and the use of only the best products available, to ensure reliability, were specified.
No products of questionable sources would make there way into this kit. This includes products that state "made in Japan" but are actually made in China and simply quality-controlled in Japan.
Everything in this kit is designed for competition use at high RPMs and to be of true race grade quality out of the box; no excuses... And, after all of this, many of our customers who buy this kit... are in Japan!

Club Sport Kit: An affordable option yet still made for the rigors of professional racing. Our private label SP Components Rods & VAC crankshaft offer unrivaled performance, yet our flexible manufacturing techniques allow us to pass fantastic savings on to you. CP Pistons offer your choice of compression.
Competition Kit: All components of this kit are made in the USA of the finest raw materials and by the finest manufactures in their respected areas of production, with the option of Arrow Precision rods made in England. This is the ultimate high end kit in the world. CP Pistons offer your choice of compression.

Several different configurations are available to give consistent, reliable results. Shorter length rods are not used in this kit that could negatively affect piston-to-rod ratio.
With proper ECU or carb tuning, you will leave the competition in the dust!

    Our Stroker kits are supplied with:
  • 4AG Stroker Crankshaft, 83mm
  • (4) CP Pistons; Custom specs with high quality Rings, Pins, & Locks (in CR & Bore of your choice)
  • (4) Con Rods; forged in 4340
    *Please note image is for example only*

      Features:

    • Perfectly suitable for the street or for full race use.
    • Match to our variety of high quality rods
    • Excellent Piston to rod ratio
    • Large valve reliefs for aggressive cams
    • Various CR & bores available for 16v & 20v applications.

Build yourself the ultimate 4AG! Please call or Email one of our techs if you have any questions or require a custom kit.

Notes:
Professional install is a must with this kit, block clearances must be made. We highly recommend the use of upgraded ARP hardware (also available) and upgraded crank caps with this kit.
