Nissan SR20DET 91mm Billet 4340 Stroker Crankshaft - Rated at 1000hp and 10,000rpm

This is a true billet crankshaft machined from Billet 4340 core stock (not a cast forging blank that is final machined).

Each crank is machined from core stock 4340 on a CNC machine, then Nitrided and final ground.

Rated at 1000HP plus

With the increased cubic capacity from the 91mmstroker crank, big increases in torque and low to mid range power are achievable. Boost will come on earlier in the rev range and peak power will increase.

The SR20DET engine in its factory form has a 86mm bore and 86mm stroke, giving a displacement of 1998cc.

Using the 91 mm stroker crank, std length Conrods and Custom Pistons, the displacement is increased as follows:

  • 86.5mm bore and the 91 mm stroker crank = 2139cc / 110cc increase
  • 87 mm bore and the 91 mm stroker crank = 2164cc / 133cc increase
  • 90mm bore ( sleeved ) = 2316cc / 318cc increase
  • Crank Weighs 18kg
  • 4340 Grade Billet Steel
  • Fully Counter Weighted
  • Nitrided Finish
  • Fully Balanced
  • Stroke 91mm

Delivery & Freight

We are an Australian-based company that ships items nationally and internationally, usually within 48 hours of receiving your order. High-value items shipped internationally are sent via DHL Express, while lower-value items are sent via Australia Post Express unless otherwise instructed.

You can calculate shipping rates inside the shopping cart. After adding all the products you would like, navigate to the cart and click the ESTIMATE SHIPPING & TAX link. For Australia, you need to select from ALL dropdowns (Country, State, Suburb, and Postcode) for the quote system to work. (There may be a small delay as it searches.) For international orders, you only need to select the Country to get a quote, but more details are required at checkout to complete the order.

If you have issues calculating freight, please get in touch. The most common reason for issues is that the postcode does not match the suburb, or the suburb is spelled differently from what the carriers have.
