We are very luck to have special relationship with Ross Pistons to have 1-3UZFE pistons made.  The pistons are forged with strong pins along with performance rings.  There has been a myth that Lexus put in forged pistons in their 1UZFE.  I have a 1990 LS400 and the pistons were not forged.  The stock pistons can handle some punishment, but will give up after 12-13 psi.  We had Ross to custom made us a set of forged pistons with forced induction in mind. 

The weakness link in our Lexus-Toyota Motor are the pistons.  I have seen lots of Lexus-Toyota V8 motor blown because of its pistons.  Here is your chance to do it right at the first time.  We are offering custom made pistons for any compression ratio or oversize bore along with either Natural Aspirated (N/A) or Forced Induction (FI).

We have many years of experience ordering proper pistons.  From the early 1uzfe models to the latest VVTi 3uzfe.  Just tell us the followings:
 · Compression ratio
 · Over Bore Size
 · Horse Power Level


  • Ross will make our pistons from 2618T61 forged aluminum.


  • Ross will be using special custom rings for high boost application.
  • Currently Ross has the following, but they will make us special rings stronger when they have now.


  • Ross 4340 pins are the ultimate pins for strength.
  • They are made from billet bar stock 4340 chrome moly, which has a minimum tensile strength of 240,000 psi. and a 13% greater ductility than standard pins.
  • The hard chrome finish provides excellent life.
  • 4340 pins are recommended for sprint cars, blown engines, etc.

The one set price for those pistons at regular price is $1100.00 (Pistons, Rings and Pins) plus shipping.  However, Ross can offer us $850 shipped.  Yes, FREE shipping anywhere globally at $40 value.  Please contact me if you are interested and allow 5-6 weeks for delivery.

Here are my recommendations:
·  N/A Application: .020″ overbore and stock compression ratio
·  Supercharger: .015″ overbore with stock compression
·  Turbo (Mild): .015″ overbore with 9.5:1 compression ratio
·  Turbo (Wild): .010″ overbore with 8.5:1 compression ratio

Please file out compression ratio and overbore when you pay.  Secondly, ONE quantity is 8 pistons, 8 pins and 8 set of rings.  You can purchase more than one set of pistons.

This is a freelance site with no support by huge companies.  I have been doing most of the R&D and technical write-ups by myself with my personal money and literally thousands of hours of my time.  I have taken extra steps to demonstrate in details how things are done.  Currently I am one of the few people doing Lexus V8 research and performance enhancement.  This effort comes from my personal love for this wonderful engine.  Most of the modifications are from trial and error. There's no cookbook for 1UZFE mods and its unknown territory for much of supercharger performance.  The parts, labor, web development and site hosting are 100% paid from my personal hobby money.  If you feel my efforts help you in any form, please do not hesitate to donate any amount of money to support this site. You have no idea how much I and the entire Lexus and Toyota community appreciate it!
