Honda K20A2/Z3 9.1:1 (Turbo) Build For Sale

Hey Honda-powered People,

At long last I’m selling my k20a2 block+k20z3 head long block, built by Rich Olivier of TEM Performance Machine Shop in 2017. TEM specializes in race builds. Solid rep. Check them out.

Build overview:

    • 9.1:1 ceramic coated pistons
    • Supertech dished race valves and springs (jhpusa.com “super combo”)
    • Supertech block guard
    • Ceramic coated CP pistons
    • Pauter rods – I beam design reduces windage. More common to Porsche race builds.
    • APR head studs
    • Cometic head gasket
    • Toda Heavy Duty Timing Chain
    • Circuit Hero Timing Chain Guide
    • Skunk2 Billet Timing Chain Cover
    • OEM oil pan with 4piston baffle (to install)
    • OEM crank, sleeves and cams
  • Out she came... Needs a new loving home.

I ran it with 12-14 pounds of boost for 340 whp with a tune by AJ (IG post on dyno new tab) Performance In-Frame Tuning (opens PIT website new tab). Rich once said the build “will take whatever you throw at it”. But of course we all know running I wanted to run safe with lower boost. But if you know these engines you know what they can do.

I put under 7k miles on this build. I drove SF North Bay Area, peninsula backroads and along the coast some weekends. And ran four track days in group 4 with NASA. Mild, non-competitive fun. Ran like a top. Crazy fun – especially in a car weighing about 2100 pounds.

$3,999. OBO. Half the cost of same as new build. 

I’ve looked at the usual market places and forums and I don’t think you’ll find a better turbo-ready build at this price point. If you do, show me.

Enjoy

 

Honda K20 Elise Build Overview

Posted on by K20 Lotus Elise

Here is a list of essential components of this build (not comprehensive):

  • Honda k20z3 from 2006 Civic Si (used, 37k mi)
  • Innovative Mounts engine mounts, axles, shift linkage adapter
  • Garret GT30R turbocharger
  • DMC liquid to air intercooler
  • Hondata K-Pro ECU
  • Lotus wiring harness adapted by Rich Werks (Rich5150) with more adaptations by Enginetiks (Casey)
  • Injector Dynamics 1k cc fuel injectors
  • BOE Fuel Surge Tank
  • Innovative Mounts fuel rail
  • 2004 Honda RSX six speed transmission
  • Quaife LSD
  • Exedy stage 2 clutch and lightened flywheel
  • Hondata dash adapter
  • K-tuned coolant filler neck

Most all else is stock/OEM i.e internals, throttle body, etc.

Custom fabrication by Enginetiks:

  • Turbo exhaust manifold
  • Ported head
  • Exhaust with Borla muffler
  • Breather box
  • Extensive ECU wiring
  • Innumerable details of preparation, planning, removing (i.e. 2zz engine), acquiring, routing, adapting, mounting, fastening, welding, connecting… all done knowingly and deliberately, often fabricated using tools Casey fabricated.

Not listed here are numerous pipes/flanges/hoses/connectors/clamps/fasteners/adapters etc. etc.

Also not otherwise mentioned are the many hours of research and many miles driven by a number of people to get, modify, and deliver parts. To say nothing of the miles driven to and from the project, hotel stays, or ancillary and supporting efforts i.e. moving shop.

My grandfather liked to cite Edison’s axiom that “success is ten percent inspiration, ninety percent perspiration.” I would say my contribution to this project about ten percent, sub-divided in to stubbornness, curiosity, love of a dream, and vision, and of course some cash.

This Honda turbo Elise is not only inspired by Casey it is rolling homage to his skill and patience (especially with me). It wouldn’t be possible without him.

There are things to finish and repair to consider the project finished, yet. Not least is engine tuning. I hope it is finished someday Or do I?
