MWR Customer: Shannon Sims

Monkeywrench Racing Features: Shannon Sims, of Midland Texas

Shannon has another great 7th gen Celica, but this time, it’s a GT!

These shots are from his local area in Texas.
Onde again, Shannon tells the story better than we can, so you can read it in his words:
I purchased this car from a used car dealership in an adjacent town.  I remember saying out loud “I’m not going to do anything to it”.  I slowly but surely abandoned that statement!  I started out with the basic traditional mods: CAI, Header, ZEX wet nitrous kit, and exhaust. This just didn’t do it for me.  So forced induction was the only option next in line for me.  I started out with, lets just say a very unpopular turbo kit that caused a lot of frustrating nights in the garage.  I later found out about Monkey wrench racing. I gave them a call and they literally help me get my Celica up and running.  Matt and Gary from Monkey Wrench Racing have been a creative and resourceful extension.  The pictures are of my old set up which was:
  • Garrett DBB Gt2871
  • Stock Automatic Tranny
  • Crower Rods
  • Wisco 8:8:1 pistons
  • MWR FPR kit
  • MWR 255lph fuel pump
  • MWR 630cc Injectors
  • AEM Wide-band Air fuel Ratio Gage
  • GreddyEmanage Blue
  • Nitrous inter-cooler ring
  • Apexi digital boost controller
New set up is currently in the building stages: here is a list of the new mods
  • 6speed Celica GTS tranny swap
  • MWR Chromoly Ultralight Flywheel
  • RPS Max Street Clutch
  • MWR bushings
  • Fidanza short throw
  • Crower stage 2 turbo cams
  • Crower springs and retainer set
  • MWR Valves set
  • Three angle valve job
  • Garrett DBB GT30R Turbo
  • TiAl 50mm BOV
  • Wide-body Kit
  • Greddy Emanage Ultimate
  • Custom inter-cooling piping set up and Apexi muffler
The car started out with a automatic tranny and its been ripped out and replaced with a GTS 6 speed tranny.  The car is just about complete, once it is I will send dyno videos and new pics.  Thanks to the guys at Monkey Wrench for there hard work and dedication to the 1zz and 2zz platform.  I have known these guys for about 3 years now and they have been a great help!

If you would like to have your car considered for the Monkeywrench customer of the month, please send an email to and include as much as possible about your build including pictures, dyno sheets and timeslips when possible.
