Stock 5efe turbo conversion help?

2720 Views 2 Replies 2 Participants Last post by  Boosted_5EFE
I have a '96 Tercel L50 coupe with a stock 5efe, and I dont know much about these engines, and I was wondering what some good ways to go about turbo charging it. Like what I should use to tune it for the turbo or any top end or bottom end changes that would work, and where to find them. Thank you

The '96, from my understanding, has the more desirable connecting rods (more robust then the '99).

I have boosted my '99 Tercel manual with a stock 2nd gen 5EFE. Boost is currently set to 8 psi.
Recently dyno tuned (graph shown below) and daily driven as a boosted car for almost 2 years now.
All work was done by myself.

This is what I am currently running.
  • Stock internals on a well serviced engine (recommended rod upgrade but I am running the stock thin ones currently)
  • TD04 (JM Turbo or from a Subraru)
  • TD04 mount exhaust manfold (ebay)
  • AEM FIC6 (shop around for best pricing)
  • FMIC (ebay)
  • Bosche PN: 020150, 315 cc injectors (from a Volvo or Rock Auto)
  • TurboSmart IWG, 5 psi spring (shop around for best pricing)
  • MBC (Grimmspeed)
  • 255 LPH fuel pump (Walbro)
  • Converted to return fuel system (misc stuff from Summit Racing)
  • FPR set to 48 psi (Turbosmart)
  • Boost/Oil pressure/AFR gauges (GlowShift / AEM)
  • Wideband O2 (AEM)
  • Smaller dual core rad (from Civic or ebay)
  • Stage 2 6 puck clutch (Rock auto )
  • 195/50R15 tires on 15x7" wheels (inexpensive Sailun Artezzo SH402 and Konig Dia-lin)
