5efhe mod....

this is something i read in the toyotaowners.com forum

You can also use the 5EFHE with the 4EFTE harness and ECU, the CT9 turbo and manifold from the 4EFTE, with a set of 370CC injectors from a N/A Supra with a AFC for fine tuning. Using a base timing of 5 degrees this combination is very reliable as a daily driver and a blast to drive. This is the combination I am currently running in my Tercel. The other option is to have an exhaust manifold made, use either a Mitsubishi 16G or 20G turbo with either an SDS or Megasquirt stand alone computer system and you can make 190 to 210 at the wheels on 93 Octane using the 440CC injectors from a MR2 driven daily using 15 to 16 PSI of boost. Since not all 93 Octane fuels are the same additional safety may be provided by adding a bottle of 104+ Octane booster. Please note the engine is still internally stock.

well, i think a 4e harness alone is hard enough to find. and manifolds are expensive. and 5efhe's are rare enough too i think?? could be wrong, but for this much trouble, you might as well swap in a 3S

I'm doing pretty much that with my 5efhe.

But I wouldn't suggest using the 4efte manifold, it's too restrictive for the larger 1.5 liter motor. Easiest thing to do it modify either a 5efe or 5efhe manifold to accept the turbo.

The CT9 is also a little small and I think it starts to run out of breath once to start really revving it up high. Best to go with a TD04L or T28.

Tuning on turbo 5efhe is very important, so get a professional to do it. I got the Greddy E-Manage Blue to take care of my engine management.

Doing this is super easy compared to a 3S swap.
