Engine: 1993 3E-E 12 valve, 9.4:1 compression, 1.5L (all stock internals). W/Turbo @ 10 PSI.
This car, I bought for $200. I found a $25.00 junkyard turbocharger from a 1988 Mazda 323 GLX Turbo 2.0L. The little IHI turbo is the same as a RHB5 (it is called a VJ11). Anyway the turbo works great on the 1.5L engine. I am using cast pistons, which they say can't be done. I've ran it for 3 months full throttle everywhere, up to 13 psi boost, no problems yet. I run it at 10 psi boost and the car is very powerful. I would estimate about 140hp, though I could be wrong.
295cc Supra injectors don't work, they idle too rich with my stand alone fuel management, and they cannot be turned down. They are too big! I am switching to 213cc Toyota MR2 (4AGE 1.6L) fuel injectors and that should do the trick.
This car has a bone stock engine. Except I made the stand alone fuel management from scratch. I soldered it together as a kit. It is called "megasquirt" if you haven't heard of it. Megasquirt controls fuel and spark, and it only cost $187, but it is a bitch to understand and build. I managed to use the stock ignition system, except I had to remove the Toyota ignitor and put a Saab Turbo spark module on the firewall, since it is a digital spark module, like an MSD, and it is easy to figure out, and doesn't require any special settings. It controls the stock Toyota coil, with the stock Toyota distributor and it works great! Yes, I am using a Volkswagen spark module on a Toyota... I know it is pretty funny!
This car flat out rips. Don't bother with a 1.3L swap, or a 4AGE... I've pushed this thing as hard as possible and haven't even blown a head gasket. At 10 psi boost with good spark timing and good fuel, the thing flat out screams. The stock camshaft in the 3e-e means the engine runs out of steam up top, but the rush of acceleration to 5500rpm is so strong you'll never get tired of it... It feels like a muscle car.
All the other special fittings are custom made via silver brazing (not welding, not soldering).
I brazed the side of the oil pan with a fitting so the oil drain from the turbo could go into it. The engine starts and idles and sounds like a stock Tercel... It drives like a stock tercel, though the turbo begins kicking in without any turbo lag at all, so the more you push the throttle, the more the car starts feeling like a V8... It doesn't feel like a V6... It feels like a V8... The torque is unreal as anyone with a boosted car will know. Boost rocks... Even on a 1.5L 12 valve engine, ha ha!
I had to build my own fuel rail because I used a 1990 California Tercel low compression cylinder head. I could not find the accompanying factory fuel rail. I had no other choice but to build my own fuel rail. I used mild square steel for this because it is easy to work with and cheap. For the fuel injector bungs, I found an old Nissan fuel rail made out of steel, and I cut off the bungs. I silver brazed the bungs onto the mild square steel with the proper alignment. For the end threads, I used a motorcycle wheel nut hand filed to the proper fit. This took considerable time. The fuel rail sits like the stock rail and uses the stock fuel feed line, and the original banjo fitting (see pic). I've been running this fuel rail for about a month now.
The picture below is the Megasquirt Version 3.0 with Megasquirt N Spark software.
You program it with windows XP and you can tune the car as you drive. This is the only stand alone management I have ever worked with and it was a breeze to setup and get the car running. I made an adapter so all I had to do was unplug the stock computer in the Tercel and plug in my new Megasquirt computer. I used all the stock existing sensors and wires. I didn't have to change any of the wires under the engine compartment, I litearlly just plugged in my new computer. Making that adapter harness took many hours to get right... The manuals are hard to decipher. I did manage to get a couple wires wrong. I still don't have a fast idle valve hooked up, so the car starts hard in the cold, and I don't have a fuel pump turn on, since I wired that backwards and burned up part of my computer that kicks the fuel pump on. I can fix it pretty easily but haven't yet so I installed a toggle switch for the fuel pump.
