The availability of parts for the Paseo and Tercel has sorely lagged compared to other Toyota models (and worse- compared to other brands).� Being part of the Toyota family- the Tercel and Paseo are wonderful cars, that many owners feel should be rewarded with upgrades.
The 89 Tercel we converted was the fifth vehicle of a computer consultant, an extra car that has served it�s purpose but was too good to get rid off.� The goal was to maintain the stock look but upgrade the chassis to a higher performance level- just like upgrading computers, there are many changes you can do- but it all has to work together.
The tired engine was replaced with a 4EFTE- basically a turbocharged / twincam 16 valve version of the original 3E engine.� Being of the same E engine series- the conversion was a drop-in deal.� The conversion is straightforward- but you need all the parts.� We actually started with just the basic engine, but had to import a lot of other parts.� We used the factory 4EFTE EFI system.� If we had started with a 4EFTE conversion package- complete engine, wiring harness, and ECU- it would have been a lot easier.� (There are some other relays and sensors that will be needed depending on the car the engine is being installed in.)��
Since this car was not an original EFI model the fuel delivery system had to be up-dated to a 90 and up model.� The Tercel is a much simpler car than others and rewiring to accommodate the new engine and was also much simpler.� The harness has to be modified to configure to left-hand drive.
The 4EFTE comes with a top mounted intercooler, but we opted for a more efficient front mount unit.� We used an air to air HKS unit, that was originally made for the 22RTE pick-up.� This also allowed us to maintain the stock look, instead of having to add a hood scoop. We retained the original automatic transmission and added a modified torque-converter- since turbos always work a little bit better with auto-shift.� The axles were rebuilt at the same time.
The front brakes were updated to cross-drilled units and Repco pads / shoes all the way around.� The suspension was upgraded with Tokico HPs with the stock springs, in keeping with the desired ultimate �sleeper� look.
Recaro N seats were the only other upgrade- when you think about it the seats are the only part of the car that actually touches your body.� The car had an immediate different feel.
The installed engine is basically a stock as installed, but we have ready a built 5E block (with forged pistons) and a bigger turbo.� With some slight ECU mods, this engine will produce 200HP!!!!
