#E7#-Corolla technical info (KE70, CE70, TE70, TE71, TE72, TE73, TE74, TE75) NEW! Corolla #E7#, 1979-1987 History
This is a TE71 Trueno Apex with 2T-G -engine for japanese domestic markets. The picture is taken from Kishino Makoto's webpages with permission. The original first generation Corolla (KE10) was introduced in November 1966. The #E7#-serie is the fourth of the generations. In between these models is the second generation corolla; #E2#-series Corolla (KE20 for example) That series was introduced in 1970.5. This #E2#-Corolla was also very popular for performance mods, mostly because of it's low price and lightness, maybe because of looks too (?). Next generation Corolla was logically #E3#-serie (1974.4-), but it has models from KE30 to KE65, for example and therefore next serie didn't have the most logical name #E4# but it was the #E7#-serie. Fourth generation of Corollas, #E7#-serie was introduced 1979.4 and it lived (in sedan form) to the 1983.5 until the #E8#-series replaced it. All cars of the serie #E8# were now front-wheel -drive (sucks!) models, exept the AE86 and the #E7#-station wagon since it's production was continued to 1987. Even though KE70 (850 kg)seems to be larger than KE30 (870 kg), it is lighter than it. Only bigger improvements were made for the model year 1982 (in european/skandinavian/Finnish export-models); Corolla had the big lamps, black bumpers, the "waist-line" was lower due of bigger windows, 1300cc engine was improved with higher CR (compression ratio), changing the shape of combustion chambers and 5 hp. It was possible to choose 2 or 4-door sedan, 3-door Coupe or the 3- or 5-door station wagon. Original engine alternatives were 1300cc 4K, 1600cc 2T, 1800cc 1C, 1800cc 3T and 1600 8-valve twincam; the 2T-G.
This is my KE70 with the 4A-GE and Ae86's axles (coil-overs front). Corolla #E7#, 1979-1987 Modifications Corolla #E7#-series cars are popular in Finland (at least) for engine-swaps, and for a first car to a person who likes to have a RWD (rear wheel drive) car with the small amount of money. I am poor too, and that is the reason why i have a KE70 too :). #E7#-series Corolla is also popular in the crowd of teenagers, who has just earned their drives licence, but usually their mods are something that i don't understand. They deal with fuzzy-dices, 225-45-16 tires with standard suspension and 3" exhaust pipe (without it 1300-powerplant couldn't breathe well). Anyway, i will try focus on to principles of the handling and power improments of a #E7# without blaming those simple fuzzydice-Corolla owners. If you want to be rational, build the suspension first and the powertrain then. Engine is the last target to modify. Many of the Corolla GT Coupe/Levin/Trueno's (AE86) parts are interchangeable with the older #E7#-series Corolla due of the almost similar floorpans. Since Corolla AE86 is very popular car in the world, there is many donor cars and spareparts around. Even in Finland (car-tax paradise) is rather easy to find parts of an AE86, though parts availibility is mostly merit of the rally-drivers here. AE86 has been quite sovereign in our own Gr.F (or in a F-cup, to be exact). AE86's suspension is the way to go when you are improving the suspension of the #E7#-Corolla. That is the first step to a "poor man's Levin". Better axles of an AE86 with bigger brakes fits easily to #E7#-Corolla (except to the station wagon-model, which has rear-axle with leaf springs). Front axle from the AE86 has big ventilated brakes, for example. Also there is disc brakes, LSD (limited slip differential) and (a tiny) swaybar in a rear axle of the AE86. With just these modifications will make your Corolla handle better. Better is anyway enough, since even AE86 is quite scary car to drive for a first-timer. When a (standard) AE86 was in rapid a slalom-test of a finnish magazine called Tuulilasi, every journalist/Test-driver who drove the car spinned with it. In the other hand, with the right modifications Corolla AE86 (or #E7# with the same axles and suspension geometry) will handle almost like a go-cart. Though AE86's nature will always be oversteering, which is funny and positive thing for a drivers car :). If you are changing the suspension from an AE86, or from whatsoever car to your dear #E7#, you must upgrade your suspensions bushings (Yes, these black, craked ex-rubber ones) to better, stiffer ones. If you don't want to build the suspension what is comparable to a russian tank, you don't want to install metal- (uniball- or heim-) joints. I suggest you to choose polyurethane bushings or the whole suspension bushing set from TRD (Toyota Racing Development). I choosed my bushings from the selections of Energy suspensions, because Powerflex's bushings are almost as soft as standard rubber ones. Powerflex bushing are more endurable than standard rubber bushins, though. There is also polyurethane bushings that are made by an Australian Fulcrum suspensions, but i don't have any personal experiences of that brand.
Uniball-rodend is used in pure racing cars/hardcore street driving-cars. If you can choose what model of #E7#-Corolla you are going to tinker, choose KE70, with 2-doors and 1300-engine (4K). This model has the rack&pinion-steering when 1600-model has numbier and heavier recirculating ball-steering. Rack- and pinion-steering leaves more space to your cars engine compartment as an additional bonus (for the later installation of turbocharger, for example :) ). Body of the two door-model is lot more stiffer than four-doored "taxi-model" has. Stiffer body is good in the sake of handling. It is suspensions function to flex, not the bodys job. Body of the 3-door coupe is the softest body of the #E7#-series. Surprisingly the AE86 (with 2- or 3-doors) has the yet softer body than any of the older #E7#-Corollas. Sunroof (which is not popular in the Finland for two reasons..) is not good, if you want a stiff body. Have you ever seen a racing car with the sunroof? Gearbox and clutch should be upgraded too. If you for example are going to replace your standard engine with 4A-GE, you should choose the clutch and transmission from 4A-GE. The
engine is the heart of the heart. I have seen many different engines
in #E7#-series 'Rolla. Usually it is (among the standard mills) 2T-G,
18R-G (shown in the picture) or 4A-GE.
There is a list
of parts needed to swap T-series engine to the A-series engine.
The picture is taken from Twinchargers
excellent websites.
The famous 2T-G from Jankens website sitting in the engine bay of the TE27 Wiring is the job that i don't personally like much (maybe because i am not good at electronics..), but you should naturally get in the first place the wiring diagrams of your car+the engine you are swapping in. There is 2T-GEU and 3T-GTE's diagrams. If you need some other diagrams, go to the (in case of 4A-G# -engines) club4ag or to Matti's (Kalalahti) and Helen's webpages. There should be the ECU's connections for many popular engine-type at least .

Those
crazy Australians have been using even 1G-GE or 3S-GE! However, there
is many engines that could be made to fit easily in the engine room
of the #E7#-Corolla. Just for example,
