AE112R Corolla Sportivo 7AFTE, Factory 7AFE Turbo Options

[hurley97]

I'm not sure if this has been posted before but I know a few people were looking for more info on the infamous factory 7AFTE and I haven't been able to find it here...


2001 AE112R Corolla Sportivo
only 100 produced
only came in gold
only sold in Australia
only made in 2000 for release in 2001


from a post on trdforums.com:

Launched in Australia in 2001, the Corolla Sportivo packs a turbocharged version of the base 1.8 litre twin-cam 4-cylinder. Curiously, the Corolla Turbo was released just months before the all-new Corolla series arrived in late 2001 – it was never going to be a long-running model.

Under the bonnet you’ll find a turbocharged 7A-FTE engine, which was a joint venture between Toyota and Tom’s. The 7A-FTE is an untouched garden-variety Corolla engine with a low-boost turbo system added. This means the standard 9.5:1 static compression ratio remains to help maintain excellent off-boost flexibility and all-round torque.

The turbo conversion comprises an IHI RHF4B turbocharger, a new cast iron exhaust manifold, revised exhaust, bigger injectors, remapped engine management, colder spark plugs and new inlet plumbing (which snakes its way through the engine bay from the standard Corolla airbox location). Boosting to 8 psi, induction-air is chilled by a front-mount air-to-air intercooler. The result is 115kW (156hp) at 5600 rpm and 237Nm (175 ft/lb) at 3600 rpm – but note that premium unleaded fuel is required to avoid detonation and extract maximum power.


more specs and info here













I wish I could find more detailed pictures of the engine bay. I'll keep looking though

nice find babe.

building an 8psi 156hp 7a would be easy, the part I find tricky is the EMS.

[celicaST]

woah never would of guessed. awesome find

[Silver94CelicaOw...]

Do it now, Stef. A low boost 7AFTE would be fun as hell, just a few tweaks of your new SAFC-II along with the injectors and fuel pump and you'll be ready for a reliable 8psi.

Looks really hot from up front. Not too sure about the rear though... :S

[94GT]

That is b@d@$$!!! Are there actually any part numbers for all of those components, or was it so limited that they don't even bother? It would be nice to have a clean looking setup like that in an ST...

I second this Question!

[hurley97]

thats exactly why I was looking for that car. I want to know what injectors, map sensor, and ECU are in it. I was hoping if I found the car I could look up the part numbers and then look up what other cars use the same parts...

[Batman722]

the map sensor is probably the 2 bar (same as the 3s) and they said they had tuning by Tom's so I would assume the ECU was reprogramed/flashed. That ECU would be BA to have IMO, it would make a turbo set up almost easy

[hurley97]

whats the part number for that 'turbo' sticker? I want one

[lagos]

it just goes to show that it can be done in a reliable way.

i think the big mistake that people make is that they set their HP goal too high and expect and safc to be able to tune that. that car is making a modest 156hp 175tq.... and thats at the flywheel!

or worse, they just slap things together and never even bother spend the time or money trying to tune it on a dyno.

neat looking engine bay. they really made that intake piping way out of the way. cant even see the turbo. neone wonder why they didnt do the 5sfte instead of the 7afte?
interesting out of all the turbo'd cars, i've never seen a company slap a FMIC on a stock model. but yet again they got together with TOMS.
neone notice that they only came out with a hundred of these? no wonder why most of us never heard of it.
crap - they got ventilated disk brakes on all 4. for not much hp they really wanted that stoping power

Whats the weight difference between a 7a and 5s?

Whats the weight difference between a 7a and 5s?

Doing the math through liters, the 5sfe is 18% heavier. I can't find the exact number on either one, but I did find that the 1999 Lexus RX 300 came with option of a 5sfe or a 1mzfe. So, there's another car to get parts from in the 5sfe to 1mzfe swap.

A: your math is wrong, 2.2/1.8=1.22 and B: that logic is completely flawed anyway

2.2-1.8=.4 .4/1.8 = .2222 = 22% So yeah, my math was a little off. I did it like 1.8/2.2=.8181 then 1 - .82 = .18 = 18%
So the 1.8lt 7afe would be 82% of the weight (if correlated to displacement/liters) of a 2.2lt 5sfe. And a 2.2lt 5sfe would be 22% heavier than a 1.8lt 7afe.

The logic isn't completely flawed. They have a very similar design with same materials such as iron blocks. You couldn't do the same thing with a 4age, or any other motor except maybe the 4afe. I'm not real familiar with its design, so I can't say for sure. I'm not saying it's exact by any means, but I bet it's not that far off.

LOL! So since when has space and mass meant the same thing? Nice try...

[hurley97]

...anyway.....

found one on cardomain. its a little modified though.

[Negative]

Do we really know if ht engine is truely the same as the ST Celicas? Might there be forged internals etc to aid in FI? What's the CR?

[hurley97]

thats what I want to find out. this is from the link in the first post and lists the differences...

"The Corolla Sportivo Turbo is fitted with the current 7A-FE engine, turbocharged and intercooled for increased power and performance. It developed 53 per cent more torque and 35 per cent more power than the Levin on which it based. The turbocharger, intercooler and auxiliary parts were developed in Japan but tested and certified locally. To modify the engine, the turbo is supplied with a host of extra parts including a revised ECU, exhaust manifold and turbocharger heat shields, revised front exhaust pipe, fuel injector and oil separator. To withstand the increased power and torque a TRD clutch and clutch pressure plate are fitted. Features carried over from the Levin include the ABS, rear disc brakes and safety features like the dual SRS airbags. The four-wheel independent suspension has been enhanced with a sports spring set-up incorporating a stiffer rating and lower stance for improved handling and increased rear grip. TRD brake pads with a better co-efficient of friction improve stopping performance."

I would assume those are all they changed but if someone could find out otherwise I'd like to know
