Was there a factory 7afte?

i thought they discontinued the 4a and the 7a block isnt that what the 1z and 2zz replaced ? its a ae112 seems it would have a different engine

not in other parts of the world..... hell, in australia there was a (low production) 'factory' turbo 7afe model that came out in 2000

This was taken from the following thread, http://www.corolla-racing.com/phpBB2/viewtopic.php?t=6614&start=0&postdays=0&postorder=asc&highlight=7afte at Corolla-Racing.com. Toyotaspeed90 mentions that there was a low production "factory turbo 7afe." Anyone have any details on this? Does it exist? I hadn't heard anything about it before, so it just struck me as odd.

it was in austrailia. 2000 model year only. i want to say it was like some 'gold edition' and they came painted only in gold.

i remember seeing an ad for them (like newspaper ad) online like 2-3 years ago

intresting.. i'd love to know the specs.

Ninety Four · Feb 17, 2006

The car it came in is the AE112R Corolla Sportivo, if I'm not mistaken.

"The AE112R sportivo was only produced in limited numbers...from march 2001. But It had the 1.8 7AFTE which produced max power of 115kW @ 5600rpm and max torque of 237Nm @ 3600rpm. Just going on what i have heard these figures may have been overstated..."

Taken from an Aussie Toyota website:

115kW = 156hp
237Nm = 175ft-lb

Decent specs... love the torque number, would have been a fun car...

hp could be better, but I wonder if the internals are beefed up? Sounds like a nice platform to start from.

ok Tweak, whens the swap

teevee247 · Feb 17, 2006

My *guess*, and this is only a guess... is that the internals would be beefed up, ever single manufacturer that I can think of that offered a FI engine has always touted the fact that they beefed up the internals to make it more reliable... in this case, maybe using some pieces from the 4AGZE? Would definitely be a nice starting point for alot of pre-98 Corolla's.

I remember you used to be able to get a Tom's Turbo Corolla with a 4afe
that's where our 'toms kit' came from, car looks so sweet

I wonder how many were produced... 156hp.. 5-6psi's? I guess the 7afe internals are pretty beafy to handle boost and still be under factory warranty.

edit:

Toyota Corolla Sportivo Turbo
It might seem that performance car buyers go crazy for anything that’s turbocharged – but the Toyota Corolla Sportivo is a notable exception...

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 (a reputable Japanese tuning company). 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 at 5600 rpm and 237Nm at 3600 rpm – but note that premium unleaded fuel is required to avoid detonation and extract maximum power.

Found a not so great review of it:
http://www.drive.com.au/editorial/article.aspx?id=9086&vf=1

The engine was based on the 1.8-litre four-cylinder, which used double overhead camshafts and four valves per cylinder. In its more common, normally-aspirated version, it produced 85 kW and was hardly an exciting powerplant.

But if you thought adding a turbocharger would transform it into a fire-breather, think again. Yes, the turbo did boost performance, but only in a conservative way. Power went up to 115 kW, which was nothing amazing.

More significantly, though, driveability did improve because torque was also increased. And since the turbo produced only low levels of boost, Toyota didn't have to do much to the rest of the engine to make it survive, so it retains all the off-boost performance of the standard engine. As such, it never produced that rush for which turbo engines are rightly famous, but neither does it feel flat and lifeless at low revs as many a turbocharged engine has. It feels stronger and fitter and more responsive to the throttle, but that's about it.

None of that makes it remotely exciting to drive, and it simply feels like a Corolla with a bit more urge (surprisingly enough).

A five-speed manual gearbox was the only one Toyota ever bolted behind the turbocharged engine, although an automatic might just have worked OK (they often do with turbos).

Bigger piping and mandrel bends would add some power. Better yet, a bigger turbo and/or more boost would hopefully get the car over the 200hp mark.

Here's one more site with good info.

http://www.carsales.com.au

Mechanical
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.

So from what I coul figure the Turbo kit were designed by TOM's and most of the OEM equipment (clutch/suspension/brakes) were upgraded with TRD parts.. pretty spiffy. But the most important thing here is it is proven that a stock 7A-FE can handle 8psi safely daily driven (with proper tuning). using a VF27 (IHI RHF4B) turbo. I've worked with IHI turbos before, they're most famous for being OEM WRX turbos.. from what I can figure out it is a small ball bearing turbo with a .63AR, ~400 CFM at 14.7 PSI, ~420 CFM at 18 PSI. Amazingly the CFM output compares to a T3 60trim!
