Low mount turbo!

Toyota 503E.

The most famous and successful Toyota Race engine- the 503E was used in Toyota's Triumphant Championship seasons in IMSA GTO / GTP, Pikes Peak, Le Mans, and in the mid-90s Japan Touring Cup Championship. It is important to note that the 16 valve cylinder head layout from the 152E engine and the T block crankshaft saddle design were used as design base for this ultimate Toyota 4 cylinder Turbocharged race engine. The 503E represented the most powerful 4 cylinders in competition history developing over 1000HP in qualifying tune, 800HP for sprint races, and 600 for endurance events.

Dan Gurney ran the 503E Toyota 4 cylinder engine, between 2.0 and 2.2 liters, in his IMSA GTP cars. The engine was tuned differently for endurance races, sprint races, and for qualifying.
At the 24 Hour race at Daytona the engine in the GTP machines ran a little over 100 inches of boost for something like 600 to 800 horsepower; and at least one engine ran 127 inches for over 1000 horsepower, but I forget what that was in, maybe Millen's Pike's Peak truck.

From an Auzie site:

In international competition the 3SG has powered formula type cars that have been consistent international winners specially under the TOM'S Racing Banner. The 3SGTE engines in WRC won for TTE (Toyota Team Europe) several Championships for Toyota. It is also the engine used in the WRC Champion Toyota Corolla, set up to a limited 300HP.

The engine is very similar to the JTCC / IMSA Champion 503E engine- In fact the development of the 503 was the basis of the 3SG, in effect the 3SG was based on a racing engine! A 503 was running even before the first 3SG.

This lightweight 2000cc block and 16 valve head with Toyota lineage- is a must have for the old school Toyota camp, needing (wanting?) a modern powerplant. We have available RWD conversion kits to retrofit these engines for RWD!

With Toyota's introduction of aluminum blocks, this may be the last of the 4 cylinder iron blocks. This is important to note because current new generations of aluminum blocks will need major preparation to be able to reliably sustain HP outputs that this iron block will easily survive. For ultimate Toyota power in the 2000cc class the 3SG is the final answer.

One other view of the IMSA engine

More info regarding the restrictor for the TTE rally cars.

Toyota Team Europe has been banned from competition for the next 12months, and the points already gained in the 1995 World Rally Championship have been taken away by the FIA.

"It's the most ingenious thing I have seen in 30 years of motorsport." admitted FIA President Max Mosley after an extraordinary meeting of the FIA's World Council convened following technical reports on Toyota from the Catalunya Rally.

The cause of complaint was that Toyota had fitted turbo restrictors which were modified in three ways:

The restrictor was not sealed so it was possible to move it without touching the seals.

It was possible for airto enter the engine without passing through the restrictor.

The position of the restrictor could be moved so it was further away from the turbine than the50 mm limit permitted.

It was discovered that these irregularities were made possible by a flange which had a special hidden bypass device which was held open against a very strong spring. The hose which connected the restrictor to the turbo had a metal casing inside, and attached to this casing were catches which could secretly force open the by-pass flange to the extent of 5 mm.

Max Mosley explained: "When the system was dismantled, the flange would automatically close itself and remove evidence that extra air could have entered engine. This system not only allowed extra air which did not pass through the restrictor to enter the engine, but also the restrictor itself could illegally be moved further from the turbo.

"The hose was fixed to the restrictor by a jubilee clip. A special tool was then applied to open the device and then the device then gripped in the open position by a second clip. Both of these clips had to be undone for a scrutineer to check the restrictor and in the process of opening those clips the device snapped shut.

"Inside it was beautifully made. The springs inside the hose had been polished and machined so not to impede the air which passed through. To force the springs open without the special tool would require substantial force. It is the most sophisticated and ingenious device either I or the FIA's technical experts have seen for a long-time. It was so well made that there was no gap apparent to suggest there was any means of opening it."

The FIA estimates that 25 per cent more air was allowed into the engine than permitted although admits it's difficult to estimate how much more power that would achieve. An expert put it as high as an extra 50 bhp#65533;a considerable advantage when the cars are supposedly limited to 300 BHP.

TTE did not claim the device was legal but was represented by lawyers who entered a plea in mitigation. Mosley went on to say that the points Toyota and their drivers, Juha Kankkunen, Didier Auriol and Armin Schwarz had gained in 1995 would simply be taken away but others would not move up to fill the gaps.

The team would also be banned from contesting the 1995 Network Q RAC Rally and the 1996 World Rally Championship. He also stated that the FIA would not allow the team to get around the restrictions by entering under another guise and went on to say that there was however, nothing to suggest that the drivers were aware of anything going on.

According to Toyota the device had been devised at a "certain level" and the management knew nothing about it. The FIA dismissed this claim, saying that as a team they were responsible for all their actions.

He went on to say that there were indications that this type of thing was not happening with in other teams and praised those who were concerned with discovering the irregularity. TTE has announced that it is planning to appeal against the ban extending through 1996.

The absence of the team would weaken an already frail championship and leave it to a fight between Subaru, Mitsubishi and Ford with Subaru being the obvious favourites.

That tacoma looks scary to drive. Sketchy under power and brakes :)

My kind of car :D

It was still setup for dirt from pikes peak when it was at goodwood.

shame it was slower than the celica though.

The tacoma had the record for the goodwood for quite a while.

looks very scary id prefer the celica, jeez that tacoma pushes out some black smoke

nearly went in to the landcruiser at the end.......

My guess is that its tuned for the altitude it races at. Pipes peak is a long way up and goodwood is a long way down.

plus it was 9 years old when it ran at goodwood

great thread!

Something slightly different.

This is the BEAMS engine from a "S2000 Corolla" rally car, built by TRD/Neil Bates.

doesn't show the best bit. the awesome Intake manifold

theres alot of awesome on these engines.

Like all the carbon fiber kicking round.

back to JGTC, 3SGTE dry sump oil pump.

Trav, i must say, this is by far and away, the best thread ive ever seen on this forum, albeit the entire internets.

cheers

+1

this one is a bit if a odd one.

the guy who has this on his car claims it is a rare (6 of) carlos sainz manifold. the manifold next to it is a standard gen3.

im not convinced it is a rally type setup as the anti lag has been blocked etc and its using a external gate. my view is its some form of race gen3 item (not 503e) for some oddball racing.

as you can see its a much more performance orientated casting (obviously the external gate etc)

Hmm yeh doesn't look like a manifold from one of the factory teams, interesting item nonetheless.

Found some comparison shots
Firstly, gen 2 TTE vs standard blocks

And apparently a 503e block


Also some pics of of what's labelled as a 3S-GT JGTC engine, although looks like a 503e
