WRC/TTE/IMSA/LEMAN/JGTC 3SGTE/503E engines,UPDATE

everyone has seen some of the stuff made for WRC over the years, be it Toyota or not. going to use this thread to post some stuff up.

first post is the alternator bracket redesign for the ST205 engines they used. they used dry carbon to make the bracket, awesome stuff indeed!

Why they didn't make something similar out of a different material for the production SW20 is beyond me.

why more stuff on the SW20 isent alloy is baffling.

Because alloy used to be way more expensive than cast iron.

Next up is the sump from a rally 3S engine, they don't seem to use a dry sump like the JGTC engines. Is this something to do with regulations? i don't know.







It has a bolt in baffle and gauze too.

Next JGTC type sump, setup for dry sump and made from Magnesium unlike the alloy rally type unit above.

also notice whilst not totally seperating each cylinder (touring car engines have seperate sump sections per cylinder to minimise losses etc) they have baffles in a odd box shape that you cannot see per cylinder, i don't have any pics with the windage tray out but this would be interesting to see.

thats awesome!

where do you find these ?

funnily enough i found all these on yahoo over the past year.

ive got some more to add soon.

Some other interesting things to note is the compression ratio differences of the rally engines versus the "503E"

8.2.1

vs

7.0.1

interesting stuff since they both run restrictors.

the Lemans setup 503E's made 680hp on what they call a CT26R which i will find and post soon.

also the 503E is 2140cc instead of 1998cc in most cases

Ill take the alt bracket!

Thats i thing on my cars diet list, simular to the hux racing one, next time im at dads factory (he has hundrewds of alternators and brackets from all cars) ill see what i can make up.

Nobody seems to know much about this but it's a 503E engine fitted to a SW20. To me it looks like they just fitted it inside the shell. If anyone knows if it actually is running around with this engine thatd be awesome.

im planning the same now i have a garage. Show us what you make up though.

ps. good to see your back working on the MR2!

Why did Toyota dominate rally but then get banned:(

This is why....

I've always wondered how they did it! Thats pretty ingenious! :O

hmm yeah that diagram lost me.

I do like the arrows that add up to 100 * ? %

looks kike they bypassed a 34mm restrictor

in simple terms there was no restriction:)

JGTC

They don't feck around do they?
Huge timing belt cover, wonder what its hiding?
That exhaust isn't anything short of chunky!
That turbo is a bit strange too, wouldn't mind a look at that.

more gear off the front might be the reasoning.

Is it just me, or does the exhaust housing on that turbo look like alloy?

sure does but it wouldn't be.

The JGTC engines also ran Quad Throttle bodies and a carbon plenum

I thought the intake was transparent at first :p

Nice brace for the idler bearings, 5 bolts for the adjustable cam gears.


Whats the wierd sprocket on the left of the crank pulley?

Dry sump pump at a guess.

so where do i buy one and how much...

and tot's that would be a well educated guess/whatthehellelsewoulditbe guess....

Haha, it could also be a mechanical fuel pump, however, I notice its got a very shallow sump, and the dry sump pump isn't mounted elsewhere.

Awesome thread!

no timing belt tensioner

Would be a beach to fit the timing belt!

Wonder if its a mechanical tensioner hidden somewhere else then? My mechanic thought the early 3s was mechanically tensioned. Could be wrong though.
