American IMSA. Focusing on the engine as this is what the thread is about, however ill get a pic up of the car for you.

This is the lemans spec 503E also.

just for everyones info, this is taken from a post from some guy on MR2OC the other day.

what a douche....dunno how i missed that. was positive i'd read all the pages. must've missed half of page one at some point....WTF?

hahahahaha all good.

got some more to post. there is a 2.5 litre stroked 503E in Europe and the fastest 3SGTE/503E powered "car" in the world was a pioneer in the 90's in European drag racing (Finland). He set many records and couldnt be beaten in his class by anybody (alcohol fueled rail dragsters) unfortunately he got peeved at the governing bodies so now he drives a top fuel car (i wouldn't care about the 3SGTE any more either!)

This particular guy holds the record for the fastest top fuel licensing pass also.

ET-6.749 @ 323,73 km/h 201.2 mph.

This is the other 503E drag car.

prostock chassis, vp racing fuel blah blah, but........

it has a custom made billet 2.5 litre block! wth....

trying to track this down, though i doubt it has any water jackets.

ET-7.24

More stuff on the IMSA car.

ToyotaEagleMkIII-MF7

The MkIII’s engine was an evolution of the HF 89 power plant and mated to a March-derived 5-speed transmission via the cast magnesium bellhousing. As common practice, the oil reservoir was integral to the bellhousing. Steel A-frames (missing in the photo) ran from the monocoque rear bulkhead and either side of the engine to the shear plate which then attached to the bellhousing.

The Toyota 503E 2.1 liter single turbo engine wasn't installed fully stressed, instead relying on a structural cam cover and oil pan to increase the beam strength

Black and white ftw










just a general view. if you look at cylinder heads on race engines (including homolagation models) you will see similar aspects.

they all seem to run external water cooling per cylinder, high port angles and 4 bolt exhaust ports.
