Why did toyota place all the fwd/awd engines from the mid 80's to late 90's slanted back at an angle?

Hondas are slanted too.

v8s are slanted as well...

Hehehe, just playing..

all d and b series engines ive seen, as well as 4g63's are fairly straight up and down

I used to have a 1990 Honda Prelude SI and the motor was actually tilted slightly forward. Probably for hood clearance. But Since the rear of the hoods on most cars is taller than the front, it would make more sense to tip the motor backwards. I believe that this is why toyota is able to have non interference engines whereas hondas, mitsubishis, etc... have interference motors b/c their head has to be lower to fit under the hood more frontwards where the hoodline is lower. Just an Idea.

Really? My buddies 1990 Prelude 2.0 Si is slanted. I forget the code of engine he has though.

a common prelude motor is H22

Its a B20A5, just looked it up, well, that engine is slanted so i dont know.

The 4/7AFE is not slanted back at all.

thats the most popular prelude motor, but thats from the last gen prelude. If its a 90 and has pop-up lights i could'a sworn they had f22's. And a b20a5 sounds odd....anywho, dont wanna get off subject. still, anyone have any input or fact as to why they're slanted?

..... f22's are in the ap2 s2k's i highly doubt that ludes of that time had that kind of engine...
and h22's are godly. ive always dreamt of two projects. a 3sgte swap or an accord with the h22 just like they have in japan =D

no...i thought the s2000 have a f20c, not the same by any means

yep, just looked it up, sk2=f20c

the ap1 had the f20, the ap2 has the f22c

As said its for hood clearance and aerodynamics

i dont give a turd what an s2k has in it, all i said was lude's may of had a f22, never said f20, or f22c, the C makes a diff in honda's engines. I think the f22 is even a single cam with like 105 hp where the f22C is dual cam and like 250hp and vtec

oh, my mistake. i didnt know ludes back in the day had f22, i thought i was just clearing up something that was foggy for you. honest mistake, dont flip out on me.

it's amazing how fast a good toyota thread can turn into a honda thread around here.

Slant or straigh 4 [or any # of cylinders] has nothing to do with being an interference engine or not. That is decided by valve lift, C:R and piston head design.

Slant engines are usually used so that the hood line can be lower.
Compare a 5th gen Celica to a same year Eclipse. The Celicas have a lower hoodline. Mitsu used straight 4s while Toyota used slant 4s [for comparable sized engines].
Lower hoodline obviously effects aerodynamics as well.

The reason A series engines aren't slant 4 is because they were originally designed for a Corolla, which had a higher hoodline than a Celica.
They happen to fit under a Celica hood because they have a shorter stroke, as well as having a lower sitting intake manifold plenum.

I figured it had something to do with the block,due to possible longer stroke used with the 2.0 and 2.2s
