question about 20v silvertop models

[corollamadness]

I hear there is two silvertop 20v engines one is the 91 model one and the other is the 93 model facelift one.

Now from what i have already heard the 91 model came with 2 throttle bottle linkages coming off the accelerator cable while the facelift model only had one is this correct. If so what other ways can these two engines be told apart and what differences do they share. I hear the 91 model ones are slower.

I also heard that the 91 models came with the C52 transmission and the facelift one came with the C56. Just by looking at a C series box that is not in the engine bay is there any way of telling C52 from a C56?

do a search on the site, the cars have the same computer and almost everything else is the same, the facelift "may" have the teardrop inlet manifold vs the circle and cutout one, but this is un-confirmed

the ECU's are not the same.... I can supply pics if need be (they looks slightly dif inside...

pre facelift:
89661-12770 175000-4623 12v
facelift:
89661-1A190 175000-5761 12v

Thanks guys will do a search and if i have anymore questions ill post up.

yeah the later ones have quite a few differences, manifolds and ecu being the main ones im aware of.
as far as driving them goes im unsure of the performance difference, but iv been told by a few good guys who have played with them that the later has more potential for more power, due mainly to its manifold.

Sorry guys did not have to much luck withy searchs as i have no idea what to use as a search word i tried a few variations and got a cluster of topics and this was only a search in the tech section. When i have some time i will have to try and sift through it all.

So would anyone know if there would be any adverse affects to the engine if i ran the facelift model 20v computer on a prefacelift model. I ask this because i'm quite sure that is how my car is been run at the moment.

wont be a problem think it may run slightly ritcher (unsure....)

Probably will run ok because it is afm. The little more air flow you will get by the better manifold will be picked up by the afm and compensated for.

What i really want to know is do the facelift model 20vs all come with C56s and do all the prefacelift 20vs come with C52s.

If there is any way of telling the difference between these two gearboxes i would like to know especially since i have either a C52 or C56 sitting in my backyard and want to know how i can tell what it is.

Thanks guys search came with nothing that could really help me.

[Mr Revhead]

easiest way to tell is to put the box into either 2nd or 3rd and work out the ratio, 2nd and 3rd are about the only differences between the two.

im fairly sure that preface lift was c52 and face lift is c56

the facelift has only one throttle wire thingy not two and the trumpets for the inlet(inside the plenum)are teardroped shape eg start bigger then get smaller and have a nice little lip on them i am lead to belive that the valves adn the cams are set up slighlty differently, i had a 93ae101 and my mate had a 91 model,same other accessories ie pod and exhaust and mine used to dust him, even when we swopped cars

ive got a 93 levin, and the build plate has C56 4 the trans. On the road it does 103Km/h in second and 142Km/h in third, (clipping the limiter) on stardard bikkies. Or at 50Km/h second is 4000RPM and third is 3000 RPM If some one suplies the 91 levin specs as above, your gear ratios can be compaired.
