all AE92s have "redtops"..however, early AE92s have the bigports even the valvecovers are red lettered, later 92s have smallports
ahhhhh that makes sense now.....i got a redtop head with red lettering and the blue top in my car also has red lettering:) clears one thing outta my confusion:confused:

beautiful.....
101.3hp = 92hp at wheels ...even better
this car has no power but she still moves, doesn't make sense...

new project will be once i've changed everthing that need to be replaced and lower the car and get rims and finish my system and my other car's swap and everything else it needs i'll get some CAMS for the ae92

it wont be till next year :(

okay i jus read this on http://www.geocities.com/MotorCity/Garage/8422/4age.htm



Later 16 Valve models (87.5 - 89.5 Red and Black Top, or post 89.6 Red Top engines) all face backwards, however it is my understanding that intake manifolds are interchangeable between all TVIS engines (ie up to 89.6 when the Red Top was introduced).
If you do not have access to a RWD manifold, or you have a post 89.6 Red Top, then there are two possible options short of fabricating your own manifold or going to carburettors - cut both ends off the manifold and swap the throttle body to the front of the manifold and blank the rear, or else cut the intake runners and weld the entire top half of the RWD intake on - assuming the intake runners line up.




SO ACCORDING TO THIS WE ALL HAVE RED TOPS.. JUS TO DIFFERENT VERSIONS,

USE THIS TO FIND OUT WHAT YOU REALLY HAVE

find what year your car falls under
ex. 87/5-89/5 is the 3rd one down
so go down to all the sections and the 3rd one is what your engine should be

Notes

AW is Mk 1 MR2, AE 86 is RWD Corolla GTS/Sprinter Levin/Sprinter Trueno. AE 82, AE 92, AE 101 and AE 111 are FWD only Corollas, Sprinter Truenos, Sprinter Levins, and Marinos etc.

AE 85 is 3A 1500cc SOHC version of AE 86, AE 91 is 4AFE Narrow Angle 16 Valve version of AE 92 etc.

MAP is Manifold Air Pressure sensor air flow measurement, AFM is measurement by Air Flow Meter.

TVIS is a set of butterflies that close off one of the intake valve ports below 4500 rpm to increase air flow and fuel atomisation. They are operated by manifold vacuum. Engines without TVIS (ie post 89.5 red Tops) have smaller intake ports.

All 4AGEs have the same exhaust ports and manifolds are basically interchangeable, but intake port design and size differ.

Red Top 4AGEs have an external oil drain at the back of the intake side.

4AGZEs and all post 89.5 4AGEs have a stronger block with 7 external ribs, bigger bearings and oil cooled pistons via jets that point up the bores.

Twin coil 4AGZEs have a crank angle sensor in the normal distributor location.

Inlet cam timing changes by approximately 15 degrees at 4500 rpm on 20 Valve engines.

There is reputed to be a supercharged 20 Valve (AE 111 car) but I am unable to confirm this.

The 100 kW 16 Valve, and 20 Valves all have a knock sensor, so it may be possible to run these engines on low octane fuel, however given the high compression of these engines, it is best to run high octane fuel so the best ignition advance profile can be used.
