Silvertop 4age

[wilson_610]

As time gets closer the list is slowly gettin smaller on my new race car.

 

but now i have a dilemma i need some help on. i ordered for my S/T 4age a set of leads and timing belt and half a dozen other things but they all don't fit!!!

 

i did a little research and found that i have a motor from an AE92, not the AE101 as i have read about every where else...

 

is this motor good or bad. any difference?

 

more to the point is the wireing diagram's the same for the AE101 to the AE92????

Ae92 had a 16v smallport, Totally different from a silver top 4age.

 

100kw motor.

yes but all the items that I'm buying for the ae101 are all different to the motor i have. yes it is a 20v motor. for one the timin belt for the ae101 s/t has 97 teeth and is 25mm wide. vs mine is 111 teeth and is 19mm wide. plug leads were too long. dizzy cap is different and rotor button om mine isnt a button its a disc... so on and so forth

Pictures ?

 

The only motor to come from an ae92 is 4age smallport in Australia. Then there's the 4agze and 4age bigport but they are jap engines.

 

Disc sounds like it has a crank angle sensor, Is it at the back of the head or off to the side at the front ?

its at the bloody back... pain in the ass due to convertin it to rwd... and havent got enough dosh to buy aftermarket... car has to run in hill climb in 5 weeks... I'm off to the shed so i will get some pickeys for ya

Sounds like 20v if its at the back, Some one has put in a crank angle sensor which is good but its not from a ae92.

:y:

 

 

heres the pickys i got sent of the motor

[Trev]

Its a 20 valve.

That is definately a silvertop 20 valve 4age. From an AE101/111 corolla, Japan only model. To RWD it on a standard computer is very hard without firewall mods, 3 custom water fittings, etc.

 

It is a terrific motor as far as reliability and power from a small engine goes. They have a nasty power curve that just keeps building all the way to 7800rpm. Serious top end for an atmo 1.6litre. Beerhead has an adaptronic ecu and loom for sale to suit this motor, for only 800 dollars. If you want to run this motor in rwd without too many hassles, that would be your best bet, IMO. You really shouldn't mod or bash your firewall unless its a race only car, in a class that permits mods of this nature. The adaptronic will let you put a billet cover over the dizzy and use its pulses as a cam angle sensor and then calculate its own ignition timing from that. There are a few DLI converter boxes aound to make the standard ecu work, with a removed dizzy, but they are super hard to find and you would need to get new coils and igniters to make it work anyhow. The DLI boxes were made in short supply by Anthony Kellam to make these motors RWDable. I have only ever seen one, and it was sold over a year ago. You could talk to Yager motorsport about the water fittings. They are in Victoria, and don't have a web page, but they can sort you out and put you on the right path with a nice billet rwd water kit. Anyhow, good luck. Maybe the leads you got were for an ae101 4afe? Who knows. They are of little use to you if you arent able to mod the firewall anyhow. What is the part number of the leads you bought? What you may have is a blacktop with silvertop cover and the only way to tell this definitively is to pull the airbox off and measure the quads. They should be 50mm at the trumpeted end facing the airbox. Id say this is highly unlikely as the airbox is all silvertop too. Also, the silvertop 4age runs an airflow meter, which you will need to keep to put in the standard ecu, so a custom airbox is needed too, or a pricey map sensored blacktop ecu, which probly wont run just right from what I hear.

yeah what he said, you probably got the leads n stuff from a 4afe ae101 as they also are used in that chassis... its definately a ae101 20v what you have though. if you arent using the distributor which i think you're not, then the leads are going to be custom anyhow

[wilson_610]

hmmm good point. but from bell housing to the ridge where winscreen pissers run there is a f**kin huge hole there that i have cut to fit all the FWD CRAP that u need to make this motor run... i really can't afford the new computer at the moment but since the hill climb is getting closer i have to bit the bullet and use the standard ecu...

 

as for the leads i didnt get the part number off them but when they were in the hole. the dust cap sat about 1 inch above the rocker cover.

[LittleRedSpirit]

I'm sure you will sort it all out. Any questions just ask. don't forget about the search function, solves most of my problems.

[wilson_610]

well just to update

 

Dizzy cap is unknown what he ordered. but ordered correct one.

Got correct rotor button/ disc.

Have new ignitor and coil. because i have had previous trouble with the ignitors in my TE30.

Ae101 HD clutch and pressure plate are on the motor.

Input/ spigit bearing inserted in end of crank.

Have assorted S/S pipe and bends to reroot the water from the back of the block.

Just look for some thermo fans (2) prefured same size, to fit a suburu vortex radiator. y i used it is cos it is brand new and it came on the car we got for nothing.

 

next when leads and cap come. assemble motor and install in engine bay.
