The comprehensive 4age thread

Hey does anyone know where i can get a head gasket for my engine. Blacktop 20v

[kiran8977]

friend has a blacktop 20v and 5fwd box.....changed oil and no matter what, it grated from 1st to 2nd....anyone know what can cause that?

High rpm even worse....cruising and low rpm it doesn't grate

Clutch disc or clutch rubbers

i need a silvertop ecu or blacktop harness and brain for my car

[toyotajumbie]

Do you need a Manual or Automatic ECU for the Silver Top ?

[sandfly]

WTK if the 4age and the 5afe uses the same fuel pump.

I have a 20v silvertop in a AE91, but everytime I use the A/C I have to reset ECU since my RPM's drop real low. Any one have any issues like that with their 20v silvertop?

Had the same problem with my ST ages ago. Have a mechanic that specializes in these engines, sorted it out in ten mins. PM if u want his contact.

What is the OEM spark plug for the 4Age ST?

Have a box with the number on it I can look for, if you still need it.

These aren't the manufacturer spec, but these engines work better with these iridium plugs. I can't recall exactly why but I've spoken to a lot of knowledgeable people and these are much better for the engine. If you want the actual part number Toyota uses originally with these engines it's the one on the old plug I attached

Thanks bro

My cuz bought a 101 corolla with 20v ST
his mechanic threw away the original plugs and changed them with some cheap NGK.
He says the engine isnt performing well and he wants to switch back to the OEM spec.

I believe he should throw the mechanic away too. These engines rel temperamental if you screw them up, and obviously that person isn't too knowledgeable about them. I have a mechanic that deals solely with Toyota vehicles and been fixing these engines long time that I deal with if you like.

Can anyone tell me why the Crankshaft timing gear key would eat into the Timing gear like this? This is the second time this has happened.
20v ST

I really don't want this happening again since i cannot source these timing gears locally

[Jonathan_337]

Changing out the gearbox in my Levin. Wna get a slightly more aggressive clutch and pressure plate. Anyone knows where I can get one? Maybe like the stage 1 Exedy.

I'm seeing them on eBay but the car's down already so I'd prefer to get it locally. But if I don't have a choice, does anyone also know if the RWD and FWD 4AGE have the same clutch? And if the MR2 4age has the same clutch as the normal fwd 4age as well.

[Snixs27]

I have an 20v BT ECU (automatic) as well as the map sensor for sale.

[Jonathan_337]

Looking for the VVT cam gear for a 4AGE Blacktop. Anyone knows where I can get one?

[foss]

how easy is it to remove 20v blacktop?

[branz]

Any body plan to turbo a 4age 16V engine check me for pistons, timing belt etc. Have parts which were never used and I no longer need.
