What Engine Is In My Rolla?

Featured Replies

Havent you check the Vehicle ID plate for the engine code/type?

That photo is interesting in a way cause to me it screams out conversion but the id plate says its 4a-g

 

Is that your engine bay ? or one you found on the net for a similar motor ?

If you don't want to turbo it you'd probably have to get aftermarket cams for any serious gains. Costs a bit of cash to do the shims, add an aftermarket ecu for better gains if you go too wild with them. A factory airbox with a KnN panel filter will probably make more power that a cheap pod too. Apart from that you could try and tweak the cam timing to get better response and try running with nice quality plugs and leads.

It's a conversion - VIN plate says 4AC not 4AG (you can distinctly see the lack of an E). That, combined with the 3-bolt strut tops and lack of strut brace tells me that this was an ordinary 4A-C powered AE82, not a factory-4AGE Twincam model.

 

And to add extra info/narrow it down, it appears to be a 3-rib bluetop bigport too (intake air-temp sensor on the plenum)

 

To the OP, if you want information on 4AGEs in FWD applications, head to either Twincam.info or AE82oc.net, both focus on FWD Corollas.

thanks very much for the help guys :)

anyone know of any guides to cleaning up the engine bay? (yes the pic is my actual engine)

a 0.8mm TRD head gasket might help things a bit
