Hello!
I don't get you sir....!
You Said its Genuine engine is Twin Cam16v and not 1600cc :S.....
how can it be possible....! this 86 Corolla came with either 1.3l 2E(12v) engine or reconditioned ones came with 5AFC 1.5L...!
1.3L engine with Twin Cam 16V...i don't get it...
Toyota have 4E-FE engine which is 1.3L + Twin Cam 16V but it did'nt came in 86 corolla...! it start to come in AE100 95 Corolla Indus Shape..!
This Car from looks Interior and Emblems looks 86 GT to me that came with 1.6L 4A-GE Twin Cam 16V Engine...!thats why i said it might be 1600cc earlier...!
if you swap it ..i can't say but this car can't be 1.3L + Twin Cam 16 from Factory....thats for sure...!
you better show older engine pics and new engine pics...!
that might solve misunderstanding...!!
This is how 4AGE 1600cc Twin Cam 16V from Orignal 86 GT looks like....!
