hi all I'm new to corollas and I'm looking for advice on what the best motor to put in my ke30 it must be able to bolt up to a ke55 auto trans and be legal to go straight through rego with no engineers certificates any help would be greatly appreciaated :)

Short answer is there arent any. You really need an engineers certificate for any non-standard engine that wasnt a factory option.

i wasnt after a non standard engine just a 3,4 or 5 k which is the best of these to use and will they straight bolt up to a ke 55 auto tranny

Then a 3K is the only answer then, as the 5K was never released in a Corolla, and the 4K wasn't available until the KE55 (I don't think so anyway).

cheers looks like ill just have to make my 3k go a little better as i want to keep my car as close to original as possible

Pretty sure in NSW you don't need an engineer's certificate for capacity increases less than 15%. Not sure what the regs are like in Victoria though

Yes as i have just recentlly found out i do need an engineers for my ke11 with a 5k. but i think it is just the Bad luck i coped a person that new what they were on about. i know of at least 6 or 7 corollas with 5k power no engineers, just my luck i guess and a cert is only $450 cheap peace of mind i think. Let you know how i go.

$450 for an engineers certificate migt be worth putting in a bigger motor afterall i assumed it would cost alot more

A 5K is gonna be your limit then, unless youve got about a grand to spend on a 7K.

5k sounds alot better than my 3k id be happy with a 1.4 litre instead of my 1.2 as I'm not after a big power increase just make it a bit more spirited

5k is 1.5 litre ....

my ke11 has a 4k in it and when i went to ge tthe rego check done the guy told me to just change the engine number on the rego sheets and say that i just did an engine swap instead of a conversion
