What engine

[mms]

Ive done a bit of research into the toyota 4age engine but still not 100% on what engine I have. cant really get a good look at the side of the block to see if its 3 or 7 ribs on it.

I take it that its large port? Heres some pics

hmmmmmm, can't really tell what block you have from this angle... but I am sure you have a TVIS engine, and if it hasn't been taken apart, or opened up before, it is likely to have 10 to 1 pistons instead of 9.4 to 1. I'm making that guess based on the T/B vacuum connections, and your engines lack of other vacuum parts.

very simple all non afm models in EU are running the 10:1 comp pistons.

Big port head and if its 3 or 7 ribs doesn't really matter there is a 99% chance you have a 40mm crank with 18 mm piston pins.

There is a not a valve cover that changes that

I am just wondering if this is just an ordinary engine or having good quality of engine. Let me know.

Note the oil drain to the rear of the head.

This indicates late model block.
Likely high comp pistons, 7rib, 42mm crank.




No oil drain (low comp block, likely 3rib, 40mm crank)



Note that there are many intermediate versions.
7rib low comp blocks etc.

Lots of info here.
Oil drain is easiest to see to determine block type.

i see there is a map sensor on the firewal

so i think it is an 10 to 1 comp. engine with T-vis.

3 rib or 7 rib..
