Using 2tgeu block for 2t/3t conversion, any reason why not?

[ToyTA22]

As title says, I have a late model 2tgeu block which I want to use for a 2t/3t conversion. Is there any particular reasons I can't?

Thanks in advance .

No it is the earlier blocks that you need to take to with a die grinder. The later castings will take the 3t crank without mods

Thanks for reply stidnam. I knew about the clearance issue. More so in relation to camshaft/ idler shaft bores, are they all still oil fed same as 2t block or need to be drilled. Also are the lifter bores machined? I don't have block nearby so can't check at the moment.

The dummy cam bores are the same so no problems there. As you are using a 2TGEU block it should already be fitted with the dummy cam you need to the xTGEU head. The lifter bores are machined from memory but no big issue as you don't need them for a xTGEU head.

If you are using this with a single cam head then you will need to knock out the rear 3 cam bearings in the block as for the twin cam head the rear ones are rotated to block off the oil feed for the single cam as the dummy cam is a lot shorter.

2TGEU block with lifter bore holes evident. Again pic stolen from Tore's ride thread. I can check my 3TGTE block to see if the lifter bores are machined when I get a chance.
