This is a hypothetical question.

Say someone had a 05LGT turbo and the block has a problem and needs replacing.

Can one take a ej22t block (stock pistons, cranks etc) and place the intake, sensors, heads, etc from the ej25 and then put them on the ej22t and then install back into the LGT.

what won't work, cam/cranks sensors all work on the ej22t block?

also, is the 05 auto tranny going to line up with the old ej22t block housing/

 

thanks

Yes, but you will only use 4 out of the 8 bellhousing bolts and will need to use the gt crank trigger sprocket. Some headgasket work will probably need to be done, usually drilling coolant holes through. Check "built motors" on NASIOC, they have a fair bit of info.

It'll work. Everything above is correct. The ECU will need a retune. It will start and run on the stock tuning.

so drilling coolant holes thru the head......

not using some of the transmission mounting holes

and a ecu retune

 

 

Thanks

In regards to the machining / drilling of new coolant holes, thats just in the heads, and can you explain a little more

 

on the ECU retune, is that necessary what does that do

 

thanks

No, just the headgasket. The closed deck block has less area exposed for coolant to flow through, so some of the coolant passages on the 2.5l head won't line up to anything. Drilling a couple holes in the headgasket (with it clamped between boards usually) will allow enough coolant through in the right places. There's pictures of where it needs to be drilled on NASIOC.

sweet.

thats easy enuf.

 

now, the ecu portion?

 

big thanks on answers. this is still in the hypothetical mode.
