OK, this thread got to be pretty long but I've narrowed it down to the EJ22T or EJ25D swap.

A final question for those who have done it before: deck blocking. Is it possible to deck the block without disassembling or is disassembly necessary? I'd rather not break it down unless I absolutely have to.

Thanks for the advice!

In your turbocharging scenario, what engine management are you planning to use?


The block halves need to be split to deck them.

Stock ECU.

Crap, if I split the block, then I'm basically rebuilding anyway. The advice is to avoid rebuilding the bottom end and just swap. But there's no way to deck the block without disassembly. That's a bummer.

I've never seen a running EJ that needed the block decked, and I've gone at least as far as headgaskets on nearly a hundred engines. You won't need to split the block or have the surfaces decked if you start with a runner.

Generally on an overhead cam engine, I avoid decking even during a complete bottom end rebuild since any of the material you take off of the block or head sealing surfaces affects cam timing.
