That all depends - how far down the rabbit hole do you want to go?

Easy answer is no - not using the EA81T's computer. It does not understand the hot-wire MAF system.

Now if you go to the EA82 hot-wire MAF computer you have other issues - like injector and throttle body fitment, Idle control, etc.

If you go stand-alone like MegaSquirt then you can do whatever you like using whatever parts you like. Which is actually a much better option than trying to use an entire system from one year or another so a stock ECU can run it - this way you can pick and choose the best parts from all the years or the parts that will fit with the least complications IE: injectors in the heads vs. in the manifold, etc.

Short answer is no. Intake manifolds are very different as well as heads and MANY other parts. I suppose with enough time, money, and talent you could do almost anything but IMO this just isn't worth it.

@GD
EA82T heads and intakes are dual port vs single port on the EA81T, correct?

Here are some pics of the EA81T I am currently working on for reference.

if you have a complete ea82t donor car, then, yes, you can.

you will have to make a mod ti the corssmember. There are some specifics to know, but it is not hard to do. Some will say ea82t is worthless, others will say go with an ej22 for the effort. some are fans of the ea82

are we talking about vs an ea81t, or just putting an ea82t with ahrness in anea81 body? ea82 motor fits in ea81 body.

True. If you're gunna swap that much, might as well go with the EJ route, even the ej18 has close to the same power as an ea82t. But it matters where your loyalty lies.
