97 Eclipse

Hi guys, Mike here. So if you read my profile or my introduction thread you might already know the backstory of my car but if you didn't, in a nutshell: car had 2 owner, broke down by the 1st owner, and I bought it still not running.

So this will be the backstory after I actually bought the car. (Will be linking images if I find out how to do that)
So I bought this 97 Eclipse to a mechanic. He had had this in his shop for 4 years and never fixed it. The car was supposed to go to his son so he bought the 2nd engine but that engine also had a bad crankshaft and he ended up losing interest and so did his son. So I went there and bought it from him along with the second engine aware of the problems but I have this dream so whatever.

As I was about to go to a shop to try and salvage any of my 2 crankshafts I found a good deal on a Plymouth Laser RS that had the engine in a very good shape.

What I didn't account for was that the engine's dimensions were different. As you guys should know but I didn't. the 6 bolt block is more robust on the inside than the 7 bolt block. And here they are:

To the left you have the 6 bolt block and to my knowledge it's in mint condition: 150 000 km on it 15 years stopped in the woods but it was still good.

On to the crankshafts I have some pictures too:

Here you can see the 6 bolt crankshaft, looks good, I have nothing to point out but if you have I'll be happy to know about it.

This is one of the two 7 bolt crankshafts and yes, both pictures are of the same crankshaft. I admit that they didn't have that rust to them when I got them but some months have passed since but for what I've been told, that little bit of rust isn't a major thing.

So the second 7 bolt crankshaft is here and it's a little better than the other one because I think but it's still in a pretty bad condition.

Now towards my real problem where I'm stuck right now: the crankshaft's rev sensor:

As you might know these too covers in the picture are different: 7 bolt on the left 6 bolt on the right and as you can notice the 6 bolt one doesn't have the place for the sensor and as you for sure know and I didn't, they don't fit in different blocks.
Now my real problem is this bugger here because I don't know if I can just ignore it and nullify the sensor to put my 6 bolt in the 2g or what I have to do to make it work.
I know for sure that people put 6 bolt blocks in 2g eclipses so I figured it shouldn't be impossible but I've searched many threads and I can't find the answer to this specific thing.
Even asked a youtuber about this problem in his comment section and his answer was: "if you have a non turbo engine you can't". No disrespect to him at all, he his making a gs-t to gsx conversion on his 2g (which I'd love to do on mine if I can't find any gsx in europe) but I was a bit sceptical to his answer. If you can with a turbo, then you should be able with NA engines. But I might just be wrong and that's what I'm trying to find out.

That is all for now, will be posting some updates as soon as I have some. Thank you in a advance.
Cheers from Portugal.
