I recently got offered a 4g63 n/t motor 6bolt motor out of a 91 eclipse for free. I plan on making the motor a 2.3 with a magnus stroker kit but I know the n/t motor isn't the same as the turbo motor. I am going to put a turbo on the motor and change the compression ratio to 8.5:1 but I need to know if I have to change more than just the compression ratio to put the turbo on it. I know there aren't any oil squirters on the n/t engine and that there isn't a knock sensor but I am still wondering if I should use this block. I do not want to put all this money into the engine and then have it just blow up. I'm planning on making around 700hp but I want it to be more than strong enough. I have researched this quite a bit and I haven't heard of many people using this engine for their build so I just want to see if it can be done.

A knock sensor can be added as can oil squirters (if you desire the squirters).

Alright well I don't know if this block has the knock sensor or the oil squirters. This engine is out of a 91 eclipse like I said, but its an odd car because it's a gsx. It might have the turbo block but it is definatly a n/t. Apparently from what the person has told me it is a mistake car that was supposed to be turbo but somehow wasn't. Has anyone heard of this mistake?
 
You can find out if it is the original block or not and whether it was a turbo block by matching (and if it doesn't match, then decoding) the VIN. This thread will help you identify the block: http://www.dsmtuners.com/forums/cylinder-head-short-block/390960-block-identification.html.

A non-turbo block can be built up just as easily as a turbo block; some actually prefer it because it lacks oil squirters. I seriously doubt it is a "mistake" car as the turbo can be pulled off and the engine can run without it. Feel free to update us whenever you find out for sure to prove one way or another.
