So i'm planning a turbo swap for this winter, and its time to start hunting for parts. I still am not sure weather i will be finding an l28et to drop in, or turboing my existing motor. Anyways, i found an l28e locally, from a 1980, with a n42 head. The price: a 24 or rickards. Sounds like a good deal to me, but i'm not to sure how usefull the motor would be to me, especially considering the hassle of transportation and storage. From what i (re)searched on hear, the the p79 head thats in my 83 cannot handle boost, something to do with a coating in the exhaust ports. How does the n42 compare to the p90 performance wise?
And lastly, would this motor have egr? I am looking for a non egr intake manifold so i can clean up my engine bay somwhat. Plus it would be nice to have a spare manifold, so i can get started on cutting out the webbing, polising, and adding a 60mm tb and billet fuel rail.
