Bmw E30 M50 swap HELP

[BmwE30M50Build]

Hi Guys,

Very new to the Bmw scene and the forum am planning a M5x Engine swap with turbo as a must. My budget is 10k for the swap and turbo install im aiming around the 400 to 500hp range but if budget requires stretching to achive disired power that can be done. My main question today to furthur my research as i seem to not be able to get a firm answer is what engine would best suit my build for the desired power and budget m50b25, m52b28, s50b30, s50b32 or the s52b32? This car will be used on the track aswell as the road less of a daily but used more than the weekend.*

Im sorry in advance if my question makes no sense there are just so many variations for the m50 and m52 engine and am quiet in the deep end as im not familiar with any of these platforms. I am quite capable of doing 90% of the conversion myself as this isnt my first engine swap but would appreciate your opinions and experiences with these amazing cars and engines.

Thankyou in advance
