WIX are one of the most popular and attractively priced racing filters, not to mention readily available in most locations.I’m using a K&N filter now, but I saw the Wix was highly recommended when I started researching this topic. Thank you for the heads up on which I should use.
Again, I would discuss with the engine builder what filter he prefers and would like you to use.
There's two camps and trains of though on filters, some like the higher micron/gpm rating, some like the lower micron for fine filtration, it's a fine balance, depends how the engine is built and being used and in what environment.
If the builder is using large clearances and incorporated a HV oil pump and recommends 20W50 oil, I'd use a racing type oil filter like the WIX 51061R, 28gpm and 60 micron.
Can you use a normal oil filter, yes, but your engine specs/setup you may be on the relief spring and bypass mode most times, and you are not filtering squat like that.
