Would j37 dual vtec oil pump help? Any issues or problems

So what if I replace original oil pump on j35 with oil pump off j37 a4 or a2 (dual vtec engine)

Will vtec engage earlier? Or what will happen?
Eventually I might convert j35 to dual vtec
Later when financial crash starts in 2020 and everything will be cheap. 700$ for j37 heads is expensive for me

Not much benefit with the J37 pump vs our stock pump. Stiffer relief valve spring would be the benefit if anything.

If your serious about dual vtec heads, let me know what you want to spend. I have a J37A2 I need to get rid of.
