Question about FET's

[r3ap3r03]

hello, yea i have a question about the xmod evo/street upgrade fets i was looking for the 9910 and the 7324 FET from a electronic supplier so i get get them cheaper and i was told that thoes are obsolete, cannot be purchased anymore and there are newer versions available. Would i be able to use the newer version without issues??

i would also like to know if i need to separate FET's or can i just use one type . like lets say i only use the 9910 for example

thanks for your help
