im building a dart block... b20 bore .020 overbore standard deck height... my question is which vtec oil would be better? b16, gsr or type-r or are they all the same? the only difference my machinist and i saw were that the 94-95 gsr pump was a different part number... any differences between the type r or gsr? thanks

 

i dont think that there is a difference between 16 18c and 18c5 just make sure and use a vtec oil pump.

 

i think they are all the same too...

 

ok.. thats what i thought.. just needed some assurance... thanks!
