Im currently running a BSPT fitting off the rear of the block to a -3an line, then to a T fitting which goes to my oil pressure gauge and to my stock sensor.

Can I also use -3an line for the VTEC feed? Or is it too small? Should I run -4an off the block and to the head?

The thing is, the 1/8" BSPT off the block is TINY! I mean the hole in the fitting is like a -2an. I get 80+ PSI above 4000 RPMs which is more then enough to activate VTEC.

 

Gotta luv fluid dynamics and no ENDYN BBS!

#3 or #4, you'll never know the difference

 

1/8 is about the same as -4

 

Haha...Im having withdrawls here without the Endyn board ;-)

So youre saying it should be ok? I dont know...Im just paranoid, everyone uses -4.
Is the line just to provide pressure to kick VTEC on or does it provide oil to the head/cams?

 

iam to when is it coming back??
