oil pump porting
 

I found some info on endyns site about increasing flow of the d16's oil pump. So im giving it a try on my zc, I worked on it for an hour or so last night. I think it turned out pretty good, I do have a little more cleanup to do but the porting is basically done. Anyone else try this? tips, tricks? How did it work out for you?

now take it apart and get all of that aluminum dust out of it before you blow your project motor

Re: oil pump porting
 

i did the same thing, and then put mine through the parts washer to get all the ---- out. can;t wait to put it on my car

"were already pulled over, we cant pull over any further!" <stupid troopers :8

The pump is completely taken apart and once Im finished porting the pump inlet to the pickup Ill give it a good shot of brake cleaner and than blow it out with compressed air.

If you take the plug out of the bottom of that oil pump and put a spacer on top of the spring you can also gain a few extra psi out of the pump as well ;)

Re: oil pump porting
 

I've heard a little bit about the spring washer deal. Any info on how that works?

Re: oil pump porting
 

brake cleaner is the ---- ..id do it hmt style ...just through it the dish washer .. ;D

where is the info on how to port oil pump

Re: oil pump porting
 

What's the benifit of running higher oil pressure?

Re: oil pump porting
 

Re-read the first post, then flick yourself in the nuts with a rubber band.

Hotrex did that I think.

I just went with the Z6 pump instead of the Y8 on my last build.

ohh noobie youll learn alot here ... www.theoldone.com

Ive never done it but I suppose you'd put a spacer either on top or bottom of the spring. The stiffer the spring the more oil pressure your going to have, figuring you have the correct bearing clearances. The spring and the little piston on the bottom are what regulate oil pressure. Once the oil in your oil main oil gallery has built up enough pressure it pushes the little piston in the oil pump up and it recirculates the oil back to the intake side of the pump. So holding the piston in place longer holds oil pressure higher.

But with proper clearances is added oil pressure really needed? Im not really looking for extra pressure, Im looking for more flow when its needed. Make sense?

Re: oil pump porting
 

yeah volume would seem to be more important than the pressure.

Re: oil pump porting
 

why did you go with the z6 oil pump instead is it better? please let me know because I'm building a y8 right now

Re: oil pump porting
 

Z6 is supposed to be better. I needed a new one anyway, so I went with it.

Only drawback is that there is no place for the dipstick on a Y8 block, and the Z6 oil pump doesn't have the oil stick hole. o you have to do regular changes, and have an oil pressure gauge.

Re: oil pump porting
 

You could also tap the skirt on the Y8 block, install a dipstick, and modify a longer than D-series Honduh dipstick to measure your oil for you.
