The orbit pump, how large is it? What will your oil clearances be? Might very well be too much pump.

This is the main concern I'd have too.

I'm not sure how hard it would be to fit a Walbro 400/450 in your vehicle since I don't know what model it is but if you can fit one you'll never run out of pump. Depending on your goals the dw300 may be fine though.

Dawg stick with OEM (10mm for non dual AVCS heads) oil pump unless you are revving it to 9k, keep it simple

Depends on your clearances.

I have SAVCS and my mains are at 0.0014-0.0015 and rods at 0.0020-0.0021 I have to upgrade to an 11mm oil pump (which is now in the mail )

My hot oil pressure at factory idle yesterday on an 83F day after my drive home with 2 WOT pulls it was at 14 psi with 20-50 oil.

I need an 11mm and I am kicking myself for not putting one in when I had it all apart because I listened to the gospel and it bit me in the ass because now I have to take it all apart.


OP your clearances are crucial to choosing a pump.

If you have clearances similar to mine a 10 mm oil pump is not enough IMO.

I had a 10mm on my SAVCS build too and also ending up having too low of oil pressure (clearances are little tighter than yours but not much) so I also am stepping up to the 11mm. Isn't the Orbitz racing pump a 12mm shimmed something or other though?

I believe so.
There is tons of 12mm oil pumps on ebay cheaper than 11mm oil pumps. I did a bunch of reading on them and saw that they have high rpm oil pressure issues.

It is frustrating to have to change out the oil pump because of people saying that 10mm is enough for SAVCS, heck I used to think the same and say the same. I think from now on any build I do it is getting an 11mm oil pump. The chance that you're going to heat the oil to extremes is pretty slim. Same with aerating it.

I messaged my engine builder for the oil clearances he set it at but he hasn't responded yet. Once the motor was finished he said he felt extremely good about it. Everything fit perfectly and all the clearances were perfect. Compliments to the machine shop as well. And before you start questioning the shop it's a very professional business in okc. He's built several high hp wrx/sti (+600whp) that last. That's why I went to him and my tuner strongly recommended him.
Now I was actually going to use an oem oil pump but he insisted that I get a acl Orbitz Racing oil pump. He stated that oil was everything and when running a high hp motor why use a stock oil pump. He said he uses this oil pump on most high hp builds with no problems tuning. So I guess we'll see what happens.
It's all going in a 08 wrx hatch. It'll be tuned on e85 and expected power will be between 475-525whp. I believe the fuel pump will also be ok.
What do yo u guys think about the injectors? Stay with the Ev14 1200cc or get the new fic 1650?

Any other advice or recommendations will be greatly appreciated. Any thing else I should add on?

Once the engine builder responds I will let you know the clearances. But like I stated...he insisted that I get this pump so there must be a reason
