Stock turbo

Defi Boost gauge

banzai racing oil pan brace

Modified Oil Control Regulator to ~85psi



I am looking for what to do with fuel. My primary concern is to get it drivable and reliable. I am going to start saving for a standalone, preferable the new haltech platinum sport, but for now I need to ensure I have a safe reliable setup to drive. Can I just put 720s in the secondaries or will it be too rich?



I am considering an S-AFC or an r-tek 1.8. I have read about the S-AFC messing with timing so I am not sure how safe it is to run on my freshly built turbo motor. Looking for advice, thanks.

you would be ok if you had a way of knowing how rich/lean you are running(wideband display) and a way to adjust the fuel trim to make it optimal (S-AFC etc)

i ran 680's in my last t2.



power was up by 15-20% so i figured the 10% increase in injector was good.



on the car, it drove pretty well, seemed like stock but maybe just a hair fatter?

I have an Innovate LC-1 with the XD-16 gauge. I do not have a way of adjusting the fuel trim yet. Probably going to be 3-4 months before I can go standalone. Looking at either Power FC or Haltech Platinum Sport 1000. For now though, it looks like I will just have injectors cleaned and flow checked.

i'd put the 750's in, too rich is better than too lean

Amen, brother!
