Just for you. Confirmation that the overpipe will fit. It's even equal length!




Now to get this thing back together and attend a super bowl party

Working on a design for the tube to T4 flange transition. Going to have this part investment cast. Trying reduce turbulence into the compressor by having a gradual expansion through the bend rather than an abrupt transition right at the flange. This is the biggest part I've printed yet. Had a couple of instances where the print shifted a bit. I think the tension on the drive belt is just a bit too loose.

Do you use support material?

I do. This part needed a ton of it both inside and out. Really sucked to remove it from inside the runners. I think it would successfully print without any internal supports though. Prints like this are really tempting me to upgrade to a dual extruder so I can print the supports with a water soluble material.

Great work so far! subbed along!
If you don't mind me asking. How much are you expecting this setup to cost from start to finish?

That's a good question. And one I don't really want to know the answer to

But if I had to guess I would say about $10k. A lot of tool purchases and supporting mods included in this.

The main components are:
Turbo: $2,400 w/ turbosmart IWG actuator and BOV
Intercooler core: $300-500
321 stainless tubing and merge collectors: $1,100
Aluminum tubing: $300-$500

The rest is hard to add up. $50 here, $100 there an so on. So I don't really know lol.

Any updates??

Sorry, not much for updates. Just got home from a nice 10 day ski trip in Colorado. Why did I have to come back home to work? Will be traveling for work the next couple of weeks as well so probably nothing new for awhile. I have been talking with a few casting companies about the above part getting quotes and design suggestions to help with the casting process. Hopefully I can finalize that soon. I did get some presents in the mail today though..

Okay

How do you realise the oil reservoir? To be more specific - how "big" should this be? Im looking to go the same route like you but I will just mod the frontpipe with vband clamps to fit the turbo. I want to use the FA20DIT scavenge pump just like you.. Is this plug and play? We need a adaptor plate I guess - like the avo one.

I love this. Always love people who engineer their own stuff for their cars. Nice!

Now I want to get one of those for my 7064 efr! Glad you went the EFR route. Can't wait to finally see some dyno numbers one day!! Keep up the good work!

Not sure exactly on how big the reservoir should be. It really doesn't need to be very big. Just large enough to allow an additional port that is vented to atmosphere so the pump isn't pulling the oil through the turbo (cannot create a vacuum). The FA20DIT pump drive is a direct fit to the cam but the flange does not fit the head and will need an adapter plate like the AVO. @VeloxEric or @Mrc@ptuning should be able to help you out with this. If you aren't dead set on an EFR turbo or doing a custom job like I was it would be worth checking into the ptuning setup if you haven't already. They have a really good package that matches what you have planned.

On a side note I build a really cool temp controlled encloser for my 3D printer today. Its really just pieced together Ikea furniture with a fan controller, led's, and added structure so the printer doesn't shake it apart. But I'm pumped on it. Now I can run my printer even more without my girlfriend getting irritated with the noise in the kitchen.
