Small update. Went to Packwood for autocross this weekend. Borrowed some hoosiers.

The car is a ******* ROCKETSHIP. With hot hoosiers it hooks out of corners in 2nd at 16psi. And just takes off. Mind blowing speed. There was a slalom the first day that was fast enough for me to grab 3rd on the entrance, and then just haul *** through to the end. Hit 75mph at one point.

Car still smokes even with the new drain line. Guess I need to drill out the pan bung.

Hooked up the catch can to the intake. This is what it looked like after 200 miles and 20+ autox runs.




Not too shabby, I guess my rings are sealing ok?

Other issues:

Still get fuel starve. Need to deal with it.

Need to get a muffler in for the laguna pre mrls track day, well see if I can make it happen.

No videos, couldn't find my gopro SD card.

 

Thats awesome man! Glad you got a chance to experience good tires.

I wish my catch can looked like that!

 

I see you've now taken a hit of the

 

 

PUT ME IN COACH.

 

If it's any small consolation, I am pretty sure I am having the same oil drain issue.

 

waitwuuuut?

suddenly every other EFR on the site has an undersized drain?
next person should try a 2" ID drain tube. Or better yet, 3". Everything is better in 3"

 

I've got 3 more plans to try and solve the smoking. If none of them work then the turbo will be sent off.

1. @hi_im_sean is making me a custom drill bit to drill out my oil drain to .591" (~.03" larger than the BW requirement). Its stubby and should fit between the rack and the pan. Will suck to drill.
2. @yank has a new Turbosmart Oil Pressure regulator (Oil Pressure Regulator (OPR) T40) that he is going to loan me for a test. Should keep the oil pressure constant at <40psi, instead of the 74psi im seeing at redline (above recommended, below max)
3. Ebay scavenge pump. Last ditch attempt, will be a pain in the *** to plumb, but will be able to rule out lack of drain flow as the smoking issue.

 

the scavenge pump should 100% confirm if it's a drainage issue

 

Yup. Its also the biggest pain in the *** to setup.

1. $15 of tool stock + sexual favors
2. $40 of lines and fittings + sexual favors
3. $ pump + $$$$ lines + horrible to plumb

 

can't you just ghetto rig something up temporarily for testing? and use like the cheapest pump?

 

Maybe. But its really tight for space.

 

A 3/8" drain line going to a scavenging pump works great on my car for the rear turbo, and I use the pump to lift the oil and drop it into the valve cover. No problem. 3/4" gravity drain works fine for regular turbo. I think either approach would solve any possible oil drain problem on your car. I would not try a regulator, that seems dumb to me. Frankly I'd just to a 3/4 hose no restrictions dumping above oil level, and if it still smokes it's not the drain.

 

I have a 3/4 hose currently. Thats why I need to drill the pan bung out. So it has the same ID as the other fittings.

 

I just read you're going to drill it out to ~5/8 ID. What is it now?

 

Currently around .46". Borg Warner specifies no less than .5625" the whole drain.

 

.

 

Did you use the fittings supplied by Sav? I have my hardline kit still in the box somewhere but haven't verified diameter yet.

 

All my stuff is custom.

 

Ahhh okay, what kind of fitting is on the turbo itself? My treadstone fitting that attaches to the turbo is about the same size ID (.46") as your fitting on the pan.

Disregard I just found your post. Not a fun prospect to have to make that fitting...
