BOOM! Back from the dead. I was thinking about this build thread over the weekend and realized it has been like a year since I updated it. So here we go. Still not done, but a lot has changed!
1) After my tune date last fall with my twin setup, my drivetrain siezed up on my way around town. Turns out in my rush and excitment to finally drive the car, I forgot to put transmission fluid in it.
2) So I decided to just pull the motor/trans over winter and make changes I'd been wanting to do to clean it up.
3) Took the transmission to the local shop that does my work. Lucked out and found out that it was only the main bearing. A quick and easy 250 bucks later and she was all fixed up and ready to go.
4) I figured "What the hell, its out, lets try to clear out this twin setup and go single too" So I was able to part out the twin setup all over the world: Some to Australia, some to Canada, and some to Ohio. With this extra money I was able to fund my single turbo conversion over winter.
Single turbo conversion consisted of:
Full-Race T4 Twin Scroll EFR Manifold with 2000 Degree Coating
Full-Race Borg Warner EFR 8374 with 2000 Degree Coating
Bosche 044 In Line Fuel Pump
Custom made Vibrant material down pipe
DEI Titanium T4 Turbo Blanked
DEI Titanium with LRT Head Wrap for Downpipe
A whole slew of new fittings, lines, and additional heat dampers
I learned from my twin setup that the exhaust heat is certainly a downer on an RB26 swapped S13 to the point it was burning through my rear turbo oil return line pretty regularly. I didn't want to make the same mistake with the single so I kind of did some overkill on heat regulation. I also wanted to make sure the Downpipe could be removed without dropping the steering rack like I always had to do wit hthe McKinney Downpipe. So All around it was a win as far as I was concerned.
I also gained 60whp at the same boost over the twins with the same exact spool characteristics. The EFR's really are pretty bad a** turbos. Not to mention not needing an external wastegate (or twins for the divided like I have), no external BOV, no external boost controller....I mean it really cleaned up that side of the engine bay as you can clearly see from the pictures:
