Anything new with this build?!?! Im very interested to hear your thoughts on the setup after driving and specifically your thoughts on manifold design? Would you change anything in hind sight? Sick build with nothing but props man! Hats off to you for building it yourself....

 

Nothing new really, have been daily driving the car through the summer. Coolant temps get high when its mid 90s with the a/c on. Going to try and fit a thunderbird fan on the car over the winter.

The manifold is still working nicely. The 6262, however, is not. After replacing the bearings once, I'm about at the same stage with this turbo again. It will smoke if the motor idles for too long (3+ minutes). I bought a borg warner 8375 (s360) to replace the 6262, also over the winter. Instead of short runners, I am going to make a longer runner manifold that will be for a divided housing as well. The short runners are ok, but I think the longer runner, divided housing will help it be a little safer with timing. But I'm done with precision. I've had 3 (sc34,sc61,6262) that have all had the same problem of leaking through the turbine ring seal. The sc34 had 50,000+ miles on it, so I don't have issues with that......but this 6262 has been used a little over a year/15,000 miles. I did change my return to a -12 from a -10 since I had spare parts to do it, but I don't think it will help this turbo at this point. -10 might has a .625" ID on the hose....but the diameter through the fittings is just under half an inch.

I will also not be recirculating the wastegates into the exhaust this time around. The downpipe/manifold are a pain to install/remove with the second, unplanned wastegate. And with everything being vband, nothing has a repeatable install position. I have to keep everything loose until its all together, then I can tighten things. Not a big deal, but when I make other things in the future, I'm going to try and avoid this.

But overall the setup works well...though the manifold can probably be more efficient.

 

Fair enough man and I feel ya on the turbo. I'm debating whether to go Borg or Garrett on mine and size. I don't wanna be replacing stuff all the time like that. I appreciate your thoughts on the setup. I plan on building a manifold in the next couple of weeks for my truck. Probably won't have this short of runners but was interested to hear your thoughts on it. Hope you like the new turbo!!!

 

So I finally got to the track a couple weeks ago. I ended up getting about 7 runs in that night. Mainly I wanted a trap speed as I didn't launch the car hard (I had to be able to drive it home).

First run of the night.
1st - 8psi
2nd - 10psi
3rd-5th 13.5psi







Best run
1st - 8psi
2nd - 12psi
3rd-5th - 14.5 psi





All my 60ft. times were awful. I was more rolling out of first than launching. There seemed to be a lot of heatsoak under the hood as well. The next setup will be coated or wrapped, and will be covered with some better heat shields.

 

Started working on the car here and there. I opened up a spare valve cover and enlarged a breather port to about 1.25".









I added an extra baffle that hopefully catches any oil on the lower half of the venting.





And making a manifold to replace my 6262 setup. The turbo is a borg warner 8375 (s360) with a .91 divided t4 housing.

















One wastegate located. The other will sit under the collector area of the manifold.









I tried keeping the turbo away from the headlight area as much as possible so I can fit an air filter in the corner. I cut the cross support to make locating things a little easier. I will replace it once the other main components are located. And I have to heat shield a lot of things under the hood.

 

Looking good! That downpipe is going to have a pretty serious bend in it it looks like. Any particular reason you switched to the Borg?

 

Wow. This build n fab work is awesome! Is this one on the build index?! Nice work!!!

 

In for updates.... Awesome work!

 

Yeah the start of the downpipe is going to be a pretty tight bend. I ordered a 3" radius bend, hopefully it will work out well.

I switched to borg because it was cheap and I could always upgrade to almost anything else. Plus my precision would smoke almost all the time. I'm hoping the turbine wheel isn't too big though.
