do you "have" to have a turbo-back exhaust if you're putting a turbo in the car? or you can just use any type of exhaust? how about supercharger?

 

You get better results HP wise if you do a complete turbo back exhaust, but Greddy ran it through the factory converters. Well here are the last few pictures. For some reason it did not want to take them all last night.

And the last pic on this project. Except for a dyno which will now have to be first of next month. After this next mod will be motor work and NOS

 

Hey Spaz,

This is amazing. Fast install. I've been doing my own install and i'm not done yet. Will hopefully have it done this weekend. But you're install was fast.

Looking Good

 

5 days, 6-10 hours each day, and greddy said 20 hour install. I think not. I have a couple of exhaust leak issues to still take care of and I am getting this wine from 2.5k - 3.5k If anyone knows what this might be drop me a line. I thinking I might have bend the gasket to the plenium and it's leaking. Good luck with your project !!!!

 

Thanks for responding. How do you know it's a exhaust leak? Just curious so I know what to look for.

 

SPAZ!! Congratulations on a successful installation. I admire your determination, and skill in getting that thing done so quickly. Great pics. I have a question for you.

What were the three most difficult aspects of the installtion process? IE...what took the most time...blood...aggrevation..etc. Thanks for the inspiration.

 

I can tell you splice in new injectors were not one of the three....

1. Turbo

2. Another turbo

3. Turbo again.....

 

I can feel the air coming out were the wastegate meets the turbo and the manifold. Real bad design if you ask me. I might have a shop reweld the wastegate flange on a angle and plug it were it use to run into the exhaust. You can also here a burble under the hood.

 

I would say that the hardest part was putting on the manifolds and the turbos. Some of the bolts are just next to impossible to get. Don't plan on torquing them down to a spec, you will never get a torque wrench in there. then I would have to say the piping comes next. All the pipping on the right side touches one thing or another. Real tight fit.

 

Thanks for the tip. I agree that is a bad design there. I haven't started up my car yet but will check that area again before doing so.

I finally had a chance to dyno the final product for anyone interested. The first pic will be of my cars second dyno against a stock 350z that was done on the same dyno for comparison. the second pic is of the 2 dynos that were done on my car at 8psi. these dynos are SAE corrected. altimeter was set to addison airport which is 1 mile away.

 

pic 2 of the two dynos that were done

 

Very nice looking dyno A/F looks to stay in good shape as well. You are using a TS flash to a 8 psi boost correct? What are you using the Profec E0-1 for? All I can think of is to adjust the boost level but that's about it since the fuel side is based of the TS ECU flash. Did you fix the exhaust leaks?
