Lucifer gets new Turbo setup!

[Sleeper]

I'll restate what I mentioned when you first started this project. A properly tuned, good running, stock b6t will be faster than all these parts you're throwing together. I've built and raced a lot of turbo cars, I've got plenty of experience when it comes to setting them up and I've got a shelf full of trick turbochargers and tubing and I'm a certified welder, but my track car used a stock b6t. That says something about that engine.
A well built B6t Festiva will be almost boring to drive. They don't have crazy TQ steer, or wheelspin, they are quiet, and the boost comes on so smooth that it's hard to tell it's a turbo engine. These are all signs of a balanced package, a drivers car. To comprehend that this vehicle has 3 times the TQ that it rolled off the assembly line with, yet feels more refined and easy to drive.... Mind blowing.
If you take the time to appreciate a well balanced car, and focus on honing in your driving skill, you'll never go back to your search for dramatic uncontrolled and poorly tuned power. There is no substitute for dancing a car on the absolute limit. A well built b6t Festiva is a rare kind of package that makes this level of driving seem effortless. It disturbs me to see so many cars that are so close to this level of automotive Nirvana not being set up to their full potential. I miss my B6t car.

Thanks Charlie for this post... I have always felt this way about a b6t festiva swap... but is really nice to hear from someone who has done a bone stock b6t swap and loves it. When I source my car and parts I plan on doing exactly what you did with your b6t festy

I didn't say back pressure is bad. I said back pressure and more boost is bad. As I understood it, you mentioned controlling the boost creep with back pressure and then turning the boost up. That's a time bomb waiting to explode.
The stock b6t manifold is a much better design than a log manifold. Just have a qualified welder put an external wastegate flange in where the O2 hole (and cracks) are now. This is a job that should be done by someone who is experienced with welding cast iron and cast steel parts. With an external wastegate, you would be fine with a VJ11/14 hybrid. The IHI RHB5 turbos are some of the most reliable turbos ever made, but they don't handle over boosting and surging very well (basically, people who don't I understand turbo systems destroy them, not hard use).

Another question i have is- How bad is the stock exhaust mani? I could have him build me a log style manifold! It would really help me out with my to big of a turbo (i think)

[mikemounlio]

Advancedynamix Aside for going back to a normal exhaust what can i do o make my fender exhaust work better? I tried adding a neck down on the inside once and it helped to hold the boost much better and you said back pressure is bad. So do i need back pressure or not?

Should i go back to my normal exhaust or make the fender exit work better?

I have a friend/pro welder at work that is opening his own exhaust shop he said he will build all my stuff for the price of materials. He just wants to get his work out there and my car would be a good start for him. He welds very good! So it would be a major step up from what i have now.

Good to know. I hope to find some small dom tube local and make a harness bar this weekend or something. Still have to finish the passenger side seat mount.

[Advancedynamix]

You can have up to 20 degree downward angle on shoulder belts without problems. It's okay for the seat belt holes and harness bar to be slightly lower than your shoulders, but more than 20 degrees will be more apt to compress your spine.

[mikemounlio]

No harness bar yet so lets just hope i dint wreck it. I would hate to be shorter.

Actually my shoulders are like 2 inches higher then the holes on my seats. So no matter how i mount the belts im gonna get a compression. I will make the bar so that i get the best angle on the belts as i can but i can only get it close.

[mikemounlio]

Still didnt get the diverter valve on. I had to take a trip up north to pick up a car with a friend. I did have time to get my seat in tho. I love driving the car so much more with some nice seats in it. They really help the race car feeling.

I did adjust the bov and it helped me out a bit. Not much tho. I hope to do some good work on the car this week.

Im working on getting stress relief on the road again. I want lucifer in the garage as much as i can

[Advancedynamix]

He needs a Subaru wagon for the winter. It would be a shame to see this solid car exposed to winter driving. Let it eat a Subie instead.

[bhazard]

You're driving that car in the winter?

[mikemounlio]

Just placed the order for my tires. I went with the econo tires again. I dont have my fender flaers yet so going 185 might need to wait a bit. Ill go to the 185 55 14 federal 595 come summer. No need for that kinda tire in the winter and cold months.

The tuning is all messed up with your BOV vented atmospherically. Also, a diverter will let the charge air build velocity while your under partial throttle and when it closes (when you open the throttle far enough to reduce manifold vacuum) you have boost much faster. Boost pressure is a direct result of air speed. That BOV is a bad setup.
All this, combined with a poorly sized turbine will provide you with bad performance.

Bad performance is very true! Once the turbo is going its good but it could be 10x better then it is now i think. BOV has to go...
