Incredible work.
I had to scratch my head a few minutes to follow the piping.

Look forward to some numbers, if the owner eve wants to post them.

Hi Nick, and thanks to all of you for the kind comments.

Honestly I wasn't real happy with the end result of this system. A lot of it had to do with the fact that I did it for a few hundred bucks for a friend with a VERY limited budget. The end result was that not enough time or money was spent in some important places (fuel management specifically) and that caused some problems (he blew the engine). He replaced the long block and ran it again with no other changes and unfortunately that engine starting having problems as well. I had him bring the car back to me for some diagnosis and to change the fuel management to an AEM F/IC and do some better tuning. After a compression test I found that one of the cylinders was bad so we stopped there. He ended up bringing the car to another friend to have the whole system redone and the engine rebuilt. He felt that the system that I built on the engine was faulty and that I owed him a new engine. Long story short I bought a new engine for him. Unfortunately there's a lot of resentment on both sides and the whole ordeal all but put an end to the friendship.

The moral of the story is:

1. When it comes to your job, don't do favors for friends. You don't get paid for your work, your friend doesn't get the service he deserves, and the friendship may be damaged irreparably.
2. When it comes to doing unusual, out-of-the box builds, make sure you have enough money, don't cut corners, and be prepared for setbacks.

As far as the subject of twin-charging, I think that it could still be done effectively but some things need to be changed to make better use of both the supercharger and the turbo. Also I would have used a larger turbo and found a way of combining the charged pipes instead of feeding one to the other. The bottom line is that the expense probably is higher than the benefit that you get and money would be better spent on a straight turbo build, unless you really want to do something unusual.

that sucks Tweak. U do good work ur friend started out cheap so he got what he paid for.

Your friend must not be too bright, adding a power adder to an already FI'd motor without proper tuning capabilities? What did he expect the outcome would be?

That's a real shame that it ruined your friendship. It's too bad more people aren't able to distinguish the difference between business and friendship. If he'd been a *true* friend, he would've respected you enough to pay you for your services. You're not in the business for the feel-good of it, ultimately, you have to make a living. He took advantage of you. And in the process, it sounds like it cost him a hell of a lot more money anyway than he would've spent had he just shown more respect and been mature enough to separate business from friendship.

Rest assured that one day when I show up on your doorstep with a 6th gen, I'll be able to separate the two!

That said, so who's gonna be first on here to show up at Doc's doorstep with twin chargers gleaming in their eyes!? Sounds like a really fun and challenging project!

Thanks Doc.

Sorry to hear about all that happened. That guy was not a "True" Friend at all. I wish everything would have all turned out ok. I'm really sorry, man.

I wish I had a 6th gen again, I wanted mine converted into a GT-4 so bad. I went to a show this weekend and a guy had a RX-7 converted to a JDM RX-7, I almost cried thinkin "I wish I could have converted my 6th gen Celica."

Thanks guys

His loss, i'd let you build my engine anyday!
