Brian Goble's Non-Sequential Conversion, Part 1

 

5/29/99

1994 Mazda RX-7, R2, Red (for more info, check out: Brian Goble's RX-7 Page)

For a variety of reasons, I am in the process of converting the stock twin-turbos from sequential to non-sequential operation.

The decision to convert to non-sequential was a relatively easy decision once I encountered a problem with my 2nd turbo, saw the "rat's nest" under the intake manifold, looked at the incredibly simple boost operation and plumbing of a non-sequential setup, and then drove a car with the non-sequential conversion.

The turbos are out of the car (along with a ton of other stuff) and many parts are ready to be sent out for modifying, polishing, and/or ceramic coating.

After everything comes back, a few blocking plates will need to be made and by then, my PRofec B, mid-pipe and pulley kit should be here and we can start putting things back together.

Super extra special deluxe thanks to Jim LaBreck for leading this whole project (and doing most of the work--not sure how that always happens). Also, thanks go out to Justin and Trev for their help too. Thanks guys! Almost all of this process is way over my head (but, it sure is a good learning experience).
