Building a Twin-Turbo Isuzu V6 for a Mazda RX-8

Mazda RX-8 with a twin-turbo Isuzu 6VD1 V6

A reader contacted us to share their unique project. They are building a 3.2 L 6VD1 V6 from an Isuzu Rodeo to power a Mazda RX-8. They will boost the engine with two Garrett T25 turbochargers from a Nissan 300ZX with a goal of 400-450 horsepower. The engine will be mated to a Pontiac Solstice transmission with an Isuzu Trooper bellhousing, tail-shaft from a 1994 Rodeo transfer case, and Chevy Colorado slave cylinder. The driveshaft is from a 2000 2WD Rodeo with a rear u-joint from a 1990 Dakota and RX-7 driveshaft flange which connects to the RX-8 differential. All told the project will use parts from 15 different vehicles. We will continue to follow the project’s progress and publish updates as we receive them.

    Hi guys, I’ve done heaps of reading about this and followed the build thread accross a couple forums but the author and forums just went dead and we never heard if it got completed. If there is any chance you may have a way to contact the owner (email will even do) I would love to be able to talk to him and get some info as I will be building the same motor just in a soft vehicle and for a higher power goal. Cheers
