Twin Turbo Project

This page will chronicle the transition from a Paxton NOVI 2000 to a Cartech Twin Dominator T-70 setup.  The two T-70s should far exceed the power output of the NOVI 2000.  I'll also be adding a Vortech Igloo cooler and BigStuff3.

March '05:    I stumbled across this barely-used Twin T-70 kit on a local message board for a decent price:

Here are a few shots of one turbo:

There are a few drawbacks to this kit, but for the price I figured it was still worth it:

  1. The headers were designed around a car with manual brakes.  My car has power brakes.  I will be swapping to manual brakes as part of this conversion.
  2. The header flange is designed for a wide horizontal exhaust bolt pattern while my heads have a custom diagonal exhaust bolt pattern.  This means the existing flange will need to be replaced with a new one.
  3. The kit was designed around an air-to-air intercooler while I prefer to run a water-to-air.  I've already sold the air-to-air to help off-set the price of the kit, now some piping will need to be fab'd up to replace it and mate the turbos to the air-to-water cooler.
  4. I'm not 100% happy with the size and routing of the down-pipes so they'll be getting some attention too.
  5. I have no idea where the alternator will mount.  It's just one more thing to figure out once the headers and turbos are mounted

Here's a picture of the Igloo:

The BS3 is on order, I'll post up more when it gets here.

More to come as it's done.
