THESE HIGH FlOWS CAN BE OBTAINED THROUGH THE EXCHANGE SYSTEM

HOW IT WORKS IS ON THIS PAGE.....EXCHANGE SYSTEM

     There are many flaws and restrictions in the JDM ct20 twin turbo system which are the ceramic exhaust
wheel that areprone to break apart after increased boost is
demanded from the turbo or from old age. There is also the Compressor wheels
which are undersize for most power outputs wanted. With the
increase in these two on the turbo alone, boost creep is now
the problem, as the boost control is only done on one wastgate
flap between the two turbo's.

The best method of retaining the sequential operation of the
Twin turbo's of the 2jz engine and also keeping the factory appearance and
having performance to match a single turbo setup, if that is the requirement, is to High Flow the Factory CT20 turbochargers. This can be done with a very cost effective way that has been developed to get the most flow from the system by improving the flow in the restricting areas of the CT20 twin turbo design.
      
    
     Upgrades (supporting mods) which go with the
twin turbo high flows are larger exhaust system, bigger
intercooler and fuel injection modifications.
Higher upgrade methods available (below) are ported exhaust
manifold,high flow turbo,Ported wastegate and dual intake pipes.

All high flows suitable for sequentail operation.
(Highly recommended)

THESE ARE NOT SOLD OUTRIGHT.
EXCHANGE OR OWNERS TURBO ONLY

 

 

Here are the options for exchange and there prices - AUST $


Rebuild standard CT20 twin
  STAGE 1...................$1500 total

Exchange can be ordered or owners turbo built.

Includes:-

Steel CT20 turbine wheels.(INCONEL)
Fully overhauled including kit (new seals,o-rings,bearings)
Fully cleaned and dressed to appear"new"
Fully balanced including core balancing and speed testing.


 

High Flow-Basic
STAGE 2.............................$1850 total

Exchange can be ordered or owners turbo built.


includes:-

Fully overhauled (as above)
46.5mm compressor wheel
Steel turbine wheels cropped (inconel)
Ported wastegate hole.

This high flow is suitable for someone wanting to customize their own system as in fitting their own remote wategate and/or custom manifold. It still has very restrictive turbine housings but very good value. Without a modified wastegate or external this could cause over boost or boost spikes.


 

 

High Flow with wastegate improvements -
STAGE 3.......$2400 total

Exchange can be ordered or owners turbo built.


Includes:-

Overhaulled and high flowed as above with 46.5 mm Billet Compressor wheels
cropped inconel turbine wheels.
Enlarged wastegate valve(32mm) and large can heavy duty
  actuator (ct26) for better valve opening at lower Boost.
Controls boost well from 14psi.
Approximate output rating 280rwkw - 320rwkw (Based on 20-25 psi with a stock engine (unopened),with supporting mods and an average reading dyno)

Very good value for this highflow and simple to fit and tune the sequential system to reduce the "dip" between the first and second turbo.
Still has restrictions in the turbine housings, intakes and manifold.
This is the best value 2jz high flow on the market for true Good performance without any hidden issues or predicatble problems suchj as boost creep or spike or sequential issues.
