That explains a few things too. It'll slam onto boost & would make for a difficult car to launch at the strip due to the on/off way in which is makes power/boost.
 
No reason to ditch it, but slightly poor form to the seller for falsely advertising.

Some more progress to report.
The engine is back in the car, and most of the hard stuff is done. The fuel lines and FPR have been relocated for the new fuel rail system, the CAS and COP wiring has been partiallly completed, the throttle cable has been extended and mounted to a custom bracket on the plenum, the holes in the boot firewall (from the original A2W IC) have been patched up, etc.
 
I love how easily the fuel rail and purple ID2000 injectors can be seen with the new plenum:

 
Here is the new PWR front mount heat exchanger for my A2W IC system. The core size (without the end tanks) is 480x230x32. PWR custom-made it according to a drawing provided by MRC. The air conditioning system is retained. I have a copy of the CAD drawing by PWR, and the drawing number is "PWH62619". So, if anyone wants the same heat exchanger, you can just call PWR and provide that drawing number.

 

 

 
*EDIT*
I got some photos of the Johnson CM90 water pump installed (these photos were taken at a later date after the above photos of the heat exchanger were taken)...
 
This shows the pump location, and where the horn was relocated on each side of the car:

 
The specs sticker on the pump (it might be too hard to read after the image is compressed):

 
Looking down through where the left pop-up headlight normally goes, with the front of the car at the top of the photo:

 

Very nice! Love it

MRC just sent me a few photos of the OS Giken R2CD twin plate clutch.
 

 

Nice setup, I have the same W2A core and a similar build but a very different turbo  
 
I would recommend anyone to buy that PWR heat exchanger, I used one of the frozen boost ones and the mounting was a pain in the ass.

Looking very good mate.

your car inspires me. what did that pwr rad cost? i have a thick pwr radiator already, pwr are top quality.

Looking forwards to seeing how the HE sits with the front bar back on.

looks sweet man, nice setup, and no expense spared, good to see...
 
Will be interesting to see what you make, I have a few things the same as you and would be interested to see the difference in your result to what I get...
 
May make me change a few things too

Yesterday I spent the whole day at MRC doing more wiring for the crank and cam triggers and coil-on-plug setup, and setting up my Adaptronic ECU for direct fire (sequential) ignition. I was stoked when I cranked the car for the first time since the engine went back in, with different ECU settings for the new injectors, and it immediately started in a fraction of a second. It then proceeded to idle beautifully on 2225cc/min injectors :-D
Now I've just got to wait a week or two for the Johnson water pump to arrive, then MRC will be able to finish the last few things quite quickly.
