Unfortunately progress has been slow on the red beast due to having started a new job. Though I will hopefully have some photos of where Im at posted up in the coming weeks. 

As for the yellow one.......
Well another hurdle has presented itself. My PWR radiator has shat itself  
This is the second aluminium radiator that has shat itself now...though originally I thought the first one was due to it being a cheapy but now the expensive one has done it as well. Not sure if Im just unlucky or that there is something seriously wrong with my car.
 
Time will tell I guess.  

Just had one of those silly thought bubbles.  With 18 psi boost, are you possibly over pressurising your aluminium radiator. Maybe a head gasket issue.

If it is electrolysis, there are instructions with pwr radiators that give you a test procedure and a maximum value (unfortunantley too late in this case.)

Are all your rubber mounting grommet s etc in good condition? They arent vibrating themselves to death?

A decent amount of progress has happened over the last couple of weeks. 

I changed out the timing belt for another new one as I wasnt happy with it. 

 
Fitted the refurbished radiator and fuel tank.


The inside of the refurbished tank


A Walbro 255 fitted

 
The tank back in the car


All cooling pipes flushed and new hoses fitted

 
Swapped out the Gen 2 igniter and coil for the Gen 3 units so the coil to distributor HT cable would fit. 

 
Engine on its way to its new home.

 
Reusing the 2 1/4" cat back from when the yellow one was NA.


 
The car is currently ready for the wiring to begin which does seem like it will take a little while. Reason for this is that its not only the ECU connectors and the EA-1 connector that will need re-pinning. The EA-1 will need to be cut and have a Gen 3 connector put on to match and the other EA connectors in the engine bay fuse box will need almost an entire re-pin. 

Taking a break from the red car. I have tested for electrolysis in the PWR radiator. 
Fortunately or even unfortunately the result came back with no stray currents whatsoever. 
Even tested at microamps with still not a stray current present. 


 
Anyway I swapped out the PWR unit for a stock Gen 3 radiator and have now decided to run 50/50 mixed coolant to combat heat just in case that was the cause due to sitting in bumper to bumper traffic regularly. 

Stock radiator just about back in place

 
So currently the yellow deuce is in the midst of having the cooling system bled. But is not quite perfect yet as it has a high and unstable idle which is quite unpleasant for myself and other drivers on the road  But will hopefully have it sorted out this coming weekend so that its ready for the next club run.

Hey Deco
 
Be careful with your coolant dosing as sometimes with some coolants overdosing can be as bad as not running any coolant. 
Some effects of coolant overdosing are:
Chemical deposits, precipitates and gels that reduce heat transfer, can cause water pump seal damage or failure and system plugging of coolant passages and radiators.
overdosing can also cause high nitrite, high conductivity and possible high PH.
 
I highly recommend following the coolant manufacturers guidelines when it comes to dosage as I have seen quite a lot of problems caused by overdosing cooling systems.

It's not a recommendation of coolant mix in relation to the engine you need to go off the recommend coolant mixture provided by the coolant manufacturer as each coolant manufacturer will have different recommendations for their coolant.
We not only do oil analysis at work but coolant analysis as well and it's a commen problem seeing people overdose their coolant systems thinking it will help improve the ability of the coolant but it actually does the opposite.

Ah ok well if it's premix than that's ok.
