Papercup's V8 RX7
Discussion
As mentioned before, we are keeping one of the Rex oil coolers for safety's sake on track. What the hell, its there right? The fancy thing i bought a while back (picture on previous page) that allows remote mounting of oil devices without using a sandwich plate is in and its all connected and working:
You can see the sensor for the oil pressure there:
and below it Craig has plumbed the oil temp sender in the sump

kwithable. Just sent the V5 off to notify change of engine number and cubic capacity 
Spoke to Craig today; exhaust will be finished tomorrow, and the air-con guys also visit tomorrow to see whats needed to get it all working. The car now has an air-con pump from an early F-Body Camaro as the one that came with it from the Pontiac GTO has the pipes exiting on the wrong side.

Had to go to a wedding oop north this weekend, so a perfect excuse to drop in and see Rex. Lots more progress has been made. In fact, if the ECU guy hadn't gone AWOL this week the car would be running. Hopefully by the end of next week it will be.
You may remember I am being difficult by not only insisting on keeping my pop-up lights (meaning Craig can't use his normal route for the air intake, and he needs to use a different radiator) but also insisting on working air conditioning. Craig has risen to this challenge, and how!
The pictures above from a few weeks' back show that we originally kept the passenger-side oil cooler but the intake has now gone over there, meaning Craig has now decided to switch to using the drivers' side instead (the Rex came with both). So now the little power steering cooler we saw a few weeks back has a bigger brother behind it!
You can also see the aircon radiator, which is mounted outside the diamond-cut ally panel that Craig had made, and that can be seen a few posts up, looking very obvious. Thats now been sprayed black to suit the rest of the car. You can hardly see it any more, as its not only the same colour as everything around it, but also is covered up by the aircon rad. The aircon rad will have its own fans.
Where the original oil cooler was is now full of K&N!
You can also see the radiator, mounted vertically, the first time Craig has done this. Its inside that front panel and has its own fan.
Here it is with the bumper on, so show how well things are hidden:
With the aircon rad being black, its a nice 'stealth' look from the front, whereas I was used to having a bloody great silver intercooler in the middle!
You can see that none of this hangs below the bumper, so there shouldn't be any ground-clearance problems:
And from the side. You can see in the distance where Craig has used flexi tubing to bring the intake under the frame rails, and you can see the how well everything has fitted:
The engine bay with the bumper fitted. So that aircon rad is completely within the bumper.
I like the tidy way each coil pack is on the head, right above its own plug:
The underneath is all done now. Here is passenger side at the front, with the oil pickup and filter visible next to the sump, with the new downpipe from the manifold fitted:
From further back, showing the downpipes meeting at the centre box.
From the back of the car:
Here is the rear of the car with all the bracing fitted for the diff.
And from the side:
...and the diff brace itself:
Last but not least, a rather poor (sorry
) picture of the dashboard with those previously mentioned and pictured new Stack gauges in the original holes. They are the two clean ones, one above the other!
Getting very excited now

Won't the aircon rad block the airflow to the engine rad? I would imagine it'll struggle to keep the engine cool when you start adding power - or are you planning on drawing air from underneath the car venting through out of bonnet vent?
I doubt it. Air-con-rad-in-front is the normal way, and its normally aspirated, no turbo to raise underbonnet temps too high. Two small fans on the aircon rad and a big one on the main rad will keep things under control i would think....There is no bonnet vent; i've had to go back to the standard bonnet as the vents on mine hit the intake. I am very sad about this, I loved that bonnet
Mine is missing the normal undertray but we are trying to source one. Apparently it makes a big difference to the temps; they are much higher without it. Too much air comes in the front and simply escapes under the car.
