To fit the radiator, the lower front framerail brace tube was lowered about 3". The ABZ motor is very finicky on coolant system bleeding - this is what causes most overheating problems, not lack of radiator size. So, you have to run two B4 bleeder valve heater hoses (one must be spliced, the other simply cut at the right spot) and either an overflow nipple from the filler neck or OEM upper coolant hose with overflow nipple. Having a filler neck and cap on the radiator makes it too tall to fit without chopping up the upper brace and running a wider radiator makes coolant hoses difficult plus A/C and torque brace interfere with... everything. This is the best solution so far, but I could go to 26"x15.5" if I was willing to chop some stuff. Wimpy 16" Spal fan will soon be replaced with gonzo 2700cfm 14" zirgo fan with two stages.

Oh, so the radiator has a 90deg elbow welded on the SIDE of the tank and angled slightly using a modified OEM outlet hose to the thermostat neck. Tough to see in the pics.

So the ABS needs to go? I was suprised that the engine fits with it there at all. I deleted it on my V8 coupe

The ABS fits fine if the engine is low enough... maybe grind off the corner of the aluminum extrusion where it's closest to the valve cover. But I hate how mine is corroded and looks cluttered and its only ever made things worse in terms of bad weather braking in snow. It's probably good in wet weather, but... meh. Oh, also, I might move the P/S reservoir up to the ABS space to make more room for a turbo.

Yeah, I'm still working on that :P. So many crappy details to smooth out.

You could eliminate the PS pump and reservoir entirely with a remote electric pump. I used a late MR2 pump mounted down low. They can be mounted remote much further away too.

Also, you end up being able to eliminate the serpentine belt other than for the alternator. That frees up a lot of space for turbos or anything else.

See Eric's V8 CQ build thread. (I sold him the car earlier this year). There's actually more info on the PP thread: https://tinyurl.com/j5k4ure" onclick="window.open(this.href);return false;

..then you could put a vortec where the P/S pump is :))))) Still deciding if I want to get the A/C working, tho. I'm moving to Norcal where it's never too hot but there are times when A/C is like manna from heaven no matter where you are. If I get another newer car soon enough, I'll go with electric PS, ditch the A/C and serp belt and think more seriously about turbos. Or I , might sell this when it's a little more sorted, get another A8 and a Ducati 916.

where did you get the brace brackets? or did they come preinstalled in your car?

If I did it again, I would use an early v6 b5 A4 with 32v V8 or facelift V6 B5 with 40v V8. B4 is too hard.
