Help me solve a riddle

[Error404]

OK, so a few months back I bought an ABY cross member and intercooler off another forum member. I stuffed it away in a box and thought nothing more about it.

By chance it was out of the box with some other parts when Pete (Acidburn) popped round. He commented that it didn't look like an ABY intercooler and might be an RS2 one.

Great I thought, maybe I've got a bargain there - so I looked into it.

First of all I check the part number on it which corresponds to an ABY part number: 8A0 145 805 B.



But then I looked at some pictures of ABY coolers and sure enough mine looks different - its longer and has less rows - 10 vs 15 that appear on an ABY cooler.



I measured the core which seems to be larger than an ABY cooler too
500 x 180 x 64mm
Interestingly it seems to be more like a bar & plate construction than a tube & fin







The cross member looks more like an RS2 one with the bracket off to one side:



Compared to an ABY cooler and RS2 cooler it doesn't look like either

Its longer than an ABY


But the end tank is not the same as an RS2


The cross member has been damaged and repaired at some point which made me wonder if the intercooler had been damaged had the core replaced maybe? But the welds look factory to me.

Can anyone help me solve this?

ABY endtanks with custom core id guess (RS2 has 3bar endtank data)

bet it works well!

[Acidburn]

as sean has said I think its had some work done, be interesting if anyone else can shed some light onto it. It did not look stock aby when I saw it.

Any links to the f/s thread?

I got both bits off Steve (RS2315). They were on his RS2 and he discovered there was not oil cooler duct fitted - when he went to fit one he found it wouldn't go on as the cooler was too long. So he checked the part number on it and assumed it was an ABY one (as per the part number on the end tank). So he fitted an RS2 cooler and cross member and I bought them off him

[Acidburn]

Cheap bigger ic for you then. I know when I saw fitzys avant, his rs2 ic is huge behind a s2 bumper

The ends look like ABY but that looks like it has been re-cored. Have a look at my old one on http://www.s2forum.com/forum/showthread.php?t=57990 and it is err......still for sale

It sure seems like a good upgrade over a standard ABY one and looks to be equivalent to RS2 so I'm pleased with it.
I'm going to cut the mounting off the cross member and weld it to a nice 3B cross member I have, then I'll get it painted up
