90CQ Turbo swap project

[etsola]

Hi there, first and quick post - more to come.

Quick question :

I will eventally drop an AAN engine in it - I know the intake creates a problem and will need to be customized to fit the Coupe's small chassis (also the radiator is the way

Will a 3B intake manifold fit (fit on the AAN)

Will it have the same inlets on it (vacuum, etc...)

Will it be easier for my setup ?

Basically : 3B intake or AAN modified on the AAN head (engine) ?

Thanks

P.S. I'll have a lot like those to come. I'm slowly sourcing the parts and putting this together.

P.S. #2 Anyone knowledgable on 7A engines in the Ottawa, Canada region ? My 1990 (1st gen) CQ doesn't run currently

90 cq,what typ of chassis? b2-b3-b4? or buildyear?

[etsola]

Sorry - 1990 pre-March - B3

[quattro-nick]

3b or aby or adu intake will fit.vacuum lines need to be adapted,also isv lines,it's not a straight fit.
i have modified my AAN intake in a b2 chassis with the radiator on the origional place

What do you think is easier ? Modifying the AAN ingtake to fit or modifying (adjusting) the 3B (ABY or ADU) intake ?
What about piping routing for the intercooler afterwards ? Easier with AAN or 3B intake ?

Thanks for those wuick replies ! !

if you fit a reverse (3b-aby-adu) intake manifold you can place origional turbo hoses and intertcooler from a 3b in a b3 chassis ,it means that everything is a direct swap.
with a modified AAN intake you need a custom intercooler and pipework
i think it all depends what you want with the car and how handy you are in making things
will you run with a standaard AAN engine or more horsepower?

For now, stock AAN.
It's just for me, sourcing AAN parts is a lot easier (were found in S4-S6's)

3B's were only found in Audi 200 Turbo Quattro 1991 (1000 of them sold in the US).

I can make-fabricate things - But that is mainly the question - Will I need to make less fabrication with a 3B intake (I guess piping is not so hard to come about) ? Or less with a modified AAN intake ?

The question is also, I already have my AAN intake and all - but I could source a 3B intake on this forum for around a couple hundreds $$

Also, using a 3b - no need to delete the ABS module and tilt the rad right ? Or this can also be avoided with the modified AAN ?

Thanks again

you have also 3b in the first s2
here some pictures of my car
probably you need to make also a custom servopump bracket

Nice bay !! Was it difficult to fabricate/modify the intake ? My brother bas access to an aluminium welder.

I know the 1st S2's had the 3b's. That's why I'm inclined to think it'd ne easier to fit

[poor-boy]

An ABY is easier and the radiator fits back in it's original place, try and source ABY bits for the AAN.

Could lend an ear and meet a fellow enthusiast from the region.
