THE OFFICIAL X-FLOW SWAP POST!!!!!!

[X-FlowA2]

Well hey, I workat Circuit City roadshop in Newport News, come by tomorrow and hello at a playa, we can go to your crib and check your swap out, I wanna see it!

[2b rally golf]

i have to work tomorrow (mon) but tues if i have off i will stop by your work if your working. the motor is in and ready except for the upper radiator hose which will be in tommorow. in theory everything will work out and the car should start right up but i dont know about reality. we will just have to see what happens. i am not going to post pics until its running

[IwannaGTI]

finished pic ehhh i started in may 2002...ended 2 weeks later...easy swap...but now I am going to go turbo soon....i want more power... I am changing from my 4k to an a3 tranny, a3 cluster. I now need to source the a3 speed sensor, cluster and a3 trans....anyone want a 4k trans??

pics...only one i have of it in the car.....i will take better ones soon

anyone know what i need to change in order to get the a3 cluster to work??

[A2RicedGTI]

Can somebody take some pictures around the head? Im curious about what was done with all those emissions/airflow/vacume tubes. I know it should be stockish, but mine is going to be more frankensteinish...

[TBerk]

Anybody want to detail X-flow into A1 chassis troubles?

- Use of A1 mootor mounts?

- Use of Alt & P/S brakets?

- Use of K/S and ECU from non OBD-x?

- It's a 10:1 compression motor, right?

I have this saved in my notes for A1s. I'm always looking for good x-flow/A1 notes.

im in the prosess of looking for an engine and the 2L swap is looking to be the choice. but one question I have an 84 scirocco what would I do with the power steering pump....but I want to keep the nice belt

[155VERT83]

Anybody have recommendations for trannies (besides the original A3 unit) that match the ABA torque/hp curves? I currently have the stock ACN tranny mated to the tall block.

Good move on going with the A3 TRanny Specially since you going boost. I recently had got rid of my AUG for a CHE and what a difference. The longer gearing helps nicely and dosent top out at 105mph

besides the A3 Tranny i would go with a g60 tranny but that is more work involved. or stick with the ACN. If i am correct the ACN has a sweet 5th gear . I plan on putting in the ACN fifth on my CHE tranny sometime over the winter.

As for pics this is my setup pre-turbo

[roccostud]

would it be that bad to use a 4k tranny.....or is it a pain, i would love to be able to keep the 4k i like the gearing

[dubweizer]

here is my question full a3 conversion dash and all,obd2 with a/c the lower rad hose is gonna be pinched by the comp. what is the fix? is there another rad that will work.because the a/c is staying.really after i went through the trouble of putting the dash and the a3 heater box in the car

ha ha, clearance IS a problem isn't it? I moved the rad/ac condensor out about an inch on the pass. side and made a bracket for the bottom rad peg. I used a hydro front mount and two washers on top of it that I made to fit, along with a "thinner" M10 1.5 thread pitch nut...that gave me enough clearance for the bottom rad hose....I had to get the high pressure line from condensor to compressot lengthened as well...convert to 134a (I used a G60 compressor) and I have been cool ever since....

[A2RicedGTI]

When you do a crossflow swap, does it matter what coil you use? I didnt get the one off the donar car, so I just have my digifant coil and a MSD blaster 3 and 6a. Will either of these work?

ALso, I have a OBDII motor, but an OBDI wiring harness/ECU that I am going to use. MSD says you cant use their 6A ignition with a post 95 car (OBDII, basically) ANybody know why you cant use a 6A with a OBDII car? Because if its ECU/wiring related than I should be able to run it just fine...but if its something else...

[roccostud]

anyone know what would happen if i used a 4k tranny with a x- flow engine, if at all possible i would love to keep it

[PAGTI91]

4k tranny is fine, any 020 transmission is fine. 16v requires 16v clutch disc, 8v requires 8v clutch disc. IWANNAGTI has a 4k w/ .75 5th and a Peloquin kit..runs fine...tight gears....good for all motor...bad for boost...

[TheTrader]

Im runnin an AUG right now....

Its perfict for na with the 5th swaped to be longer.

[TommyC83]

wish i wasnt blind or i would have posted in here first but

can i use the digi1 setup on an aba swap into a rabbit, also the car its going into was carbed in addition to the digi1 setup, and the actual motor itself what else will i need to make this work i.e. aditional harnesses or parts of the fuel system. The reason i ask about the digi1 is because i am looking to turbo in the furture after i get the car up and running. and when getting digi! what all should i make sure i get?
Thanks

[vw mofo]

Excellent post BTW...

Here's mine...

After the paint job...

1990 Corrado with a 1999 ABA. Upside down throttle body, etc blah blah blah.

BTW: I'm using an A2 Power steering pump and bracket. It has AC but it doesn't work. For those interested you'll need a G60 compressor.

[dubweizer]

just want to say this is an awsome thread for all interested in this swap.i just finished mine,but i went the extra mile and did the dash swap and all the junk that goes along with that.i think maybe we should post some info on here for people who want to do that as well.i know there are probably easier ways to do it than i did,but my car is all a3 from headlight to tail light i used the heater box kneebar pedals and colum. and it all looks stock so if anybody would like info or if you have a better way let me know.i also have air and cruise.
98 od2 swap
BTW if doing this swap and using the dash and all the harness i do not reccommed using the stuff or a donor car that is a cabrio that is where mine was from and there is alot more crap to sort through due to the top and all that.just my 2 cents

[vdubspeed]

vw mofo-

I'm not hating at all but why did you swap in an X-flow into your corrado. You already had EFI and could have used your digi1 for a turbo or something.

In any case, it's the FIRST Corrado I've seen with an ABA. Congrats...

Jason

[vw mofo]

Long story...

- Bought the car in January 01.
- Charger went in February 01.
- Was about to order a turbo kit, got comp test and leak down. Two cylinders were making less than 1/2 of the comp they should have.
- $2000+ for a rebuild, still no boost 85HP woo.
- $3500+ for a vr swap
- $1200 installed for an xflow.

You do the math...

At any rate, I just bought another Corrado to replace this one. I don't have the time or money to make it fast. So hopefully whoever buys it will continue with my plans.

You're probably going to start to see alot more Corrado's showing up with atleast xflow heads on them as the original 1.8's start to get tired. I know of at least three others and one that has the complete engine like mine.

[msnafu]

excellent looking swapa nd great looking car! Could you take a detailed picture of that inverted TB and explain how you ran the throddle cable? A lot of people say that they have inverted theirs but never give any hints or tips that might make it easier. Also did you just put a K&N air filter at the end of your intake? If so, whats the part number? Ive asked many times and nobody seams to know. Thanks...

[X-FlowA2]

Hey VW Mofo, I have the same exact plate! good choice. About the TB, I dint flip a thing I just put it in. The only thing that hit was the little bladder that controls the throttle after let off. I didnt know till way later when I saw a very small indention in the reinforcment for the hood. So what! Now if your runnin OBD2 that might be an issue, I have yet to see one done in person.

[vw mofo]

My car is a full ABA swap. Motronic OBD2, etc...

Here's a pic of the TB. Hope it helps.

My hood wouldn't close with it right side up. G60 hoods sit VERY low. The car has a VR6 hood on it now, but I'm too lazy to turn the TB back right side up.

Oh and the filter is a p-flow knockoff from Denon I think. I didn't do the swap, but knowing what I know now, I absolutely would try it!

[dubweizer]

i don't have any pics of this yet but i took the t/cable and cut some of the cover off of it at the fire wall to give me more exposed cable and then ran it between the intake and the valve cover and it is very clean and works great.just another option

[msnafu]

Thanks for taking the pic vw mofo. Ive even had people tell me to use the passat X-flow head because the cable runs on top of the intake manifold but that looks like easy modifications and is a lot cheaper. Im also going to look at dubwisers suggestion at running the cable between the head and the valve cover. This is the last mod I have to do before the wireing

[blubayou]

here's mine again, just cause my other post got messed up by moving pics:

It is in here:

These pics are old, so some things are different now.
-I have eliminated the AC altogether (had just the compressor before, to run the belt on it).
-There is now a 19 row mocal oil cooler where the AC condensor used to be.
-The battery is now a red top, relocated behind the passenger seat.
-The intake piping only goes to the original battery location (less heatsoak with a shorter pipe), where I now have a stock A3 airbox with a drop in, rather than the open filter.

It is now taking a long winter nap, so hopefully more will be on the way

[msnafu]

looks like a lot of fun. Any numbers, like HP, Tq, 0-60, and 1/4 mile?

[blubayou]

Nah, I don't drag, and haven't had a chance to dyno yet. I did run it at Lime Rock a few weeks ago and faired pretty well. I wasn't supposed to time cause it was a driver's school, but I had my camera mounted in the car, so I got some rough estimates of time by the ticker on the camera

[blubayou]

I'll get to the dyno this spring, I hope

[JNZZL]

what is the x-flow. can someone please tell me

[vdubspeed]

X-flow is the name given to the engines where the intake air comes in on one side of the head and leaves on the other. The term x-flow or crossflow is most commonly used when referring to new model 2.0 code ABA engines but back in the 70s VW ran x-flow heads on their small displacement motors. However the intake/exhaust went in and came out opposite of todays X-flow heads/motors.

[banacaspyder]

anyone have any info to do this swap in mk1? im pretty much done with mine.. im at college now so i havent had a chance to work on it for a few months, ive still got wiring left i have to move the fuel lines towthe other side, timing, all the radiator hoses and all that good stuff left... ive got this link http://www.psycode.com/aba which has been a GReat help, but havent been able to find anything else.
thanks for help.. its in an 88 cabriolet. mk1 chassis

[GTI_Andy]

I'm doing an OBD2 swap in my rabbit as well. I'm using all the wires off the donor car from engine compartment wires to fuse box and interior wires...

I haven't had time to figure it out cause it's winter now and the car is in storage so I can't play with it anymore till spring.

Left over plugs for 1997-1998 2.0L 8v

Turn Signal Harness

Yellow Plug: Yellow/Light Blue = ?
Black Plug: Black/Blue, Blue, Red/Yellow, Black = ?

Fuse Box

Harness E Green Colour: Red/Yellow, Red/Black = ?

Instrument Cluster

Brown Plug: Brown/Green to Big yellow Plug = Air Bag ?
White Plug: Brown/Red = ?
Blue Plug: Red wire = ?
Radio Harness

Brown Plug: Brown wire = ?
Brown Plug: Brown/White, Grey/Green = ?
Black Plug: Red/White = ?
Black Plug: Black wire = ?

VAG Harness

Light Grey Plug: Yellow, Grey/White = ?

Engine Harness

Blue Plug: Blue/White = ?
Yellow Plug: Black/grey = ?
Green Plug: Red, Red/White = ?

I was told that a few of the wires needed to be spliced together but i couldn't understand why unless a module or soemthing was missing...
