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

[PAGTI91]

replace your temp sensor and the O2 smokin man..they are VERY important sensors...and relatively cheap...

unplug the coolant temp sensor, see if anything changes, if not, its probably bad. I would replace it and the O2 if you can scrape together a little (under $100) cash...

The best is to use VAG-COM. Get the CEL's and work through it...otherwise its guesswork...

So I've recently been looking into the x-flow swap. I have a 90 8v that I want to add some power to, but I need to keep the reliablity that I have now. I'm also a soon-to-be college student so money is an issue. I think that the x-flow swap is my best bet? What do you guys think? Also have a question its probably gonna sound dumb but what cars had the obd1 engine and what had the obd 2 and what are the major differences. Also what would I expect to pay for this swap if I did it with my father? And if you got a chance check out my project so far and tell me if you think my car is worthy of a new engine. http://www.printroom.com/ViewAlbum.asp?userid=BigJohnson50&album_id=115947

Im sure its in this post somewhere, but OBDI was from 1993-1995.5 (if you get a "95" engine your arent 100% for sure going to have OBDI) OBDI was from 1996-1999.

Whats the difference? OBDII has more diagnostic systems and a more anal computer. If you do significant mods to a OBDII car (cams, possibly intake/exhaust, turbo, etc) you will have to reburn the ECU. There are extra sensors that you have to hook up (all I know of is the extra O2 sensor)

OBDI had some oil squirters in the block which also makes it more desireable.

Can anybody answer my questions posted above?

[PAGTI91]

His name is Robert Bentley...

Seriously, the A3 Bentley has diagrams that will allow you to trace any wire in the harnesses. The reason most of us don't get into specific wiring talk is that unless you take notes when you do it, you gotta go back into the Bentley and start reading diagrams, which is not much fun unless your doing it for YOUR car...not somebody elses...and discussing wiring gets VEERY wordy...

I'll look em all up and label them for $5

Maybe we should start a thread on reading the Bentley Wiring diagrams...they are INVALUABLE when swapping...

BTW...I would not use the A3 interior harness in a rabbit, its got too much extra junk and the dash switches etc are different....use an A2 harness...see silvervdubs post about converting a rabbit to CE2...good luck!

[deathhare]

Has anyone called 1800vwparts to find out a complete pricing on a kit w/motor for a rabbit?

[BigJohnson]

Anyone who did the project. How long did it take you to pull your engine out and get the new one in and running?

[X-FlowA2]

I started my swap on spring break it took roughly 2 weeks to do, The electrical stuff will kick your ass, (thats why I made the post). It was a while until I could get all of the bugs worked out. Have you started yet? Im going to post some pics in a few days. Pics are so cool!

Just for your information I looked all the wires up already that's why I made the above post of those plugs that areleft over or unclear from the swap. Also from what I was told a few of those wires need to be spliced together which I did not mention cause someone told me already but I wanted to double check it here incased i misled someone that is taking it down for their swap.

I saw silverveedubs post but it doesn't answer my above questions.

with a multimeter and a Bentley, almost nothing is unclear or left over....

have fun sorting it out..you'll be happy when your done

HELP!!!!

I'm right in the middle of this swap and can't figure out how to use the A3 acc. with out using A/C... Is there a special bracket for the alternator?? somebody help me please. I really wanna finish this before christmas

[deathhare]

I think you use the vr6 non-a/c water pump pulley and thats it. Call up Tomas Tuning in the bay area and ask. I know they do this alot.

ha ha...you'll be seeing lots..with turbos...you won't think its a step back when your looking at tail lights...

[quickyg60]

i ll beleive it when i see it

[quickyg60]

working on a VR no 2.slow will ever beat

[IwannaGTI]

do you want to make a wager? my xflow is getting a wee bit of boost soon

[BlauSlc92]

Either clutch will work with this swap? Which kit should I buy? I see that the older sachs 8v kit does NOT come with throw out bearing, so should I use a 2.0l one? Thanks guys
Derrick

[nickcook_01]

Hey guys I am doing a full 2.0 crossflow swap into a rabbit, I want to know what radiator, rad. fan, and rad. hose combination worked best for everyone that did this swap.

Thanks,
Nick

[GTI_Andy]

I'm using the 16v rocco long rad and as for the hose I'm using the upper crossflow hose. As for the bottom hose I'm not sure yet cause my car is still a project.

[A2RicedGTI]

Are you just supposed to use A3 radiator hoses, or can I get away with generic radiator hose and bend it around to where it needs to be? In an A2

YES.

[A2RicedGTI]

Im trying to avoid buying this new, if possible. And with the junkyards aroud here that means shipping it from somewhere, and I dont even know exactly what I need.

$58 new. Upper radiator hose.

[BlauSlc92]

Ack.. another question from me. If I use a manifold from the Aba, will a regular dual downpipe fit ok? In first post you said you had no problem, but on TT's site it says

quote:

---

"If you are installing the engine in an A2 chassis (‘85-’92) get the ABA exhaust manifold and downpipe. You need the A3 downpipe or a TT downpipe in order to accomodate the taller block"

---

so does this mean any new manifold along with any dual downpipe will work? Or MUST I use an A3 downpipe or TT downpipe? Kinda confusing.

OK.. I've taken some time away from my car... It's been sitting in hiatus waiting for me to remotivate myself. I'm back. I am still tackling the rev limiter. I've tried a buncha different things.. HOW DO YOU DO AWAY with the rev limiter? Over 5k, it shuts down for a few seconds... Again.. 86 GTi. obd1 xflow with giac chip, 272 cam other stuff... thanks guys...
Brian

[IwannaGTI]

a3 cluster i have been told with a speed sensor...got sensor and cluster for under 100

[blackgold]

there has to be a way with the A2 cluster. I'm told there is. thanks..
Brian

[X-FlowA2]

Yes, you need to use the cruise control/MFA from a late model jetta/golf. the 3 pin version. Thats what ive heard but I have yet to do it.

[secretproject3]

im going to be doing a crossflow in my 87 gli.. i plan on doing the a3 dash swap.. would using the a3 fusebox be easier than just getting the ce2 fusebox.. im kinda in the dark here and would prefer to know what im doing before i start(things go a bit smoother that way).. any info is greatly appreciated..thanks

[blackgold]

A3 fuse block is CE2...
Brian

[secretproject3]

ahh thanks

[dubweizer]

Thought i would bring this back from the dead.i hope somebody can help me out here 91 gti 98 obd2 a2 subframe it is all in and running but not that i changed the rear mount from braken to new the motor is sitting higher on the pass side and it is hitting the frame rail on hard acc.i am using the stock mounts from my a2.it worked fine with a bad rear mount so i know there is something as far as this mount goes i need to change and btw it is the p.s. pulley hitting

[blubayou]

I used the A3 subframe and the VR6 rear mount, fits a lt better, and let me use a stiffer mount (VR6) to take up some movement
