I'm in the middle of swapping engines in my 92 Metro. I do not have then G13b yet so i'm trying to do some prep work first. As of right now i already have a 92 G13b engine harness, along with the front body harness. I have the G10 out of the car also, and am about to pull the tranny. I also have the dash out of the Metro(wish it were an mk2 due to this).

I have a few questions about the swap that i haven't found answers for:

1. From what i've read i understand that you cannot use the 3 cylinder axles as they are not spaced apart correctly, or the hubs, got that. However, i've read conflicting info on whether or not you can use G13 SOHC axles and hubs in place of the G13b axles and hubs. Are the splines the same and will the SOHC axles/hubs work in the G10 tranny.

2. If you can use the SOHC axles/hubs do they have to be from an mk2/3? I have TONS of mk4 stuff around here and i could get a set of the SOHC 5speed axles/hubs without any problem. I need to know if the MK4 stuff will work.

3. Will the MK4 motor mounts work with the G13b?

4. I have a few questions about the wiring differances between what's in the car and what i have for the car, but i'll ask those questions when i have pics of everything. I should have the pics by tomorrow night.

Thanks and any help would be appreciated.

Kyle

i had about a year off work to play with cars and did 5 twincam swaps into verts during that summer. i also had unlimited time to prowl the junk yards and make comparisons of parts.

the hubs on a standard metro and the vert (which are also very similar to the mk4/5 hubs) will accept the outboard splines on all the 3 banger axles as well as the mk4/5 4 banger axles.

when i first swapped the twincam into my mk3 vert, i used mk4 sohc 1.3 axles with the existing vert hubs and brakes. i also used the intermediate shaft from the mk4 sohc 1.3 and the motor mounts from the same donor car. there's no difference between the gt motor mounts and the sohc 1.3 parts nor is there any difference between the intermediate shaft (as long as the donor car is a 5 speed manual tranny, the automatics' jack shafts are longer.)

the outboard axle splines for the sohc and 3 bangers are longer than the ones on the gt axles (which are noticeably shorter, maybe a third of the length.)

i had a member tell me that the non-gt wheel bearings weren't up to the task of taming the torque of the twincam and would fail prematurely. i had no problems during the season that i ran the vert hubs and brakes.

it's when you swap the gt brakes and associated knuckles and hubs that you run into axle compatibility troubles. when you make that jump, the gt axles become a "must have" component.

one other thing that you will find is that the rear mount for the 1.3L cars bridges the tranny and block. that means that you have to have the mount that bolts to the engine to line up with other half of the mount that bolts to the chassis. then, the place where the shifter mechanism bolts up is different from the 3 banger and is, overall, shorter in length. grab the shifter from the sohc donor as well or you'll have to cut and weld the shifter assembly to make it shorter.

if you come up with any other questions, post them here and i'll try to keep up with your swap.

you can use any non gt 4 cylinder axles with your 3 cylinder hubs but I think you'll want to swap to bigger brakes eventually. You might as well get your hands on GT knuckles and axles, or get sohc axles and later swap for sohc/vert knuckles.

if you are considering the gt front conversion, I have everything you need, from never used brembo rotors and quality pads, to stainless steel brake lines. complete with quiet wheel bearings.
however, shipping might be a bitch

id let it go relatively cheap, im considering importing a cultus instead. maybe sell my car.... so I dunno, just throwing this out there good luck on the build.

did you happen to get a gt transmission with that motor? or do you have one right now?

As you can see i almost have everything out. Here is where another question comes up.

I bought a few harnesses from a fellow member on this board. They are from an mk3 GTi. The harnesses are still on their original crossbars. I know that the bar with the O in the middle, replaces the one that is attached to my dash, i however do not have a clue where the other bar would go, as i cannot find that bar in my car at all. Here are some pics, any help would be appreciated.

This is the one i'm confused about...

Not completely sure but i do see it has the AC/Heater controls so might want to start looking there on the chassis.

They are not actually attached to the bar, just chilling with the wiring. Already looked in the car.

We think that the extra bar might be the crossbar from an MK2.

We have the wiring swapped out. So now all i need are motor mounts, an engine, axles, and other misc stuff.

Is that in a mini storage? If so, thats an awesome idea. When you get this thing in the final stages, I wan't to drive down and look at it. You're not very far away from Birmingham.

you must be so busy building that car that you don't have time to keep us updated. :lol:

shoot some new pics so we can see what progress you've made.

I don't have any new pics but here are some updates.

I've swapped over the dash harness, and the engine harness. I've decided that i would rather buy a front chassis harness (ECU, headlights, etc) than try and splice the existing harness. I have the engine for the car. Just last night i rolled it out of the shop and completely cleaned out the engine bay, got all of the oil and road grime buildup off of the car. I also removed the charcoal cannister and other useless vacuum lines. I have a vacuum manifold to mount on the firewall also to help clean up the other lines.

Plans for this week:

1. Swap the GTI front hubs into the car
2. Find an mk3 GTI front chassis harness
3. If my Toms II chip ever arrives i'll put the dash back together.

When i do eventually get a front harness i'll try and wire tuck it to clean up the bay a little bit.

The engine that is going in the car has the following mods:

mk3 G13b (duh!)
Firefly cams
Underdrive pulley
adjustable cam gears
ported TB and intake
and around 30K miles on it.

I'll try and get pics either later today or tomorrow.

Kyle

Where did you get info on the vacuum manifold and canister removal? Any links?

Here is a link to where i got the vacuum manifold.

http://www.go-autoworks-store.com/govamalogb.html

This is the same guy i had do my charge piping and intercooler. He is in Montgomery. I decided that i didn't need the charcoal canister and just unhooked it from the lines on the firewall. That removed quite a few lines by itself.

I went and took some pics today after class. Here they are. Notice the lack of rust on the car. :mrgreen:

You weren't lying when you told me that engine bay was clean. The thing looks like a brand new car. I also like the blue valve cover, will give it a kind of two toned blue thing going on.

Yeah, i owe Robert big time for that. I'll take some pics of what we did last night.

Not planning on putting the slicks on the car.

Ok, a little update. We've run into a few more problems but here are some pics from last night. Notice that we used spray in bedliner on the front support section. It turned out really well we think.

We started on a minor wire-tuck last night. We are not going to do anything with the driver's side until we figure out the wiring issues.

very good job so far its always fun to tear stuff apart i have 2 gts and i have swapped motors in them its quite the shoe horn to get them in and out in my experience its good to marry the transmission and motor then stuff them in how goes the wiring? looks like fun i am going to do a gt conversion to my vert fly cheers..

A little update. I decided to buy a GTI front chassis harness. We've already changed out the old harness with this one. So now all the wiring in the front of the car is from a GTI. I found a passenger side mount that works. I still need the rear mount bracket. We are having a HELL of a time getting the steering rod thing(that mounts to the hub-can't think of name) off of the hubs. We've used a ball-joint separator and no luck there. We've run out of ideas on how to get them out, 1 on each side.

I still need discs, a MAF sensor and housing(working on the housing), exhaust manifold(working on that too), new clutch, throttle cable, and a few other little misc things.

I'm begining to doubt that this will be done this year, maybe in January. I just need some cash to buy the stuff i need.

*See link in signature for deal on turbo kit*

lol,

Kyle
