Mk 1 Engine Upgrade

[type3kid]

hi all,

i've heard a whisper that a Mk 3 engine would easily fit into a Mk 1.

is this true? especially the easy bit...

also, is this legal?

cheers

I'm guessing you mean a mk2 2l engine?

Only issue you should have is with wiring, ecu and fueling.

If you want to run the standard mk3 ecu you would have to swap out the fusebox and all the looms. Also if it is a carbied mk1 you will need to run new lines and most likely a new tank.

It will go in on the mk1 mounts though so no fab work is needed but you would need to get it engineered I would think.

Wait for Golf Loon to respond he is up to speed on this stuff and can help you out.

a mk3 1.8 and 2L would fit. Engine mounts from the mk1 will bolt onto the mk3 block and gearbox.

with regards to engineering in nsw...

You can go the "100% correct" way, and get it engineered, in which case, the engine should be from a donor car complianced in australia, and you should keep all the original ECU, fuel, intake, oil breather, and emission control equipment from the mk3 model you took the engine from.

Because of the power upgrade, most engineers like to see a brake upgrade done aswell.

You will also need to reweigh the car at a weighbridge and give the engineer the reciept.

OR......

you can do the dodgy way (which is strictly speaking not legal) and get it working, then try and squeeze a change-of-engine-number form past a not-too-observant mechanic when it's done, or at the next rego.

the problem with this way is that your insurance company won't like you and your car can be deemed unroadworthy and you can be at fault in the case of an accident, all assuming that the insurance person can tell its not the original engine (which is reasonably difficult).

this way is heaps easier and cheaper, but comes with those risks.

PS: If you are a policeman or rta person and reading this, i might add that I do not endorse this method at all and i have just heard of other people doing it.

yes, they physically fit. it's just a matter of which fueling you use as to how easy the conversion is.

In VIC, you can swap upto 300cc larger engine, without need for engineers cert. I presume it's different in NSW, as you guys have sucky laws.

1.8 would be alright, I went with a Heron motor (original 1.6 GTI engine) which I am going to run on duel carbs eventually.

Mk 3 motor

It depends on the amount of time you have and $$s of course. The simplest is a 1.8 and put a good webber on it. They go pretty hard and you could do it in a weekend whereas the EFI route can take months. Rego wise, unless its a blue slip, noone will know as they look identical to the untrained eye.

[type3kid]

would prefer full EFI and air con if it could work.

so where can you get a front cut or all the bits to do it?

[static1800]

If you are fully serious about it speak with Golf Loon(matt) from Camden GTI, he will most likely have all the parts and will be able to help you out.

Also post up some pics of this mk1 of yours

Webbers are great but try and find someone to tune them! having a hard time to find some one in melbourne who wants to go near them.

[tassie_euro_mk1]

a good conversion for the mk1 is also a 2E 2L enigne from a mk3 (115 hp ?)or seat. Use the donors car ecu, fuel pump, injection and wiring and it makes for a fun little car. Mate has one in his mk1 and its a blast

Yeah Aaron post some pics

1.8 and a progressive weber is the way to go. Bolts straight in and goes harder than with the injection. Easier swap than the 2.0 and much more responsive. I have two Mk1s, on with a 2.0 and one with a 1.8. For a daily I'd recommend the 1.8. every time.

Hillway Dyno Tech in Kilsyth can sort your carbs out. They tune racing Alfa's all the time.

Nigel over at The Carby Shop in Knox can re-manufacture them too.

300cc over the original engine or 300cc over the maximum engine available for that model??

[Jarred]

i believe it was for the chassis, although the GTI (hence 1. never officially came out here.. so yea. I'm not 100% sure.
