Cost of 20vt/1.8t vs abf on bike carbs

Just wondering what the cost difference is likely to be when choosing an engine conversion for my 1983 golf gti. Obviously know the abf is cheaper but by how much?

The most information you could provide on both of these would be great as I'm still very undesided which one to go with. 

Thanks in advance

Tbh, the cost factor is down to how you want it, you can do an abf swap really cheap using 8v box, and diy manifold etc but if you want neat and better stuff then you gotta spend a bit. 

Been watching 20v's lately and they're creeping down in price as the block/turbo etc. 

But I think a 16v is more fitting to the car of that's what you like, if not I'd be tempted for a tfsi now over a 20v

im about 2k into my 20v and probably about another £5-600 till i would say its useable. ok this price does include a few performance accesories and brake up grades like a upgraded intake pipe, forge oo8 diverter valver, 9 inch servo with 22mm master cylinder, hydraulic pedal box.
it could be done cheaper but i wanted a good spec build

I'm about 3k into my 20v conversion so far and got more to spend yet. Mind you, I have bought 2 engines as one was knackered and the one I have now, has had a £1000 spent on it at the machine shop, rebore, new pistons, bearings etc etc. I also upgraded the turbo to k04-023 and I am fitting a Wavetrac LSD so there's another £1000

I'll be pushing on to 5K just on the engine lol

I'm about 4k into my 16v G60  conversion.
Engine was cheap but it's everything else that goes with it..rebore for bigger KR pistons polished and ported head custom inlet manifold
CTN gearbox plus a Limited slip diff

G60 Supercharger plus rebuild
16v manifold and bigger exhaust 
G60 Loom and chipped ECU 
None of these parts are cheap..
But in my opinion its period for the mk1.
Don't get me wrong 20v turbos and 1.8t etc are nice but not for me. 

GeeBee, you just reminded me! I forgot about the exhaust and manifold I bought, there's another £1000 lol. I didn't realise how much I had spent until I read this post

Not even adding mine up. Minus £1000 for no LSD thouhh

As already said it all the extra parts that makes the 20vt more expensive than a  non turbo engine conversion, such as turbo manifold, intercooler, radiator, engine mapping, suitable gearbox, more expensive clutch etc.

You should be able to use a lot more existing parts for the abf and it's easier to setup.  And on bike carbs sounds   

Thanks for the reply guys. Still no further with what I'm going to go for.

Some days I really want the abf for the cost, cleaner bay and just the fact it will be easier to install etc and other days I just want the power of the 20v

A worked ABF will outperform a stock 20VT any day of the week, my single throttle worked ABF made 20whp more than my son in law's 9N3 Polo Gti with Revo stage 1 (at 1680m altitude). At sea level the difference will be even bigger.

Do twin 45's over carbs. I've had both (still got twins) and much prefer them

Do electronic fuel injection over any form of carb using a modern ECU !

On a 16VG60 Digifant can be tweaked but it is always a compromise, believe me I have been there !! Even Jabba could of never get it quite right.

Also consider whether fuel consumption needs to come into your decision - carbed especially twin setups are very thirsty, whereas the same engine on EFI will give you as much a 10mpg more, not to mention the better power delivery.

After a little thought i went for the ABF in the end just because it will be easier for now and can always change to the 20vt in the future.

I bought a mk3 gti 16v last night for a grand total of £200 - BARGAIN!

Even if it does have an oil leak…

Hopefully pull the engine out this weekend and see whats causing it.

Thanks for your responses. Much appreciated.

I have the abf with zx9 carbs in mine,keep getting tempted to change but I love the look and sound toooooo much
