thats a lot of work for ten bhp. you would be far better off fitting bike carbs to your one litre or fitting the throttlebody, head and inlet manifold from a late spec mk3 polo

is it alot of troble fitting a 1.3 engine with a mk2 carb and inlet bearing in mind i work for a garage?

considering you will have to change the fuel pumps etc, yes it is a hard way to do things. if you gonna go for engine swaps you might as well put something decent in

eh up one sec it isnt hard if you use a golf 1.4 throttle body
its throtle body on mk3s not carbs

use the 1.4 throttle body and the inlet manifold from a mk3 golf
thats what bi ve been told to do and that what people have done in not time at all

going by the title i think he knows its single point injection! but your right, in fact a whole late spec polo 1.3 head, inlet and t/b (the late spec 1.3 t/b is bigger than the old ones, in fact its the same as the golf one, only it need no modding to fit) will fit on with ease and give really good gains esp with a gt cam fitted. have a look over on polo3.co.uk cos there is a whole load of posts on tuning the mighty 1 litre.

yea i know what im talking about, i was going to put a 1.3 inlet on it with a mk1 1.8 8v golf carb, changing the fuel pump is nothing thats easy to me.

im currently helping my mate with a corrado make it 4wd with tt rear limited slip diff and a 1.8 20v turbo engine and we have had to make engine mounts diff mounts etc.

might be worth investing in a mk2 polo for bits? still think bike carbs would be a better option though than the golf carb (i take it that its a pooburg and not the weber direct replacement)
there was a guy on clubpolo who ran a mk4polo 1600 small block on bike carbs in a mk2 polo shell, it sounded the dogs! went well too according to the owner

thanks for the fast reply well i got a 1.8 8v at work from a mk1 golf becasue we are doing a conversion to put 1.8 20v turbo into it. i want to make a quick 1.0l becasue i think it will be good to be race someone and say its only a 1l

Any ideas wher i can get a gt engine from?

tuning the 1 litre not go to plan? clubpolo or polo3.co.uk is probably the best bet for finding a gt engine

dont know what to do, might leave it as a 1l and do some basic mods to it then buy another polo mk2/mk3 and make it rwd with a fireblade engine or such like as i dont know of anyone who has done it to a mk2/mk3 coupe alll of them seem to be mk4's

I reckon you should put the 1.6 from the mk4 Polo/mk3 Golf in. They care quite tunable. The aforementioned guy on clubpolo's is meant to be a monster i remember talking to him and he said his only problem is he keeps blowing gearboxes as with the bike carbs its got far too much torque lol.

the aav is practically the same bar the bottom end (if its the 1.3 spi that i think it is!), so thats the only bit you would need to change, although saying that the ecu runs a different map and the head/inlet manifold might are larger on the 1.3. the loom stays the same

for the work i still think you would be better off fitting a 1.3 manifold, gt cam and late spec polo 1300spi throttle body. you could also use the 1.3 ecu as a cheap way to remap it. match the head ports to the inlet manifold ports and you should see around 60bhp, 5 more than a std 1.3spi, plus its a shorter stroke so will fly.
if you are set on an engine swap the 1.6 out of skoda/mk4 polo running polo gt injection system is by far the best option, although an alternative block would be the 1.4 derv engine found in some mk3 polos and the seat terra van (its used by some g40 owners as its a very strong lil engine, plus you would still get cheap tax!)
