well my polo has now been sold for a few weeks and been on the hunt for a 3dr 16v mk2 golf gti, have just come across one but its on webbers, just wonderd whats the deal with it being on webbers when it's a GTi, i thought this was only benefitial on single point injection?

Probably a silly question.

sound, removal of engine ecu and sensors, can remove a load of engine wiring, they can give good gains over the stock injection setup, the gap is closed down if youve got a ported inlet mani and larger throttle body panel filter and driled airbox on your standard injection setup.

avoid webers and carbs if you dont fancy fettling or learning about them, if you love that kinda thing then get it mate, you wont look back!

i bet the valver sounds fuckin ace aT full chat!

drive it and you will see why they did it lol. power gains depend on what manifold has been used, most of them are of poor design which can mean you will see very little power increase, and (imo) 40's are a bit small on the 16v, 45's ftw.

i put 45's on my 16v scirocco, although i never got the chance to drive it with them on i got it running on them, they sounded fucking amazing.

they sound so good you wanna slap yo' momma!

I agree, twin carbs are fucking sweet.

Mate has them on his mk2 scirocco. sounds brutal :grin:

I'm no expert but surely even a pair of 40's is over carbing these engines? Massive carbs.

no mate, 40's are good to a point on them but if you want good power gains you have to go up to 45's, i'm no expert either but read up a lot about this conversion when i was doing it on my scirocco. i did most of my research on club GTI with a lot of it coming from people running track cars not show cars, so performance was key for them.

Weird, you would have thought with so many masive chokes they just wouldnt pull enough vacuum to work effectively.

Just done a quick googling and I think that 32mm is the smallest choke you get in a DCOE 45, which according to weber is apt for a 4cyl engine making as low as 140bhp (with one choke per cyl) so I'm guessing they are bang on for mild tuned GTI's.

Yeah 40s should be fine for most 16vs, what's the theoretical upper limit, 160 bhp or so on 40s? I'd be expecting about that for a 16v with a few light mods. If it's cammed much you'll probably be needing 45s.

I wouldn't say so, bikes I've owned in the past have run 4x 40mm carbs and they are only 600-750cc.

dub17 If the one you're looking at is located in Kent,which i know of someone selling it's a very lovely little car.Not too clued up on the webbers but it has had alot of attention put into fitting them i remember him having at all done not too long ago.

True, although bikes run CV carbs which AFAIK is a bit of a different science.

yeah they were saying that 160 is the limit for 40's but your not going to be a million miles off that on a 16v with just well set up carb's and a well designed inlet mani

I agree, a KR with the WUR mod, decent airbox/filter and a decent exhaust won't be far shy of that sort of power on the Kjet.

yeah dude thats the one. but will be goe by the time i can afford it, wont have 1600 until a few weeks yet..

Thanks for the reponse anyway poeple, going to be looking into it alot, will just get a valver, then if i want it carbed, will get involved and do it myself with alot of help.

The pros of twin webbers on 16v's are. awsome sound. tidy bay. power gains (but you need other mods to make the most of them (eg mappable ignition))

The cons are. bad economy. They do come out of tune easily.

They are not for everyone, particuly if your going to use it as your daily driver.

I think i will be doing this to my 2.0 16v mk1 one though

From what I've read it's all about a clean shell/body with a Golf MK2, because a clean base will allow any engine transplant you want in the end. There's so much knowledge in the likes of Club GTI and Golf mk2 owners more so than Edition IMO.

I've got a Big bumper 8v in the garage that needs quite a bit of welding but it is through neglect more than anything. I'm still pleased in some way because when it was on the road it had extensive servicing and hasn't been messed about by anyone.

While there is the 'scene' consensus that the 8v is inferior to the 16v which it clearly is in terms of performance I'm quite happy to roll with an 8v as a daily and have reasonable fuel mileage. Again I'd be keeping the 16v as injection unless it became a weekend toy where I would consider carbs but then again I'd probably get some far older school car for that.

I suppose good service history and the clean body will indicate a good car anyway.

If you've driven an engine with twin carbs you'd soon understand why, even though K-jet can fuel upto 190ish bhp with mods, i'd go for carbs at any engine tune. Its very different.

Smaller isn't always worse. Overchoking with some 45's will create a much worse engine for road use than a 40'd engine with good air speed.

I'm putting a 2.0 16v in my golf in the next couple of weeks, with a 4 branch, stainless exhaust, KR cams and 40's. Keeping them means i should have very good mid range and not so bad fuel economy. 45's would be needed for an out and out revver though, i already have the 40's etc which is another reason i'm opting for them. If they aren't successful i'll put 45's on. For a KR, 40's are very capable until other engine work.

Most people usually slate the carbs on a 16v, since they believe they don't make good power and are bad at town speeds, it's usually down to the half arsed manifold and the fact they are drawing their air through the radiator.

Arrrgghh i'm looking forward to it...............

^Now there's an example of someone who is a few hundred rungs up the carb ladder than me with my poultry Weber twin Choke lol. A great example of the sort of dedication,research involved and I'll bet hands on lol.

Respect, set up sounds like will go like stink

surely your gonna be well past the mark where 40's suited with that set up?

I'm not sure but I'm guessing that as a 16v will be quite a peaky engine, you will make peak power so high up the rev range that if you sized your carbs to work for peak power you would end up with an engine that in 70% of its effective range is over carbed. And stretching a smaller carb on may knock a few bhp off the top numbers, but will more than compensate further down the range.

Thats a good point about the radiator that twin40racer has mentioned. When i do mine i will be getting a custom made rad so that it is lower and wider so my carbs can get fresh air.

Cant wait

mine will be a daily, i would have gone down the carb route if i ended up getting a mk3 polo, but thats old news now, had my heart set on a mk2 golf for a good long while now. have done a fair bit of reading up on it, but not into amazing detail just the genral info about it and stuff really. maybe next year when i can afford to insure and run two cars i will carb my weekend car just wiating on an email back on an offer i put in for a 3dr 16v, but it has 21 previous owners and is a "88. so thinking its a bit suspect.. thats like an owner a year. but he has just spent £800 on a total overhaul of the car, maybe one of the many owners just couldn't be arsed and rather sold it for low price? what people think?

cars like this tend to have a fair few owners, some might of bought it and then found they couldn't afford to run it, others might of only intended to use it as a bit of summer fun then get rid. as long as it's in good condition things like millage and number of owners are irrelevant, you can use this to try and knock the price down a bit, but it won't even come in to your head when your blipping it through the lanes in it with a massive grin on your face

Cant wait

I wouldn't go to that extent, I'd just do some "temperature/airflow management"

maybe use a 1.3 golf rad? i'm pretty sure they are a lot smaller than the 16v one, although this may cause it to run too hot during a good thrash? they must have bigger rads for a reason?
