Hi, I'm posting this on behalf of a friend who has recently purchased a Mk2 golf 1.6 driver. He wants to put new carbs on it. So I'd be grateful for any help that i can get. Need to know what carbs to put on it and where to get them from and roughly how much they'll cost.
Thanks,
Ben

Use bike carbs - they hardly need any maintenance, easy to set up, produce better power and a better spread of power because there's choke per cylinder.
Or twin 40s (Webber, Dellorto) just the same as above but apparently they produce more power - but also use more fuel.
Fail that just go for the Webber replacement (single) carb which will fit strait onto your mainfold.
-
Thanks. I'll let my mate know, how much would twin 40 webbers set him back?
-
With everything needed to fit them? I would be most greatfull :grin:
-
I got a set of twin 40's a while back that i paid £200 for, plus then you need the inlet manifold, the linkage if you havent got that and the of course air filters for them aswell, not cheap!
plus they are a pig to maintain and would use more fuel than the QE2.
-
Fuel is just something i dont worry about, pump it in have a laugh go fill up. Always is gonna be the same you gotta pay for fun. How much are all the parts i need then? Could i fit them myself?
-
ok its not cheap , you'll need a good £800 at least , also to set up takes a lil work , also you need to bypass the fuel pump im not sure on golfs but id imagine you just remove the one underneath and use a hose in place , the one in the tank would need a similar mod as my 205 had , which was to remove and replace with a pick up pipe of similar length , you then install the facet fuel pump as near to the carbs as posible (the space where the air box went is ideal.
you need 2xweber or delorto 40 carbs , a inlet manifold , a facet fuel pump , a fuel regulator/filter , fuel piping and union connectors , a small filter for the breather and two large filters for the carbs. also if you buy them brand new or second hand there gonna need to have the right idle and main jets also venturis need to be the right size. this is what cost me the most to get right , i spent a fortune rolling roading it , changing jets till i got the best performance. it spent the whole day at a weber specialist , which aint cheap!. is it worth it? , yes! , my 205 on twin webers was a arse ripping laugh , it never failed to make me smile when i heard those carbs roar , its worth having a race head built for them btw , i had a 275 cam and a gasflowed/skimmed n port enlarged head. my low to mid range was scary. 6 sec 0-60's were no probs , fuel wasnt all that bad either :) , only prob with the golf is its inlet manifold is on the back . imo 205's are much better suited to carbs because of there orientation.

Not worth doing anything other than fitting a Weber 32/34 DMTL, get one on ebay and a GTi cam, it'll run nicely, and keep the std airbox as the weber suffers from carb icing if you don't. The DMTL is good to fuel up to 150bhp. The DCOEs (twin 40s) are only any use if you've done some serious work on the engine, on a std Driver a complete waste of time.

I got me a set of dellorto 45’s for £120 (going rate) around a month ago, serviced them (£20) got a second hand filterking filter + regulator + facet red top pump, all mounted on a all in one fabricated bracket for £120 from turbosport. The manifold and any other accessories you could wish for can be obtained from http://www.racecar.co.uk/dellorto/.
Where do you live as thereÂ’s a few cracking carb tuner around the south east that are reasonably priced?
Do it you wonÂ’t regret it!

So with a GTI cam and a Webber 32/34 DMTL it'l run 150bhp???
-
I said a DMTL will fuel up to 150bhp, so you could tune the bejezuz out of a 1.6 and not need anything bigger or more complex than a DMTL. And to get 150bhp out of 1.6 Driver would cost an eye popping amount of money. The point is you'll get around 80-85bhp on a 1.6 Driver with a Gti cam and exhaust and the DMTL. If you fitted DCOEs (pair of Twin choke side draughts) or Dellorto equiv onto an otherwise std Driver you'd probably succeed in slowing it down and half your mpg into the bargain. Twin chokes are designed to work well with high reving tuned motors. With a lot of work you could possibly detune them so a std motor would run okay but you'd go no quicker and still suffer in the mpg stakes.

I got 106bhp @ 6300rpm out of my old driver with cams, standard carb (with bespoke air intake), advanced ignition timing and no other real modifications, just correct set up. So there is scope for these engines.
I would say go with the DMTL as it's easier and cheaper but there is alot to be said about having a choke per cylinder and if your serious then twin 40's or bike carbs are the way foward.
-
Mine cant be standard then if 80-85bhp is available through adding an exhaust and gti cam as i took the car down a runway against a Saxo VTR 98bhp model, i had a bad start spinnin but once i got traction i pulled on him.The Saxo surely weighs less than the mk2???
-
Not a lot of differance - Saxo is 1996lb and the Mk2 1918lb. I wouldn't put to much on one run, in std form the Saxo hits 60 in 9.3 and the Golf in 10.9.

Man you know everythin!!! lol How much difference would a gti cam make performance wise?? and what bhp is my car standard then?
-
Also where can i get either a 4-1 or 4-2-1 manifold for my "driver" lol ive named it gerald :grin:
-
Man you know everythin!!! lol How much difference would a gti cam make performance wise?? and what bhp is my car standard then?
mark 2 1.6 drivers are 75ps, and putting a GTI cam would be quite benefitial too. Would pull a little bit better and have more puff higher up the revs.
-
id stick with the pierburg get it set up correctly and add a gti cam works a treat.
-
Would the gti cam just drop straight in? :rolleyes:
-
yes, straight in
-
Just had a thought.... What about like a GTI high lift cam??
-
or buy a GTi, by the time you've done this you'll insurance will be through the roof.(IF you declare it...)
I had a 1.8 Driver for a few months, as i turned 18. I dreamed of doing all this stuff to it, and making it so much quicker. Added up it'll cost a bomb and ALOT of effort. So i went out and bought a GTi. Then you'll need to do the brakes, then you'll have to sort out the handliing.
I know it's a sore point, but i'm so glad i bought a GTi and got rid of the Driver instead of wasting what would've been loads on it.
Or failing that, covert the Driver to a GTi by changing lump.
-
I know what your sayin mate, the car was bought for me. I dont mind all the work its the only way to learn really :rolleyes:
-
i have heard good things about using a GTI manifold and down pipe too helps
-
Having looked for a GTi I ended up with a 1.8 Driver and I quite like the simplicity of the carb - I've experienced both Digifant and K-jet misbehaviour and fun it isn't. A Driver like mine with GTi cam, Weber carb and GTi exhaust is not far short of a GTi anyway (around 105bhp). I will change the manifold and downpipe eventually but only when I go 2L and put a ported PB head on it. As you might have noticed Golf owners just can't leave them alone! I could get a 16V or whatever but I quite like tinkering with mine and none of it has been really expensive, buying stuff off the forums and Ebay and doing all the work myself. And every mod I've fitted is removeable so if things change I'll break it.

new to the site and have a 1600 driver as well.cant seem to find bits like manifolds etc for it.was reading this and was well impressed as this forum actually has people that know what they are talking about!!so do most bits from an 8v gti i.e. the cam, exhaust manifold etc fit on the 1600 driver engine?
