throttle bodies

i own a mark 1 golf cabriolet and at the moment im happy with performance munches the chavy saxos down lakeside but i have acesess to some r6 throttle bodies and want to put them on my car and was wondering what i will need to do this and if any one out there sets them up many thanks!!!

For a start.............electronic fuel injection......

ill start again lol im a total newbie to the whole mechanics side of cars so can i put these throttle bodies on my car on not? and if not what else can i do to my golf to make it faster?  ops:

are you sure there bodies and not carbs.
if there bodies you will have to run  engine mangement quite expensive even if you go for a diy conversion,
carbs will be easier less complicated and cheaper.

Honestly, if you want to improve performance, I'd ditch the throttle bodies and look at what others have done to most cost effectively make their car quicker. A good starting point is the "Engine conversions" article on the left. To start you off:

What model and year is it to start with?
How much money do you have (assume you can eBay the throttle bodies for a couple of ?, to add to the budget)?
What kind of performance do you want from the car?
Is it used daily, or is it a second car?

get your self some older bike carbs mate, then send them too
Bogg brother's who will rejet and supply you with an inlet manifold
 to suit your car. if you want carbs, id personaly advice for bike carbs, bit
easier to maintain than the DCOE's :wink:  you need pretty much the same stuff to fit DCOE's as the bike carbs mate

^if he's a total beginer at tuning, then I whole hearted agree with what Paul C is saying. Carbs are a challenge enough for a beginer and will yeild little withought other basic internal breathing mods.

TB's is a whole new world of hasstle and expense!!!

If you're motor is an 8v, then the best place to start would be with a 16v conversion and learn the basics of how to tune that.  

its a 1.8 8 valve, so where do i go from here how much are carbs and what ones etc???

Carbs aren't the magic bullet. They won't improve performance, and will cost a lot of money in the long run. By all means, go for them if you want a challenge, or like the look of them, or the sound. But for actual BHP gain, you need to filter out a lot of the stuff written on the internet (myths, folklore, call it what you like) and focus on looking at what others have done, which is not too costly and effective. Mk1s have been round a long time, and trends emerge which mean the effective mods become popularly done. So if you're not too familiar, just 'pick' a tried and tested route.

Nae a good 8v with mods will blow a 16v away from the mark, just sold ma old engine which had 147bhp. it all depends on what you want to do. old 8v on carbs is the way for sheer low down torqe and putting a 1.6 box in the car also will help up the off the mark go, but hinder's top end to 110mph.

if you wana get loads of noise and a big grin and becoming deaf every time you time you touch the go pedal, then get CARB's

But to start with fit a cam and vernier, 4 branch and 1.6 box :wink:

to me power graphs are PUB talk, what you do is get the car's on track, well my little 8v used to beat the pants of the 16v and the 20VT boys on track and down the quarter. it'a all about what you personally want. YES a 16V is faster at TOP END.  ill look out my video footage of it and you can tell me then that a 16v is faster :wink:

Surely a power graph is the actual scientific proof that the 16V is more powerful and has more torque than the 8V, and anything but "pub talk". Of course other factors such as gearing, weight, tyres come into it, but with these the same, which would be quicker?

And then when you introduce mods into each, things change again.

Looking forward to the videos!

Mk1 VW Golf GTI - 1.8 8v with Twin Carbs (DCOE) on Rolling Road - YouTube

Thats Mick's old engine before a rebuild, with a seriously blowing exhaust, crap compression, and basically a buggered head (which we found out about afterwards when he rebuilt the engine)

Yeah but no but year but no but year but……..

It's really a personal thing.

IMO, I'd say he'd be better off getting a set of bike carbs & manifold made up from Bogg Bros, that way he's onto a pretty simple plug and play system.

If he's a complete novice with mechanics, I certainly wouldn't advise an engine conversion.

You're right, in that if you're a newbie to mechanics, trying at an engine conversion isn't recommended. However it remains that an engine conversion (if you have the time, space, skill and the tools to do the work yourself) will be more cost effective than other mods which will increase power. Stock 8V + carbs is unlikely to achieve more than about +10bhp, even when properly set up. The K-Jet injection is pretty good, all told, and not worth throwing away just yet.

after some consideration i have decided to keep the mark 1 standard after reading thru all the posts as i am just a begginer im going to drive the car for a little while longer and get used to the feel and learn a bit more about the engine and its capabilitys as i already know it tears up little chavs in there saxos so im happy for the time being so thanks for all your advice but im going stick to modding the body work and lowering my baby before i play with the engine so thanks for all the advice.

If you want more power from any engine the first thing you need to address is have you got the fuel to match the increased inlet/outlet (flow)?
if you dont have the fuel you wont see any notable improvement! they go hand in hand every step of the way of in/out flow increases made by the tuner be it porting or increased size of inlet man,exhaust,or valves.ensure you have a much improved fuel profile with plenty of scope! do that and every other move you make is a benifit not a load of hot air as it would be with a standard fuel system, wether its 1.6 or 1.8 the series 1 xr3i 6.5 k/jetronic fuel system is the best swap over you could do and is pretty much trouble free! in doubt look up the 1.6 mk1 slick 50 racers from the 80s till?
