Sidedraft Conversion

[(DJGyron)]

Hi Guys!

Here's the deal, I've got a MK2 Jetta CSX 1.8 carb. I've got my freeflow and branch sorted and am making plans to fit a 276 cam on and have the carb head worked a little. I have a set 35 mil webers. I need some info on how to fit the carbs to the head and how to make the conversion work. My carb set up is the same as the pic below:

There are a couple things i need help with like

1. A thermostat like valve on the head that takes in anti freeze from a standard carb inlet manifold, whats that for and does it need to work if running the sidies?
2. The brass thingy on the sidedraft manifold, what fits over there?
3. Do the sidies need earthing?

1. you won't use this with sidies... just get a stopper and hose clamp and block off the coolant pipe that connects to the carb manifold.
2. this is for the vacuum pipe that connects to the carb manifold to supply vacuum assistance for your brakes. it'll work better if you tap fittings into the other 3 runners and connect them all up to the vacuum pipe with t-pieces etc.
3. no they don't

Hmmm...ok. And what about fuel regulators and high pressure universal fuel pumps, will i need these? Also, since the sidies are going to the back of the head unlike a crossflow head, the heated air will affect the cars performance somewhat. Any ideas on how to combat the heat issue and cold air inflows into the sidies?

you dont need a fuel pressure regulator, but you can add one id you like.

35mm carbs(i think its 38's) are not that big and if the budget is tight ur std mechanical fuel pump will do the job. u run 40's with std pump, no probs!

yeah there is not much space @ the firewall side. welcome to driving a u-flow head. u can run ur own air cool piping from the side of the fender or whateva creative way you can think of, i dont have a air induction @ the moment.

jetting & synconising is very important when setting up sidies! diy as far as you can, but get it tuned properly with correct sync'ing

Alright. Just a couple more things I need to sort out. Is there a place in joburg where I can get bolts made for my sidedraft manifold?

std mani bolts if fine

[Dj lost]

yep....sidies want hi fuel volume....not hi fuel pressure

[JOE_GT]

Just a few things to add in....

Step 1 -GET A FIRE EXTINGUISHER!!!
Step 2 -Get proper carb gaskets (Not ''Redline'') they last a month...
Step 3 -Get a proper stud & bobin kit to absorb vibration as this is the reason carbs are alot of work!
Note that the bobin kit prevents the gaskets from wearing out and the kit comes complete with the studs & brass lock-nuts
This was my setup a while back it worked well
PM me if you need a kit



Cheers

Good advice there Joe... well said.

Oh, and get an expert to tune them & set up the chokes correctly - otherwise you'll tire very soon of an engine that revs like a maniac when you get it going, but otherwise in the real world has poor driveability and terrible fuel economy!

[kingr]

the pic of that setup is neat

[pepa]

i had a pan on my sidedraughts.Speak to da rite ppl & hav one made up to take care of da heat.

[Dj lost]

what ar those in that pic, Solex sidies?

[kingr]

maybe, not sure. they defintely not weber's

[Dj lost]

Not weber or dellorto's. Must be solex's

[JOE_GT]

They are indeed -Solex the rare type..lol just buggars to .get spares and service parts for otherwise fairly simple to tune. I know of a clean set if u need some good clean revving carbs.

[kingr]

Solex carbs are good, i have driven a mk1 with them on. Goes well & sounds great. Not a weber sound, but you can hear that the "potte" is present

Howzit gents posting this on behalf of a friend he has a set of sidies on his caddy which he fitted recently but he needs to blank of a water outlet / inlet whatever in may be because he has a different manifold now any advice on how to blank it off few ppl said he should tap the hole if so what size tap and bolt shoud he use?

Hi there I'm trying to figure something out... I have a 2.3 vw mk1 that has side draughts on, but I'm afraid to run fuel through to it because I'm running a v6 petrol pump... I'm hoping someone could give me some assistance asap because I'm worried about damaging something... Thanks in advance

Find the contact details for RS performance. They are V8 specialist, but have the correct pump and regulator system that give 3 - 4 psi fuel pressure to the sidies. Any other pump and in your case the V6 pump will likely over pressurize the sidies and can cause fuel leaks or damage to the needle and seat and float bowls.

Tell us, how did you get to 2.3L. Fitting 2.3L pistons in a short or long block does not make it a 2.3L. What other supporting mods do you have on that motor?

I'm just finding out guys I'm doing a sidedraft on one of our cars but I came across a hole on the head which the standard intake fits over with a rubber o-ring what do I there to blank it of?

Tap that hole and put a bolt in it or Aluminium weld it close.

Hi guys, I know this is a late post but any help would be appreciated greatly, I have a 1.8 8v with 276 cam and 40 weber side draughts running on mechanical fuel pump on the block as it is a carb motor, however I'm having a issue with my sidedraughts I cannot get them to idle at all, they Rev up fine but can't idle, they simply die out no matter what any advice for me guys

First things first.
1. did you check both carbs and confirmed that jet sizes, float levels etc are the same.
2. When fitted, did you fit the correct gaskets between carb flanges and manifold?
3. Did you check that carb butterflies are synchronized and all 4 are open the same amount when in the closed position and when you pull the throttle open that all 4 are moving at the same time?
4. Did you set the air and idle screw the same on all 4 carbs? A good reference starting point is 1 and a 1/4 turn back from fully closed on air idle jet.

These are the basic check you can start with and then work from there.

[Yellowshow]

Thanks for this, I'll be sure to check everything out, we were not able to get the gaskets between the carb and manifold, and gaskets were made, but now I'm starting to think that was a bad idea, one thing that I did take notice was when the carbs are not sync'd the idle adjusting screw has a gap in between, the screw and lever and when sync'd the gap is taken away, and I did adjust them to 1 turn out on the air fuel mixture,, also I did notice even though they Rev up fine but if I want to take off it stays at a high Rev 3000rpm then I have to switch the car off.
