16v mk2 on carbs?

Im just doin a bit of forward thinking for a little project i want to do at the begginning of next spring. I really want to make a little weekend car out of a mk2 golf 16v. I want to run the car on a set of twin carbs as i just love the noise, and i wanted to know what sort of things i need to consider before i start buying parts i.e. fuel system etc, and also an idea of prices of carbs, getting them jetted if need be, and any other costs i've got to consider before i start

Any help would be most appreciated

 

hi m8,

second hand 45's can be had for around 300-400 depending on age/what they come with,and weather they have been rebuilt recently or not.

brings me onto the next bit of advice,budget for having them rebuilt unless you know they were definately done recently,worn/tired linkages etc are what cause the myths about carbs forever needing setting up.i think? a rebuild kit can be bought for around 60-70?

some sort of filtration,i prefer the filter socks myself,around 60 a set.

next you need an inlet manifold,available from various diffarent companines,around 150 or slightly more...obviously you want a new inlet manifold>head gasket too.

next things you want are a facet red top fuel pump 70 for a kit,which is best off being mounted as near to the fuel tank as possible.

a fuel pressure regulater around 45-50? you also want an inline fuel filter unless its combined in the pressure reg.best mounted in the bay,away from heat if you can.

you can use the original ecu for the ignition side of things or look at stuff such as megasquirt or dta etc...

you will need to modify/create a bit of piping for the brake servo take off too.

as for jetting/having them set up,it cost me 75 quid for the rolling road session and i never had to touch them again and it always ran perfectly,ticking over bang on 1k etc

Very useful neil!

Can you explain more about using the ECU to run the ignition?

Is rebuilding carbs very difficult? Have you done it?

Also how much i'm I looking at for getting the injector holes filled in some how?

Cheers

Andy

 

The injector holes are in the current manifold - when detached you will be left with only the ports so you don't need to worry about blocking the injector holes.

You can get a manifold from Rowland Manifolds South Africa (google it) something like 115 quid delivered (i got one) - the rand is good aginst the pound - speak to rowland he will help.

Riley will explain the wiring end of things as I havn't reached that stage yet.

 

Sorry, I'm being dense can you say that more slowly with more words.

Are Rowlands manifolds ment to be pretty good?

 

you dont have to worry about blocking up your injector holes as they are in your old inlet manifold, which you will be replacing, with a rowland one or simlar,

 

That's what I thought he said. Still can't get my head round that.

So the injectors 'squirt' into the inlet manifold, rather than the head. Yes?

 

correct,

 

from the donor 16v you at least want,

ecu.
tci (although a mk1 tci can be used )
coil,but again a mk1 coil can be used.

and the loom between this lot,inluding the loom for the hall sender on the dizzy.really you want to grab as much of the loom as you can and get rid of wires as and when you see fit.

forgive me but i cant really remember the specifics now,twas a while ago...

but basically,you give the ecu an ignition live (cant remember where from) the loom from the ecu goes to the tci,the coil,hall sender,and an earth to the rocker cover.

all sensors on the mk1's can be left as they were and still work.
as for mk2 im not 110%,but id imagine its the same?

ive never rebuilt carbs,but id imagine its pretty straight forward and theres probably a guide somewhere on the net.

and manifold wise ive not heard anything bad about the sa sourced ones,if you get one from tsr its worth checking it for straightness and flatness

neil.

 

Cheers again Neil very helpful as always

 

Hi, what kind of bhp do you get from a 1.8 16v with manifold ss zorts system and carbs?<?:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" />

 

less than you get from a stock one on K-Jet......

really fitting carbs has to be the worst way to spend 500 on your engine. a 2.0 block and ported head would be a better start

 

It falls on deaf ears Prof, save your breath.

 

not with me!! i thought about it but now have a 9A 16v with KR cams and 42mm inlet manifold....... oping ot get about 170bhp and more when i can afford a ported head.

I just think K-jet is more reliable!

Thx Prof, I was considering head work & cams to start with but I thought carbs would possibly be a better option. What bhp you reckon on both builds approx, and have you had carbs before, cheers.

 

carbs may give more torque, but GVK made 170bhp with a ported head and 2.0 block on k-jet

 

Carbs will give a much broader spread of power and torque (partially due
to K-Jet fuelling limiting the ignition advance which can be run without
pinking) but hardly anything in peak terms. A 2 litre block would be first
on my list but there would be some gain from carbs after that, especially
with a ported head. Make sure you find someone trustworthy and
knowledgeable to tune them though.

 

but if say you have 500 to spend a 2.0 engine is the best bhp/ you can spend

 

Definitely.

 

Where`s all the carbed 16v RR plots? seem very few and far between..

I`ve got an `89 spec 16v loom and ecu kicking about..
