View Full Version : carb
what carb will be better to run on my engine at the mo i have a 18cav carb on with a p/phead and manifold 4 branch ect will a 32/34 be better ???
cheers ad :D
What size is your engine? Everyones gonna tell you T40s so i'll beat them to it
Go for T40s mate. :lol:
its a 16 gsi carbs are a bit costly at the mo tryin to get a house other wise twin 40s would be a must :D
Lol,
To start with rip that carb off, and put he EFI system back on :wink:
The standard MPI system is miles better than a single carb, you will be losing power with that carb fitted.
Either go t40s.
Or put the MPI system back on.
Just leave it as an injected unit. Far simplier. As for the house, me knows. Signing the mortgage on Thursday!! :lol:

thirded, EFI is the way to go on that motor unless your gonna go for ITB's
single carbs are a useless waste of time and when the engine comes with EFI theres no point removing it to fit some shite old carb
and dont start with the crap that its difficult to wire in an EFI system, its 6 wires a fuel pump and tank, not the most challenging of operations ever

you can put mre power than 2x40's whit EFI bur you have to do some thing inside it
was told today that wirin the gsi loom in is a full strip down in and out of car but surly u can patch it in to the sr and as for the fuel pump im runinn a facet fuel pump and filter king press reg any idea how to wire up gsi loom and obviusly ill have to run all the ignition system to
cheers ad :D

Temper temper. Just think, we all need help with things as well, something we're misguided and need help from others, please bare that in mind before shouting at us and making us cry like bitches, sniff, sniff!!!! :oops: :cry:

the EFI loom needs an ignition live and a permenant live which can easily be obtained from the battery and ignition barrel
it also has outputs for tacho on dash, engine management light and fuel pump
the facet redtop is no use for an EFI engine as its not high enough pressure
either find a GTE/GSi/SRi tank and GTE/GSi/SRi pump
or get a 1.2i tank and fit a mpi pump from a cav/astra/corsa etc to it
the engine loom is self contained, it connects to all the injectors/sensors/dizzy/coil etc, the only connections back to the car are those listed above which are on a multiplug that sits next to the wiper motor
facet pump not good enough to run gsi i know loads of people runnin them on 2l, twincarb engines allsorts its a comp fuel pumpaint it :D
lol you have just answered your own question there lol
"twin carb" the faceet pump is used with like you say carbs
its now where near the right pressure required for mpi systems

exactly, the facet pump could prolly make 8-10psi at most
the efi system wants 3 bar which is 45psi
sound m8 so is it worth it spendin the money to get all the req to convert to injection or should i just save and get t40s but the house comes first (just incase the missus reads it ) :D

i'd go for webber 32/34 on the 1.6 and jet it good. 8)

yes and then you'd be wasting money on a shitty carb
if your wanting 40's then fit 40's
efi is substantiably better than 32/34 or a 2e3 will be BUT most cheap tuning for the 1600 motor would involve twincarbs so make your mind up
Right, i've been watching this post very closley. So when wiring up an EFI, all i have make sure everying is wired up to the engine and take whats left of the loom and plug it straight into the Dash, and thats it?

Yes.
The 1600 engine loom just plugs in, instead of being permanently joined to the car loom.
So you just wire the loom up to the engine, then plug it in the car end.
I think :wink:
but isnt that only if you have injection allready ??? when i stripped my gsi donor car i unplugged loom but there is no where to plug into the sr as it is a diff loom :D

Will it work on my 1200i though?

Hmm, i can't remember if SPI looms are also built into the car loom, or self contained.
I think they are in the main car loom like SRIs.
Dont quote me on that tho :wink:
Addgsi-That is why people swap the whole loom, so that the car loom has the connector for the engine loom to plug to, as you wont have it if your engine is carb.
If you keep your loom, you would need to cut the parts off the donor car loom you needed, and then wire them into your cars loom.
