Mk2 Golf 8v twin carb conversion Help!!!

For the last 7 weeks i have been attempting a engine transplant from a 1.8 8v driver engine to a 8v k-jet gti engine. However instead of replacing the whole wiring loom i was persuaded to put twin 40's on it. I have put on a tsr 4 branch manifold, twin 40 dellorto's etc etc...

Does anyone know how to block off the injectors at the back as they are not being used thye keep firing out the pressure from the head when trying to start it.

Also the distance between the bulkhead and the carbs it seriously small. Brake servo doesnt allow me to put an air filter on either. So i presume i will need a shorter inlet manifold so tha carbs arnt as close.

Anyone got any suggestions as i really want my car back! [:^(]

 

here she is mid transplant!

 

And here she is, but without la engine! :S

 

cross flow head?

so the carbs are at the front of the car?

Could always leave the disconnected injectors in. Good temp fix..

 

oh by the way, whats envolved wiring wise to get the k-jet in? i have been thinking about it?

is it complicated, what else needs changin / replacing?

tim

 

i think pennies fit perfectly in the holes then screw the injector in on
top. i heard this on a forum somewhere so i dont know if it works or
not.

 

the carbs are at the back of the engine and very very close to the bulk head. Old injectors - 3 fit in, and last doesnt because of the vacum hose or whatever it is on the inlet manifold. thinking of getting one custom made but with it shorter and the hose hole put on the side if that makes sense.
cheers - guys keep the posts coming

 

as for wiring, you are using carbs so just use your existing loom.

 

the injector holes in the head are about 5mm

 

yer didnt wana replace the loom to a gti so just kept the loom the same and bolted some twin carbs on

 

so what advantages are there of replacing the origional lump with the gti equiv?

how much would the full conversion cost?

whsat sort of performance figures are you looking at?

tim

 

could i do this converison with a 2l block? a 2E for example?

tim

 

well i think the gti engine's are mosre capable of withstanding higher speed and pressures etc.
i paid 250 for whole engine and then lots on new 4-1 manifold, carbs, inlet manifold etc etc etc

bout 1300 spend so far inc bills from mechanics etc! expensive stuff. mostly coz ive been messed around thou unfortunatly and its still not done.

 

AFAIK the bottom end is the same as a 1.8 driver.
The head has slightly bigger valves and the all important gti cam already sitting there.

 

how were you messed around?

how much were the carbs/manifold?

did you get them new or second hand?

tim

 

i dont know, are u planning on putting a 2ltr bottom end on a 8v injection head with twin carbs, if u want 2ltr then u will need 45 carbs minumum. dont know much more than that, sorry

 

paid 200 for carbs off ebay 2nd hand, maifold 70 off ebay, you can buy the kit new but is like 750+ inc inlet manifold but you will still want to please the exhaust manifold

 

oh rite ok thats not too bad,

cheers for you wise words,

tim

 

im fitting carbs to mine the way im going to block the holes is to take the injector things apart and silver solder a head of a 8 mm bolt into the hex bit its fits a treat job done
