1.6 gsi to carb

[squeak]

i got a 1.6 gsi engine inn my nova want to put normal 1.6 cavaliar carb and inlet onit but there is a little hole inn the bak of the block what could i do:confused:

[mowgli]

what sort of hole?
is it the 'conrod thru the side' sort of hole, or the 'there is this strange hole made by gm' sort of hole

Also, why do you want to get rid of the injection, and fit a lower power carb?

[squeak]

well coz its doin head inn trying to get my car started on injection lol its a gm hole direct at the bak in the middle the egu valve covers it wen the injection manifols is on

[mowgli]

make a blanking plate from some steel or ally plate & cover the hole

[therealnovaboy]

i think i know the hole you mean is it lik 15 mil or somthing, the manifold should cover it, i think the gasket covers it.

its a 12mm hole the gasket dosent cover it neither the manifold coz the cardbretter manifoldis slightly different

[mowgli]

If it is round, get a core plug from a decent motor factors

[therealnovaboy]

oh,well if the standerd manifold blocks it chances are its ment to be blocked. is that not the hole thats there to reduce emissions or something,that rally build manual tells you to block it i think. dont take my word for this,it just rings a bell.

Tap it and fit a bolt.
Its the egr hole.

No carb inlet fits a gsi head properly tho....
