View Full Version : Converting GSi engine to Twin 40 carbs
how hard is it to convert a GSI engine to twin 40's and what will i need?
Not hard at all - budget around £400 for second hand bits and you will be OK.
If you want to go with ignition management this will creep up a bit
You need Carbs, Inlet manfold, alternator lowering block and adjuster, fuel reg and dizzy from a 1.6 Cav mk2 with vac advance.

First off you will need to have this moved to the technical section :thumb:
where would i get the alternator lowering block and adjuster?
and is the actual engine a straight swap?

Disagree with you there Will, I'd say more like £600 after having it setup.
Possibly - but I reckon I could get it all on and set up for that....
T40s with inlet £200 (I would wait for a set to come up - it does happen)
Dizzy etc £60
Fuel gubbins £30
Brackets (if its not included with the 40s) £30
Set up (bloke by me £30 p/hour) £60
£380 all in - OK I am really tight and wopuld wait, but its do-able.:thumb:
and then the engine on top of that plus rebuild which im capable of, i can do all the work for myself just need to know exactly what i need for the conversion, running a 1.2 at the moment so ...
You don't need to rebuild the engine unless it needs it, throw it in and see how it goes.
At least with a carb setup theres less fooking about with wiring
thats exactly why im doing in after having my x14xe ecotec lump in me corsa im sick of bloody fiddling with wiring
WIRING ISNT HARD!!!!!!!
and relax.
Will, the cav 1.6 dizzy is for putting carbs on a big block XE. You want the dizzy + ign module + wiring (oh noes) that go with it from the 1.4 carbed engine.
so i need a definate shopping list :)
2* 40mm carbs with a DCOE flange
1 DCOE inlet manifold suitable for the head you have (ie 1.6/1.4mpi, 1.4Carb/1.4 and 1.2 spi or 1.2 and 1.3carb)
a fitting kit of misable plates/thakery washers etc from raceandroad or similar on ebay
alt lowering bracket + adjuster
3psi fuel pressure reg
suitable fuel pump (facet red top etc)
1.4 dizzy + crap taht goes with.
GET THE CARBS REFURBED!!!!!!!! bent spindles and ****ty seals are THE biggest reason for all the crappy old wive tales about needing to get them setup all the time etc.
oh and a throttle setup for the pedal and linkage.
