Title: a quick question
Post by: beattiemk1 on 31 August 2004, 18:27
i have a mk1 golf with a 1.1 engine, if i fitted a 2.0 8v on twin 45 carbs would i need to fit a gti fuel tank and pump?

thats a good question matey. thats got me thinking :-\
i would of said that you would only need to fit an uprated fuel pump as you are running carbs and they dont need the high psi as injection does........
try and get a beetle cros flow head if you want to stay 8v as these make the job a lot easier and better performance.

I think the 1.1 golf has differently posistioned engine mounts making the job alot harder.

So you recon i would get away with it? what kind of feul pump would i need like?

Engine mounts are takin care of already!

also would it be any different to fit a 2.0 16v on twin carbs?

if you went for the 2.0ltr 16v on carbs the job would be sooooooooooo much easier!
Firstly its a cross flow so the carbs get nice cold air directly from the front of the car with no exhaust manifold heat warming it up.
Secondly its a common engine in std. a lot easier to source than the 8v cross flow. so there is lots of tunning bits n bobs.
Thirdly it would sound fanfappingtastic! induction of the carbs and the roar of the zorst. plus all that power and torque in an ickle mk1! luvvly jubbly!

I think you would need a "pace" fuel pump as i think that is the make of pump i have seen on simlier conversions.

so i'd just need an uprated fuel pump? what about an ecu, do i need 1 of them?

i think engine management on carbs would be taking the conversion a little far  ;)

i dont know alot about the 16v engine in depth but as i understand it. the fuel injection was mechanical and there was a timing module to help make every thing tikity boo, but not as i would describe an ecu. to me an ecu is a box of tricks that controls all of the engine, i.e timing, fuel,injectors,boost and the like.

i would check the web and some magazines as i have seen this conversion done before so there must be loads of info out there. but if you keep asking questions here we will try to help you as best we can ;D

There are kits out there but they are a bit expensive.
Demon Tweeks do em for a bout a grand with the carbs. This kit includes and ECU to control the timing/firing plus sensors etc.

You will need some sort of control unit.

but i could run a 2.0 16v on twin carbs without a gti fuel tank etc?

Dont thing the actual tank matters, but you'll need the higher pressure pump for twin carbs.

It will depend on the fittings. Injection systems have a return system, dont think you'll need that with carbs.
