Hi all,
There's a lot of information out there regarding conversions, so much so, for the relative mechanical novice it's difficult to decide how best to go! I started down this path, the original idea being a 2L conversion of my std 1.8 GTI Cabrio.
I've got the AAG block for the conversion and have now decided I'd like to go down the route of twin carbs. This is not in pursuit of heaps of power but more the desire for simplicity, being in my 50th years I guess I prefer my fuel air mixture to be prepared, mixed and delivered mechanically and without the aid of electronics, I'm not seeking to create an engine that will be king but maybe a prince amongst men ;-)
For those that understand this sentiment I always remember the RS2000 engine where you opened the bonnet and look at an engine that would completely cane most things on the road but you could almost step into the engine bay with it, it's that sImplicity that I'm after;
RS2000 bay
Anyway I'm drifting. I'm trying to better understand the pros and con of this project (and the cost implications) so would like to try to build a "How To" from you knowledge here on this forum, selfishly for my on benefit but hopefully for the benefit of other.
Plan A - original head to AGG
- dbilas manifold and twin webers
- 4 branch exhaust- Heat wrap manifold
- Replace fuel pump with a facet or similar electric unit
- remove the accumulator and all the old fuel lines, replace with rubber pipes
- use the factory relay and wiring to power the facet
- Block injector holes either, injectors in to block the holes, drop coins under the injector inserts, or use gearbox drain/fill plugs, there may even be a kit out there??
- TSR tsr dizzy adaptor, swap the 2.0 dizzy gear to the old dizzy and drop it in
- Think there a TSR blank plate as well
- Loom, plug it in as it was before, and bin off all the left over plugs once you're done.
I am going to port and polish re cam which ever way I go but want to focus on which option is the most practicalSo first question what have I missed???
My thoughts re the above are that the induction is inches from the bulkhead, the air flow will be restricted and hot and maintenance will be a *****!
Plan B - And the first question is "is this possible?" AGG with AKL X flow head (MK4 1.6)
- Will the AKL actually fit?
- Does the oil drain need to be reworked on the block it's round -v- an oval on the AKL head?
- Is there an exhaust manifold that will fit the car?
- An of course what are the other issues??
Thanks!! J
PS Don't want to go bike carbs either ;-)

Quite an interesting project but would not the 2 ltr 16v engine give you what you want and be much simpler?

LOL did you read the 2nd / 3rd para - The heart wants what the heart wants, there's no logic to this :-)
