So i guess for carbs and throttle bodies what would be involved? Obviously an inlet manifold and the carbs or throttle bodies. Throttle bodies would require extra management in the form of? Does the original fuel pump supply too high a pressure? Would that need to be swapped? Would the original ECU need to be tricked to allow carbs or throttle bodies to run? 4AGE is such a pretty engine, it would look ace on carbs and imagine the noise right behind your head!(trying to fit them in behind the bulkhead would be the biggest problem IMO) I see no reason why a set of 40 DCOE's or DHLA's wouldn't work well on the 4AGE. RAW Engineering and plenty of kit car builders do exactly that. However, if you're a cheapskate like me 
then you can probably get round that by getting the distributor modified to run with a simple hall effect sensor, spark amplifier and a standalone coilpack. It won't be as tuneable as a dedicated ignition ecu, but it should work well enough. That's exactly what we did on the Escort to ditch the vauxhall injection system and ecu, to run the big rorty 45's 
(or triple, or quad!) sidedraughts on an engine at full chat! 
Just to add an idea... get a set of pretty agressive cams, ditch the TVIS and it would be a hell of a trackday screamer! I don`t want to run before i can walk but i`ve done a count up today of his carb to car ratio and there is a spare set of 40`s 
Good link. That`ll give me some reading to do tonight. Maybe that would be the best way to get the parts.

When i had carbs 15 years ago it was hard enough, i don't suppose it'd be any easiier now. Don't OMEX do a set for £1500 all in?- Circuit Pack 
, point is i had an engine, with head, cam , 4 branch tubular manifold etc , and most importantly a set of weber twin 40s ! the noise was ace best ive ever experienced and only inches behind the ear and on over run the poops and gurgles wow !! realise the fiat is frowned upon but carbs behind the ears are special it was even beta than the UNO TURBO CONVERSION that i did later , but it was a costly conversion especially buying parts new but worth while =D>Lauren wrote:I'd say throttle bodies are definately the way to go.
...(DHLA's and DCOE's both fit the same manifolds), grab a couple of decent looking DCOE/DHLA 40's from ebay and then buy the jets and chokes to suit them. Getting a custom ignition system together is pretty cheap too; hang out on the kit car sites and see what the 4AGE users are doing.£500. Carbs are easy to DIY install, too. Any decent old-school tuner should be able to get them set up in a couple of hours... those who know their stuff can even do it by ear, or with the aid of a push-on flow monitor. (chug, chug, burble.... stall?) Will it start if the temperature is -10degC?(won't?) afford modern technology. What are you going to do for a rev limiter?- Lauren drove it when it was owned by its previous owner, the stiff throttle was due to the p1$$ poor cable and linkage setup that was made out of bits of scrap metal, it was much better with a decent twin pull linkage. It was great in terms of the sound, but the driveability wasn't too clever. That was using an Omex mapped ignition and Twin coils etc. This made it much more driveable, but the throttle response was never that clean. Carb's run at 4 or 5psi and the FI pump in the tank will deliver 30+psi. Ideally you would cut the firewall and use the boot area as an airbox though. The brake vacumn was done using a tap off one of the injector ports while the others were sealed up using large grub screws..- sounds awesome but I never got it set up right. I will be breaking it at some point but it's not for the faint hearted! I may be interested in buying the manifold. I'll sell the whole kit and caboodle as one lump. No head work required.
