Hey guys, i recently picked up a 87 Ram 50 2.6 litre and have been tuning and playing around with the original mikuni and I'm wondering if there is any debate over Webers vs Edelbrock.. i've read a few threads on here regarding the webers and that seems to be the group choice but if anyone has any input id love to hear it!
The Weber kit is the big selling point plus it’s a good upgrade VS the stock carbs, it’s an easy fix no clue about the Edelbrock setup.
I'm not sure Edelbrock even makes a carb small enough for these 2.0-2.6L (~122-160 CID) engines, and AFAIK nobody makes a suitable adapter to bolt one up to the stock manifold, so that'd need to be custom-fab'd.
Weber 32/36 DFEV/DGEV and 38 DGES swaps are the tested, tried-and-true solution with readily-available adapters to bolt them up to the stock manifold. They should offer better reliability, performance, fuel mileage, and emissions than the stock Mikuni computer-feedback carb, which should give you some idea of what a crufty kludge those stock carbs were.
The DFEV version is required to use a kickdown linkage for an automatic transmission, and IMO preferable even for a manual, as it can readily be mounted with the fuel bowl in front to minimize stumbling/stalling under hard braking. That said, I've got the mirror-image DGEV version which is cheaper and more readily available, tho' it puts the fuel bowl towards the rear unless you finagle routing the throttle cable towards the driver's side (e.g. by flipping over the cable bracket/pipe at the firewall and bending the pipe to route the cable clear of the brake master cylinder/booster). IMO the 38 DGES really only makes sense with a "built" engine that can make good use of that carb's greater breathing capacity.
Take care to get a genuine Weber, which should have a rough/dull finish to the castings, the Weber name/logo and "Made in Spain" cast right into the body, and (usually) an off-white plastic electric-choke cover. Chinese clones may be "licensed" but only in their general design and use of the name/logo, without the same precision manufacturing of the originals, which tends to make the clones tricky if not impossible to tune correctly (and keep in tune!) for all driving conditions. Clones have a smooth/shiny finish, the Weber name/logo only on a decal, tag, or ink stamp, and (usually) a black plastic electric-choke cover.

Some Mitsubishiz get Toyota carb conversion (in Philippines?) I have noticed my Mitsubishi searches on YouTube end with resulting videos from the Filipino mechanics ~ check it out :^)

Toyota carb adapted to another Mitsubishi ~ I don't speak their language BUT MAYBE they use Toyota new factory parts because they are in stock & available ~ Mitsubishi new OEM parts are hard to find https://youtu.be/F4kl6MF2SiY
Note: I recently got frustrated enuff with my Mikuni powered truck missing that I gave the carb several good whacks with the plastic screw driver handle ~ surprisingly the miss is gone now 99% of the time WOW

Looks like a Jeep/Renault 2.5 throttle body would fit that shape wise that jeep TB bolt pattern is close to a KM 145 shifter bolt down pattern.
