EMPI Dual Weber 48 IDA Carburetor Kit — Standard Manifolds with Hex Bar Linkage | VW Type 1 (43-7328-0)

The Weber 48 IDA is the carburetor of choice for serious air-cooled performance builds — drag cars, big-bore strokers, and Type 1 engines pushing 150+ horsepower. This complete EMPI kit pairs genuine Weber 48 IDA downdraft carburetors with everything needed to bolt on a no-compromise induction setup. No more mixing and matching parts to make a kit work.

Kit Includes

• Two genuine Weber 48 IDA 4R carburetors (pre-jetted, 37mm venturis, jet screens installed)
• Standard length aluminum intake manifolds (clearanced for stock heads, port-match ready)
• Round bar Tayco competition cross-bar linkage (EMPI 43-5240)
• Aluminum velocity stacks
• Steel mounting brackets (allow optional air cleaner use)
• Fuel line, brass tee fitting, inline filter
• Manifold gaskets and complete mounting hardware

Why 48 IDA Over HPMX / IDF

The Weber 48 IDA is a true downdraft design with massive 48mm throats — significantly larger than 40mm or 44mm sidedraft alternatives. For engines over 1915cc, big-bore strokers, or any build targeting peak top-end power and RPM, the IDA is the racing standard. Below that displacement, an HPMX 40/44 or IDF kit will make better street power and drive smoother.

Fitment

• VW Type 1 dual-port engines, 1915cc and larger recommended
• Beetle, Karmann Ghia, Dune Buggy, Sand Rail, Baja Bug
• Will not clear stock fan shroud without modification — 36HP-style shroud recommended
• Verify hood/decklid clearance before ordering

Shipping & Box Size

• Approximate carton: 24 × 18 × 14 inches

• High-value kit ships fully insured with signature required

Installation note: Air cleaners not included (sold separately). Single carb applications require a vacuum-assisted distributor for proper performance. Tuning a 48 IDA is more involved than a stock carb — be prepared to dial in jetting for your specific engine combination. Professional tuning recommended for first-time IDA users.

Pairs with: EMPI Pro-Sync carb synchronizer (43-5712-0) for proper dual carb balancing.
