Twin IDF Carburetor kit

Description

New Lynx twin IDF down draught intake manifold and linkage kit to suit Holden Gemini with G series or 4Z series engines. – including linkage kit and carb mounting studs & gaskets.

With....

2 x Brand new reproduction (not genuine European) Weber style FAJS 40, 44 or 48IDF down draught carbs – with chrome ram tubes and fitting kits!

To suit the following:

Holden Gemini – models TX(1975) to TG(1985)

with G161, G180 and G200 engines

44mm carbs are ideal for worked 1600cc engines, up to mild/worked 1800cc and 2000cc engines.  However for stock 1600cc engines, the smaller 40mm 40IDF carbs would be a better choice. 

Although the intake manifold is designed for the G series engine in the Gemini engine bay, it can possibly be used in other engine bays, such as Rodeo or Jackaroo, Chev Luv, etc.  However we can not confirm clearance with brakes, shock tower, etc.  Shorter ram tubes or air cleaners might be required.

NOTE #1: This kit will clear the brake master cylinder and fluid reservoirs on all model TX-TG Gemini’s.  No swapping or modifications to the brake master cylinder or fluid reservoirs is required.

NOTE #2: Although we usually try and keep all parts for this kit in stock, we also sell these kits on our website, and sometimes we run out of stock, and it take 3-4 days to get new stock from our supplier.  So if you’re in urgent need of a kit, message us first to confirm if we have it in stock, otherwise, there might be a short delay in getting the kit sent out to you.

The IDF carb is a compact design synchronous carb sold to suit many performance applications.  It features ball bearing throttle shafts for smooth operation, and fully adjustable idle and main circuits, so you can have economical cruising, whilst still being able to get ideal mixtures for maximum power under full throttle.  The IDF carbs are hard to beat for bang for your buck.

As you can see in the photos, we have a large assortment of jets, and can custom tune to your application, providing we have the target specs. We can re-jet the carbs as part of the purchase price.  Choke size changes are an extra cost.

As with any carb swap, we can only take an educated guess at the jet sizes your engine will need, so even though the carbs should run quite well out of the box with the base jetting we supply, once fitted to your engine, fine tuning will be needed to optimize power and economy. 

We will contact you after purchase to confirm your engine specs so the initial base jetting can be calculated and installed.  This will get your engine up and running and should be close to what you need, minimizing fine tuning time and cost. 

Engineered Performance is not just an online store, we fully understand and use our own products, and tune them on customers cars.  We do not simply re-sell or re-box products, we individually prepare them for customers upon purchase, which includes pre-inspection, initial setup/adjustments and jetting of carbs/throttle bodies, and can offer practical advice based on first hand knowledge.  Consider this when choosing who to buy from.
