Getting ready to have a motor swap done on my 92 RS. My car has the stock 305 tbi A4 with an open element air cleaner...

I need to know EVERYTHING I will to swap to a carbureted ZZ4 crate motor. When I say everything I mean right down to gaskets and such. The motor comes pretty much complete I believe with a distributor, water pump, balancer and flexplate for an automatic transmission. I'll buy new plugs and wires before hand also..

I will need a carburetor... What brand/size should I get? I know I'll need a adjustable fuel pressure regulator. What should I do about the throttle return spring? Do I need new fuel lines for the carb or do they come with it?

The reason I need to know this is because I'm going to have someone do this swap for me and I need to supply ALL parts first. Forgive me but as far as this kind of thing goes I am totally new to this and have never even attempted this.

Is there anything I'm missing? Like should I replace my motor mounts? Will I need to buy something else to make my gauges and accessories work? What about the airbag? I'm keeping my AC btw...

I'm pretty sure my 700r4 will bolt right up. I know that my TC lockup will no longer function. I plan on buying a lockup kit after I get the motor installed.

I'd really appreciate any replies/help... Has anyone else done this exact swap?

I just want this to go smoothly and I'd like to have it done as quick as possible. I don't really want to run all over town buying little nickel and dime parts when I could have already had them.

Thanks and sorry for all the questions but I need some help!

 

There is no reason to dump the TBI and go with carb. You will need a holley TBI to Carb adapter sold through places like jegs or summit. Do some research on this site and ask JPrevost some TBI questions. Switch to 350 fuel injectors and knock sensor. Buy a $50 ebay laptop and some computer monitoring software. Adjust fuel pressure and timing to get the car running while you learn to use that laptop to burn your own chips. There is alot of good info out here. Keeping the car fuel injected will keep your gas mileage in the 20+ range and give good power increase. Again researching this site is the key. These guys have helped me tremendously.
