fuel injected quad throttle bodies

Looking at puting a set of injected throttle bodies onto my pinto. Ive done the sierra thing before and found it reduced the power. Ive seen some good looking ones on the internet but are a little confused with the size of witch one to get. Would the same size twin side draft dia be the same - say 45mm. there are a set there for $1500 with out manifold. Any ideas on brand or accessories to match. Links would be nice!

Try ebay US and search the motorbike throttle bodies. I too ran Sierra injection and didnt like it. I've been using 2004 Suzuki GXSR1000 throttle bodies for the last few years with good results.

how would you compare to webers for stock performance. what computer are you running

Never ran twin webers though have driven a few Escorts with them. I can't give you a before and after type answer but tunability of injection is far greater so drivablilty really should be that much greater too.
I run a EMS 4424 Computer.

Can you post some pics of your install to see how it sits and looks
What did you use for the air filter and manifold

Started with a custom manifold, now using a modified twin weber manifold. Don't run filters most of the time. Did have redline socks on it for a while. Also made up an airbox to suit but no longer use that either.

Cheers

Throats are 50mm tapering down to 42mm. EMS is aftermarket. Sierra EFI dizzy.
