Hey guys,

I'm getting together parts to do a Straight LPG turbo on my carbie TB42.

What Impco gas carb would work best, I've heard of the CA225 and also a 300a. Any ideas?

I have spoke to impco and they told me they don't really make a system suited for a turbo set-up. Gas research are the way to go

impco 225 works as does the 200.

I have a 425 on mine.

It runs fine, no real complaints, no flat spots etc.

However I would go the gas research throttle body if I had my time again.

Much less restriction, and far better metering of the air. Just a better setup allround.

good luck.

Thanks for the quick reply, I'll look into the gas research systems.
