Anybody know if the impco 225 is a good size for my 7mge?

I read somewhere its rated to 329cfm or 200hp.

IS there a bigger one that can be substituted??

See pic below.

i'm very lost on this. what's in the place of your resonator, is this what you're asking about replacing?

Yes the resonator has been replaced with a liquified petroleum gas (LPG) carb.

LPG is mostly propane with a little butane + da di da di da.

These conversions cost about $2500 in Australia but our government gives us a $2000
Back to the original question. Is there a replacement carb that can be just swapped in??

This one is an impco 225 rated at 329cfm. I would prefer to get one rated closer to 500cfm.

That is sick, I have done plenty of conversions for natural gas - propane - biodiesel - and all all that stuff before, but never once seen it done on a Supra.

I have no idea where I would even start to look for stuff like that for a Supra!

Good luck finding everything you need. Also I pray that you will get some good head life using that setup - dry gas likes to kill heads... its murder on them really.

a friend of mine in canada was running lp on his chevy k20, said he was getting incredible mileage (maybe 30-35mpg iirc). for reference, he's 6'4"

IJ may have some answers for you... He is running LPG in his 400-500+ hp 7M.
(Forgive me Ian for not knowing how much power you're making ATM. ;))
