i have an NA LPG datsun 310. Someday to be a turbo

Yeah sure,

GT25 Turbo blows though a front mounted intercooler then to the GRA ( Gas Research carbi and into the motor though the modified EFI manifold.

The key to the system is getting boost presure onto the back of the gas converter so that it will release gas when the engine is under boost. ( the orange pipes do this) they allow boost presure to be pulled from infront of the turbo adn infront of the thrttle body this is then joined and then applied to the back of the gas converter. Also for good throttle responce you should hasve the gas converter as close to the throttle body as possible that is why it is mounted on top of the rocker cover.


The GRA is a gas throttle body with a metering rod and idle jets so you can turn it acurately.

cheers

some vaporizers have a pressure balance port for using in boosted apps. I picked one that does made by OMVL in italy.

it uses a variable piston mixer, kind of like the old SU carbs. It seems to work good.

dig up my documentation there's lots of pdf's and such on lpg devices.

yep correct the mixer / converter that I used was known as a B2 mixer it has a port on the top lid for applying presure in boosted applications this is connected to the orange pipe, the gas carbi is from:
GRA

cheers

Thanks for the help

LPG + Turbo ! ! ! - a must try soon .

lpg turbos are probably the easiest to make.

Very true they are easy the first version I bought for $800 and came with a LPG hat on the front of a CT20 turbo and a butterfly on the manifold and a scary boxed exhaust manifold but surprisingly it worked well just took a while to spool up.

wouldn't a nice turbo look good in there?
