Was not sure if to Post in this section or alternative fuels- but anyway..

Just wondering roughly, how does the GRA setup work on the WINDSOR??

Is a Carby type Lower inlet Manifold required?? or is somehow the lower HO Converted to suit>>?? How is the air inducted/filtered?? Sorry if silly question!!!!!!!!!!!!!!!

Anyone with pics post em up Please, I'm very interested. :)

From what i have seen, these seem to be bolted up after the TB, so the inlet remains stock, all that happens is the gas is introduced at the same time as the air prior to the TB, if you understand what i mean

I got the worst GRA install done by a place in Carrum Downs.

Your TB will be replaced by the GRA TB.
I loose 2rwkw on gas compared to LPG.

They may change to the older style manifold if you go twin carbs. Not if you stay single.

Youd be better off building your own manifold top if that was the path and using something similar to the VN Group A Dual Sequential Setup.

That would have been MRE-50l. He was doing a straight gas swap and used a holley manifold as the intention was eventually under bonnet in the valley blower

i have a gra setup on my fuelly fseries the gra carby goes on in place of the throttle body and has the tps sensor bolted to the bottom and the idle air speed solenoid connected to it.When you arent on gas it just acts as a normal throttle body,i would assume a car setup would be pretty similiar.I got mine done by gra.They have a separate dept for gas fitting i think it was swift gas? they were/are in dandenong but they do have agents in sydney

;) it was a dual plane Wieand intake similar to the stealth model but I think he used an impco 425 and Holley base plate. (I am posting from my phone so it is in the to hard basket to find and link dave's thread)
