Turbo 4ac?

[Dom86]

nice catch can

how much boost will the stock carby take without blowing seals all the time

[Steery]

50 psi.

[shift_rook]

actually i heard that you have to flow at least 30psi threw then the pressure holds the seals in

i will be sure to try this lol. im thinking about just using a J pipe and a t25 then just run it straight into the stock carby. what else is needed?

[Konakid]

stock carby will fail

I still have the issue here. Look at it every now again, and think it would be cool, but a little unfeasable to do (for me). Its the ultimate question, pump up the 4AC, or take the amount you'd spend on that to go towards a 'better' motor (16V, 20V etc). Mind you, if you know what you are doing to feed the carby boost, then you can do it quickly and easily...

sorry to bring back an old thread, but i've been considering trying out the 4ac turbs (or bluebird L20 depending on what i decide)

mates got a TO3 i was thinking of picking up
done a few quick calculations but need some finer details on what other people have done in the past,

such as what have people done to the fuel bowl to overcome the pressure difference if anything....a plenum over the whole carbs is one way but is there an easier option??

an idea i had was plumming a small line from the intake into the fuel bowl to even out the pressures.....but then whats going to happen at no boost and you get vaccum in the fuel bowl....:o

why doesnt someone just slap on a supacharger on any motor?
im sure theres someone in the community with one spare... should be easy enough?

Not sure why people keep on talking about keep on talking about using stock carbys, there really not designed for this type of stuff. probably the most simple and efficient way to turbo a 4ac would be to use a proper turbo and carby, quite a few old school cars have turbo carby setups these would be really easy to adapt for the 4ac. Why waste your time with a t25 when for about the same price you could get an old school mitsy turbo with carbon seals?
