Any one here done it? how easy/hard is it?
I've never done it, but lots of people have. Most people seem to have success with putting the whole carb in a pressurized enclosure.
You can do blow-through, draw-through or what MG said. I don't recommend draw-through (has a tendency to wear the inducer, lost a t04 that way).
Lots of people modify carbs for blow-through (if you're a DIYer). You can also just buy one:
If you use the box that encloses the carb, you can use a standard carb, so long as the floats aren't made of weak hollow material. If that is the case, they can be changed.
There's probably no point in even asking this, but have you considered using a bolt-on fuel injection system instead? It's not like the method of fuel delivery is that important, except maybe as a principle, and if you're going to turbo any engine then you're clearly already cool with spending a four-figure sum on the project.
That pre made blow through looks interesting, but I don't suppose you have a link to a blow through mikuni side draft setup
here is a toyota 3TC with weber side drafts going blowthrough design
but even better, I found this picture on an older hybrid Z thread:
hmmmm....me thinks I could do the same with this setup
300ZT/TT here I come
thanks for the help though guys
Looks like an interesting project -- a Z isn't really an American car, but I suppose there might not be anybody in the Eastern Imports forum that knows shit about carbs.
You're not getting any benefit from the short-ram intake though; the reason why the car didn't come that way is because if the intake air gets sucked through a tube, it builds momentum that forces more air into the next cylinder that opens its intake valve. Your setup doesn't get that benefit, though once you put the carb-in-a-box on, along with all the turbo piping, you'll end up getting it whether you want it or not.
Also, why have you disconnected the crankcase breather? It's supposed to be supplied with vacuum from the intake manifold for a reason.
I get a kick out of how you talk like you've actually done anything you've read in a magazine practically.
I don't read car magazines. They're a complete waste of money. Now, if you're saying I'm wrong about what I said, feel free to explain why. Try to not wait until everyone gets pissed off before doing so.
I wouldnt even deal with carb. Switch it over to FI and you'll be much better off.. I know its expensive but its way more efficient.
Carb works though, dont get me wrong. You'll definitely want some type of pressure bonnet like described above.
I would either just go with injection or stick with blow through. Blow through is the best for carb/fi steups imo
