pressurized carbs?

Post by **w33dar** » 19 Jan 2007 03:03 pm

Hi, i just found a r-sport pressurized carb.. the parts included was: Turbomanifoild, mechanical fuelpump and intercooler.. i have a b200k.. the question is: (with limited electrical skill in mind) Can i just mount i right on? and do i need some other parts? like a turbo? f.ex.

and which engines have it originally?

any similar solution than this particular carb is also welcome

The R-Sport turbo kit carb is probably jetted for a B21, so you'll need a different needle. Other than that, it should fit right on. I hope you're planning to use a turbo with it, or there's very little point

cheers

Defo needs the turbo. You could rob that off 740 turbo.

The neddle would proably be close to start with - note you must use a turbo needle not a na one.

okay.. thanks for clearing this up

this might be a dumb question, but what needle do you mean?
i`m usually more used to Norwegian mechanical terms.. do i still have to use the renix system already mounted? or do i need a new one? and how much extra horsepower do i get from this?

(this is probably the most important thing) and is about 175-200 euros expensive for this kit? (without turbo)

You'll need to be able to retard the ignition when in boost, so standard Renix is out. Perhaps the Renix unit from a Renault 5 GTT would be ok? The original cars had a mechanical distributor - you'll be able to find a suitable one in a 240 turbo.

The needle we're talking about is the main fuel needle in the carb - the piece which moves up and down, attached to the diaphragm.

The price is ok, although not desperately cheap. At least the turbo is the cheap part!

you should also need the fuel pressure regulator , so you might need an aftermarket one for that

thanks for the help guys

this is quite interesting.. it don`t seem do be that much work after all.. at least it seems easier than swapping the whole engine

if you consider the electrical work involved with going from carb to injection

It's simple technology, but I guess it depends on how you look at it. There are probably more little problems to be dealt with - problems which don't have simple answers. Having gone down that route already, I'm now really fancying the 'complete swap' technique - once it's working, it works correctly!

At least the 'retro fit' stuff usually means you can get it up and running, then ironing out the lumps takes the time. I think that's what you'll find with the needle and ignition timing, etc...it won't stop it running, but it'll take time to get the full potential out of it. Still, it sounds like an awesome project

cheers

I don't know how much difference b21 would be over b200/b19 in terms of jetting, one could always up a boost a bit instead of putting less fuel to engine

But without a turbo it won't give much if any more power, turbo is needed and that has some work, oil lines and downpipe are perhaps things that are most difficult when installing.

okay.. anyway, the reason i started thinking about this is, i saw a 360 for sale on a site called autodb.no who also had a pressure carb. This was a couple of months ago. i would have bought it too if it had not been for the 3000 euro price tag.

it was a real sleeper. Brown, completely stock.

he claimed that the turbo setup alone set him back about 3600 euro

Hmm 3600, that would mean programmable engine management with fuel injection, turbo setup and everything inside engine would be new and balanced in here, but I don't know cost level in Norway.
