opinions on these throttle bodies

[hazlo]

Anyone seen these? Off an aussie site, also on ebay. They look very shallow compared to jenveys etc. So what arrangement would you need for best flow? And what diameter would be best? Guess youd need a manifold with welded on injector bosses too...

why not just buy the sandy brown colin satchel gsxr bodies.. proven to be the best on many road and race cars

bout £700 for a bolt on kit last time i seen them

[hazlo]

Yeah I've thought about that kit. I think youve got to get bodies on top of that price too. So these would work out alot cheaper. And as theyre the bolt together dcoe type I like the ease of fitting aspect which would be had by fitting these over other diy setups which use silicone joiners. So I was just trying to find out whether these would be capable of a smooth flow of air with the correct manifold etc. If not ill more than likely go with sandy and colins kit or the atpower kit

[blackie_2k5]

no im sure it was about £500 if you supply or about 700 if they do..but that was a while back and im not 100%

by time you add shipping and import duty.. and get an inlet made its not gonna be a huge amount difference...other then you havent got bodies that were designed and spec'd right for the engine you wanna use them on

[hazlo]

True enough. I didnt think about the import duty. Theyre on ebay for about 280 delivered. Suppose id have to get a fuel rail made up too etc.
