I have that very kit
I bought it as a bit of a risk... but am very very pleased with the quality of it. I've since got a few more bits through that company, they are based in Ireland, always very helpfull and gave me trade price on the other bits
The one thing the FMIC lacks compared to the like of HKS/Greddy are the "other" bits tha go with it, you dont get any brackets, replacement water res etc. Having said that they wernt too hard to build/borrow/steal, took me a day and a bit to fit it.
The quality of the actual IC is great, seems really well put together, the pipes are ally, which means they will probably look shabby after a while, you could coat them in something first if this worrys you. the connectors and clamps - considering the cost of the kit, are awesom! The silicon hoses are on a par with samco, and the clamps are the same style as mikalor (which i liked so much i bought a load more off of them for my intake pipework!)
To summarise - if you dont mind a bit of fabricating of brackets and fiddling about, get it bought
