Thats nice. Yeah too bad it's for a 1.8.

I sent him an email the day it came out and haven't gotten a response

 

wtf is an IRTB? Individual Retard Throttle Bodies?

 

individual runner throttle bodies

 

r = racing.

 

I guess its cool for the price. But it kinda looks like a rigged pos.

 

^ What throttle bodies do the Fuji racing ones use?

I wonder if he ever posted vids of it in action.

Its a steal for 550, I think.

 

Intriguing setup indeed, but looks like hammered **** IMO, wonder if I could build my own to look a little better than that. Is it even worth the hassel over building a normal IM with one TB and just larger runners?

 

Why would you need larger runners on a car that already has a turbo pushing air down its throat? If anything you need smaller runners to improve off-boost operation.

 

Large single TB and short runners FTW.

 

To match your ports...
It only makes sense that you would want your runners to be as big if not bigger (diameter wise) than your intake ports, that way they are not a restriction.

 

its not really worth it,been there done that,its ok if your motor is fully built other than that not worth it too much work for few gain hp and torqe and that itb they sell those at gsxr forum everyday for $100-250 and gustum flange for 200 at local metal work.not worth it.

 

fuji use brand oer from taiwan,harware are verry fragile easy to strip.plastic vacuum hose not recomended,piggy back ecu not worth buying,just go with mspnp,youll be happy only if your 1.6 it built.

 

I did not know that the runners are sized smaller than the ports. Strange.
