hi Folks, need some advice , got a 2 litre blacktop with a st170 manifold onto two piece GSXR tbs think 600 ?its still got ford fuel system rail etc,the GSXR tbs have had the injector holes blocked off ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,now for the question My tbs dont line up with the st170 manifold any ideas,as cant split the TBs into 4 ,and the length of hose needed to sort this is too long.Looking at Bogg Bros making a manifold to enable me to use the Ford injectors and bits thanks folk
You have a few options as far as I see it:
1) sell your TB's and get some K1/K2/K3 (i.e. 2001/2002/2003) GSXR TB's. These can then be re spaced to go on the ST170 manifold using the
ford injectors. Bear in mind that the ports are a different shape between the standard blacktop and ST170 engines, so your ports won't match and
the injectors may be spraying at the head instead of down the intake runners.
2) sell your TB's and ST170 manifold. Then get hold of whatever TB's you fancy/are cheap (but haven't had the injectors blocked!) and
ask fast dan on here or Bogg Bros to make you a manifold to suit. That way you don't have to respace and you can use the bike injectors and fuel
rail.
3) ask Bogg Bros to make a manifold to take the TB's that you already have and the ford fuel rail.
I did number 3, but my TB's are respaced GSXR 600's. The manifold plate is 25mm thick and weighs a ton. It also came set up for a silvertop
engine, i.e. fuel rail with side feed injectors that didn't line up correctly with the blacktop head. I said I wasn't happy with it and
ended up sending them back the manifold, my cylinder head and blacktop fuel rail (!!!) to get it to go together how I wanted. It now looks sweet and I
had my reasons for going down that route at the time, but if I had to do it again I would go down route 2! I may get someone handy with a miller to
take some weight out of my manifold at some point, as it's annoying me already and it's not even in the car yet!
Hope that helps.
Sell the GSX-R600 throttle bodies and buy the early GSX-R750/1000 bodies that can be separated?
FastDan on here will make you a manifold to suit you should U2U him

Sell those and get one of this

Still made above 160 bhp with an emerald ecu

As said I will make you a manifold if needed to suit whatever spacings you have. However I am not currently set-up to be able to offer injector/fuel
rail mounted on the manifold, so my offerings require the bike fuel rail to be used which isn't really much help to you with your current bodies
me! Post some pics of your manifold 
Thanks folks ,now I have the single plenum idea bouncing in my head !!!anyone had much to do with these and how do they compare to TBs ?thanks again folks
big wasa on here is your man. The gbs one was claimed to make 166bhp with emerald ecu on the rolling road. Also claimed better fuel consumption
bit of a note the st170 and blacktop/silvertop manifold patterns (gasket area, stud postions and ports) are diffrent turst me i know now.
the st170 manifold needs modifying so its sits approx 5mm lower
