i know asad used gsxr 750's. are the 600's any good or another makes suitable too

these will be fitted to what i have now found out is a st170 inlet which im happy about as its get the injector holes i wanted

Asad's the man to ask or do a search and check his recent post, very detailed to

I had a set of these a while ago: GSXR 43mm



They came with what can best be described as rubber 'boots' that originally joined them to the cylinder head on the bike. They make fitting a doddle, fabricate a manifold using a Zetec head flange and pieces of tube welded on to connect to the 'boots'- easy!

oh asad post been a great help for me, [ERRR] made me look for st 170 inlet. i know he has used gsxr 750's but was out bid on a set. seen some 650 and also wanted to know what else would fit like the 750's

if not ill keep hunting

How much do they cost, and what power do they give (soz to hijack)

[Asad]

Hi,

Mine were from a GSXR1000. They are 42mm TBs.

I believe that the GSXR600 TBs are 38mm.

You should be able to get a decent set for around £80.

[ant pittaway]

excursion, i had them off you , mines nearly done, im also using the st170 inlet and injectors, they just need a bit of modifying

What kind of power difference do they offer? also, do they use a hell of a lot more petrol?

[RS_BOB]

ant pittaway - looking really nice, im guessing the header you have got is from the states? will it be custom piping to attach it to the rest of the exhaust system ?

Asad - once again cheers for your help and information

that looks the nut sack, I've got the same headers n down pipe, I've got some r1 throttle bodies in the pipe line, Would love to see this running

[Asad]

Im using 330cc injectors so yeah it does drink a load of petrol. Im geting around 40miles to £10. But that is with giving it a bit of a caning! I havent got the art of economical driving sussed yet!

I'd imagine it would be more petrol friendly with standard ST170 injectors, something which I may put back on.

As for the header, there is a UK seller on Ebay - search for "obx focus" on ebay and you should find it. Seller's ID is nautica35.

Hi All

Can someone tell me if i deffinately need an inlet and outlet to a fuel rail when using GSXR750 tbs on an ST170 engine?

Regards: Navi

[heeman10]

Yes you do. Fuel pressure will be controlled by a fuel pressure regulator, which requires a fuel supply and a fuel return back to the fuel tank. Throttle bodies require a regulated high pressure fuel supply to the injectors, unlike carbs.

[fwr48t]

Thanks heeman10

Thought there might be a chance because there is only a supply connection on the throttle bodies i got off a bike.

Hit another set back today with a trial fitting, the alternator i got from Retro Ford is hitting the tbs and manifold i got made from Bogg Brothers.

What to do now?????

[Si_2000]

soz for another hijack but what controls the idle when useing throttle bodies? something that i thought about the other day whilst trying to find managment. thanks, tom

[ads_t]

ant pittaway, what exhaust manifold is that on the engine, where can i get one??

thanks

[krestudon]

I have seen exhaust manifolds similar to that in ebay america, for their focus 2.0. dont know if it's engine is a black top or a different zetec.

do anybody know if these american manifolds will fit european silvertops? and going deeper, anyone knows which are the diferrences between euro and american zetecs? can i buy arp cam/head/con rod bolts from usa? and vernier pulleys?

[SiZT]

its an OBX manifold, look on ebay for 1.... only major difference between Euro and USA Zetecs is the inlet manifold AFAIK

[Oranoco]

These are my mates, as supplied by Bogg Bro's



In place

i wrote up a guide on my site for using the st manifold and gsxr tbs
