I called a breakers today and as soon as i said i wanted a set of gsxr 750 bodies for a car he said £180 +vat and non negotiable.Needless to say i
didnt bother.
I am now thinking about my original plans to make patterns and get some cast , I can machine them myself but have to decide on what bore size to
use.
It seems as if i may be able to produce them for a price in the region of £200 a set for the basic bodys plus the linkage.They would be individual
bodys with weber flange sizes, and an air bleed adjuster on each one.

For info, I asked one breaker what bore size the 750 bodies are and the reply was 42mm. I know from previous chat on this that the 1000 bodies are
44mm dia.

Adrian,thanks a lot for telling everyone and his dog about the item I happen to have the highest bid on.
Unless you are are willing to pay £150 + dont bother bidding against me as they're exactly what i'm after.
Anyone play poker?
I'll warn you I used to make a living buying cars at auction every week!
Once I've finished a project why do I start another?

Standard Car injectors can be fitted, but you'll need to remount the fuel rail.

PS The US Ebay Site is where I got mine from - less than £100 *including* shipping from the US.

You be surprised - don't forget that they are designed to flow much faster due to the bike engine revving much higher, e.g. a if Gixxer 600 has
a redline of 11k RPM then you'll be able to run a 1200cc car engine at 5.5k RPM without stressing the injectors anymore than they are in the
bike.
(PS don't actually know what the Gixxer engine max RPM is)

Right guys, I could do with some advice. Which would be the better throttle bodies to fit to an xe? GSXR, Blackbird, or other? Anyone know any
websites where someone has done this to an xe?
You've got me thinking now guys......
Cheers

HI
Have a look at

The gsxr ones are tappered, mine are 48mm in, 42mm butterfly and 40mm out

I'm still waiting for my Megasquirt kit to turn up. I've already done one but sold it all, now I will build another and program it with
MS Extra for the Toyota. This will have cold start and other more desirable items in it!
I've searched on gixxer injectors and found the value as 95cc for the GSX-R600.
This is well down compared to the 4age car engine which has 200cc injectors. Most engines have an average around 250cc and are uprated for tuned
applications.
I've also found this blurb :-
Quote-----
"Peak torque is now listed as 3 percent stronger. This is achieved in part
by the use of a new fuel injection system, which is 370 grams lighter
than last year's. Where the 03 used four, single-barrel throttle bodies,
the 04's feature dual, double-barrel units with Suzuki Dual Throttle Valve
(SDTV). Containing two butterfly valves inside the throttle body, the
primary is controlled by the rider, the secondary by the bike's smaller,
lighter Electronic Control Module (ECM). Reading information from
sensors located on the crankshaft, the gearbox and the throttle, the
ECM uses a stepping motor. This opens and closes this secondary
butterfly, depending on the engine rpm, the gear position, or how much
throttle the rider is dialing in. The result is a feel that is similar to that of
CV carburetors, allowing the bike to pull strongly from as low as 6000
rpm. Pretty amazing when you think it revs to 15500 rpm!"
---------End quote
That explains the dual butterflies then

From searching the web a gsxr 750 can have anything from 120 to 141 bhp, i'm only hoping to get my pinto to 150 so i'm hoping mine are
from the more powerfull ones
As for your's Rob have you seen
http://venus.13x.com/roadracingworld/issues/apr00/gsxr.htm
Theres a good diagram of how the twin butterfies work

Bears out what I said on my original post regarding smooth transition when throttle opened, even mentioned accelerator pump enrichment.
I looked at the 'motor' and thought it must be current variable, I didn't see it as a stepper motor but a linear version of same.
I'm making up some ali blanking plugs to fill in the injector ports and the butterfly spindle holes.

Ive just won a set of gpz1100 throttle bodies on Ebay.I didnt know what bore they were but have just established that they are 34mm bore and fitted
with 180cc injectors. Any views on whether they will be ok on my lightly tuned 1600 crossflow?
They do seem to be very popular for bike conversions as they are easily split, the injectors are the same as nissan 200sx.

Does anyone no what other car injectors will fit the gsxr bodies?
Just been told on the sevens list that mine are likely to be 190cc, which is a bit small for 150+ bhp
I've been recommended 250cc+
Thanks Adrian

I believe Claire Rule on the BEC list ran her Crossflow on these 'bodies without any problems. IIRC, Nissan 200SX goes around 160ish BHP so you
should be fine.

I'm fitting Cossie Blue Injectors with Jenvey rail to my respaced Gixxer750 'bodies.
If you're not respacing then you can probably use the original fuel rail with these, but you'll need to alter the mounts to relocate the
rail for the injector inlets.

BTW I think the rough rule of thumb is divide by 5 then multiply by the number of cylinders to get the expect engine power.
190cc/5=38
38*4 =152bhp

Hi Steve
Found an sizing calc on the web, but that siad 125 bhp?
As for cossie blue's aren't they a bit big? my DT cat says their 437cc's
Also do they fit the bodies ok? I still have my old pinto injectors and their to big for the hole

I'm going by a rule of thumb that I know people use. I'm sure there's other, better, more scientific ways (which you calculator is
probably using) (bearing in mind divide by 5 multiply by cylinders doesn't take into account where in the rev range the peak power is.)
Light Blues are 400+ccs and are part of a stage 3/4 upgrade.
Dark Blues and Yellows are good for approx 200-250bhp. Think they're about 300cc.
WRT fitting, the blues fitted my GSXR750 rail/inlet holes without any issues (see pics on
Page 1). However, the seal is created by the rubber O-Ring. Different sizes of
o-ring may allow them to fit your bodies and rail without drama.

BTW I am not an expert on this...just relaying bits I've picked up over the last couple of years.
I'd definitely ask the same questions on the Megasquirt forums at http://www.msefi.com/. There's a number
of *real* experts there!
Good article on injector sizing here
Looks like you're right - you'll either need slightly bigger injectors for 150bhp, or run the fuel rail at a slightly higher pressure than
normal.

So long as you have a good seal then you should be OK.
