GSXR Thottle Bodies onto Toyota 4AGE?
Can someone please give me some straightforward advice?
What are the implications of fitting GSXR thottle bodies to my 4AGE. Ideally i would like to retain the original Toyota fuel rail and injectors. Is
that possible and what implications are there to the dreaded electronics? - thats what really scares me, being a mechanical type!!
Any help or advice greatly appreciated.

I was looking into this a while back now. I never did get anywhere with it though! I was hoping to do pretty much the same as you are, but perhaps
use a custom fuel rail. I was going to get round the electronics by junking the stock toyota FI etc, and fit a megasquirt unit instead....

Dammit! Too many decisions....

Hi,
Im using GSXR 750 bodies on my Honda engine, I have had some new spacers turned up, and am keeping the stock Honda fuel rail. I found that the
Honda injectors fit perfectly into the TB's so am using them. Not a 4AGE, but might be some help, if you want some pics let me know.

If you have any pics of the spacers you made up, that would be good to see!
Also, what diameter are the GSXR thottle bodies? (at the engine mount side specifically?)

I fitted GSXR 600 t/b's to my 4age. I used the standard fuel rail and toyota injectors (I think the later ones are about 315cc). This was fitted
to an ally manifold and ran on an omex 500 ecu. There are a couple of pics in my archive. The 600 t/b's are 42mm tapered to 38mm if I remember
correctly.

Andy, sorry its taken me a whikle to post these, but my camera was on loan, and the pics i took with my phone were to rubbish to post.
Old spacer on right, new one on left:
 
TB spacers
You also need to make a new angled bracket to hold the TB's together on the other side, and make an elongated threaded bar that goes through the
spacers. Old stuff at the top, new (unfinished) at the bottom.
 
TB bits
The TB's are 48mm on the intake side, tapering down to 40mm on the engine side (not including the injector notch). I would post more pics, but my
photo gallery is coming up with "You have an error in your SQL syntax... Blah Blah Blah" when I try and view any more pics  you should
be aware that diferent year GSXR 750's seem to have different TB's the ones I have are very modular, and easy to modify. I will post some
pics for you if i can work out whats going on with my gallery.

I'm just exploring fitting the GSXr T/B's to my 4AGE engine too. I have a few Questions though (idiot's guide if you like) as
I've not seen an installation first hand and I don't know anything about bikes!
1) Will they be suitable for a TVIS engine?
2) What's the best one to go for (600 v 750) or are other types better suited to this appliaction? I've had quotes of £100 for them, is
this about the right money?
3) What engine management system should I go for?
4)Does anyone have details of the manifold that I would need to manufacture (or details / drg's / dim's, that I could copy)? Or where can
I buy a ready made one from?
5)Can someone explain in a bit more detail what I should do with the injectors?
6) And lastly, will it be an easy job or should I just get some carb's, as time is rather short at present and I just wan't to get my car
on the road!
Cheers in advance for youe help!
Rich

Seriously rare in the UK and very expensive if you find one. I know Fensport sell them for about £1600.
I've lived a life that's full.
I've traveled each and ev'ry highway.
But more, much more than this,
I did it side-ah-ways.
