My friend is looking to power up his G13B in a Mini and he would like to go ITB way!
My question is, are there any "of the shelf" ITBs for G13B?
Megasquirt woud be ECU
Tnx

No, is the answer.
I have Yamaha R1 carbs on mine. My friend tried with Honda CBR1000 carbs and it works well.
I think many of them are non equal spacing but I managed to space them out easy enough. So R1 ITBs might work OK. If you want inlet flange let me know as I have one already made. I have one starting make with Kawasaki ITBs.
Do you want to see a photo?
I have to dig out my shed somewhere!

Cheers

Thanks for your answer Atchi I was hoping for it cause you're deff a guru of G13B!
Maybe you could help me as my friend is full of wishes but I'm not that familiar with Suzuki...
He would like to fit ITB (it has to be of a bike and custom made intake as it appears), megasquirt (don't know what I need for it), 4-2-1 manifold, AL radiator(standard Mini size one), LSD (or some other diff that reduces torque steer)...
Can you point me in some directions?
Tnx

I have a spare mk2 Gti LSD diff.

I shall dig out few bits and bobs to show you.
MS uses Bosch TPS, I think and BMW K100 uses TPS. So it might work if you use K100 setup?

Cheers

Thanks for offers guys but I think he will go for this option

http://www.ebay.co.uk/itm/Suzuki-Swi...m-STARTER-PACK

as it's closest to of the shelf package...

But there are all that other thing that he need...
LSD, header, AL rad, MS parts as he now have MS1 V2.2 and I don't know what he needs to install it...

He'll need to modify either the bulkhead or the inlet manifold if he wants to fit that kit in. I have very, very similar setup on my g13b with MS and gsxr600 itbs.

Thanks for input Purtsi!
I did contact them and asked if it's possible to make intake so that TBs can be angled...I went through your build and noticed the problem
On the other hand maybe you could point me out for some FD and LSD components...where to look and what is best for 13" wheels?

I got my LSD specially made in Hungary for my mk1 'box. I can check the contact name from my emails. He can do LSDs for later 'boxes too.

I don't know what's best for 13" wheels as I decided to run on 10s =P

That would be great thanx!
As for FD we decided to go with 1.3 GS gearbox, the fastest gearbox-recommended for long high-way cruise with FD ratio 21 x 74 (3,523:1)...
The diff in GS GB is the only "weaker" part compared to GTI gearbox, changing it to LSD we'll avoid any "weak" spots.

I was contacted yesterday evening from danst engineering and I was told that the manifold they make is normally angled 20degs upwards but that they can adjust it if needed...
I'm not sure what angle to look for now because engine is no longer in the car...any suggestion would be nice or even some measures as guidelines

Szarvas Balázs (szarvas at gmail.com) is the guy who makes the LSDs. you can find several threads about his work in redlinegti.com and teamswift.net forums.

If I remember correctly, I have 30deg angle on my manifold but it all depends on what angle engine is fitted etc. Also if the manifold is quite tall, the filter might hit the bonnet as in my case. Also if you use standard fuel rail, you need to make sure the manifold won't hit that.

Hi,
You want to take out input shaft and crown wheel off GS gearbox and fit it into your Gti gearbox. Gti gearbox is close ratio 3-5th gears so you will keep in torque band each time you change gears. it is very easy to do. I thought 3.78:1 from G13A gearbox will be better which I have for my 13" wheeled car.

Cheers
Atchi

I think I have a 10mm Ali inlet flange and some triumph inlets rubbers bolted together that I won't be using. The idea was to put some steel/Ali tube bends and then silicone connectors to the ITBs for my set up.

I've since gone for a custom welded manifold so I no longer need it.

I'll have to dig it out if you're interested and haven't bought anything else
