Fuel injected turbo

[ice77]

I know I dont frequent this site all that often, but I  just thought I'd let you guys know that I have now successfully fuel injected and turbo charged my 1991 GS 500E.

I have use two throttle bodies from a Kwaka GPZ750, Haltech ECU, IHI turbo,  a heap of one off home made stuff and the odd car part.

Here's a link to some of the details  http://www.streetfighters.com.au/forum/topic.asp?TOPIC_ID=4463


You may ask why.    Because I could

Have you overheated your front tire yet?

Are you seriously turbocharging a 90k mile GS?  Keep the boost...uh...low.  I don't mean to poo-poo, it actually looks pretty fun!

It also looks as if you are going to boil your front tire.

The turbo has an internal waste gate, but I will have to change the actuator to open it earlier. I'm running between 7 to 8 psi, which is twice what I actually wanted . I didn't reallly build it for reliability, I was just trying to prove a point.  Blowing it up is probably inevidable.  I also have a 97 RF 900R, the GS will never be a match for it, but it's still good fun.

I took it to the April Fools Run last weekend, which is the biggest streetfighter get together in Australia. Picked up two trophys for my efforts, Most Progress on a Built since last AFR, and Best shed built Streetfighter. I was pretty happy with that.

I saw your video on youtube yesterday and was hoping you'd post on this forum soon.  Great work.

nice work ice. 

what ihi snail is that - td08?  if it is or is similar size - it looks like a good size on the gs.  funny, the td08 is the stock one that comes in my car (ver7 wrx) and it looks tiny in it.  but it isn't laggy and pushes 17/18 pounds just fine    the boost your running should be plenty for the gs.

looking forward to hearing more about it (either here or in your original thread) and congrats again with your work man.

Wish I coul;d see it in the flesh.

Fuel injection is something that could actually be sold for used bikes, and breath life into NEW bike sales for GS's.

C'mon

[bubba zanetti]

Ok now for the $64 question, whats it like on the road?

[Kasumi]

Faster than a standard GS 

[bubba zanetti]

Thanks, thats what I was wondering 

[Jay_wolf]

That Is A Fine Lookin Gs . One Thing , Crash Bars Look Soo Silly , Looks Like The Oz best Streetfightered Gs Is In His Hands.,. Hopefully illl Build The Uk's

[backd00r]

that's great ice - my mates and I have been debating which turbo you used.  your awards were well earned.

bd.

[ice77]

The turbo is a IHI RHF3, it's an after market add on for small capacity cars.

Hi, icebaby.

Awesome job on the bike. I am thoroughly impressed - i.e. f%$king cool!

I have a series of questions about the fuel injection part, and hope you find time to answer them.

what kind of controller did you use on the EFI?

did you tune the engine in a dyno cell, or just on a roller?

finally, did the GPZ throttle bodies just bolt up in place of the stock GSers or did you have to modify them, or the GS head?

what size injectors did you use?

what kind of fuel pump did you use, and did you build it into the fuel tank?

Thanks for your time.
Check out my other thread on a BCM. The reason I ask about the controller, is because I'm wondering if it has CAN capability. If it's megasquirt, awesome.

ECU is a Haltech F9. We had a basic map to work with, just modified it to suit.

To tune it we strapped a laptop to the fuel tank and rode it up and down the road in front of my mates place for about three days, adjusting it accordingly between each run. It's still not perfect but I had a deadline to meet so it was a case of near enough is good enough.

The GPZ throttle bodies are running standard 750 injectors,(not sure of the size). Luckily they fitted into the rubbers which join the GS carbies to the head. I had to change the spacing of the throttle bodies to match the head spacing, this was not a complex operation but there was quite afew fiddly little brackets, spacers and linkages.

The fuel pump is a Fuelmiser FPE-240 electric fuel pump. It's an after market external pump for a car and rather bulky around 160mm (6 1/2inch) long and 62.5mm (2 1/2 inch) in diameter.

Hope this helps.
