My Turbo GSXR750 Project
 

I currently have a cbr600f4(not fuel injected) and I am wanting to go turbo. I do not want to try to turbo this bike because of the lack of fuel injection. I am about to pick up some sort of a fuel injected 600 or 750. Does anyone have a clue if a 14b is too big? I am going to put an external wastegate and only run 5 psi. All the intake an turbo manifold will be fabricated by me so I am doing this build on the cheap!!! I am just looking for a little insight, Thanks

P.S. If anyone knows of an open source for bike fuel injection I would appreciate a link or a suggestion in the right direction. Most guys are running a fmu and maybe a power commander. IMO the power commander is just like a afc and is bullshit so I am trying to find something more advanced.

Ninja Edit:

I am just turning this therad into my build thread. Scroll down a couple of post and you will see the progress.

Thanks and enjoy

good work, have fun tuning it.... ;)

Dude, WTF? I click on this thread and hope someone with a little insight has shed a bit of light on my question and all I get is a stupid response from you, For your information when you talk about bikes it is not called megasquirt, It is microsquirt. Now who is the dumb ass? :1 You do not think I knew about that option already? I was looking for something not so baller, this is HMT and almost 500 dollars for a fuel management system is a little more than I am wanting to spend considering that my whole turbo kit will cost under 500.

I have forgotten more about fuel injection than you will ever know and please feel free to never comment on one of my threads again.

Were using a ebay t25 on a microsquirt tuned Bandit. so I would say go with the 14 or a t25 turbo

TD04HL would be pretty sweet too. There's one for sale in the classifieds now.

Wicked turbo's those! What size compressor Wheel will be appropraite?

Re: Question about turbo sizing on a bike.
 

I was talking about a 13g, but of course they come with T-series compressor wheels and I'm pretty sure B-series as well.

OP, have you considered a TC05-12a off a Starion? IDK if the 5cm hotside will be big enough if you want to rev out, so a 12a may be a good solution. It has a 6cm housing like a 14b, but a smaller turbine/compressor and would probably be well sized. They can make 275hp maxed out, but are in their efficiency range from roughly 155hp-240>hp. IDK what your goals are, but the 12a or 13g would be a great selection out of the almost limitless possibilities. Their price makes them attractive for sure.

Thanks for the replies, A little update:
I sold the CBR in 1 hour on craigslist to a :8 . I then found a 2003 GSXR600 that was said to be in good condition. I drove to Missouri to buy the bike from the guy and it was not even the same bike that he had pictured on the add. So I drove home and I found a 2001 GSXR750 about 15 miles from my house. Picked it up, went on vacation to Texas, and rode the piss out of it. Got back home and tore it apart.

I have started the project and have all the fabrication done. I decided to go with the stock turbo off a automatic Mitsubishi eclipse. I just tried to start it today and I am having problems with my oil return being too low so I am purchasing scavenge pump. I will update this thread with pics when I got over to the shop to work on it again.

Re: Question about turbo sizing on a bike.
 

Here is the progress as of today. I ordered the pump and it should be here in the middle of next week. I have some connects with a motorcycle shop here in town and I will be dyno tuning it hopefully in the next two weeks. This is all dependent on if I run into any more problems.

Now on to the pics:

This was the bike I originally had, I really hated to see it go because it was so clean.

The intake manifold is made out of 16 gauge sheet aluminum and 16 gauge 2 inch aluminum pipe

The turbo manifold is made out of 2 1.5 inch stainless tees and 2 1.5 inch elbows. These were purchased from weir. I also had to weld the stock header pieces inside the 1.5 pipe so it could bolt to the head. This looks really simple to make but it has been an extremely huge pain in my ass. The placement of these runners is extremely important and every time I would weld on it some it would change the position of them. Needless to say I have cut and welded this maniflold several times :7

This is the oil drain that will now have a pump inline to get the oil out of the turbo.

This is a walbro 255 inline pump, I have gutted the stock fuel pump and have installed the brackets back in the tank so that I do not have a low fuel light on all the time. I will be switching the FMU in the pictures for a BEGI fmu I purchased from a member on here(if I ever get the replacement spring and shims in the mail). The BEGI FMU is adjustable so I can "fine tune" the bike a little more. You also like my temporary fuel tank for testing purposes dont ya.

I also had to drill a hole in my gas tank to make my bike a return style fuel system.

My aluminum piping is paired with some of CDM's finest BOV.

This is the computer I will be using on the bike. It is basically the same as a power commander but it can also adjust timing. Because the tuning world is a couple of years behind on bikes, most turbo kits just use the FMU to controll to fuel under boost and you use the Yoshi box to control fuel in part throttle and to make ignition adjustments. These motors are 12 to 1 compression but you do not have to retard timing until you want to go over 7 or 8 psi

I will be putting the fairings on when I finish her up but I will have to cut them for exhaust and airfilter.

Thats all I got today folks. Hope you enjoyed

I aprove :)


On a side note, boosting a carbed bike is actually easier than an EFI bike. ;)
