Let´s try again: Hi all! I´ve been here before, I had a 1100 blower/efi build, but I never finished it But now I´m back with a turboGSXR I traded for my Yamaha/Buell bastard. Heres the bike when I got it: I haven´t ridden a turbo bike for a while, so at first I thought the bike was a real rocket. But then after riding two other turboGSXRs, I was certain that something was missing, like 100hp... The bike started and ran nice but there was not enough power. I got the bike as project anyway, so after a few weeks of riding I took it apart. The exhaust header was leaking, the other wastegate was about to drop. I decided to build a new one, to get more space to relocate the wastegate. I´m planing on using just one gate, the outlet pipe welded to the housing. Here´s the old: And heres the new, still unfinished. J

I´m also going to change the looks of the bike , so I bought an other frame to use while trying different tails... I had a FZ1 swing arm lying around, so I modified it to fit in the GSXR frame. Heres some other versions I´ve tried:

The wiring also needs some work: Efi and engine management need a lot of wiring, but maybe there is something that can be done... A buddy of mine is an electrician, so I´m sure he can make it happen. J

At first I had some trouble finding a place for the waste gate. There was no room behind the front wheel: I wanted the exhaust gases to have a best possible way out, no 90deg angles etc. So here is what I came up with: I´m going to use one wastegate instead of two, so I need to divide the pipe.

I cut two holes in the exhaust housing, first drilled a hole, then used plasma cutter. Then I split the bend and welded a wall between the two halfs. I heated the housing and welded the bend with tig welder. Now I need to fit the housing back to the bike and find an exact place for the wastegate.

Cleaver stuff mate, just spent 2 hours changing an exhaust and must have used 3 million swear words , I admire patience and ingenuity

I'm trying to work out the pipe diameter based on a guess of the headers being 38mm? - it looks small, 25-30mm ID? That may give boost creep - something like a 38mm Tial is sort of getting to be the std norm baseline gate. A twin scroll is gonna be moving some gas when on boost!

Gsx, no ingenuity here, just plain copying (ok maybe I adapted a little ) Katana, its 42 outside, 38 inside, with Tial 38 gate. I hope thats enough. Tatech ecu is going to control the boost also. J

Here´s a few pics of the exhaust manifold, still looks like s**t. I´m going to coat it with Black Satin to fight the corrosion.. I also tried those tails again with the FZ swingarm.. J

The project is taking small steps: I ceramic goated The exhaust header and the turbo exhaust housing with Black Satin. I also got a new swing arm after butchering the FZ1 arm. I friend of mine machined the extensions and I welded them on. Yet another mock up. The swingarm is loooong... too long? I´ll just have to figure out the tail J

Like what you are doing with the build, arm does look long. ok for drag racing move wheel to forward of arm slot for road handling. Looks good though .
