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.... ;)

Re: Question about turbo sizing on a bike.
 

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.

Re: Question about turbo sizing on a bike.
 

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

Re: Question about turbo sizing on a bike.
 

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

Re: Question about turbo sizing on a bike.
 

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.

Re: Question about turbo sizing on a bike.
 

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.

Attachment 15481
Attachment 15482
The intake manifold is made out of 16 gauge sheet aluminum and 16 gauge 2 inch aluminum pipe


Attachment 15483

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

Attachment 15484
This is the oil drain that will now have a pump inline to get the oil out of the turbo.

Attachment 15485
Attachment 15486
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.

Attachment 15487
I also had to drill a hole in my gas tank to make my bike a return style fuel system.

Attachment 15488
Attachment 15489
My aluminum piping is paired with some of CDM's finest BOV.

Attachment 15490
Attachment 15491
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

Attachment 15492
Attachment 15493
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

Re: My Turbo GSXR750 Project
 

I aprove :)


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

Re: My Turbo GSXR750 Project
 

is that a pic of one of the new f800 bmw's but odviasly turbo?
if so hows it run and you got numbers?
they make like 78hp stock



and back the the gsxr be ready to stop buying front tires because with boost on a 750 the front tire will never touch the ground
i have never rode one that was turbo but i rode a non turbo 750 and a turbo 600 and they were both rockets

Re: My Turbo GSXR750 Project
 

Thanks, and I am a tuner for eCtune so naturally I think that an FI setup is easier than a carburetter setup.

Re: My Turbo GSXR750 Project
 

explain to us why you want to turbo a 600/750cc bike when swapping a 1000cc engine in will be easier, lighter, and absolutely strap its ass.


turbo'd bikes are dangerous to sport ride. its almost impossible to get a good transition into boost at the 50-60% rpm range and retain any top end power. making for a very dangerous bike that comes on and off boost in the top 75% of the rpm range. first time you hit boost with a lean and you'll be thrown into a tree or a telephone pole.


i should know... ask my DOS buddy, non-scrub gear mind you, who threw himself into a telephone pole. that's why i refuse to work on bikes. it's NOT cost effective, it's still SLOWER and handles WORSE than jus swapping in a bigger engine.

Re: My Turbo GSXR750 Project
 

Swapping a liter engine in a gsxr 600 or 750 is easier? Lighter? No, fail on both accounts. I've put 750's in 600's and 1000's in 750. It's not at all "easy". ::)

"turbo'd bikes are dangerous to sport ride. its almost impossible to get a good transition into boost at the 50-60% rpm range and retain any top end power" ::) ::)

Hello, all bike are dangerous to some extent depending on the jackass operating them. And the turbo transition thing...How many turbo bikes have you ridden?

Your buddy that threw himself into a pole failed at riding, period. Slower and handles worst? ::) ::) ::)
FAIL FAIL FAIL

!000cc bike don't just "drop in" there is a lot of things that need to be swapped including but not limited to: Radiator, harness changes/modification (sometimes not always) ECU's (sometimes not always) Throttle bodies, cable re-routes ect. That ---- is not easy by any stretch of the imagination and there is ALWAYS fitment problems with about half the ----.

I disagree with you wholeheartedly sir.

Re: My Turbo GSXR750 Project
 

The only reasonable explanation it your question is that 10 lbs on a d seiers will turn you out, 7 pounds on a GSXR will turn you inside out.

It also dose not hurt that boost gives me a chubby.

I am also willing to bet that my shitty turbo'd 750 will put down more power that a 1000 of the same year GSXR.

None the less I will take your comments as constructive criticism and I am glad that you are concerned about me keeping my flesh intact.

Re: My Turbo GSXR750 Project
 

Not even in the neigborhood of close.

'97 Kawasaki ninja Zx-6R

103hp from the factory and I've never dynoed it on boost so I couldn't tell you (I'd guess 125whp @ 10lbs)

Re: My Turbo GSXR750 Project
 

That CBR was ------' clean man...I understand you wantin' to experience boost on a bike, but I have a feeling you'll eventually regret getting rid of that bike. I haven't seen one of those in that good of shape in a looooonnnngggg time.

Re: My Turbo GSXR750 Project
 

No way, You have no idea the difference that 150cc will make on a sport bike. Night and day difference. When I would wheelie the 600, if I did not clutch it up right I could not just give it more throttle and set the bike where I wanted it. With the new bike I can put that thing where ever I want and the power is on tap.

I just want the boost for 90-100MPH power wheelies.

Re: My Turbo GSXR750 Project
 

Oh Jesus, a ------- squid. :3

Re: My Turbo GSXR750 Project
 

By no means. I have ridden bikes since I was 4. My first bike was a Honda crf50. It was a 1980's clutchless three speed that my dad bought and rebuilt for me. The first time I rode it I ran straight int a neighbors fence. I have been racing/riding bikes ever since. I raced motocross for years and have always rode something on two wheels. This is my 5th street bike and I have yet to lay one down on pavement so I hope I would not fall under that category. You cant seriously say that you turbo'd your bike to keep it on 2 wheels. I mean why?

Re: My Turbo GSXR750 Project
 

Yes I can. I did not turbo m bike to be a ------- cager or a squid, I turboed it because enough people told me I couldn't do it just because they wouldn't know where to start and they thought they were hot ---- in the technical department.

If you've been riding as long as you say you have without a crash incident, then you are the universal exception to the laws of probability. Just remember, given a long enough time-line, everyone crashes eventually. There is no reason to push your luck and tempt fate.

Bottom line:

A.I turboed my bike as kind of as a "science project" more so than anything else.

B.Turbocharging is a pretty elaborate endeavor to be applied to a stunt-bike. I recommend you stay N/A, it would be cheaper and yield better results for that kind of riding.

C.I don't like to see or hear about people getting hurt/killed on bikes ever. Ass clowns that stunt in traffic/freeway conditions tend to make ALL riders look bad and eventually donate their flesh and organs to the pavement. Either way, natural selection comes into play.

Re: My Turbo GSXR750 Project
 

bikes-sweet turbo sweeter! i dont no much about ikes but i want one someday. i want a bike like smoke from biker boyz or the one that is own by the guy played by kid rock

oh, ok
this is why i thought it was an f800 bmw
http://www.balderston.net/F800SRed1.jpg (clicky on the linky)
because all i had to look at were the sig and avitar pics and all three look like the f800 (especially the avitar with the weird fairing they have and the conventional forks allong with not being able to see how menny ports are on the log manny(

Re: My Turbo GSXR750 Project
 

Right....'cause one's a parallel twin and the other is an inline four.

Re: My Turbo GSXR750 Project
 

A. I love science ;D

B. Yes I know, This has been a complete pain in my ass. This stupid log manifold was harder to build than the one I made for my civic( look at the "stole my gf camera" thread I did.) I am not really not trying to be a STUNTA... lol I am just addicted to anything that goes "pssst" and is remotely fast. I am just tinkering in my garage and messing with my bike. Thought you guy would like to see it so I posted up.

C. I have also been amazed at my luck epically as accident prone I am. I do not want to do 200MPH wheelies next to a mini van full of kids on I 24, or be an ass clown, or make you look bad. I am just hoping I dont get "selected" :X.

Re: My Turbo GSXR750 Project
 

Looks good to me brother. Boost on 2 wheels is the only way to fly.

BTW, you don't really need that oil scavenge pump if you keep it on the back tire. :y

Re: My Turbo GSXR750 Project
 

I would first like to thank MRMOCOS. He is a member of the forum here and sold me the BEGI FMU. I found a for sale thread on here that was old as hell and he had this FMU listed. I shot him a email and he called me the next day and said he still had it. I sent him the money via PAYPAL and expected it in the mail in the next couple of days. He (MRMOCOS) calls me back and says that he took it apart to make sure it was in working order. He found a broken spring and called me right back and said there was a problem. He offers me a full refund or says he will fix it and then ship it to me. He took the initiative to call BEGI and order the correct replacement parts and had them shipped to my house at no additional cost. Not only that, BEGI suggested if the spring was broke that there was probably some shim damage, so he paid for that to be shipped also. MRMOCOS is a stand up guy in my book and I will vouch for him any day. Thanks again man, it is people like you that make me think there is still hope for humanity and doing the right thing.

On to the bike, I just received the shims and spring for the BEGI and I also got the oil pump. I am going to work on it and hopefully do a little test riding if all goes well. Wish me luck!

Re: My Turbo GSXR750 Project
 

If this is your fisrt run on boost my only advice to you is to check you charge pipe connections. I lost a charge pipe in a wheelie the 5th or 6th run I ever did and nearly got killed. DOUBLE CHECK that ---- mang. :y

Re: My Turbo GSXR750 Project
 

Good to hear everything is going well. Will be following your progress. :8

Re: My Turbo GSXR750 Project
 

Ok, It has been a while since I updated this thread. It has been fun, but I have had some troubles. I went to the dyno and could not get the boost to go over 3psi. Also the gauge would flutter and not hold steady boost. I put down 160 hp on 3psi. I was not happy that I couldnt get the boost to go over that.

I did a ton of testing and could not get the flutter to go away. Long story short I ended up buying a different boost gauge and all the problems went away.

I also got to thinking my bike was not accelerating correctly. Ever since I owned the bike It just did not feel right. I mean if I was at 3000 and twisted the throttle the torque did not fell like it was there. My buddy rode it before I turbo'd it and he said something was wrong. I decided I wanted to check the motor out and just make sure everything was ok. I did a compression test and got 170-180 accross the boar(thats within the spec). I took my valve cover off to check the timing and my intake cam was retarded 1 tooth.

Basically I made 160 HP on 3 PSI with the engine timing off. This 1 tooth makes all the difference in the world. My bike revs much quicker and has the snap it should. I have bought a APE tensioner and it will be here in a couple of days to prevent any more problems with timing chain slippage.

More bad news is my turbo is leaking oil. It only does it sometimes and I have a return pump on it. I think I need to change the turbo to a ball bearing. See the BB turbos need little to no oil and you can restrict them down pretty good. I have talked to a turbo shop around here and because I am getting small traces of oil on both sides of the turbo, he thinks too much pressure is building up in the turbo and pushing past the seals. Tuff-guy, I am pm'ing you my number, I have a couple of questions and ideas and im hoping your personal experience will help me out some.

I am looking for a gt28r or a T28 off of a Nissan 240 Black Top(Its a T28 Ball bearing). I have a gt3076R in my garage but that turbo is way too big for a 750. Maybe a Busa, but not the 750

All in all I am still working out some bugs and I might take the kit off until I can get the exact turbo I want for the bike. By the way 2nd gear is a hand full.

Re: My Turbo GSXR750 Project
 

Gt28R on your setup is gonna WIN. I'll talk to you about it tomorrow, as we've (more people than just myself) have seen this problem before and I've got some insight for you.

Re: My Turbo GSXR750 Project
 

where the heck are the pictures?

Re: My Turbo GSXR750 Project
 

Pics are working fine for me. ???

Re: My Turbo GSXR750 Project
 

I rn a GT28R on my 686cc at, and seems to work quite well, spools very quick, just a tad on the lagy side, but you have more cc's it might be working better for you. I hae a stroker 861cc kit in my garage to be installed soon, I will have before and after dyno's if you are interested, but then again they are quite different with a single clinder vs. a 4 cylinder

Hi adam just a quick note do yourself a favour and just inspect the TPS (throttle position sensor) the Suzuki's have a habbet for chewing them up (I know I have had a few currently got a K9 750)

Its a precationery check and maby also avoid you the hassel later of chasing phantom faults

Its easy just take a volt meter place the positive on the center wire (sence feed ) the neg on the motor with ign switched on you should read from 2.2V to 4.8V as you open the throttle from closed to full open if the readings climb settdly unit is ok if readings are erractic or at times disappear unit is toast

The unit norm wears a groove in the slide plate so between 1/3 and 1/2 throttle the slide plate over times breakes contact with the resistor windings and the ecm get a false signal the ecm only knows if something is wrong when the signal feed is gone for more that 15s or if voltage is below 1v or above 4.8 but most sensor should report between 2-4.5v to the ecm when bike is running
