1100 turbo

[Vinny]

Hi Everyone , I'm Vinny and live in Devon, hope all is well , hoping someone out there will know the answer to this one... I have built and modified a few 750s over the years and built a draw though 1170 gpz b1, but wanted to do an 1100 a1 turbo ,as i love the low down grunt of the 1100 motor. I now have a bike, motor will be apart today , new pistons etc for turbo ,send crank of for balancing and welding , I always had motor work done by Ray Debben but sadly he's retired ,great loss to us all...but was wondering as i have a complete loom and all eletronitc's from a 750e can i use this on the 1100? keeping the 1100a1 DFI , I can't see why this would not work but not 100% . just think this will be a more reliable way of getting it to run right , MR Kawasaki done a great job with the standard set up , and leaves more money for motor work . I also have a 750e plenum and think this will fit without too much mods , or am i missing something?
all the best, Vinny

hI Vinny.

There are 2 looms on the bikes, one main loom and one for the fuel injection side.

It may be worth your while trying to find out the various part numbers and getting hold of the wiring diagrams. Theh you could compare them against each other.

The main difference will be the ECU as well as the obvious things like FPR, injectors, etc.

Hi, thanks for that, the plan is to put all the electrics from the 750e inc ecu etc on the 1100a, so no 1100 loom used , so using the 750e boost sensor and plenum in my mind will work? hopefully anyway... going for it as i have all the parts .. will let you know if it works ..was just wondering if it had been done.. what's the worst that can happen? as long as it runs and boost sensor retards the ignition i'm on to a winner ..

Definitely interested in this project . Please keep us posted .

Bet this would work. Thinking of the E1/2 setup if you use everything you may have to just use a larger injector for the 1100. If the computer will give the 1100 good manner ie timing etc. which it really should with turbo timing is very similar in engines. The stock injectors at 240cc are way to small for 1100 turbo'd so you may have to run about a 360cc low impedance injector. Might be larger. I ran on my 810 some 36lb L I injectors and the engine had other mods and bigger turbo. It ran incredible up to about 3/4 throttle then just after that could not handle the fuel from the 36lbers. I also had to lower the pressure from 43 with stockers to 34lb with 360s. Went to 300s with 41 lbs. Just some useless info lol

cool, every bit of info helps.. looking at 440 cc injectors? may have to contact Lorcan as he's the man for this.. Dave Donlop (fast by me turbo's) has just completed a full kit for the kz 1000-1100 .. picking it up next week ..look's superb ..he's running carbs but I want to go EFI ..
waiting for MTC big block from Nick Pepper (1327cc) Chris Applebee has the crank so all coming together .. will post picks when I have worth while ones ..

and boost sensor retards the ignition i'm on to a winner ..

The turbo ecu only does fuel, the ignition has a stand alone ignitor, which has an output trigger wire for the fuel ecu. It has less advance built into the curve than a na one, but with a bit of parts swapping you may be able to get it to work on the 1100.
You'll no doubt have to run a power commander, I can't see the fuel curves being anywhere near the same, and you'll want to open up the intake into the plenum for the 1100 too.
Not wanting to seem like I'm rubbishing your idea, but you could probably sell the turbo ecu for good money, and just run an aftermarket ecu with the $$$ from that and what you'll save from not buying a power commander etc. Then you can incorporate the ignition timing into it too.

Thanks bud, just experimenting with it tbh. have weld the plenum up, as you said its too small, if this gets to complicated i will get dyna 2000 and bang a set of carbs on it ...had no probs with my last 1170 turbo set up like this ...cheers

Hi Vinny,

Welcome to the forum. Let us know how it's going. A PC and turbo ECU would be the way to go IMO, maybe with a base spacer to lower the compression and some milder cams. It can be done with blow through carbs but I kinda like the "factory" setup. It would be an authentic period setup, not a workaround, if that makes sense.

Hi Lorcan, thanks for that, sorry for late reply ,hope all is well? i've been hitting it hard to get it done.. motor's now built .. 1327 low comp billet block (should be fun) spent far to much on it already ..had a few bits made by a mutual mate.. Tony Kershaw ..he say's Hi.. I.m being stubborn and despite the hassle want to keep the look of the motor and DFI .. if you have any old parts for sale or advice that helps i would be very grateful ..think i can sort most parts out but stuck on injectors? everyone keeps telling me to put carbs on it...that's last resort ..
will upload some pics soon...cheers, Vinny

[georgew4714]

Probably the same people that are more familiar with carbs over injectors . People comfortable with injection will tell you the opposite .

[Charlie @ Evergreen]

If your running only the stock turbo ECU you have to use low impedance injectors. With 1327 gonna need some good size injectors. Not sure about what size with a 1327. Lorcan's mention of the stock ECU & Power Commander is likely the best way to go. Remember with a PC those are high impedance injectors so you may need a H.I. Injector that might be more in the 600 to 700cc range. Tune with the PC. Sure Lorcn will chime in soon. Good luck!

thank you everyone ... slowly wining..

Hi.. just made a nice donation ... need to keep this site going .. have to talk to the wife otherwise ...
Cheers , Vinny

Hey Vinny, how is this going? Sorry I don't get here more often, I have other interests! Many of my ancestors lived in the Dartmouth area, specifically Dartington. Maybe we are brothers from another mother?

I remember Tony Kershaw from UltStreet days, but if I spoke with him it was a VERY long time ago! Send me regards please. Also let me know the email your donation came from so I can upgrade your account to supporter status. Cheers!
