    IN!

    Unfortunately, I recently saw a picture of a suck-through turbo running a FCR-MX carb. I thought "hey, that looks really simple to fabricate". Just starting up the steep part of the learning curve on turbos.

    Good to hear I am exactly in the same boat as you looking to gather information on this subject, it appears we might be in a very small minority.

    Corky Bell wrote a great book on turbocharging the proper way and is a great resource for getting a system together. From there It's heat management and placement of everything so that it all fits.

    If you're considering a build, apart from above mentioned book (Hugh McGinnis had a very good volume as well, covered turbocharging just about anything but somewhat dated now) then there are some good resources online. RB Racing sells kits for Harleys and BMW twins (strange bed fellows) plus have a lot of info if you can sift through the angst. "750turbo.com" is where the Kawasaki guys hang out - some very impressive HP numbers and nice looking stock (or not so much) bikes. The MS forums have a large following of guys "doing it" and there are examples of turboing/ fuel injecting any and all machines there to learn on etc.
    Do your homework before you start spending $$ on parts (or not). A review of your engine specs, with performance maps for the turbo being considered is a must. Otherwise you're pretty much like a leaf at the mercy of the wind (or something into the wind)- and the neverending moaning/ groaning about turbo systems that "just don't perform well" or "are too laggy/ take miles to spool up" etc. may be your experience. I don't recomend blow through systems - simply because there is so much more possible with fuel injection, and in fact full electronic control of every aspect of ignition and fueling. As perhaps suspected, I am a "Megasquirter", using the smaller fully programable "MicroSquirt" on my projects.
    Current daily runner: 1983 BMW R100RT

    All hand built except for the throttle body off a Honda CTX650, and the small center "Y" portion of the exhaust manifold, otherwise assembled from parts.
    DSC02266.JPG
    Above depicts the intake system. Compressor off the smallish Mitsubishi enter charge air cooler, runs up past blow off valve into buffer chamber and throttle body. Splits off to both sides for gentle curve back to inlet ports on the boxer airhead engine. Up top are water/ meth injectors (most recently relocated down adacent to injectors which spray directly onto inlet valves heads).
    DSC02262.JPG
    Exhaust side of things. Keep in mind this all has to fit within the confines of a fully faired RT (some hate, I love) making it something of a "sleeper" to other unsuspecting (and grossly noisy - need I say more) road mates. I used 321 stainless throughout (best to avoid intergranular corrosion unless you are going to use heavy cast pieces). The turbine exits along the left side running back to a "Y" where I've hidden a "Divertor valve" that is linkage controled "gear shift" fashion by your right side foot. Down provides a clean exit off the turbine for more distinct "turbo" while up sends the flow to the right side muffler alone (much quieter and gentlemanly like and actually not significantly different performance wise). They said "tricks are for kids, not rabbits", wasn't paying attention.
    photo 4.jpg
    The Microsquirt ECU resides back safely under the seat at a rear little compartment. Tuning on these has become significantly easier with many aides and autotune programs on that. Most will be turned off by the mere mention of a computer, I"m no expert, actually rather old school in my training but find it rather simple. I wouldn't go back to carbs, points, etc. for anything.

    Up next, got a nice little BMW K75 coming together, its already fuel injected but I'll be using another Microsquirt, and Turbo of course. Not much to show yet, I did create and install an "opposite side stand" which goes off the right side of the K, rather than stock left side which drains oil back into the cylinders and causes something of an oil clouds at most start ups (rather entertaining and I feel un-necessary).
    Cheers and as you say, probably rather a limited number of participants here.

    Marauder T-1.jpg Marauder T-2.jpg When time allows, I'm working on a '98 Suzuki VZ-800 Marauder Turbo. The turbo unit is a K03 with stock cams/ignition and a custom set of Ross pistons, lowering compression ratio from 11:1 down to 8.25:1.
    Pictures show an early part of the build and the turbo outlet has been slightly repositioned today. I plan to use a blow-through system and no muffler but we'll see. I think there'll be enough length of pipe/twists & turns that will effectively knock down any obnoxious noise (will add baffles if needed though I'm intuitively thinking none will be needed - we'll see)

    The exhaust is being built in the pictures but I've finished one iteration and now will redo and simplify.

    As a megasquirter, I would love to tap you for some resources. I have a microsquirt which I (very optimistically) purchased for a NA project. I understand the theory of how to build a F/A map from scratch, but the ignition map eludes me.

    Tap away, I've got no end of time to chat about squirting, settings, and off beat methods. Older V2 or V3 version on your MS?
    And where are my manners, nice work there jays100 & jimroid!

    Again this is the position i am in, interested but have no plans just yet.
    Thank you for the info and pics , and i read with interest on the mega squirt conversions, this brings with it not only performance potential even in NA applications but as part of a turbo build.
    I suppose corkys book and searching the internet and learning the basics thoroughly enough to start putting together a plan is the first step.
    Keep the information coming please, talking of such info. Mega Squirt?
    Can this be done on the cheap? From what little i know on it i understood it was programmable fi system utilising readily available ford components to some extent. What is the cheapest route to this FI system. ?

    I think ignition advance is fairly straightforward, in that with lots of boost, limit to 10 deg,...or advance just below detonation/ping at full boost on the fuel you’re moving. Microsquirt works for that.

    Ironically e85 gasoline works well with high boost/advance without detonation, much more forgiving.

    Interesting thread i suppose and it caught my eye as an ex Spondon GSX Turbo builder (17 yrs ownership) and now this Bandit Carbyturbo bike that i need to sell on really as my other projects need priority. I was going to build a steel lattice wrap around frame for it and incorporate the Co-axial swingarm pivot feature that my old Spony had but good old Father Time is chewing my balls off again..!! Errr, Matty old bean, you wouldn't be looking for a project yourself to take on by utter chance...??? The bike is down in Newcastle..... IMG_7940.JPG IMG_7937.JPG

    To be honest i would love to take on just such a project, but sadly my financial state kids going to university this year house rebuild and development to raise cash for the retirement in a decade or so, money is tight right now.
    But if i sell some other stuff off and get a bit of cash i think i can spare i will be in touch , but dont hold your breath the way things are right now.
    I am interested in perhaps doing a build at some point though but will be currently owned bikes on a low budget, i have a Honda CB1000 f that was a spares bike for my old CB1000 and a Triumph 900 that i thought might be candidates but just mulling over the info i can gain on the technology involved at the moment.

    Mega Squirt and smaller MicroSquirt are gaining notoriety for being the affordable approach to full on control of your hotrod, while offering best options, functionality, and support. There are a number of alternate systems out there, some are pretty basic and questionable.
    Nothing's free these days but you can assemble your own (soldering pencil, large magnifying glass, less $), I choose the cased MS kit which is just below $400.00us. For other items I like to challenge myself by searching wrecking yards and reuse of components, so many of the sensors etc are a small cost aspect. A wide band O2 system is a must for tuning the performance being made possible by turbocharging, but as with a "NA" project even just knowing fuel states, & there are many systems now available (some of the innovate wasn't really reliable). "14Point7" product has gained a lot of acceptance and about $200us gets you up to speed there.
    I am in about the same position as you Matty when it comes to home/ garden/ kids in University/ retirement/ etc. I fund my bike work by creating a bike fund through project work for friends, this and that, recently to my surprise and utter astonishment - approval from the "home team" for Christmas and birthday gifts - cash :lol2.
    I do fine tuning via real time logging and review on "MegaLog Viewer" which will run a simulation off the log and upgrade/ readjust settings to bring your tune into line. You can also do this while in real time, more challenging on a bike than cars etc. I have a mount for my lap top over the fuel tank (:fpalm) and utilize quiet country roads although you can log with a lap top in back pack, or utilize other smaller tablet devices, even connect to your I phone.
    Setting up an ignition map isn't that intimidating with TS, an auto-generator takes your engine specs and settings and fills the bins. I like to review the engines original settings and advance behaviour (pretty simplistic with many engines like the old BMW utilizing a flyweight versus spring plate to offer a pretty linear advance between two rpm's). There are other online files (oft times Xcel) that will further review numbers based on levels of boost, and ultimately you can choose each and every zone "judicially" to protect your engine from det. MS supports detonation retard control (I don't use).
    My favorite add on is "water/meth" injection which is a nice reliable method to up the timing anti while protecting your baby. Not the large "Jacuzzi" pumps but miniature stuff and proper flow levels for our smaller engines (in the above bike image, that rear passenger upright seat is also a 4 liter reservoir for the system).
    Ultimately, I don't wish to pollute your thread with too much MS tech stuff - if concensus states :snore, then PM's are fine to carry on with finer detail.
    Work beckons.

    Great post Thank you very much for penning this for inclusion here and dont for one second imagine its polluting this thread at all , quite the contrary in fact its exactly the kind of relevant info those of us contemplating turbo projects can benefit from.
    On the subject of turbos themselves , and choice of turbo variable vane turbos like on some hp diesel cars will they work on small petrol engines,? And the control ECU from say a diesel car be utilised or is the electronics aspect way too ambitious for home grown back yard built turbo projects. ?

    The variable geometry vaned turbos seem to becoming ever more prolific and reliable - I haven't had the funds/ inclination/ or time to venture down that pathway, but others with MS have. We have CAN control available (even on the microsquirt), and with MS3 source code the broadcast is ready to roll. The number of things you can control with even the Microsquirt is broad, including tranny control, traction control, blow off, nitrous, water/meth, multi fuel, etc.
    Not sure if you were implying "utilize the ECU from a diesel car?" - different kettle of fish then.

    I was more enquiring if the diesel turbo units were of use to us motorcyclists, and how to control these turbos i had no idea if the diesel ECUs were of use and or could be practically adapted someway.

    My turbo above is variable nozzle. The nozzle actuator was controlled with vacuum originally. I added a seal to the actuator, and moved the vacuum line on opposite side of diaphram so it worked off of boost. Turbo was from a diesel car originally.

    I think (& this is my personal opinion) that retasking any given ECU that has its application locked towards a particular engine ( basically any retail common brand product) towards another different engine or spec is an exercise in futility. This comes up when parts and an ECU are borrowed from one machine and then bolted onto an entirely different one - with a hope it will work. Even swapping settings onto someone's project from your "somewhat similar one" is ill advised for reasons of proper behaviour on programable kits.
    There are sniffing devices like "Kess" to suss out what lies hidden within an ECU but when you have the ability to systematically develop a proper tune with MS for example, that won't thrash your project, then that should be the chosen pathway.
    All opinions.
    Good response so far - let's see more bikes
