Turbocharging the fzr1000 (carb ????)

Turbocharging the fzr1000 Guys have any body turbocharged this bikes? I have a 87 fzr 1000 and was wondering if the carbs on this will work as a blow throw setup or will I have to make a custom carb box for them? Thanks Tim

I have (and still am trying) to perfect a turbo conversion on my '89 exup You will need to make sure that any opening on the carbs that used to 'see' ambient air pressure also see boost pressure by connecting them to the plenum chamber. Next you will need a high pressure fuel pump and a boost referenced fuel presure regulator to make sure that fuel pressure is always 2 to 3 psi above bosst pressure. Make up a zorst manifold to fit the turbo in somwhere and connect it all up. It is actually a heap more work than I've just described but is possible. <img src="http://img4.photobucket.com/albums/0703 ...  <img src="http://img4.photobucket.com/albums/0703 ...

If there's anyone that knows FZR turbo converts, TURBO you are the man. If anyone ever wants to do the same, I'll recomend them to you all the time. One day we'll have to get together and I can see the insanity that I'm glad not temted by everyday. I would love to see you completely toast the majority of bikes you come against. How do you keep your liscence? CHUCK D.

<a href="http://www.turbo-bike.net/">www.turbo-b ...  Loads of new info here. Keeping my licence is easy <img src=http://www.ezboard.com/images/emoticons/happy.gif ALT=":D"> The damn thing is in pieces most of the time leaving me invisible to police radar. I'm making up a new 4 into 1 manifold for the turbo at the moment to try and increase top end power and have chopped up my old log style one because it was crap gas flow wise. It's a real bitch keeping the turbo high enough to let the oil drain back into the sump and make a half decent flowing manifold. Then it's time to finaly sort the cam timing using the info on the above link. 200rwhp this year ???? Fingers crossed. Mark

Ok now for the questions. What did you use for the fuel pump and a boost referenced fuel pressure regulator? The most boost I would really want to run is 9psi. And all ways on 114 race gas. And is 150hp out of the stock motor resanble? I do no a little about turbo charging. I built a nice twin setup for a mustang and after that the bike really ant much faster. 10.70 @ 128mph 9psi street trim. And I love the way the power comes on. Thanks Tim

I'm using a turbo carb fuel pump from here <a href="http://www.merlinmotorsport.co.uk/">www ...  and a Lotus Esprit turbo fuel pressure regulator from the same place, they are made by malpassi and ideal because the lotus blows thru a pair of dellorto carbs. the biggest problem is keeping the turbo high enough to allow the oil to drain back into the sump and have a half decent flowing exhaust manifold. There is hardly any space to fit it all in and I had to move my oil filter to give room for the turbo. I would have thought 150bhp would be pretty easy on a stock motor. 10.7@128mph <img src=http://www.ezboard.com/images/emoticons/eek.gif ALT=":eek"> <img src=http://www.ezboard.com/images/emoticons/eek.gif ALT=":eek"> <img src=http://www.ezboard.com/images/emoticons/eek.gif ALT=":eek"> You need some serious horspower to move a car that fast, did you get your mustang on a dyno? Got to be 500 minumum I would have thought. Mark

Were did you happen to tap into the motor for the drain back? Also what kinda turbo did you use. Is there any junk yard turbos that would work? As for my car. No dyno numbers but going by the trap speeds it should of been very close to 500rwhp. Its just crazy the amount of power you can make with hardly no money. Go cheak out www.turbomustangs.com Theres all kinda guys with total stock engines that have dyno over 500hp. My engine wasnt nearly stock but my turbos are very close to be maxet out. (to turbocoupe turbos) .60 .63 Thanks for your help

I'm using an IHI RHB52 American part no 5T503 (if my memory is correct) it's been fitted with a bigger compressor wheel as suggested by a chap running a ZZR1100 motor at 300bhp using the same spec. I got the part no. from this book <a href="http://www.amazon.com/exec/obidos/tg/de ...  I am getting problems with overboost and have got to port the waste gate to try and get the gases out quicker along with making a new 4 into 1 ex manifold to replace my first log style one which flows crap. (stuck at 170RWHP) My oil return feed goes into the bottom of the sump which is not ideal but I don't have any trouble with smoking or burning oil so it must be OK. Don't you need forged pistons and steel rods to cope with 500bhp from a smallblock Ford or is yours a Cleavland motor rather than the Windsor Mark

boosted357 · Post by **boosted357** » Fri Feb 06, 2004 5:45 pm

When you mean your oil return feed goes into the bottom of the sump you mean the oil pan right? Do you happen to no any thing about the Vince hence ingtion for these bikes? The stock 86-92 mustang 5.0 came with factory forged pistons. Some people have good luck with stock parts and some don’t. It really just matters about the tune if the stock parts will live or not. They say the stock block will brake before a rod or crank will. I was useing a stock 100k mile short block.

As far as I know you can not get anything to alter ignition timing as the setup is different to a lot of bikes with the crank position sensor being mounted directly into the case picking up the timing signal from a slot machined in the crank. With Suzukis and Hondas I think they used a pressed piece of steel mounted on the end of the crank to to give the signal and this is the part they change to get different advance. I'm using stock igniter with dyna coils. One more expensive option would be to use this <a href="http://www.emeraldm3d.com/">www.emerald ...  I'm running it on my car and it is a very flexible system allowing up to 8 injectors on a 4 pot and you can map it yourself if you have the skill. ---- All I could manage was to get the car drivable enough to get the 40 miles to the dyno and get it mapped <img src=http://www.ezboard.com/images/emoticons/embarassed.gif ALT=":o"> Oh and sump = oil pan Exhaust manifold = headers What's the price of gas per gallon over there at the moment? I'm paying £3.67 a UK gallon for "shell Optimax" super unleaded, running a 5 litre turbo over here would fund the next gulf war with all the taxes we have to pay. Mark

When you run the drain back into the pan wont it need to be above oil leave? 93 octane is $1.55 hear. And 114 is $4.50 a gallon. Thanks for the help so far.

Petrol is almost free over there !! <img src=http://www.ezboard.com/images/emoticons/eek.gif ALT=":eek"> As long as the turbo bearing housing is above the oil level of the motor there should not be a problem as far as I know. Here are a couple of pics of my bike at the moment showing turbo placement and half completed headers. <img src="http://img4.photobucket.com/albums/0703 ...  <img src="http://img4.photobucket.com/albums/0703 ...

Crazy stuff you guy's are doing. I don't think my "nad's" will ever be big enough to ride a beast such as the one you are creating. Good luck and keep the pic's coming. I'm intrested as to how it all turns out and some of your performance numbers. Tim

Jesus Mark, I've got to take my hat off to you, thats some piece of kit. You doing any shows with that? I'd be interested in coming to look... Did have some experience in supercharging a Dodge Viper last year, but couldn't get the ECU to adapt the fuel/air ratio's correctly throughout the rev range and it burnt the cats out. Was quick though, about 670hp... shame the owner was a tosser...

exupturbo · Post by **exupturbo** » Tue Mar 02, 2004 3:25 pm

I don't do any shows, been to the BMF rally a couple of times which was not a bad show. There is a BIG bike meet very local to me every Wed eve. in the summer at a little village called great bentley in Essex and being a lazy git that's about as far as I go. Headers are nearly finished now. <img src="http://img4.photobucket.com/albums/0703 ...  Mark

Having no knowledge of turbos I'm just wondering if it's possible to put the turbo about where the EXUP valve is on a normal (sane!) FZR. Is it just a matter of space, or do the gases compress too much in the extra volume in the manifold or something? Just curious! Your getting some big numbers on the dyno, that thing must be veeeerrry hard on rear tyres!<img src=http://www.ezboard.com/images/emoticons/smile.gif ALT=":)">

dragracer1951 · Post by **dragracer1951** » Tue Mar 09, 2004 9:46 pm

The turbo needs to be above the oil level in the motor so as to alow th eoil in the turbo bearing to drain back to the motor Jim
