ok just thought i would update some people i dropped off the zx10r engine today to have all the internals done,

new turbo pistons and new rods, lots of other things to do also, will be a few quid lighter after this lot but hopefully worth it,

once it returns the turbo kit will be fitted and looking forward to 250+ bhp nice

should be a laugh and hopfully fingers x some reliability to it,

ill keep an update and post some pics once i start fitting all the kit in,

so sometime soon will have a standard engine for sale and complete exhaust system for a zx10r will need to recoup some £££ as will need a holiday after all this work,

cheers all
sean

if you dont mind me asking how much is this upgrade costing?

Sounds nuts and i like it

Hi Well

just to start

rods are around £1000
pistons £650
labour£600
parts and other things like cam chain and manual tensioner thicker gaskets and some other parts requires prob around another £400

then the turbo kit which i got cheaper as was a used kit but you could add another £3500 - 4 on top of that if it was a new kit,

then the exhaust a new 7" can around £300

so as you can see it all adds up

they do an install for around 3.5k for a busa giving around 250+ bhp but no internal work etc,

i am going the full hog on internals as think its a false economy if not,

if goes bang its a new engine and all that work again etc so we shall see,

i will also do something about oil surge at some point also prob an accsump as i have had good results with them in the past on a zx12 and a blackbird engine,

oh there goes another £350

better go before the wife sees this mail thats a very nice holiday and she dont know what this is costing

cheers

£650 pistons??
Are they custom????

I am looking at turbo BEC installations at the moment too. Are you fitting an intercooler or water injection to the ZX10R?? Have you spoken to Paul Fisher at all??

link to Pauls car

Sean,"INDY BIRD",has bought my old Indy ZX10R from me last year,and the turbo kit,Sean is now doing what I should have done in the first place,to get some reliabilty from the engines,as it was starting to get a little expensive for me at a new engine every 250 miles,but when I started the build back in 2007,due to the engine being new to the market,no uprated parts were available,uprated pistons and rods are now available for this engine,so you now have the option if your going the turbo route on this engine.But I also took the wrong advice from Velocity Racing who sell the kits,saying I could run stock internals on 6psi boost,but you live and learn,I am confident Sean will get it sorted and end up with a mind blowing car.

Hi Thanks for the mail paul,

yep pistons are custom make specific to the engine, and what application they are for etc,

only one other company makes a good turbo piston for this engine muzzys in the usa,

but i am sticking to a supplier in the uk just incase any issues as easier to resolve and has a good rep and proven record with the company doing the engine mods,

yes it will cost me the rods being the biggest hit and found a comp[any in the usa that now are doing a dry sump kit,

as paul said engines are new but now we are starting to see some companies doing good after market parts, shame they wasnt there when paul was originally doing it,

hopefully i can do the build he wanted to achieve and let him unleash it at some point as i know paul is a good driver and will get the most out of the car, more than i can,

maybe set some good lap times????

still looking forward to warp factor 10

250bhp at the wheels will be on pump fuel anyhing after this i will be looking to have to use 50/50 mix of race fuel which is expensive but gives you shed loads of more power and can turn the boost up,

i will be fitting an intercooler to the car i have 2 too trial a modified sierra 4x4 cosworth one and a another of unknown origin, but has the capacity for this install,

i may run aquamist in the future but time and money will need to see as want to get the car ready for some track days this year pref by may ,

thanks all

Hi, I'm also looking into getting a bit extra from a bike engine, can I ask why you chose a turbo over a supercharger?
cheers
Ed

no real reason why chose turbo as paul mentioned earlier i got the car and turbo kit from him last year,

now decided to fir it all,

both will deliver good results both will have there share of problems,

mk's supercharged gsxr was a little tricky to set up mbut once done was a very quick car.

i suppose depends on your budget and how much power increase you want, if you want a lot as we all do then internals will need to be done and that costs if only and extra 50bhp you should be ok but gaskets and head bolts may still need to be done to lower the compression ratio for turb or scharger application,

who was you thinking of using then????

some dont always deliver what they say they will do so do your homework or could be expensive

good luck

you can never have to much power

I've got quite a few bits piled up in a big box to turbo my R1 (5PW first injected engine). People have run a few psi on standard internals and got decent power gains.

I'd go for a turbo over a supercharger as the supercharger needs power to run and from what I've read the power delivery is quite linear on turbo bike engines. Also in some ways its less work as you've got got piping and a manifold to make whereas it could be harder work to make up the supercharger bracket and take drive from the engine etc. Guess it depends on the engine and application.

For me I'd prefer to drop the compression and run a standard engine but not chase big numbers, 225 to 250bhp from an R1 (with a big hike in torque) is fine and allegedly reliable on a stock bottom end. Just a thicker HG or 2 std HG's to drop the comp ratio.

But its on hold for now as I think there is more speed to be gained from more experience behind the wheel on track (in my case at least). Once I'm happy with that I'll dig out the mitsi turbo, flanges, megasquirt etc etc.

i think if you are to around 4psi you can get away with it on some engines but for how long not too sure???

but i know i will want more than this after a while as it becomes addictive so going the full monty,

250 bhp would be pushing it i would have thought on standard internals,

i know the busa can stand this type of power on standard but no experience of and r1 maybe speak to some people in the know,

if they have been put on bikes prob ok but with the extra grunt required to pull atleast 300-350 kg more that puts more strain on the engine im sure so do you home work or as paul said will be a new engine every 250 miles or so, and could do some serious damage to the turbo if blows,

i am having to have it overhauled as oil has gone through the turbo at some point when poss the last of pauls engines blew???

good luck though im sure you will have fun learning the car in its standard form and agree with getting the most out of the car before extra power, me i am just impatient so get an idea and just run with it,

just hope its a good decission
