thats not an easy question to answer! but things to consider;
1;exhaust headers,
2;power comander ( if fuel inj)
3;clocks
4;diff (if your going for a power hike)
5;mods to propshaft
6;fitting,wiring,
7;rolling road session to tune
which ever way you try to do it,it wont be cheap!

just trying for an rough est

To add to daniels list

engine cradle
high pressure pump and return fuel line if fuel injection
airbox/airfilter
new hoses for plumbing

also alot of engines are not sold complete, so the throttle bodies, starter motors might have to be considered...

Not sure on what yours may be worth as a package, prices are bit mad at the moment, so might be worth waiting till prices pick back up.

i think speaking to ab performance and finding out what your options are for increasing the performance of your engine may be a cheaper move than a complete swap, at least that way you keep your bodywork, exhaust , prop, diff, etc etc. andy is the honda expert so you wont go far wrong with him.

Stick a turbo on it, made mine come alive !

Major costs are:

Turbo
Lockup clutch
3.14 diff
Intercooler

and a lot of making stuff as cheaply possible

Its all well and good upping the hp but in the real world the increase will actually benefit you very little - exceptions being when driving two up.

Turbo by all means - but it places massive loads on Clutch and G'box.

Going from an 893 'blade to a ZX12R and the difference was smaller than you think. Two up it made a massive difference!

You can throw loads of money at gaining 50hp or more but I would wager that for 50hp you may be spending in excess of £1000 when the dust settles... (no turbo) do you really think it is worth it?

I'd think twice - but the choice is yours!

Good luck either way!

just had a price of 2k for it to go to 144/155 bhp so not worth if

Quote for increasing the BHP of your Fireblade? (what does that include).

I am in a similar position trying to decide what to do with my 893cc engine...

My thoughts on the cheap option would be to go for the lastest R1 on carbs (2003?), build the engine cradle to reuse the existing prop length (if possible).

Is it possible that the exhaust headers could be adapted to fit the spacing and size of the R1 ports?

Of course thoughts also turn to the ZX12 - so it intrigues me to read that it won't make a 'night & day' difference over the CBR900.

The RGB lap records show B & C classes as similar, with A slightly quicker (actually > 4 secs at my local circuit).

I guess it depends what you do with the car... +4 secs a lap would be nice! (depending on overall cost), but would move the next sprint class for speed events (less important to me).

Hence I'm interested to know if any CBR900 upgrade are viable... ?
