building gsxr1000 motor and need help

[gixxerbob]

i wanted to start off by saying that this forum has been extremely helpful with almost all my questions being answered just a search away.
I am looking to build a gsxr1000 motor from the ground up.I part out 1k's all the time and have no problem stealing the cases out of one and the head off another. it will be a stock length 02 chassis for the 90% of the time it is on the street and stretched 6-8 inches for the 10% of its time on the track. im trying to build a monsted with stock parts since i get them dirt cheap.

Here is what my searches have found me so far:
let me know what you are thinking and most importantly please correct me if the years listed are incorrect:
01-02 cases (supposedly stronger than 03-08)
03+ crank (fully grooved main journals)
01-04 rods and pistons (same bore with 1mm larger pins than 05+)
05-06 head (is this the same as 07-08?)
tranny (whats the best year?, i have an 02 laying around but woudnt mind splitting a set of cases for whats best)
cams (what year intake cams are the best?)

what tips do i need to know?
stator cover has to match the year cases...
pistons and rods have to match the year block.....
crank trigger has to match the ecu and wiring.....
clutch has to match...?

thanks again for the help.

01-02 cases are strongest
03-04 trans is best
06 head is diff than 07-08 but 07-08 better
Pistons and rods do need to match
Cams vary depending on build type
Everything you got is pretty close to right, your def on the right track

since u part em out
just put in an 07/8 complete motor and all wiring/controls
on the 02 chassy
no need to miss match parts
as ur goin to run all stock
cyls will hold up fine
o7 hs bigger bore ,,chromoly rods,forged pistons,,
better head/cams and electronics
throw an go,,,,no buildin needed

will professional porting and polishing of the head set them equal, 05-06 and 07-08, or were there differences in valve sizes and angles?
i plan to use 93 pump gas and ported/polished head, shaved, dual intake cams and i alread have ape cam gears. i might consider aftermarket cams but for the +/- 10hp (please correct me if im wrong) i don't want to sacrifice street drivability.

i want to use stock gauges to keep it a sleeper on the street and thought it would be fun to build something. With a complete electrical swap i don't know if that is possible. I'v done alot of complete engine swaps but im looking for a project to occupy my time this winter.
if i did use a 07/08 motor could i use the clutch cable assy and sprocket cover to convert from hydraulic to cable.

I would listen to what John said. But if your bent of building a hybrid then put a 07/08 head, THB, ECU, gauges, airbox etc on it. Get your hands on 03-04 tranny. From my understanding the cranks from a 01-08 are all interchangeable, you just have to line them up correctly.

how is a 1070 big bore going to act on the street? i am assuming a 1070 goes hand in hand with aftermarket cams, how much hp would that gain me over stock bore/intake cammed p&p'd head. is it worth the streetability.

Very street able I rode one on the street over 2 years, doesn't run hot or anything, made 196 on motor

If u need a 07-08 throttle bodies,and wiring harness I have both

[gixxerbob]

to be honest i would just buy a wrecked 07-08. i already have a 06 that i wouldnt mind ripping the motor out of and slapping a 07-08 head on
(at that point what would be the difference between a 07-08? same rods? or should i get aftermarket rods for a 1070 build?). i would consider buying a set of 01-02 cases bored 3mm and a ported/polished 07-08 head if it were for the right price. i need to sleep on the idea of a 1070 build though...
