My strong suggestion is a GSXR. These engines are used predominately in DSR racing and providing you don't consistently rev them to the moon and modify them beyond limits, they are an awesome power platform. If you can make it work, the 07 -08 motors are the one's to get. If not that, the prior year is good too.
The 07 - 08 have a slipper clutch standard, and there is a ton of stuff for them, like billet pans etc. The billet pans, will fit 05 - 08 engines and possibly even earlier models. Will not fit 09 and beyond.
Anyway, hope again this helps.

Thank you very much for your advices. They will be very useful in the future!!

Well it's nick named a slipper clutch. The proper term is Anti back torqueing.
It slips when you shift down at fast wheel speed that does match the engine speed. This is especially brilliant on a BEC as cars have some much more tire contact patch than bikes. There is no loss of traction under drive unless you back off the clutch spring loading to allow it to slip more on down shifts, problem it will slip under drive. Leave at factory setting and you are golden.Either way... your engine will benefit it.
Any reason why you plan to use a 1000cc engine? I raced my DSR with a 08 GSXR and it ran awesome, but my new car has a Busa power plant and I have to say the difference in torque is astounding! I have a CNC ported head and a 1397cc kit with a custom air box and tweaked engine management it should be up in the 110 ftlbs where a very good GSXR is maybe 82 ftlbs!
Wow, Kiwimanz, you are such an incredible source of information!! Thank you very much
When I said I wanted to use a 1000cc engine, I was thinking "not to use a 600cc". Honestly, I am even a little afraid of using such a powerful plant in the car, because (if i finally build it someday) it will be my very first trackday car.
However, your arguments sound good, and if the engine won't be a 600cc, it probably makes more sense to use a busa unit and take advantage of the extra torque.

thanks for posting
Yes!! I will save this post in a .doc file! hahaha
