150rwkw/200rwhp out of an RB25DE is going to cost you.

Machine work (porting will have to be done and getting the compression up, 10.5:1 probably won't cut it, you should be trying for 11:1 - 11.5:1 for 2.5lt and costs for big cams also)

About - $4000

Aftermarket ECU - Min $1000 then to wire in and tune another $1000

Decent Extractors - $1000

Labour - min $1000

Cams and springs - $1500

Oil an water pumps - $500

Exhaust piping - $750

Lightened Flywheel and new clutch - $1000

So about 11G should net a figure around 150rwkw probably 160 - 170rwkw, but in saying that people would say you spent all that money and get such a tiny power figure, but really that setup would be good for a mid - high 12 to low 13 sec quarter pass which isn't slow for an N/a

umm..id like to do the same to my 34 is he said that hes got an auto soo wat would be the kw without the clutch
