Just thought I would start the ball rolling on my project thread.
Been toying this over for a whiel as to what i want to acheive from the car....
As you can guess from the title 450bhp is the ultimate target with as much torque as I can physically get.
Current baseline figures from RR day are:
314bhp
309.50 lb/ft torque
Stuart and I are on the Rolling Road tomorrow so will post current progress.....

I will be watching this one very closely indeed. Best of luck Dunk, will be nice to have one of the best Imprezas around on the site. Certainly a good starting point 8)

don't know too much about the block in your scoob but i knew the ej20 needs shed load of money thrown at it to see over 400bhp but i'm guessing it'll be doable in the 2.5 lump, goodluck with it, it'll be a rocket with 450 8) looking forward to seeing how you get on tommorrow too.

good luck mate, will be very interested to see how you get on. maybe able to help you out with a bigger turbo if you like as I can get them made to your specs.

bigger turbo is def on the list
either a TD06-50 or AFP6-49 both using the TD06 framework and Garrett compressor wheels at 49lb/min airflow. Both should be bolt on (ish) and give full boost from about 3000 rpm onwards on my car
Both should be good for 450bhp :smoke:

That will be shocking with 450 ... Are you going to have to uprate the clutch?
