Is that it. I was ordering a GT25/35 that is rated at 500 hp on a 2.0 liter.

Default I think he is boring out the 1.8. Not sure how much though.
The turbo I was getting is rated at 450 on a 1.8 but would still spool up a little sooner then the T4.

So it probably pumps about 54 lbm of air per minute at peak flow rate. (revised)

Default When ever you put new pistons into a motor you have to bore it out
1 or 2 sizes over. This is what I was trying to say. Lucas did the same thing. Bore it over 1mm and you get 1825cc's.

Default Not necessarily, it depends on the amount of wear....
a low mileage motor could be honed. If you're doing a performance rebuild, you might as well open it to 82mm or 82.5mm.

My 2.0 motor will be 83mm.
