I have considered boost but here in the uk it would cost me more, i can get a 30,000 mile B18c5 delivered to my door for 1000 pounds, and my freind can put a ITR map on my ecu for free.
The Turbo option would cost me more as my car has 140,000 miles on it and i would buy a lower mileage B16a2 and put that in if i was gonna turbo.
Anyone know about the sensors i asked about further up the thread??
