Done the big end bearings in my Gi. Theses are supposed to be 100bhp originaly right? is this extra HP gained from the throttle body/inlet manifold and exhaust using the same block/head as later 16valves? I Have a 98 starlet with a 16valve in it and wondered if I change over the inlet etc from the Gi's engine would I work out ok? to save having the get the crank machined and bearings to suit it then. Is there anything I can do to gain any Bhp without getting too mad or has the Gi the 50mm throttle body used in the later corollas already (vernier calipers currently missing in action so
