ive got a 1.8 xr2i lump and my plans for this year are as follows.

4-2-1 manifold straight through + decat.

fats road cams or something similar

bike bodies or throttle bodies (probably will run megasquirt as a friend of a friend can set this up for me fairly cheaply.)
will also fit new end shells and fit arp bolt when the bodies go on but not before.
what sort of power will i expect from this????

what headwork could i do aswell that would help these mods?
