after a long round of phone calls a local engineering shop agreed to lend me the kit to re tap the head and put an insert in there, usually a job done with the head off. as the engine only has to last a few more months until the low comp build is finished i chanced it and did it in situe, i also chanced only fixing the one that flew out completely as the car was strapped to the dyno and we were running out of time to get it mapped.
anyway she held together long enough to do the majority of the work and i drove her home this eve, theres still alot of work to be done but she is now fully mobile and i can put my foot down, well once i fix the other 3 cylinders.
i gave her some poke on the way home and it actually scared me, its abit icy out so 1st 2nd and 3rd are useless but the pull on the motorway is awesome, i defo think it needs a longer ratio gearbox as it hits the limiter abit to quickly!
well on to the figures, these are at .5 bar of boost and ive been told with some more time on the ignition side of things i should see another 10bhp peak (didnt have enough time with the mishap) she made a very healthy 246.5 bhp! not bad going for spare parts and favours
