If it's already a Tommy engine, either 1 he built from scratch or one he previously mapped then why not get him over to do it, he travels a lot further than Ireland to map /set up engines in cars, and i know he does lots of wrc engines still as when i went down his the week before last there was at least 4 in the build room sealed up ready to go out the door. obviously his time is going to cost but that is the same for anyone,

Plus people will say i am biased as i always use him as he is 10 minutes from my house but it seems every other wrc engine you see in car or stand alone for sale is either built or mapped by him
