sort of billy,i used to own abc motorsport before i sold it and the blokes that bought it fucked it up and iv been doing my own and friends cossies since 96 and still now i build afew engines with my mate luke who owns enhanced performance..
Iknow alot of the top tuners from essex and a lot of former blokes from mountune and have learnt a lot from them over the years...
Im not saying i know everything far from it but when it comes to the yb and lots of old school rs then id say i know quite a bit!!lol
Me and luke have built and mapped my latest rebuild thats 642 bhp and 526 lb ft and if i strapped a bigger air pump to it would do over 700 bhp..
All in all iv done and been apart of alot of yb engine builds


cheers danny
