Hi James. I have been researching this for quite a while with many tuning people, i understand that after fitting it's of to the dyno, my enquiries on this forum was to hopefully confirm the mechanically, ei hosing ,volvo specific items. I other words I went fishing. Thanks Timbo saved me time looking for that info.. My history of building and racing cars goes back to the 60s, my early efforts with computer controls started with various units on turbo rotary engines. Got booted from Heathcote with a11 sec in aroad car. Even fitted one in a mini, non turbo used a j port 10a to comply with under 2 litre class,nd yes it drives the front wheels. I thrive on being told it can't be done,unless it's from people who have tried it . over the years I came across many helpfull people and I am glad to say it's stills applies today.many thanks again
