Stu/Nick, thats pretty much the plan. Once Arch has repaired the chassis, I'll get it rebuilt and roadworthy. I'm not looking for monster power, but think 160-170 would be a good place to be. Not particularly interested in full on rebuilds forge etc. mentally was thinking to open the inlets up to suit the TB's while the engine is out, and when i have all the right parts (ecu, 4 branch) getting it all mapped and enjoy. I'll look into the air filters, the item I have bought has no filter on it. I assumed I'd have to cut the bonnet what ever, but if i read your wording correctly it will fit witin the confines of the existing hood? Cheers for the input gents Alex
