Got some more done on the corsa today, slow progress but it is getting there. Fitted a bottle warmer for the nitrous bottle in the back, and now have a pressure gauge so that I make sure the pressure it constant among other things. Also fitted the turbo an manifold on to mine for the first time, its all very tight but turns out that on my car the rad has plenty of room from the turbo, but the problems do now come from boost pipes as they are all bigger and routed slightly different, probably need soem fancy stuff making up to get it all in nicely.
Also managed to get my hands on a EVO 4 / 5 intercooler which should flow alot better than the diesel one i was using before. Just need to go an find it on ebay as the guy has put it on there now. Down pipe is all done also, just the holes for the sensors now need drilling (decided where they are going now).
Battery now lives in the spare wheel well, gives me loads more rome in the engine bay (corsas have them in the engine bay themselves) and hopefully take some weight out the front
