You could fit wider drums but the centre of the drum wont fit over the axle hub which would be very bad. If you dont want to change the offset of your rims (which would be the easiest) you could put a spacer between the diff flange and brake setup. Problem with this is it will pull the axles out of the centre the thickness of the spacer hence you will need longer axles. Got any ideas???
Forgot all about headers, too busie thinking how much of a pain in the bum it was to change the plugs in my 351clevo powered XY. Could have joined a circus with the skills i picked up doing that.
Not sure about the wider drums but I am fairly sure that spacers are legal as long as they are approved. One stipulation is that the spacer must be fixed to the hub. The problem with this is that they are usually too wide, 20mm I think. Have you spoken to an approved engineer or RTA down there for a YES or NO answer?
I have seen a 351 windsor in a MINI, The dude was sitting where the back seat use to be, FREAKING CRAZY. You picked a pretty heavy donk but with all that weight over the front she will smoke the fattest tyres on earth. As for the spark plugs just cut inspecton holes in the strut towers and brace the S##T out of everythine. Good luck with conversion and up the mighty CLEVELAND.
There all good suggestions to temporally fix the problem but I think the issue here is the fact the boost is taking an alternate route through the donk ie out the dipstick tube instead of out the exhaust. I am guessing the donk is standard and done a few kays. Give it a freshen up with a good quality set of rings to suit turbo application. But for now just screw down the boost. If you keep sealing up the escape routes you will just start blowing seals.
Pull the plugs out and crank it over, Get someone to watch too see it it shoots water out the plug holes. If it still wont crank over try to do it by hand to make sure the starter hasent packed it in. If that dont work dump your oil into a clean container and inspect what comes out. Seriously though I reccon its a broken FREPPS
If NOS can be put on a SCOOTER it can be put on anything. I agree with B210guy, a '50' shot wont hurt a standard donk and with a little knowhow it wont be to hard to fit. Hell there are kits out there to fit onto those little kids bikes. The NOS bottle is the size of one of those soda streem bulbs. PRETTY COOL HAY.
