So an exhaust leak has appeared in my rb20det, to be honest unsure whether it's the exhaust manifold gasket (half are studs and half are bolts :?) or turbo outlet gasket (only sporting 3 out of the 6 bolts and studs. So im planning to replace all the gasket around the turbo and exhaust mani at the same time. So I'm swinging between either buying a few Cometic gaskets to cover my needs??? or buying a full complete OEM gasket kit (I know I don't need them all but its just as cheap)??? This car has been getting built for a few years now, so I do plan to get some power into her. I already have a cometic triple layer steel head gasket and arp head bolts. Basically my question is, if I plan to run say about 18-20+ pound of boost in the near future, which gaskets would hold the boost more efficiently and more safely? 'Cometic or OEM'?? I have done a Google Search and what not, but didn't get me the info I needed Thanks people

hey everyone, love the site. allright well, i have a vs calais that i am putting an rb25det into, bought my donor skyline (r33) last week, was thinking ill take the engine out and sell the stuff off the skyline to hopefully make the money i spent back on it. just had a couple questions, 1# what is everyones opinions on a quality aftermarket ecu, the car is a manual, has 290rwkw for now. it still has stock nissan ecu. 2# would 1000cc injectors be good for around 300-350kw?? or would an upgrade be in order and if so at what power would it be worth changing them over. 3# what would the problem be if when i start the skyline it starts blowing out light smoke from the oil catch can? 4# and would anyone know if i could use a vl manual front half of the tailshaft and have the original vs rear part? anyone that has done this to a vs would love to talk, or even if someone could send me a link to someone thats done it would be a great help. and by the way i dont need anyone telling me to ditch the commodore and keep the skyline, have alot of love for my calais and its very neat to. cheers guys...
