I have never heard of any turbo FTO having oil starvation problems. The biggest problem i have read about is heat but if you do all the things to minimise that ie oil coolers, intercooloers, heat sheilds, and even a turbo heat bag, you will have no heat problems except maybe on a 40 degree day.but as for the oil starvation that could maybe depend on the oil pressure. Honda's have a high oil pressure rate standard and when the oil feed lines get connected they actually use a restrictor on the line to get the pressure down, thus getting good oil flow.
IMO you dont need a decompression gasket if our only going to running low boost. Sure if you want to be running 8psi and above then you are starting to press the friendship and things could and most probably will go wrong. So its really about what you want to achieve and plan for that.able to keep standard compression if you get tougher internals.. but IMO its not worth taking the chance (might as well put on a de-comp gasket..
Even with a de-compression gasket the comp in an FTO is still pretty high..)
What, are you talking FTO's????, cause there are just as many as any other car, its just all about the $$$. There's guys here, on the coast who will do a rotary coversion for ya but its going to be upwards of 30k.Maybe its just me.. but I find it hard to believe that there aren't more possible engine conversions than the few that have gotten regular mention.. maybe someone just needs to be a bit more creative .. I dunnno..
Also you could put the 1.8 GS engine and have next to none of the problems you will have with the V6.
But at the end of the day, IMO the best power for money is to do the 6A13 conversion. You can pick up the engine for 1K, its a straight fit. Just need to modify the turbo setup and your pretty much good to go.
