Introduction
helow hears me car its got a 1.242 16v and i whant to put a 1.4 8v in and turbo within the year tell me what you think as she is
ive just looked in to a super charger and it says you need a very strong engin becuse it takes power to make power kind of thing
i havent heard that befor do you no how much it will lower it buyso when you say 1.4 8v which engine do you actually mean? As there is a modern 1.4 8v but the PGT engine is also 1.4 8v turbo..
Either way i think its silly idea tbh. Easiest way to turbo that car would be just to take the 16v head off and replace it with say a P75 head (mpi) or late p60 head (spi) and then stick turbo gubbins on. It would have lower CR already without messing with pistons or having a decomp plate made up. Then its just a matter of how to control the fuelling etc.
that harsh boost spike the 8v turbo's have which people complain about is probably my favourite thing about my sei tub. Does make them a bit, shall we say tricky. But puts a huge grin on your face lol. Depends what your after really which way to go.
but i agree with just sticking a turbo on an 8v won't make anything much faster than a 16v na. You will ultimately be able to make it faster but a basic turbo converted 8v will be similar in speed to a 1.2 16v in all but a drag race where the extra turbo torque should win (in theory).
