Ok, the 1.9l Ho head and intake are on the way. I did some reading and I think that this head wad designed for the dome top gt pistons. Will clearance be a problem with the stock flat tops on the 94 lx 1.9? If not then I believe the compression would be lower. Is this right? Next does this manifold work on this head?(exhaust manifold for a 91 on Mazda/Ford 1.8 BP series engine for rb5 turbo?) Ok then what turbo do I use? If I am seeing thelight right, if I have lower compression with this HO head then a turbo would boost it back up and I should end up with a mean little lx with killer power for very little $$. PLease advise me. If you guys fill in the technical blanks and this will all fit together. I´ll document and digitally phograph the whole procedure for all members. Thanks a Lot for the help. Erik

That manifold won´t fit a 1.9 head. You need a manifold from a old exp turbo or escort turbo (84-85) to use on the 1.9. You could also use a rs manifold from the UK but it´s kinda hard to come by. Besides that you need to worry about fuel management and timing also.

I haven´t done this myself, so I don´t know the exact specifics. There is a guy on the escortracing.com forum that has turbo´d his 2nd gen, and he used a MSD DIS-2 for timing and a fuel pressure regulator to raise fuel pressure. I am not sure but I would think you´d need an air/fuel controller to actually get more fuel in there too. If you go to the escortracing.com forum look under forced induction and you can find some more info.
In order to go turbo you´ll need one of the manifolds said above, or I´m sure a good machine shop could use your current manifold and make it fit to any turbo you want.
I didnt really understand what you were saying with the pistons and clearance and all, and I´m not sure what the compression ratio for the LX is.
My old roommate had a 99 Civic EX D16Y8 SOHC motor that uses a 9.6:1 compression ratio and he was still able to run .54BAR of boost (about 7.6lbs). I´m confident that if your motor is in top shape it could hold at least 5 or 6lbs.
