I have been lookin into someday attemping to turbo charge my 94 gt. I have been trying to learn about the whole process and what it is going to take to do it ( i want to learn to do it the right way so i don´t screw anything up ) . I understand alot about what you are talking about when talking turbos, and i know my way around the engine fairly well, but never got into turbos enough to really do it yet. I feel the turbo is the biggest add on with the most power improvment. i´m sure there are other people here that are thinking of trying the same thing. I would like to know what turbo is best for the 1.8 and what will i need to get it working without major mods. what do i need for my exaust manifold and and stuff like the oil line for it and intercooler, and what engine mods do i need to achive this. i´m not looking to race it so i don´t need something crazy, just want to add more power to it, everyday street use with as little mods as possible. just want a basic turbo setup. i´m sure there are others that have the same questions that i have. are ther any write ups about it, as for the 1.8. i am trying to learn as much as i can before i attempt it, and want to do it right. i need my car for work and don´t want it down for weeks, or screw it up. can anybody give some info on this subject. it seems alittle harder for us since we don´t have the aftermarket options like the hondas do, like what works from other vehicles. I have learned alot form this site but there are the little things that i am not sure of. info on this subject would help greatly

I´ve been trying to get one of our (shall go unnamed) gurus to write up and article for us. I´ll see if I can´t fan the flames.

i new there would be alot of others who have the same questions, i just don´t know what works the best, its not fair we don´t have the options like other cars . why shouldn´t every escort have the right to be turboed. i would really like it if somebody could write something up for us to help explain some things were not sure of. is there any other site that has info on this subject anywhere

I´m not a guru at all, but I am in the process of turbo´ing the 93GT.

What you need as far as parts depends on how exotic you want your set up though.

But we all know going turbo means having a turbo. I spent alot of time plugging numbers and the best match to the GT´s 1.8ltr is actually a T3 with a .40 trim....however, IHI made a VJ-20 for the 323...so that´s the easy way to go. You´re going to need a manifold to get the exhaust to the turbo, most common is the manifold made to the VJ-20, but it could be modified to fit anything.

When turbo´ing, since its a custom project you should probably intercool aswell. Plus, getting the air cold will add a few extra horses and help your engine.

You´re going to want a Blow Off Valve, prices go from 20-400 bucks....anything that will blow off excess pressure while shifting to prevent backspin on the turbine will work.

Well that´s the basics, now to understand what you´re doing. By spinning a turbine wheel with exhaust gases your are spinning an impeller that is compressing air on the intake side. The compressed air has the effect of a higher air density (like going from 5500´ to sea level), except you actually surpass atmospheric pressure quite a bit. So, as more air is forced into the engine the engine creates more power (rough estimate is 15 horse per lb of boost). 14.7psi is 1 bar in the import world if you weren´t familiar. 1 bar is 1 atmosphere of pressure. So that means at 14.7psi you´re forcing 1 atmosphere over perfect vacuum. Realistically though, if you dont upgrade your fuel delivery system 5 or 6psi is pushing it with the GT´s.

Other then figuring out all the numbers and such, the actual turbocharging part is easy. Its perfect engineering; using exhaust gases to compress intake gases.

my only question is, i see all these 91 scorts with turbo, what about my 89? can i just follow the example the on the main page or is it different for these older scorts?

The theory of turbo´ing will work on any vehicle, even your 89. However the 91-95´s use the Mazda BP8 which is a great motor to force induction on. If you have a different motor you can still do it, but you´ll have to be the pioneer on figuring out where your boost limit will be.
