Alright as some of you know. Im starting a turbo b20 project. Im also doing this as cheap as i can but still the best that i can do for the most part. Im starting this thread so you guys can see how im doing this if you want to try it for your self and also for the people who have already turboed there cars to tell me what im doing wrong. So this is going to be a big information thread lol.
Alright ive started with a td04 turbo from a wrx. I probbaly should of gone with something like a t3 since about every manifold you buy will bolt up to one but remember im learning as i go lol. Im planning on running 5 psi no more until i get the right fuel management and a nice intercooler.
I started with a cheap ebay ssautochrome h22 turbo manifold. I got this one because the stud holes didnt seem to far off and only the 2 inner runner were a tad bit off. I got the manifold and discoverd that it needed a little more hacking then i thought it would but i should be okay. I also discoverd with all the wrong tools how a pain in the ass cutting threw stainless steel is!!!!! Im using a 12:1 ratio fmu for now. My car runs real rich as it is right now since i dont have the ect sensor pluged in so im helping this will help me out a little too for now. Im using a external tial imitation wastegate with a 5psi spring. Im using check valves to trick the map sensor. Im still working on various flanges that will mate my turbo to the mani and every where else i need them. I havent got to line anything up yet in the engine bay but it looks like it should all fit just real tight. Im waiting to put everything in once i get it all together and have everything infront of me that i need.
Here are some pics of what i have so far. I also have a DSM BOV comming from ebay.
Thats how much i had to cut out of the manifold. I know it looks haggerd but im still working on it. Im going to use washers to hold the sides where i had to cut all the way threw. It should move around to much because the 2 upper holes on the out side were dead on so im hoping they will keep it from moving around. Porting out the 2 inner runner seemed harder then i thought since i started making them bigger and then found out that ssautochrome had the runners go all the way threw to the inside side of the flange.
BTW: does anyone know if i did this right? I think i did but im just curious. This is the home made check valve map sensor trick. (aka missing link) One end is going to connect up to the throttle body and the other end to the map sensor vaccum line.
