Yesterday i finaly raced my duster against something so i figured this build if far enough not to be embarassed about showing it to you guys! Dont have alot of time today so i will add more info and fix things in this post later.
I have been working on this for about a year and a half in my spair time, the goal was cheap easy turbo power, not reliabe, not pretty, not safe, not even that much power. I wanted to turbo this car since i was in high school following ondonti"s build (like 2010), and the car got to the point that it was going to be scrapped if i didnt do anything with it, so i had nothing to loose.
The idea for a rear mount came from a craigslist ad for a "rear mount setup" that had a turbo, oil pump, and a few other things. I was just after the oil pump but It turned out to have a turbo, wastegate, BOV, oil pump, airfilter, and a homemade manifold from a 3.0 ranger. Since it was from a 3.0 i decided to use it all and just modify it to work in the trunk of my duster, this saved me alot of fab work. The build is far from done but im focusing on other cars so id like to think i got to a decent stopping point.
So onto the car itself, its a 1993 duster, auto trans, and before i got it it was crashed a few times then it blew up on the way back from the junk yard, so now it has an unknown milage 3.0 from a labaron, it ticks, burn oil, and has bassicaly no oil pressure after about 5 minutes of running (got sick of the oil press guage reading zero so i pulled it out hahaha). The turbo is a used 50trim .63AR ebay t04e, waste gate and BOV are all used ebay junk, aswell as the AFPR, the only name brand stuff is a Flojet oil pump, a Vortech 14:1 fmu, and a set of 36# injectors from a supercharged gtp. Other than the turbo setup and fuel mods the only other mod is a larger throttle body. Sparkplugs are ordered and i am looking into meth injection at the moment.
The tunning is a little complicated, i started off on stock injectors with a 14:1 fmu at 4psi of boost, this dosent work with a vortech because it adds pressure from 0 base pressure, so at 4psi i had 56psi of fuel pressure which is hardly mor than stock. i bumped the boost up to 7psi and that gave me 98psi of fuel pressure, this got the af ratio to around 12.7 ish but only at full boost. When i put the 36# injectors in i did the math and found out that i would need around 38psi fuel pressure to get the same AF ratio, so i used an AFPR to lower the base fuel pressure to around 18psi (as low as i could get it to go) and i set the fmu up so that it only affects the AFPR, and i left the stock FPR hooked up so it cant go any higher than 42psi, this turned out to work pretty good, my AF ratio is around 11.5 at 8-9psi of boost, and it starts to get extra fuel around 1psi of boost, AF ratios stay pretty consistant though the boost range, they peak at 10.8 for a half second around 4psi of boost. All this could be better if i wer to buy the correct ratio disk for the FMU but it just happened to work out that i didnt really need to. Also i have the vacume referance removed from the stock FPR, if it is connected it will raise the final fuel pressure by however much boost is running, not alot but it might help fuel an extra 1-2psi of boost with these massive injectors. The car appears to have around 200HP bassed on the race we did yesterday, that is bassing it on my 1.8t gti that should have around 200-210hp but less torque.
Here is a pic of the car as it sits today
A few pics under the hood, im hoping to make it look stock at some point, mostly just put the top of an airbox on it, and hide the fuel pressure regulators.
This is a picture of the trunk when i had it to the point that i could drive it under boost, (check out that 90* angle on the down pipe!!!!)
And here are a few pics of how it sits today, i made a box with a vent motor to controll the fumes, it has an aluminum lid aswell thats not in the picture
And here is a pic of the intake pipe, Its 2.25 inch electrical conduate, i used it cause you can get mandrel bent corners from menards and its fairly cheep. pretty heavy but it does the job and can take a hit since it sits so low.
