Project 1 from Injected65. Twin Turbo Kit

[Injected65]

I was recently tasked with converting my friends 1986 Mercury Capri from an F2 Procharger over to twin turbo's. As he is my friend I decided to build him the turbo kit versus buying one. I started off with having the flanges all laser cut at a local fab shop out of Stainless plate. The header tubing is all 16ga 304 SS, 1.75" diameter. This is really my first project using SS tubing. It will definitely be a learning curve.



I then started tacking up the headers.




I forgot to take a closeup picture of the other side but here they both are fitted on the engine.




I still need to adjust the collector length on the drivers side. Once I get my back purge setup working I will fully weld them.


Here is a picture of the turbo's mounted. I will take a closer look at the chrome moly mount when I have it back off the car for paint.

very nice build!! he`ll definately need a solid bottom end for those turbo`s!

It's plenty solid thankfully. SVO block, Bryant crank and Manley billet steel rods. The F2 that was on it before was pushing about 35# of boost and the car made right around 1200 rwhp. The new turbo's are from Precision turbo and are the new PT6766 with CEA exhaust wheels. They rate them at around 925hp each. I doubt we will make them out right away, but at some point i'm sure we will. The goal is to get the car to run 4.99 or quicker in the 1/8th mile on 275 radials. The previous best was 5.30 on the radials and 5.15 on slicks with the blower.

Looks like a great start! Did you buy pre bent tubing and cut it to fit? One day I want to try and tackle some headers so I'll be watching.

I bought all of the mandrel bends from Columbia Mandrel Bending and then cut them up to fit. The V-Band assemblies I bought from Race Parts Solutions. The collectors I think were from Stainless Works. I ended up changing how the turbos mount due to space constraints. As soon as my replacement pedal arrives from Everlast I will be able to fully weld everything up and hopefully have it running by the end of the month.

Couldn't buy everything in one stop huh. That's kinda a drag but at least you got everything.

I've read a few articles in CarCraft and some post online but I'm still a little lost on the logistics of it all. Like how in the world are you welding up those merge collectors when there is seemingly no space for the torch? Do you cut the tacks from the flanges after mock up and weld each primary alone then put them back in place and weld it all together?
