Alain's Brasil-style turbo Fox build

4 minute(s) of a 85 minute read

John: Thank you! The motor is running - it starts right up but it's got a rough idle due to my injectors (I have newer ones coming). The current ones are so bad that when testing them, if I press down on the air plate just a little bit (trying to recreate an idling situation) only one injector sprays in a nice pattern; two don't spray at all and one sprays in pulses. They are not bad at part to full throttle though, and I could tell so in a couple of test drives around the block 

Still gotta put those radiator surround pieces that Rob gave me, that will be a nice addition!

Chris: Thanks for coming by! It was great to meet you as well and talk some Fox; thanks for the gifts and for the ride in the Wagon - it drives SO nice! I hope you enjoy the rest of your time in Montreal, the concert and the vw show/camping on your way back, you're welcome to stop by again anytime in the future and I'll be sure to visit next time I drive this Fox to your neighborhood!


Looking at the pictures above I realised it's missing one of the engine compartment all put back together, so I took one last night:

Thanks things are really fitting together and this is definitely the funnest part of the build.

Did a few things lately; repainted the front fenders, painted the bumpers and added the blue striping to match the GTi side trim (rear bumper is still not mounted, just kind of sitting there), also painted the doors, hood and trunk lid. Re-assembled the doors including the vent windows I brought for it, and mounted everything.



















Gotta say most of my time has been spent getting the engine to run right - chasing a mysterious vacuum leak, changing and cleaning injectors, etc...

Turned out what seemed to be a vacuum leak was actually my diverter valve, which stays wide open at idle, and though not a true vacuum leak because everything happens past the air being metered (no extra air is coming in), it was hurting my throttle response big time maybe because one of the ports is connected too close to the air plate on the FD, who knows. Later on I'll fix that issue by adding a pressure switch and a solenoid valve, which will effectively only allow the DV to open when there is positive pressure in the charge tubes before the throttle. I had done this back when I was running a blow-off valve with good results.

The engine is running pretty well now, time to fine tune mixture and timing for boost and emissions. Also going to do all the work to repaint the quarter panels, then mount the rear bumper and enjoy the car a bit
