Finally beginning the 1974 1.8 T conversion. Bought the donor car over 1 year ago and began stripping it out last week. The goal is to modernize the cockpit and cabin a bit to enjoy things like Cruise control and A/C and intermittent wipers and boast power a <bit>with a KO4 turbo. The donor car was a 1999 Passat 1.8T longitudinal 5 speed.
I was inspired by both Mike Bellis and Andrew Dallens conversions. I don’t have big aspirations for enormous HP gains. I’ll be satisfied at 165-175Hp. I plan on using the original Passat gearbox and custom fab the axles and cable shifters. Ideally I’d like to design the cooling system and intercooler to stay in the original engine bay, but we shall see. Attached thumbnail(s) |

Really cool project!
The 5 valve chambers look kick ass! I'm an AC guy... How does the serpentine belt route? You really need 180 degrees of belt contact on the AC compressor. Most factory serp set-ups have more. The original drivetrain has an alternator with a standard pully. The converted picture has an alternator with a "de-coupler" pully. For high rpm use I'd want to throw the decoupler in the trash. You might be able to merely swap the pullies. Good description: http://www.metroplexalternator.com/pulleys.html What he doesn't mention is the faster this pup is spun the more likely it is to fail. Lose one while driving and you'll swear "the engine is coming apart". Worse noises than a "spoon in a garbage disposer". Neat project! Nice suspension! |
