Boosting an 87 Jetta GLi...Anyone???
Ok, after I finished my HMT my friend, who hates hondas, decided to boost his VW. His car looks awesome, custom paint job, dark silver metallic, 17's and a nice exhaust. That's all he has but the car looks damn good. The car has a weird intake/fuel injection system. The injectors are like on a box by the passenger fender and then some lines run the gas back to the cylinder, weird *** ----. Have anyone seen this engine before, or boosted one of these before? Any info would be good, I've been searching but can't find anything on yahoo/google on that year model.
thanks

don't boost that engine, not worth the effort. Get a 2.0 from the mk3s on up and boost that. I turboed a 98GTI with a 2.0, has injectors like ours, and will bolt into that older chassis. You can get them super cheap too, since everyone wants VR6s and 1.8ts They are like the D-series of Honda motors, and the tranny might even bolt up, send him to VWvortex.com
what you're looking at in your friend's VW is called CIS - constant injection system. simply put, it's a form of mechanical fuel injection... people have turbocharged CIS motors in the past (i've only read about it), but it's not worth the trouble IMHO.
He even has a 16v motor on his garage that has a regular fuel rail and injectors, but the electronics don't work out, it bolts in but the computer doesn't plug in and he didn't want to go thru all that ----, but I guess is better in the long run. He went to a Shop to ask if it coul be done, the guy quoted him $1500 just to make the pipes and put everything together, my friend had to give him a manifold, turbo, downpipe, intercooler, all the pricey parts, I told him ---- that, If he's going to juts buy everything, we'll do it. I'll research this more to see what we can do

I'm in the process of turboing my grey '87 Jetta GLI right now.

The 2.0 from a newer car should bolt up physically, and it makes a really good turbo mill. Wiring is another story, the 2.0 8v is almost a plug+play swap into later (<90) cars, but the wiring in earlier cars makes it more of a challenge.
I've ditched the CIS completely and I run Megasquirt with the stock ignition for now, but I want to garbage the what's left of the ignition and use an MSD box or something before I actually put on the turbo.
I also considered SDS, but I am a cheapass so I had to use Megasquirt.
A normal set of injectors and a fuel rail bolt up to the stock intake. You just have to get these injector inserts from the dealer, and there is no factory fuel rail for the 16v engine- I had to pay entirely too ------- much for mine.
