Bolt on power enhancements, what would be your first choice? Options

[PinetreePorsche]

6 years and still running perfect! 2.0 4cyl. Bosch CIS KKK 26 turbo. 9lbs. of boost on the street 200 HP, 14lbs. on 100 octane race fuel on the track (IMG:style_emoticons/default/driving.gif)

A lot of faiarly cheap power and a few good years--just what most of us want. So can you draft out the whole conversion you did for us to follow? What fuel feed source--EFI or carbs? Who's ? What was approx total cost (starting w/a good motor)? Some of us would love to experiment a bit if we had good guidelines (and temp. monitoring at the cylinder head). -Chris H.

Chris,

CIS is MFI. It was used in rabbits and 2.7L /6 engines. I don't know how he did his his conversion, but many people in the watercooled world have done CIS turbos (though they usually use the later version of CIS as found in MkII IIRC, golf/rabbits).

1. decent muff system
2. periodic maintenance
3. electronic ignition
4. Tires

CIS & MFI are entirely different animals.

Years back, Wayne Baker used a BMW (2002 IIRC) MFI set up on his IMSA 914 4 banger race car. He was very successful.

Yep, I mis-typed. CIS is a mechanical fuel injection system since the pump is the only thing that needs to be electrically powered, but not MFI like found on old bimmers and long hood 911E/S's.

If the truth is told...lots of 914 owners <from my point of view -and yes Elvis and Michael Jackson are DEAD> look at the $400 bolt limit as what we can spend and hide the receipts from the better half! (IMG:style_emoticons/default/av-943.gif) Bill

my favorite bolt on is Chappy's engine (IMG:style_emoticons/default/biggrin.gif)

CIS is a great simple system and adapts to boost easily. Add a boost sensitive WUR from a Volvo or Audi turbo and the fuel system is taken care of. In the early days of boosting rabbit motors, a LOT of us did it. You would still need to deal with remapping the spark advance curve, not sure how to do that with the stock parts available for the type IV, so you'd probably end up with aftermarket ignition.

After about 3 years of a bunch of us mucking about, we found the limits of CIS pretty quick. It's simple to get installed and started, but it gets complicated to tune. Because of that, a LOT of us went to Digifant I injection sourced from G60s. Cheep, easy and more than capable. I'll bet it'd even adapt to a TypeIV pretty easily.

The result of all those mistakes was eventually summed up into a single doc: http://www.not2fast.com/vw/stuff/easy200.html

You'll find the same doc all over the 'net

if I could vote again after driving my 914 for 4+ years, I would still vote for "complete exhaust" (IMG:style_emoticons/default/beerchug.gif)

My kit wasn't just a Turbo kit, it was also an EFI kit with direct ignition AND included my DTM for the 914. It literally was every part from the intake to the exhaust pipe, all you needed was a longblock.. The best part is that every part was designed to work with the rest of the components and install in one weekend.

That was about 5,500 bucks including a brand new Turbo...
BUT cheap bastards pissed me off- that happens..

Wow with a DTM and an ecu setup to control it that is really not to spendy considering the engineering costs to develop a kit that works well and doesn't detract from the original setup. I hate to hear that the teener's didn't just jump all over that. And I am sure you picked just the right turbo, so it spools nice and quickly.

Tis a shame.... Raby if i had a TIV and some money I would be buying a kit from you.... hell i wish i had a type 4 so i could run that sick cable pull linkage setup you made for independent carbs or throttle bodies.

Keep up the good fight Raby

This is the best one:

[get off my lawn]

There aint nothing, and I mean nothing like the feeling you get when the intake manifold pressure goes positive.

[dflesburg]

there is no replacement for displacement.

[iamchappy]

Solid Rocket Boosters but hard to control..

Next best thing ..... My engine....Ha
