This is my first post here so please bare with me lol.
I have a 1973 914 speedster project car and was looking to see if there was any tips or tricks to get a little more power out of the 1.7l....currantly its practically a stock motor other than it has a awry of VW Bus dual carb intakes with a crossover tube running a single GM MONO jet carb. The body is being heavily nodded, but plan on keeping the running pretty much stock for now. Thank you in advance, Mark |

I would say dual carbs (maybe 40IDFs) and exhaust would be the easiest improvement.

I'm sorry, it does have an aftermarket exhaust on it too.
I was looking at carbs, but had no clue what size carbs to go with and won't mind spending the money on them after I get the car done and running |

As for the body, full fiberglass flatnose wide body kit, I cut the rear window section out and building a custom double humped rear deck, one price front end and using new VW bug headlight globes with custom projects beam lights and full hand made tail section with all led lights.
If it isn't needed, its not going to be on the car lol no roof, no door glass, exterior handles, trunk floor are all gone |

If you are going carbs, go with dual single barrel or get weber 40 idf's with the smallest venturis you can find.

A 1.7 is tough to improve on. The best thing you can do is be patient and find a twisty road.
IMHO a used 2056 or 1971 would be a good use of money for improvement. |

Sounds interesting...simple is best !! The lighter your car the less weight to move which improves performance....
Since your car is already carbed, you are probably better to get twin or duel 40 mm carbs either from Weber or Dellorto...that would be better than the single carb setup which I think is not really that good..... Or you may be better off, just finding a good used 2.0L engine from a friend or someone if you have some connections and can even use your stock 1.7L exhaust set up as well.... What kind of budget are you on? 1000 dollars or so? More? 4,000 - 5,000 dollars? If so, you can build up the 1.7L motor to 2.2L with nice heads, cam, big bore pistons and have a really fun car....but better to start off easily first I think...lots of people recommend driving lessons and sorting the suspension out. |

I quickly fabbed up the single cross runner and dropped a monojet carb off of a GM strait 6 to get the car running...later I'll dump money into a set of carbs.
4"s was chopped out of the windsheild frame, but I'm probably going with a Ford Escort windsheild and making my own frame so the bottom front edge of the windsheild is lower and farther forward than stock to give it more of a rake and modern look |

Have never seen this kit before. Looks like a fun project.
Are you going to keep a "rat rod" look? What wheels do you plan on using? (IMG:style_emoticons/default/driving.gif) |

(IMG:style_emoticons/default/driving.gif) I ordered a set of 4-5 lug adapters from so cal performance and bolted my stock 17" wheels from my 04 GTO on the car....they look perfect, so I'm sticking with them for now. In the I'm not sure what it will be considered.....maybe a nice looking sport rat rod? Lol It will definenatly because minimalist car....door are sealed shut (thinking of keeping them like that). No roof, no side windows, no heat or a/c, just a street legal gocart lol |

One fairly inexpensive way to increase low end performance is smaller circumference tires. Say 50's or 45's. yes the speedo and gas mileage will suffer, but the low end will be better. Don't know what 17's have done to your overall gearing, but if you need tires, it may be beneficial to go smaller. If you are driving a lot, the gas mileage may be very detrimental. At 60 MPH, the RPM's will increase also, hense the gas mileage downgrade.

I like the look of that body! nice.
As for the engine upgrades, My first thought was exactly what rnellums had to say, but to not be outdone: I have heard about a mythical beast that had a single 4 barrel Holley (modern) carburetor with a custom intake manifold. I'm not sure what your fabrication skills are, but that would add to your uniqueness. It would also make replacement parts simpler to source... Otherwise, Stu |

That is a 986 Style Slant-Nose kit from Rayco Inc with some mods to remove the roll bar.
