I have a 1972 VW super beetle convertible.?

There is a lot you can do to a stock 1600cc engine to increase the power, although its not ever gonna be Porsche like without a lot of $$$, these parts will help make it more fun. Look around when shopping for parts because prices vary.

Oh yeah these are all bolt on parts

Tune up/oil change, Bosch platinum plugs, silicone wires, cap/rotor and synthetic oil

Get a Bosch 009 distributor with an electronic ignition or the new Mallory billet distributor, these give more reliable starting - $100 to $250

Weber progressive 2 bbl carb or dual Solex carbs, these have chokes on them for easy starts when cold $200 to $350

1.25:1 rockers and solid shafts less than $150

New Empi style exhaust $50. This muffler sounds good and fits in the stock location.

As far as heat goes there are electric fan kits that go in-line with the heater boxes and increase the CFM of air into the car. There are also gas heaters available and I have seen oil coolers used with the fan blowing air through the cooler into the car. hope this helps.

Get a Hot VW's magazine, lots of ads, pic's and ideas

A 1972 VW super beetle would have come with a 1600 cc engine if it was a U.S. car. In the U.S., the 1300 cc engine was only used in 1966. Let's say you have a 1300 cc. You can easily increase power by replacing the pistons and cylinders with those of the 1600 cc engine. They'll fit in the crankase without problems but you'll have to have the cylinder heads machined so that they fit the larger cylinders. When you do this, you gain horsepower from the increased displacement and increased compression ratio. If you do this, I recommend that you switch to premium gas.

The horsepower gain is approximately 10 horsepower. In an engine that size that' s a large increment.

For a 1600 cc engine, there's not much you can do because the factory has already done a lot. If you can take the engine apart, you can change the camshaft, use slightly larger cylinders, use headers, go to a two barrel carburator, that kind of thing.

Sonora knows. Sonora been VW tech for 15 years 1969-1984. Sonora done over 1000 engine overhauls.

Owned: As i'm 18 i've got basically owned one vehicle in my existence so a techniques and that's "The Cereal container", a 1988 Nissan Skyline GXE with the RB30E 3.0 right away-Six. My customary vehicle that the family individuals has owned, different than for the single I definitely have lined below in "pushed", became the late-90s Nissan Bluebird SSS. Went continuously, had a large engine (KA24DE), and dealt with properly for a front-driver. pushed: My mum's previous Subaru Impreza WRX. It became a 2005 style with some little additions like the totally custom stereo, Tein/King Springs coilovers, MRT Rally exhaust and ECUTek eu remap.

Ridden in: long term in the past this became. long tale short, while i became 4 years of age i became clinically determined with acute lymphatic leukemia. We went to a interior of sight showroom and the supervisor took me for a spin in between the recent arrivals: a pristine-difficulty Ferrari 308 GT/4.
