i know its a ghia but its where my problem starts. I bought this car to save myself some gas. This car isn't very gas friendly. I later find out it has a porsche from the previous owner. 1.8 liter. While the car is very fun to drive i think i need to change the engines or fix it. my questions are:
1)i cant find this exhaust anywhere? in case i keep engine, i think i need a new exhaust? Where can i find it?
2)In case i am able to sell it, what can i expect for it? It pulls very strong and it has only a minor oil leak. It now has a carb (its how i got it)
I am getting about 20 mpg...its not enough for a broke student. Im sorry to bring my ghia into your forum, but i dont know where else to go
Hi Snowteller:
Since I also went to school with a Karmann Ghia, albeit 40+ years ago, I know you should be seeing MUCH better mileage! The Old Ghia had dual single-throat carbs + Stock cam + Bursch exhaust and still got 30+ MPG.
So, I believe SOMETHING is wrong for your car, given how you want to use it:
1) Does the car have a HOT CAM? (Is the idle lumpy and un-even? Will it only idle at 1200 RPM?: that's a hot cam with lots of OVERLAP and a hot cam HURTS mileage)
At 20 MPG, you are getting the mileage I'm getting with my 2-TON Kia Sorento that I use to tow my 914-V8 which is 6.3 Liters, BUILT to 500 HP and gets 13 MPG.
2) While a Carburetor is not as strong on mileage as F.I., you should still be in the 30 MPG area. So If a full race cam is not the issue, is your Carb a total disaster?
If the jets in your carb (I believe it's a copy of the dual-throat Weber which Ford used on the old Pintos) are way too big, then you will just be pouring gas into the engine and puffing black smoke. Check you exhaust pipe (s): it they are completely dark BLACK, then the engine is running TOO RICH. Proper jetting should show you an ashy gray color. Better still, check the plugs: I'm sure you can find on-line photos of rich, lean and properly rich plugs. Too Rich is a BLACK coated plug, proper jetting is a light Brown center porcelain and too lean will have an almost purely white porcelain.
Since I was also a poor college student with a 'Ghia, I appreciate that $$ are dear.
However, since it appears that working on the car is not your "happy place" I can only suggest taking the car to an HONEST private VW shop and see if they can correct your problem. YES, it'll cost you some $$, but people you TRULY KNOW VW engines can short-cut the process and get you FIXED quickly.
If you have a STOCK cam and a correctly jetted carb, you SHOULD be able to achieve 30+ MPG!
I hope this helps,
Terry
