What options are out there if I want to go from 1600 cc to 1776cc?
I would like it to be as healthy and reliable as possible as this is my daily driver. Just trying to get some more power. Mine is a 1999 mexican beetle so I don't know if that would make a difference as mine is fuel injected and has a computer, 02 sensor and all that sh@#.. whit the ac is a bit slower so I could benefit of the extra hp
I don't want to have to upgrade injectors or anything like that.
was told that I only need to swap pistons and thats it, no machining or anything, is this true?
I believe my car has around 40hp and I would like to get around 70hp, is this possible this way?
How much will this affect my mpg?
What kit would u guys recommend, post a link if possible as I'm not that familiar with the kits available.
Thanks in advance for any help. |

FALSE!!! 1776cc with stock stroke . . . 90.5mm pistons AND cylinders require machining to the case and heads!
That small increase in displacement is NOT going to give you 30 H.P.!
Probably have a small effect on M.P.G.

Yes, machining case and heads is required.
I run an 1835cc engine that except for single Weber carb and quiet exhaust, all the internals are stock (non-counterweighted crankshaft, stock cam, stock rebuilt heads - except for boring for the cylinders) and it runs great. Runs great since 1986.
My first 1835cc engine was similar, but the case cracked in 1986 from the way they machined them back in 1976.

Thanks guys. I'll leave my engine the way it is then. The engine feels great and strong so I don't want to mess with It.
Will definitely do it if when I need to rebuilt the engine.
If I want to shoot for +/- 70hp, what would I need to do to achieve it? |

You would need to do modifications that probably would prevent it from passing an emissions inspection!

Keep your current engine and start collecting parts for the 70hp engine. My 1776cc has 60 hp to the ground on a dyno at 5500 feet. The engine offers spirited driving.

x2!..if your current engine is running well, KEEP IT. Build another engine, this way if anything goes wrong with the 1776 or 1835, you can quickly swap it out. I made the mistake back in early 2003 when I removed a completely stock running engine and sold it to build a 1903...long story short, wish I kept the original 1600. The cost and up keep negated the power gains that I received.
Good luck.
