Engine Consideration

Post by rpm750 on Fri Feb 13, 2009 2:25 pm

Starting to think about a engine build. I've found some engine combos on the Samba, an 1835, Case, CWCrank, Rods, 92mm Pistons and Cylinders all for $500. All machining has been done. I'll need to get some heads. I really don't want a "Power House" just a good reliable motor. I would like dual carbs but would 40 IDF's on a 1600 or 1641 work? I'm tired of mine leaking oil everywhere. It runs good but leaks.

What would you build with a budget in mind?

I'd stick with the 1641 or 1776.
1835's get into heat issues- the piston barrells are thin and tend to be weaker than smaller bore sizes- I've always been told that if you want more power than the 1776, consider a stroker crank and clearenced case- then you can stick to the thicker walled piston barrells.
I had an 1835 years ago, daily driver- lasted about 2 years, then affraid

I have a 1915 daily driver with over 30 thousand hard miles. It might use a 1/4 of a qt. in between oil changes.

Make sure you look into compression ratios for your cam/carbs. Plenty of experience to be learned from at shoptalkforums. If you go too low or too high, you'll be missing out on free HP or creating too much heat.

You might want to check out Berg's site:

If you spend time cruising around his site you'll find a wealth of information.

Where are you leaking from? Might be best to fix the leaks and if you want the other get it and build, then address yours as a back up.

Hey Jerome, yeah hang on to that case, will get that from you. Maybe next weekend, I think I'll be going to the Beetle BBQ. That case will work perfect as a base for this engine. It looks like the leak is coming from the case halves below the seal, maybe cam plug? I replaced the seal and it didn't change. It doesn't leak to bad while running but when the engine is off and the oil is hot and thin it leaks a good bit. The bottom and back of the car is covered in oil soaked grime.

Looks like a 1776 will do, 40 Weber IDF dual carbs. Not sure on a cam or heads. Would like to stay stock on the cam and heads if they will flow enough for the 1776.
