1600 to 1915 question

I would like to upgrade my Mexi-crate 1600 to a 1915. Can I use the Dual Weber 34 ICT's? Is there any inherent problems with these blocks?

You are going to have to split the case to do this....The case and heads must be bored for the oversized cylinders..... While its opened up, you could install another (healthier) cam for improved performance...... The single throat carbs will work with the stock cam and some less radical grinds, but when you start looking at 90+hp, go with Dell or Weber dual choke carbs.... The idea of a carb throat for each cylinder has merit as you effectively are tuning 4 one cylinder engines and can get the idle down low with some pretty wild cam grinds....

Just my .02

I am running dual 34's now. Can I re-jet them to work?

I'm running dual EMPI 34's (Weber 34 ICT knock offs) on my 1915.
Aircooled has the jets you'll need. Good folks.

If you split the case, while you're in there get a nice forged and counterweighted crank too.

and why not stroke it too.

with the machine work and new parts you'll need to buy - it's only adding a few hundred more to go to a 2110 and you will definitely notice the difference.

Unless you know for certain that the case was not previously fondled, I would buy a new ready to build case speced the way you want it.

Jim, I have a 90% 1915 engine for sale. Add cam, lifters and intake stuff and you're about complete. If you keep your 1600 intact, you could sell it and almost cover the cost of the 1915. One cam lobe and two lifters let go 10,000 miles after rebuild by a respected builder. Wrong oil or bad cam/lifter material could have caused the damage. Consult a few experts off line and if interested, email me direct dstroud at xplornet.com and I can list the parts, sent pics or whatever.

Thanks guys, it's a lot to think about.
