Converting my 71 Gt Jr to a 2.0L. If I use a stock 2.0 Manifold, do I need a new front section? for a proper fit over my 71 Jr front section? Thanks

1750 and 2000 blocks are the same height, so should be OK. You're using stock cast iron manifolds?

I'm confused. Do want to use 1300 manifold with a 2ltr??? Or are you planning to use a stock 2 litre manifold. Your 1300 pipes of your original front exhaust section, infact the 1300 pipes all the way to the back may be smaller diameter but who knows what is on there now after 49 years. Measure your pipes, talk to Classic Alfa, ask them some questions, these questions.

Stay Well

I think Ken is right on this, it was the 1600 stock cast iron manifolds, that would fit 1750 and 2 liter cars, I suspect the inlets on the 1300's are smaller, while the physical dimensions of the would probably be the same.

That is what my Alfa Mechanic thought as well. I need a 2.0L exhaust manifold if anyone has a good one to sell/part with. I think what I need is a two piece unit pre 1974 or from 1990-1994. That is advice from the Mechanic.

You can use a 1750 as well.

I put an Abarth front section on my '74 GTV.
Sourced from this guy in Holland.
