914World.com _ 914World Garage _ SS H/E Question

Posted by: tat2dphreak Mar 23 2004, 08:50 AM

are the 1.7 SS Heat exchangers exhaust pipes the same diameter as the 2.0? only difference the muffler bolt up?

I have a chance for a good set of 1.7s, but the main reason I am even looking is to have the bigger(better) exhaust pipes for better flow than the standard 1.7/1.8 H/Es(non-stainless)

The 2 Liter SS Heat Exchangers do have a larger diameter which may result in better performance. However, if you want to install 2 Liter Heat Exchangers on a 1.7 Liter engine, you can no longer use your current muffler hanger and exhaust. You must install the muffler hanger for a 2 Liter engine and you must use a muffler/exhaust for a 2 Liter engine.

Stock 1.7 < stock 2.0 < (all SSIs).

All of the SSIs, to my knowledge, have the same diameter pipes. The only difference is where the muffler bolts up. All of them are larger ID than the stock 2.0 exchangers, which are in turn larger than the stock 1.7 exchangers.

Sweet, that is EXACTLY what I was hoping!

I thought I had heard that before, but I wanted to be sure!

thanks Dave! (again!)
