as i understand it, if i was to install a converter from a 2 liter into my 2.5 liter it should stall a little higher because of the additional torque that the larger displacement engine produces. so a good way to save some money would be to use a torque converter from a different application, rather than pay to have the stock one restalled, not to mention the inconvience of the downtime.

here are some of the listings i see for subaru......

of obvious notice, are several things.....

1. mounting: if it will not physically bolt up then theres no point talking about it...... but am i asuming correctly that as long as the converters are made for the same 4EAT tranmission, the flex plate could also be swapped, and it would eliminate bolt pattern issues?

2. lock up vs non lockup. i think streetability and long trips are important so im not even considering going to a non locking converter.

3. trans type.... im pretty sure it doesnt make sense to consider anything thats designed for a different trans. i have to assume it doesnt physically fit.

4. converter diameter.... in my days of aftermarket converters for domestic hot rods the higher stalling after market converters were always smaller diameter. im not sure i know exactly why, id love to hear some one "in the know" elaborate. it appears that the converters for smaller displacement engines are smaller in diameter..... leading me to believe that the turbo legacy or wrx converter would stall higher.

has anyone tried an of these swaps? what was the outcome?

Sorry about not contributing to this thread but I don't know much about the 4eat's.

I'm just curious as to why you like to mod automatics? I'm not hating or anything, I'm just wondering.
