Power Auto

[ShinmaTsunami]

Hey guys, I have the 3sp auto 4A-FE in my 97. I've found parts to raise the horse power little by little.... But how you do raise the torque? Are there performance torque converters, or am I able to put a hi capacity clutch in it? And info would be greatly appreciated.

Hello,

I might be missing something but I don't see why there would be any difference in tuning an engine with an auto box compared with one with a manual.

To get more torque you can increase compression (new pistons / cylinder head) and change cam shafts. Or you can turbo or super charge the engine(but then you should not increase the compression). That'll give you more of both.

Normally the torque converter on auto boxes can take a fair bit of abuse (extra torque/power). Might need extra cooling if you really push them but otherwise there is actually less to be concerned with on autos.

Yes, you can get performance torque converters. They can be expensive.
