DialTone Posted December 16, 2005 Share Posted December 16, 2005 Ok I have a question how good are the is300 transmissions I heard they are good for about 350hp or so and I am planing to buy one and I am looking at this turbo kit for it and it makes 335whp and that converts to well over 350hp so I was wondering will I have to drop in a new transmission but either way I could get around it by running less boost but I was just wondering on what you seasoned vets would recomend me doing. hope to hear from you soon ^_^ Quote Link to comment Share on other sites More sharing options...
bartkat Posted December 17, 2005 Share Posted December 17, 2005 The automatic trans is strong enough if you add a valve body upgrade. Most of the major tuners have those. Quote Link to comment Share on other sites More sharing options...
DialTone Posted December 19, 2005 Author Share Posted December 19, 2005 (edited) Also since its a auto what do i get to make the car shift at a later point so i can have the turbo spooling more and makeing power sooner. a stall converter ? and whats a valve body upgrade and how much does it cost ?
