    R154 Transmission

    just wondering if anyone has swapped over from the w58 to the r154 tranny? if so, how did it work out for you? i currently am running NA-T with the gte short block setup. im looking to make more power but i need a stronger tranny. would the r154 be a possible fit?

    yes it will fit, it can handle more then the w58. but not as much as a V160/V161. but it will be a cheaper setup, which will allow you to make more power the the w58. or you could always save up and wait to get a six speed.

    what are you horsepower requirements? what's your current setup consist of? this topic has been beaten up so much and covered extensively.

    well im not looking to shatter records, i dont take the car to the track or anything. i just drive it casually. im looking to make between 500-550 realistically which i know my turbo/setup can handle. its just a matter of finding the right tranny that can sustain that kind of power. having said all that, could this be a realistic option? ive looked into the v160 and honestly its not worth it to me right now b/c its just so much money between the tranny, differential and anything else i would need to successfully convert.

    Im pushing 575rwhp and 552 fttq through my r154 not a single problem ever. Ive made over 630 rwhp as well and no problem with the tranny. Im looking for 750 plus here soon. As far as the clutch I run the ACT extreme pp and the southbend feramic six puck setup works awesome no slipping its pretty much the top of as far as a single disk goes, but if your going to buy a twin disk setup on top of the r154 you may as well buy the v160 for that cost.

    550whp for the r154 is cake. the v160 may be stronger (mainly only because its ratios are shorter) than the r154. basically since the v160's ratios are so much shorter, it sees less stress internally under load than the r154 would. in my opinion you're only paying for the hype of the v160 if you're not looking to make 600-700+ whp. i myself would consider going v160, but that's only because i've destroyed tons of r154 pressure plates, and grenaded one r154. another problem with the v160 is since its ratios are so short and close together you'll find yourself shifting a lot more than if you had a r154. with my 3.91 gears and a r154 i can go from 50-150 with just 3rd and 4th. bottom line, is my opinion is its not worth paying the 2-3k for a transmission you'll never need. unless you want to brag to your buddies that you have a six speed or something. haha.

    Sorry, not to jack the thread, but I am about to go NA-Auto to R154. Do I need to swap the auto tunnel with a manual tunnel to accommodate the R154 (or is that only for the v160)?

    No auto Tunnel will be fine.. Depending on you extension on the shifter assembly you will make 2 small 1" cuts to tuck/cut for the shifter to come through. Very easy! Btw v160 FTW, I was R154 for a week! The R154 just does not feel right, and this is coming from someone who has owned 600hp+ mk3's with r154's..

    I used the w58 mount with auto cross member, so the w58 mount with the existing 5 spd cross member should work as well.

    When I installed my R154 (from a jzx90 or 100 with remote shifter) The mount and crossmember bolted straight up to my A80, no changes needed.

    It seems the mount/crossmember for the 7M R154's are in a slightly different position.
