Cheaper alternative Hi all, I'm looking for a cheaper alternative box then a T56 for an LS1.
At the moment I can't afford a T56 and sort my engine out so I need a cheaper box until I can recoup some money for a T56

short answer, no
with enough $ the TKO 600 and adapter plate "may" be a possibility but that certainly would not be "cheaper"
salvage yard one from a wreck would likely be the "cheapest" replacement...but still $

^ He has taken a Renault transmission and successfully fitted it to his LS1. That being said, he is also doing this with a transmission to cover his rear engine configuration so I suspect his particular UN1 transmission will not work for you. Perhaps some variants of it or other like units will?

Not sure what car or skill set you have, but i have used a Toploader 4 spd @ 700rwhp for years without issue. I did build a bellhousing to make it work, here's a link to a page that includes pictures of the homemade bellhousing fabrication... http://tntrc.com

OP
doing a LSx transplant into the BMW....you would be better off getting a T56 for a LSx. The $ and fabrication to get some form of other donor transmission to "bolt up" is doable with enough $ and fabrication skills. In the end My $.02 is the $ alone, let alone time & fabrication, would be more than just buying a LSx T56. Also whatever the donor transmission is other than a T56 you need one that will handle the HP & TQ of the LSx motor. For example the NV3500 would break behind a stock LS1. So would the older tremac (Borg Wrner) 5 speeds they put in pre-93 Camaros
with that said mating another trans like a TKO may also be doable. Companies like Weir & Kesler make various adapter plates, bellhousings. More for putting a TKO or T56 on older (50-70) american muscle cars that had a period correct 4 speed tranny

Just a thought - Is finding a T56 from an Aston Martin a possibility? It seems as though this is common practice in the UK: https://ls1tech.com/forums/manual-tr...-t56-help.html
