I have a friend wanting to switch from his s-trim to a ysi on his 94 Z. I was wondering what all you have t change to make it work? Can you use the sme brackets? If anyone has any pics and some info it would be nice.

Thanks!

 

The YSi is a pretty healthly blower for a big block, any reason why he want to go so big? A T-trim is good for 400-650 rwhp. Does he have plans to make more than that? The T-trim is a drop in replacement, the YSi would probably bolt up with some generic small block mounts but I bet there would be clearance issues with the factory serpentine belt set-up and the pulley will probably be where the electric fans are. Unless he is doing some high end 396 build I wouldn't run it, The power would be up top in the rpm band and it takes alot of HP to turn a bigger blower.

 

yeah he already makes 550rwhp with the s-trim @ 10psi. he looked at the t-trim upgrade, but wants to go with the YSi. He has plans to make around 850rwhp+. i have heard of a few people with the ysi on Lt cars. Just didn't know what they had to do to make it work.

 

I think the general consus when upping to the Ysi is a custom blower bracket vs the stock vortech brackets (the Ysi will bolt in) to keep the blower in there solid, and also to go with a big block hub on the crank along with getting the timing chain cover machined for the bigger hub and seal. Do a search on this forum. You'll find posts about it along with some pics too.

talk to victory racing, we worked together to design a bolt on ysi kit for the lt1 using the vortech cast aluminum brackets

 

Care to post more about this setup?? Do you have pics?? what do they do about tubing?

Thanks
