Default Lsxr vs lsxrt
i know ive read a little about it on here somewhere but a search is finding nothing. im lucky enough to run either one, and have a few guys interested in my ported fast 90mm setup. im just looking to go to a stock 102 setup with a 90mm throttle body. what are the differences?

Since you have enough room to run the LSX-RT, you would ideally go with that. You'll end up with more power across the board - the only downside is that it looks a little goofy since it is so tall, but the increase in performance would probably more than offset that.

Evidence?

not meaning to call anyone out on their answer. just looking for a little substance to the answer. hard data/experience is always nice

They did, LSXRT +50hp over the stock one

LSXRT makes more power than LSXR. I've tested it myself. The runners are straight in LSXRT and it has a lot more plenum volume

The truck specific design has the taller runners for low end torque. Its more of a hassle to run the LSXR on a truck motor because you need to relocate accessories. The RTs go for cheap with little miles or just dyno runs on them

it would actually be more of a pain for me to swap BACK to the truck style. im already running a ported fast 90mm on my truck.

So the LSX-RT is better than the LSX-R. Is that for trucks only or can you put it on cars too? I got the outlaw hood on my TA and it has plenty of room.
