Would this yield noticeable results vs adapting to the 3 bolt TB and stock setup? As I'm on a budget (aren't we all?) I'd much rather spend the ~$25 for an adapter than the ~$240 for the x-link plus TB if the end result is the same. The truck is tuned already, if that has any bearing (understanding it will need to be refreshed post-install).Īdditionally, I've read some swap to the larger TB and need to purchase an x-link to make it work. Herein lies my question, I've read the stock injectors on the LQ4 are just barely capable of handling the stock setup, so should these be upgraded to higher rate at the same time as the install? If so, what poundage should I be looking at? I'm not looking to boost or anything I would think would need a huge increase. Not a big deal as I was looking to swap over my injectors to avoid needing adapters.
#Tbss intake manifold install
I'm currently looking to purchase a TBSS intake via Marketplace for install on my '03 LQ4 and it's missing an injector (and TB as is typical). anything less than that (say under 600 WHP roughly without specifics) then the 90mm will do you perfect.I understand this topic has been discussed ad nauseam, but the forum search and links to other forums yielded conflicting results (and also missing photos, thanks photobucket). now keep in mind, if your one of the few going for a big money big power build, like high boost levels or a big cube motor, theres a 102 MM throttle that will gain you a few more HP in those extreme cases. and typically switching from the cathedral truck w/ 78mm opening to a FAST LSXRT yields about 15-18 WHP w/ 90mm TB. as for the dyno/power level question- in the past, typically we see about 10-15 WHP gains on a 500 WHP motor switching from the cathedral truck intake w/ 78mm opening to the TBSS intake paired with a 90mm TB.
