tbss intake and 243's installed
 

well added some stock 243's to the LQ4 to help the cam and the truck feels smoother. i guess from the slight bump in compression. ive read that each point moved up is about 8hp on a ~400hp motor. what about torque? best time before the heads was 13.1@103 with a 1.9 60 on toyo's. keep in mind thats full weight with spare/system/hitch. my goal is for 12's :punch:

How's drivability? Performance? We need more details :D

drivability has got better if anything, truck just feels smoother all around. x-link works like a champ no probs whatsoever with the tb. truck runs great, i need to hit the track for my 12 sec slip!

Ive been thinking of adding 243s to my lq9

good to hear Mike and good luck with the 12's.
i know it's got it for sure!

so with changing to a tbss intake, it allowed you to run a 90mm tb right?

correct the tbss intake is setup for a 90mm tb!! got one if ya need it

you guys installing these tbss intakes thought about porting them before install?
the tbss guys have gained more with porting them.andy with adm performance ports them for $199 i think.removes over 2 cups on material.
i have one for my ss but yet to install it.

oh and a side note id prob stick with the tbss throttle body and not the ls7.it has been proven on a dyno that with the ls7 tb you lose hp/tq plus a wacky throttle.

thanks man, we will see on wed night.

yep ls2 portworks or formato will port it also. i did all the research but i was hurting on time since my truck is a dd. i will get it done eventually

who makes a 90mm dbc throttle body for the tbss conversion?

Never heard about this, I ran an x-link on my "car" 90mm without any noticeable problems, you have a link with more details?
