Building up an LQ4 and was wondering if an LS2 90mm intake mainfold will work? With some tuning?

2000 rcsb z71. Bought it from my dad, the original owner! 100k on the clock. corvette servo. soon to be tuned!!
1990 2wd rcsb. stepside. lowered 2 and 4. cowl hood. molded roll pan. 89 BMW recaro leather seats, dakota digital guage cluster. LT1 swap: ported and polished 96 corvette heads, LT4 hotcam kit, pcmforless tune, nv3500 5speed, corporate 14 bolt rear with spool and 4:11 gearing.
I've heard of many people using the LS2 intake on a 5.7 and losing HP but the LS2 is a 6.0L just like the LQ4/LQ9 and it was designed for the airflow of the 6.0. I haven't heard if it works better on the larger engines than an LS6 intake. That might be a good search for LS1Tech.
See my truck data in the "My Garage" section here... http://www.ls1truck.com/forums/my-ga...tml#post191709
the LQ4 having 9.4:1 compression and the LS2 with 10.9:1 compression
and hardware to support like combos might have reasons on why a
certain intake works better than others. like red said air-flow has alot
to do with what happens.
also the LS2 is fly-by-wire... no throttle cable if you are using a throttle
cable, then a FAST 90mm throttle body is in your destiny... $400.
id say a no gain would be had for the total cost involved.
even the LSx crowd is debating on the FAST 90/90 combo and its
"need" cheaper power would be the L76 head/intake but only 355hp
on stock applications in austrailia vs 300-345 on OE parts.
on a forced induction full-tilt power ring id be a great upgrade...
daily driver... there are other better upgrades.. IMO
