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