My question is this, I seen this on
DOHC_tuner sig

is there any advantage to it?
is it hard to do?
what car did it come off of?
how big is the throttle body?
I guess that is 4 questions........
any help would be good, getting my motor ready to go in.
1996 2.4 is the motor for those who haven't seen it in the newbies section
Yes and no
No
Early 90's GM cars, Mainly N bodies
stock? 56mm
Its the High Output Quad 4 intake manifold off a GTZ Berretta. Unless you have boost or a great flowing head with bigger cams and exhaust I would not recommend it.
You'd be better off with either the LO Quad 4 manifold or even the stock manifold if your LD9 is stock. Or try the Venom or OBX manifolds.
GMR has got nothing on this
