To do this swap you will need either a phenolic adaptor or cut the flange off the HO mani and weld on a metal 2.4 Flange. The 2.4 has B shaped ports, while the 2.3 has oval.

For the cams, you will also need the cam housings and bigger lifters. The exhaust side is drop in, but the intake side will need the intake cam machined to accept the 2.4 power steering.

Further, you will need a tune immediately to unlock the power of the cams. You'll hit your redline before you complete your powerband. Also if you have a 99 or older 2.4, you will have to delete the EGR, as the HO mani blocks this. (00 + did not come with an EGR and just has the big gaping hole on the head)

the manifold is rumored to lose 10 whp on N/A motors (i'd personally like a retest under different variables)

the cams basically need a tune to get the real gains out of it... do you know someone with HP Tuners?

sorry to bring this back up but I have found a 2.3 HO intake manifold for myself and have a few questions.


is there gains with this intake manifold? im not doing cams just the intake mani.
Has anyone done this and liked the results?

its all ready to bolt up to the 2.4 head he told me all that needs to be done is "The intake manifold will require alittle modifying. Vaccum lines will need to be lengthened, and the brake booster line will need to be cut, and Air intake needs to be cut aswell cause the throttle body is in a different position. Other then those small things it will bolt up to the head with no problem and throttle cable fits and all sensors work perfect"

I have done a fair bit of searching but havent found anything solid. here she is

89-94 had the correct intake manifolds and cams. 90% of beretta gtz's and 892 94 z26's, grand am gt's, Calais', and acheiva's.

and it doesnt matter, some LO's came with the HO intake manifold. you just gotta look at it and make sure its the right one.
