ok here is thething. I was building a boosted b18b ef hatch and I bought and swapped in a b18b that has je low comp pistons. Eagle rods. Moroso tapped oil pan. And arp hardware along with headstuds. I parked the hatch and picked up a daily drive cause the hatch needs a wheel bearing and new ef to b mounts and a new crossmember for when I boost. So I pick up this daily driver a 1989 prelude si with a jdm h22a swap and h tranny in it. The hatch weighs 2200lbs with me in it and it's gutted. This prelude feels a lot heavier I'm guessing around 2800? So now I'm thinking maybe the h22 in the prelude is a better boost combo. The prelude is lean but the hatch has some dents and **** in it. I already have everythibg to turbo the hatc except the intercooler piping and rossmember cause they sent me the wrong crossmember. So my question is just buy a new manifold and intercooler piping and boost the prelude h22a or just order the intercooler piping and crossmember for the hatch and boost the b18b in the hatch. What would you do? The motor in both cars runs great but the hatch is in worse condition and at this point on it would ost me about the same to boost either.

why do you NEED a new crossmember ?

 

so the downpipe will fit, this topic isnt about the crossmember anyway, i dont want to get off topic
