im doin a b18b swap in my 92 dx hatch, want to know if exhaust manifoild will bolt up? if not what will i need to do? also if i get a aftermarket header what header should i get? can i get a b16a or b18c or itr header? and what design would be best for the b18b, 4-2-1 or 4-1? Another question is what intake should i use on the motor short ram or cold air? thank u

 

Calm down there....what exhaust manifold....the B series will bolt up...I believe the exhaust has to be modified. The D series will not bolt up to a B series...
EDIT: Personally...I would keep your stock intake box...We dyno'd both a AEM and OEM and the OEM had better torque figures down low...where my D16z6 needs it. Once you really start opening the sucker up then you will need an intake. With my stock intake and 2 1/4in. exhaust on my sexy hatch with Azena's I run a 14.9....I LOST THE TIME SLIP....FOR THE HATERS....

 

i was wondering if i got a header should i get a 4-2-1 because the b18b has a lot of midrange and torque or hould i geta 4-1 to help it breathe better top end. also for an intake same thing, should i use a short ram for midrang or cold air to help tp end... thanks again

Thats your call, you know what they do, decide if you'd rather have more mid-range or high-end power.
