i have two 89 civics HBs one with a D16A6 and one with the D15B2.. i was hopping to drive the one with the D16A6 in it and make a racing engine out of the D15B2 but there's a 15HP difference, could i mix the two together ( D15B2 block with D16A6 head and intake)??

 

but its a D series.....

 

Yes the head will swap over if something is wrong with your D16 block. Clearly you want the MPFI system for any sort of racing.

 

well whiile engine could i swap into my 89 honda hatchback that would make a V8 killer? i normally work on v8 but ive been these civics kill them

 

B16, b17, b18, h22

 

where can i get a h22? what year and models have them?
can the cpu in my civic work for it or will it be a full change??

 

H22A is probably the HARDEST and FASTEST engine you can swap into that year civic. I believe you want the engine and tranny of a 92-96 prelude, someone would have to check on that tho im not 100%. Need a p13 ecu or s P72, no vtec P14.

anyway i bought a magazine that has every swap of every civic and all about how to do it, Honda Engine Swaps by Aaron Bonk, you can find information on these swaps easily yourself, just do some research.

 

what year of of prelude would have the h22z4?

 

There is no H22z4. There is an H22z1, but it's Australian. Good luck finding/importing one.

The H22a4 is practically identical. They say the difference is 3 hp. You would find it in a USDM/CDM 97-01 Prelude base or Type SH model.
