What is an H22?
 

What is an H22 engine?

it is a prelude engine. it's a dohc vtec engine making 190 hp for the 94-96 model year and about 200 for 97-01. also there is a h22a sh engine putting out 220hp

almost

the 93-95's are h22a1 obd1's making 190hp

the 96 is a obd2 h22a1 making 190

the 97-98's are obd2 h22a4's making 195hp

99+ are h22a4's making 200hp

the type-s and sir (h22a) (jdm and european only) are 220ps~217hp the difference between the type-s and the sir is the type-s uses atts for its tq transfer system and the sir uses a LSD.

the jdm h22a's that you would buy as a jdm prelude motor is 200hp

oh the 93-96 have 10.0:1 compression
97+ are 10.2:1
the jdm h22a's are 10.6:1 compression
and the type-s and SiR are 11.0:1
thjere is no difference between the type-sh and base model preludes in the usdm.if you have any other h22 questions, im more than happy to answer any and hopefully all.

93-95 usdm are closed deck blocks.. 96+ are open deck

wow :eek: more than i ever knew about the H22 , good job

uh..yeah..i understand now..haha

if you have any basic questions, i can answer those too! lol... i had to give my h22 info out though... damn i love my engine.

what is an open block ? what is a closed block ?

im not 100% but i think its the way the cylender walls and sleeves are connected. the closed deck, each cylinder is separate, where the open deck the oil lines and whatnot are for all the cyl??????
