like the title says.. i have a 90' 4 door accord with f22a4 soon to be boosting and running 8-9psi allday.. my shop boys say i will wax any h22 accord by 3-4 cars easy.. and i can get a JDM h23a replacement engine for cheap.. lemme know some numbers so i can look at possibly tuning and small add-on parts to improve perf. thanks guys

 

jdm h23a? you mean the accord wagon motor out of the 99 overseas model? dohc vtec 2.3 or you mean the h23a out of the prelude si chassis from 92-96? just curious cause the lude motor is a usdm motor and a jdm h23 vtec swap would be SUPER rare.

i am to be tuned at 10/12psi on the f22b1 soon hopefully, but no 1/4 mile times yet cause the track closed.

 

well i got a boosted h23 lude. It's just a t3/t4e @9 lbs untuned ( Just hondata Basemap) I'm pretty sure you would be able to beat any h22 accord but only from about a 40mph roll. On my street tires i couldn't get traction till the end of third gear. but still managed to pull off a few 14.6's @102mph.

well my shop boys say his buddy in Toronto, Canada (i live three hours east) has a jdm h23a (non-vtec... i think) for 600 CDN with no tranny and ecu .. but i know a guy that has a spare h22 tranny and depending on the year of the motor (whether it is pre OBD or OBD1) i can use either a b18b ecu or if its pre OBD i have to use something else.. stock h23 if i can find one.. my buddy said the engine produces same as b16 about 160hp with a **** load of torque and his boost happy with low compression!.. should i go for that.. or stick with my f22a4

 

lol, this is funny.. boost ur stock motor i wanna see how fast you blow it up.. i'll put money down you will have thrown a rod within a few months.. also.. there is no "JDM yo" h23a.. if its got 160HP then its the h23a motor out of a stock prelude.. and no it doesn't have "m4d" amount of torque.. same as the h22a about 150ft/lbs
and no h series is preODB.. you need to get you facts straight.. your "boys" aren't making you look good neither is your grammer..
just cuz its low compression doesn't mean its boost happy.. some say the f series motors are good for boost.. however i've tore down a couple and those puny rods won't hold up.. the h23 isn't much better eirther. i've seen/heard of those blowing up as well under boost.

 

hmm interesting screen name 4genACCORDFREAK


12psi stock f22b1 daily driven.. 14psi whenever i want to play around.... f22b1 aren't that weak


keep the f22a if the compression numbers are good

well then what motor came stock in japanese 92-96 preludes?

 

a dohc f22 w/9.0:1 compression and about the same hp/ torque output.... 160hp/148trq

edit btw funky how for some reason the usdm h23 never made it to the jdm huh? got to love hondas

 

theres a guy on homemadeturbo.com that ran 20 psi through his F22a and the first thing thatw ent was the ringlands and not the rods. Msot of the F22 bottom end is forged. Only thing that holds it back is the shitty bore/stroke it inherited from the damn H22's.

hmmm well in fact their is a JDM H23a vtec, it got 200hp/163trq with 10.6:1 CR

well if they don't exist, I wonder why a guy in my accord club would have it in his car!!??!!

he's n/a and doing flat 15 with some bad tire on a 4th gen accord

so if you can get a real h23a jdm dohc vtec for cheap, do it, it's a great engine, more torque than the h22, love rev and is closed deck (ain't 100% sur about that one)

 

if i'm not mistaken doesn't that jdm h23vtec only come in automatic?? That motor never came in a prelude. It only came in the jdm accord wagon i believe. Also i'd rather just by a usdm h23a1 from a 92-96 prelude Si and build it.

 

hmmm don't know about the tranny, but anyway all H/F trannys can fit, that motor was in the Accord wagon, it's a rare motor, so that's why i'm telling you if it's really that motor, then get it!!! the guy may not know the real price of that engine!!

for the h23, yup, the only difference would be no vtec

yeh i think they only came automatic , ill just do a h23a1 to

 

6thgenaccord1 is making 230whp and 233tq with an fmu setup @ 6psi. he's getting hondata and injectors soon and will hopefully be making 300whp @ 12psi

 

i will find out all the details about this "jdm" h23a business and if it is vtec or not.. i did not really ask much about it.. cuz my shop buddy (who is a damn genious with honda's and turbo's) he just said it would be a good replacent engine if i blow my f22 since it has like 240km's on it.. so i'll find out more and let you all know if its the REAL DEAL
