look at vin and look it up you can tell by VIN if its base or SH

not that this thread needs any more posts, but just for giggles, the 97-98 a4's are 9.5:1 comp and 99+ is 10:1.

this addresses an earlier post about 195hp vs 200hp. it is not an issue of auto/man or anything else. 97-98 are rated at 195bhp and 99+ are rated 200hp regardless of model and trim.

and i'm surprised no one has brought up the pressed vs floating pin yet...

chefphilip

actually the h22a4's came in the 98-01

edit: 97-01

hello all i have 99 prelude sh w/ h22a4 and i love it
Any one know where i can find authentic mugan headers and cat back exhaust with the twin loop muffler for my 99 prelude sh. Most places ive contacted online say there is a six month to one year wait.
also was wondering if any one knows the diameter of each pipe, want to avoid bottle neck

h22a are great
h22a1 are ok
h22a4 are good....for so long

when my h22a was stock, i never lost to a any other usdm h22. recently after the chip, i raced a modded 2000 lude and i Killed it!! h22a's are really good but h22's in general are good!!

sorry to get off toppic but ive been posting it every where
im trying to locate all the parts to convert my h22a4 to the jdm h22a plus some jdm upgrades the differences i know between h22a4 and h22a is intake, 11.0.1 pistons as aposed to the 10.0.1, more aggressive cams, different shape intake manifold, and im sure many other i am unaware of

^It would almost be a waste of time, the engines are slightly different but hardly.

csadams

I will be doing aftermarket parts as well only jdm but i want to use the h22a pistons to gain the compression without sleaving the block im sure there are several other pistons thst would serve this purpose but im trying to stay honda as much as i can thanks for the tip.

minilogoguy18

Well then get the pistons from the red top H22a, they are 11:1, as well as the camshafts from this motor. Go to hmotorsonline.com they have great prices on these parts brand new in the box. I thought you meant the ones from the black top H22a which are 10.6:1. As for the intake manifold go to roskoracing.com to get the H22a Euro R manifold machined to fit your engine.

csadams

yea mainly those parts from the jdm type s lude motor. Thanks for the info i was having trouble finding the intake manifold. is the intake manifold bolt on or is modifcation needed

umm, the autos cam with different cams?
I know many people think that autos had different cams, acuras, civics, so many rumors.
every time i go and look up part numbers... autos and manuals are the same part number... I have not check part numbers in this case, but would like to know, can anyone verify that claim?

minilogoguy18

Needs modification, roskoracing.com, you'll get one from there pre-machined to fit. The cam thing is probably just a bunch of internet rumors and should just be ignored.

Hello guys! I'm going to take a look at one civic EG with H22 motor inside....

I just would like to know how to see is that really H22 JDM motor....
because the man who is selling that EG claims that is JDM H22 motor... I don't wanna buy it if he is lieing ...

P.S. I'm new in cars and motors... so excuse me if i ask Newbi questions :D
also, sorry for poor english :/

thanks!

1) Don't bump old threads.

2) Look at the block stamp on the front left of the engine block, below the distributor. If it says "H22A" then it is a JDM motor. If it says "H22A2", or "H22A4", or basically anything other than just "H22A", it's not JDM. Google is your pal.

nofak

Then it should be locked if it is forbiden to bump old posts >.<

2. Oh, I see, didn't know there exist H22A stamp
Thank you very much, that would be all

Well in theory, nobody ever wins then if ya can't bump old posts.

If ya search, and have a questions but don't find the answer, everyone says search.

If ya search and bump an old thread, people say what.. make a new thread. Where people will tell u to search.

I got no problem with bumping old stuff. If it's relevant. It keeps info in one place.
