H22A & H22A TYPE-S whats the difference???? - Honda Prelude Forum

myke · 01-29-2003, 05:14 PM

Is there a difference between them? the regular H22A has only 200hp and the Type-S has 220!! is there any thing that can separate them just to know if its the actuall Type-S besides the red valve cover???

I bet a search will reveal all. . .

Type S camshafts are main reason but Searching would provide a better explanation

red92si · 01-29-2003, 07:41 PM

More aggresive cams, higher compression pistons, more aggresive fuel and timing curves, better intake design, better exhaust design... those are just the basics.

Please a search, it ill tell you everything you need to know.

the way to tell is to measure the maximum lift on the cam lobes

12.2 mm Intake
11.2 mm Exhaust

Also a slightely higher compression ratio...

yohan420 · 01-30-2003, 07:45 AM

the higher compression comes from the bigger pistons, does the better intake & exhaust come from a different head or can the H22 non type-s be modified for the same gains or better with aftermarket shafts/pistons? ..

I've seen a lot of people raving about skunk2 and crower stage2 cams for the h22x and with higher comp. pistons its pretty much type-s ..

but to answer the question exempt what i said above ... cams, and pistons give the type-s engine more power. I dont know about the ECU having a part in this either ...

Most people have agreed that building up an H22 works out to be better/cheaper than a type-s .. and if you get ODB1 then you dont have to worry about losing gains from the ecu leveling your mods out.

hard to say, I have a feeling the type-s underrated the hp....

Anyways these are the differences, as already discussed

Type-S Intake - better intake velocity
Larger TB, ported IM
Ported head
Type-S cams - higher lift - longer duration
Type-S valvetrain
Type-S 11:1 Pistons
Type-S Redesigned header - better shape at the 2-1
Type-S better fuel and timing

do the h22 type S cost much more? also, what h22a# is the type s and regular, for example, fill in the following blanks

Type S - h22a#
Normal - h22a#

which numbers designate which engines? i always hear h22a1, h22a4, etc.

All JDM engine codes are straight H22A, you can't differentiate the engines by code...

Type-S or the SiR spec-S are more expensive....like $1000-2000 more

vipastyle · 01-30-2003, 04:28 PM

well then why do people say h22a1/a# whatever? usdm?

H22A1 = USDM 4th gen
H22A4 = USDM 5th gen

H22A = JDM all years

oh ok, but are there any differences b/t them except for where they bolt etc.. of course..

where they bolt? what?

soon2bsh · 02-28-2003, 03:09 AM

so you guys are saying there is no difference in engine codes.
so a 94 jdm = h22a
and a jdm 99type-s = h22a

damn that sucks....
my friend want to buy one...but that sucks that he wont be able to tell if its say just a sir or a type-s

yohan420 · 02-28-2003, 10:09 AM

sir is h23.

what? a sir is a f20 from an accord. this has been brought up a ton of times. it has been decided that it is better to must get a regular jdm motor and modify then to get the type s engine.

soon2bsh · 03-02-2003, 08:08 PM

???? sorry but this is quite confusing......let me set this straight

ALL JDM H22A "NO #" = the Type-S, correct?

94LOOD · 03-02-2003, 09:09 PM

yes jdm is straight H22A
