Prelude Type S
Factory port and polish job from factory. 11:1 compression and has ATTS (active torque transfer system).
http://asia.vtec.net/beystock/honda/preludes/
Prelude SIR S spec:
Same engine as the the Prelude Type S. The only difference is that it has a true LSD that is torque sensitive.
Tranny code: T2W4

Here is the site that will tell you everything about the type s and the sir spec s. Ofcourse you'll need to translate the site to better read and understand the information.

H23a vtec
http://english.auto.vl.ru/catalog/11619/
200 ps (147.10 kw) / 6800 rpm which translates to 197hp
22.5 kg*m (220.65 N*m) / 5300 rpm translates to 163ft/tq
also look at the bore and the stroke. It redlines at 7200rpms.
As a side note: The accord that this engine is in has the same tiptronic transmission as the automatic fifth gen preludes.
F20B
Believe it or not it has the same head as the type s and sir spec s. It does not share the frm sleeves as the h series. it has iron sleeves. Iron sleeves make it easier to bore out.
The bore is 85mm and the stroke is 88mm.
Now there is a catch to this motor. The automatic S shift accords that have this engine only have a 180hp because the tranny cant take too much load. But check this out... its the same auto tranny that comes in the NSX. Hmmm... The manual accords came with 200hp and 147ft/tq. But the trims has the same engine. So how come one was rated higher than the other? It's very simple. The ECU has to be different.

Now that we've discussed the blue tops. Well what's different? Absolutely nothing but the engine codes and the ecu's that are used. The F20b is the same as a h22 and h23a vtec. It's just a lesser bore than it's counter parts. Don't let the engine code fool you. It's H when it boils down to it.
Euro R h22
Single runner intake manifold. hence it makes the same power as the h22 type s.
Now for the difference between the Red Tops.
Prelude SIR Spec S and Prelude Type S is the exact same engines. The difference is that the Type S as ATTS instead of an always working LSD That the SIR Spec S does.
The Euro R Accord also gets a true LSD from factory that gets a little better forth gear than the SIR Spec S. All H22 have the same final drive of 4.266 however.
Some might be asking Ace why do you always spell out SIR Spec S? Well because in 1991 honda intruduced the 1991 prelude SI Vtec and prelude SIR in Japan. Both trims had a h22a vtec engine that made 200hp and 156ft/tq. Ofcourse this didn't See the US market until 1992.
