.... also has an insane compression ratio due to thier dome pistons, i think its something like 11.0:1 or 11.5:1 either its crazy high....
also Prelude Type-S (which by the way only availble in Japan) has different gear ratios and LSD.
Peace,
Jose
it happens, just try not to do it much unless you in OT.
5th Gens never came with SOHC engines... SiR is the 4th Gen sold in Canada... as far as the engine i'm i dont know...
you are mistaken sir
canada has the s, sr, and srv
america has s, Si, and Vtec
but that's only 4rth gen, and this is the fourth gen forum so that's all that concerns me
there are no SiR 4th gen in north america

oops, I knew there were no SiR in NA but i just didnt know where... sorry guys

there not all 5th gens. the type S is the only 5th gen there listed, the rest are 4th gen.
please stick to the topic, or go to OT.
I know you're a mod, and I'm really sorry to rain on your parade, but all the ones I listed there are Japan spec 5th gen Preludes. 5th gens were still offered with F-blocks over there, as well as 4WS.

really? I was not aware that the 5th gend came with an f22a engine....I guess you learn something new every day huh!
"SIR" is also 4th gen, I believe the 'VTEC' version of the 4th gen Prelude was called an "SIR" in Canada, might have also been called an SIR in Japan/Europe?

VTEC version in canada is called the SRV.
As for the 5th gens, the main difference between the Type-S and the SiR-S spec is that the Type-S comes with ATTS and the S spec comes with a helical LSD. Both use the same 220ps motor.
for everyone in confusion here are the main differences:
the type S and SiR are both 5th gen japanese models using the same H22A motor. however the type S is an upgraded type. honda has 2 types of specially made race cars, one is called Type R (like the civic and integra) and the other is the Type S (like our preludes) both have the same engine upgrades the only difference is that the Type S is limited to only the engine upgrade while the Type R is fully race modded (interior, suspension, minor weight reduction, etc.) Type R and Type S motors come with different piston heads which increase the compression (11:1 in Type R integra and Type S prelude), different rods, valve springs, kick ass camshafts, and a port and polish job, along with the ever so famous red valve cover. so those upgrades are what makes a Type S prelude different than the SiR and gives it the extra 20ps. it is also what makes the Type R motors different than the ordinary motors of their corresponding lower models. the SiR is slightly modded but not close to the type S and has the blue valve cover. and the LSD and ATTS differences were already mentioned by someone else

This is not entirely correct. The Accord Type R has a blue valve cover.
Also, the heads don't really receive a full port and polish. It's more like the casting marks in the head are smoothed out, and the valve seats are blended a bit. The head might be ported some, but from the engine builders I have talked to, it's hardly a P&P job.
Also, as far as I know, the rods in the TypeS and USDM Preludes are exactly the same.

Can anyone confirm this?
