i tried looking up the type S but couldnt find it, but whats the difference btwn that and the type sh ??? thanks

 

Type S is in Japan
Type SH is in the states

 

Hi

I have been doing some research into the Prelude Type S as I'm looking to purchase a 1996 model down here in New Zealand.

Basically the key thing is a type S has the Red top H22A 161kw engine - as in the later Japanese Torneo/Accord Type R, and the Prelude Type S has the ATTS system. I have diagrams, specs, pictures but don't know how to post them. Another good resource is the honda fact book on ttp://www.honda.co.jp/factbook/auto/index.html [it's in japense but you can work out the specs etc from the tables].

Here are some facts I found using google search for Prelude Type S:

In order to produce more naturally aspirated power from an already powerful engine, Honda realized that it must improve on such things as intake resistance and heat dissipation. The H22A engine received yet another dosage of Honda's racing technology and custom engine work. Though not as widely known, the Type S engine, like the Type R engine, receives a port-&-polish job from Honda.

Improving on its already sky-high 10.6 compression ratio, Honda created a new pistonhead that increased the compression ratio to 11.0. By doing so, the burn-off response increased, helping heat dissipation, as well as improving torque throughout the powerband. The VTEC valve timing, lift, and duration were also adjusted as well. The valve lift on the intake reaches 12.2mm, while the exhaust end reaches 11.2mm. As far as production engines go, these are really high numbers.

Honda felt that it would need to improve on the intake path to compliment the increased high-end performance. The air intake box was made into a funnel shape -- utilizing what Honda calls "dynamic chambers." The throttle body was also bored out from 60mm to 62mm. Even the material used in the inlet manifold was changed to a more fine, granular one in order to make it more smooth. The valve seat was re-adjusted from 60 to 45 degrees. Finally, the cylinder head and intake port was treated to a manual port-&-polish job by Honda technicians. Honda is making these engines as if they were meant for the track.

By lowering the intake resistance and making an engine that burns efficiently, Honda needed to finish its tuning job by allowing for the exhaust to get out smoothly. The exhaust manifold, while retaining its outer diameter, had its opening size increased. The dual-pipe design to follow was made truly cylindrical, (as opposed to oval) and the wall lining was made to 15mm -- decreasing exhaust interference. The catalytic converter was also increased in size, and the exhaust piping increased from 50.8mm to 57mm. The silencer efficiency was increased from 97 liters/second to 113 liters/second. This completes the improvements made on the air flow efficiency of the Prelude Type S.

thank you for taking the time to post all this stuff up really helped thanks

And I'll take a crazy stab in saying that it probably equates to 161kw...

 

Well spotted.

I mixed have corrected the post - now reads 161kw.

kitboi where do you live because the japanese/euro type S is not the same as U.S.models. here are some comparisons i found by using the greatest tool on the website "search"

https://honda-tech.com/zerothread?id=666693
https://honda-tech.com/zerothread?id=1081801

if you do not live in the U.S. then i dont know if these threads will lead you in the right direction so you should specify that...

 

in short.

type sh sold around the world
type s sold in japan and i believe euro for certain years.. (correct me if i'm wrong)

type sh 200hp w/ atts
type s 220hp w/ atts and active control abs/lsd and other "luxury" goodies. (dvd navi, leather optional, etc)

this link is for tech specs for type S
http://asia.vtec.net/beystock/honda/preludes/

i remember i visited this really good site showing all the 5th gen preludes.. but i can't find it... i think someone on h-t knows what i'm talking about.. it has pictures of every model, si-r, sh, type s, base.. etc etc.. and it shows what you can option it out with.

I now know to look closely at the FAQ.

there are like 7 different versions of the 5th generation prelude in Japan.

SIR
SIR-G all sorts of crazy ****. 5th gen with navigation, rear windshield wiper, h23 ( yes in a 5th gen chassis) seat heaters etc.. japan and other parts of the world just get cooler cars.
