Hi, what engine is the Prelude type-s ?

About prelude type-s piston set, what bore and height comparing to B18C5, 11.1 cr pistons ?

Thanks,

Pinota

 

Is the Prelude Type-S the same Prelude SH here in USA?

 

Your in the wrong forum. Try asking in the prelude forum as I'm sure they would know.

 

Prelude type-S has different piston from Prelude TypeSH, Type-S is their R version.

 

Prelude Type S has 220hp coming from different Pistons, Cams and a slightly different ECU. Ashame we get left out of the better things here!

 

no, the Prelude type S is the top of the line JDM Lude (H22).

the SH has ATTS, along with a few minor visual differences and additional features, the SH has the H22A4.

 

The TypeS H22a engine has even more significant changes than that... It has a different head casting with a revised roof on the combustion chamber. The valve angles are changed to 45 degrees vs 60 degree on a "regular" H22a head. (This is why TypeS cams tend to disintegrate when used in US heads.) Cams, valve springs, retainers, pistons, and supposedly rods too are different. The ECU is different. The head receives a mild port and polish job by hand (similar to the TypeR B18c). The block casting is the same as the US TypeSH block. The stamping on the TypeS H22a block is "H22A" just like all other "regular" H22As. The tranny is the same as the US TypeSH with ATTS integrated. The gearing is the same.

The Prelude Type S also has several structural reinforcements to the unibody itself that normal Preludes do not have (again similar to the ITR). It also has a upper strut tower bar standard. It has no moonroof and no radio in addition to other weight savings. It comes standard with a front chin spoiler, rear decklid spoiler, and body-keyed rocker trim.

The H22A TypeS pistons have 11:1 compression with a rather large dome on top. They have the same bore and stroke as a "regular" H22a, 87mm x 90.7mm... No way in heck that's gonna fit in a B series motor if that was what you were getting at...

I have to correct you on that there is a prelude motor that that is higher then the Type S i want to say its called the SR but dont Quote me the name, it comes with 240 HP.

 

If that is the case show,, me i have never heard of such a motor!!!
The SR if i am not mistaken was the canadain verson of the h23!!
Evan the 2.3 vtec that the UK and japan gets only puts out 220ps!!

 

doesn't sound like you're very sure of yourself there...I have also not heard of a 240 HP H22. If you can provide some links or something that would probably help.

 

The only thing that i am not sure of was the name of the motor and i will have some stuff about the motor in the next couple of days.

 

could he be thinking of the Sir? I think it's the lesser JDM version of the Prelude. As far as I have always heard and read the Type S is King.

 

Type-S is the top of the line Stock H22a....240hp? Maybe you're thinking S2000? check jdmhondaparts.com type-s is the big boy..

 

i have been to jdmhondaparts. and why the hell would i be talking about the S2000 thats not even close. The motor that i am talking about is really rare and hard to find and i know a guy that has that connection i will have the info on the motor tomorrow night for all of you that dont believe.

 

No need to get angry, I'm just saying there will be alot of people really surpised if you can actually find this motor.

The 2.3L Accord DOHC VTEC engine is rare...but it's not 240hp...

 

what would the type s run the quarter mile in?

 

14.6? I'll add 20 more whp to my lude and let you know
