OK. The Prelude SiR and the Accord SiR both came with blacktop H22As, not blue. After 1998, the Accord SiR came with an bluetop H23A (VTEC). The Prelude SiR S-Spec came with a redtop H22A, just like the Type S. The Type S transmission is the same as the Type SH transmission, so it came with ATTS, not LSD. The Prelude SiR S-Spec transmission came with LSD. Therefore, the Type S will NOT work just fine with a regular transmission. Modifications would have to be made to eliminate ATTS.

So as you can see, everything you said was completely wrong. Are we good now?

Ok, well I must say you are right on the dot with everything dude. The Type S motor was used in 3 different cars, the 2 preludes you stated, and the accord euro r. Now on Hmotors, they have the Type S motor that comes with the LSD Hydraulic Tranny, that's the one I was talking about. Not the ATTS one lol. I know that would never bolt right up. I must say you know your valve covers as well, like I said I wasn't too sure with the valve cover, but I do remember seeing it with the h23. Thanks for the great info

For the record the Type-s motor is NOT the same as the Euro-R.

Awesome results bro. You got yourself a healthy H22.

That is a good result, thanks for sharing! What did the ignition timing end up at? Would you mind sharing your rom? It's probably not easy to tell for sure whether or not it's a Type-S without measuring the cams or pistons. It might be possible to pull a spark plug and measure how deep the piston dome is at TDC and compare to other H22's.

You're still confused. The redtop H22A that was used for the Prelude Type S only came in 1 other vehicle, but with a different block. That would be the Prelude SiR S-Spec. Same head but different block to account for the LSD. So, the engine you see on HMotors is most likely that, the SiR S-Spec. Many online distributors get them confused as you did.

Not sure what the ign timing ended up at.. and I suppose i could ask for the rom to share with you, maybe he'll email it to me.

The motor is a black top btw, and i might actually pull the plugs to know for sure, are there any threads with details regarding the measurements??

What have respectable bolt-on H22s made there?(Megan mods don't count)
Tuning is key for sure!
I'd be curious to see how this setup would "trap" at the strip.
Is there maybe mods you don't know about internally?

Ah, well as I have read, they both have different IMs, and it seems the euro r is the more favored IM. Are they different in any other way?

ragethemachine86

A prelude with jdm h22 i/h/e and a few minor mods made 182whp the week before, that's why the tuner was so impressed with my motor. He had never seen a stock motor with just intake make my power...
And there could certainly be internal modifications that i wouldnt know about. But I sure don't know a good way to tell. Regardless I'm happy i got stuck with this motor :D

ragethemachine86

And btw I know the type s relies partly on its better flowing IM and a few other parts to make its extra power, and I'm using stock usdm parts, I carried everything over from my usdm car.
I'll be getting a header and custom exhaust in a few weeks, not sure if I'll be able to afford a re-tune right away, but I'm excited to see what I'll make.

I won't spend more than 4-500 on a header so i think I'll consider the ESP header or a better used RMF etc. Plus i'll be choking it all out a bit exhaust wise since i dont want a loud car, I was in love with my h22's boosted melodies but NA is not exactly my cup of tea.

Nice numbers

Vipers4Life

Aww, why do you gotta cheap out on the header.....which exhaust do you plan to get?
